Sea of ​​Japan (also known as East Sea) The phenomenon of space debris falling to the ground and causing damage was first recorded in 1969. That year, Japanese diplomats informed the United Nations of an unidentified object from space falling from space. down and collided with a Japanese cargo ship moving off the coast of Siberia (Russia). The collision seriously injured five crew members. Not long after, a Soviet ship at that time appeared to search for the wreckage. The Japanese official said the debris was identified by experts as part of a Soviet spacecraft. However, this information was initially kept secret by Tokyo because it did not want to create a conflict with Moscow, according to AP. Northwest Territories, Canada The danger of objects from space became apparent in 1978, when Cosmos 954, the Soviet Union’s atomic-powered satellite, crashed to Earth. The incident caused radioactive debris to be scattered throughout the Northwest Territories, Alberta, and the Canadian province of Saskatchewan. After the incident, the Canadian government organized a large-scale “Operation Morning Light” to search for tiny pieces of radioactive material that fell on the Arctic tundra. The cost for this campaign is nearly 14 million CAD (equivalent to 11.5 million USD). A fragment of the satellite Cosmos 954. Photo: United States Department of Energy. Canada demanded compensation from the Soviet Union at that time in the amount of 6 million CAD (equivalent to 5 million USD), but Moscow ended up paying only half of that amount. State of West Australia, Australia In 1979, Skylab – the first space station of the US Space Agency (NASA) – broke up while re-entering the Earth’s atmosphere. The incident caused a lot of debris to fall across the farm town of Esperance in West Australia, Australia. The Skylab space station was photographed by the last crew before it broke up on July 11, 1979. Photo: NASA. “It’s the most beautiful fireworks display you’ll ever see,” Brendan Freeman, a retired farmer, told ABC. The debris did not cause major damage, but for fun, the town of Esperance authorities wrote a $ 400 NASA fine for littering. NASA did not pay the fine, possibly out of fear of setting an unfavorable precedent. In 2009, a DJ in the city of Barstow, California (USA) called for fundraising and brought the fine to pay the town of Esperance. Lakeport, California, USA Early one weekend in 1987, a retired aircraft mechanic living in a town near Mendocino National Forest in northern California heard what sounded like gunfire outside his bedroom window. After searching, he discovered a scorched metal piece more than 2m long lying in the alley next to the house. An analyst with the US Air Force determined that the object was most likely a piece of debris dropped from a Soviet missile. This rocket has previously been seen flying across the sky while burning up and falling to Earth. “It’s interesting because things like that don’t happen around here very often,” Maggie Pickle, the mechanic’s neighbor, told the AP. Tulsa, Oklahoma, USA Lottie Williams holds up a piece of debris that hit her shoulder from a US Delta II rocket in 1997. Photo: Tulsa World. One morning in 1997, Lottie Williams was walking with friends in Tulsa City Park when she saw what appeared to be a comet streaking across the sky. This object fell on Mrs. Williams’ shoulder, but the impact was very light, almost without feeling. This object was determined by scientists to be most likely a fragment of a US Delta II rocket. The fragment was kept by Mrs. Williams as a souvenir. “I had to be very lucky for the debris to be so light. It was one of the strangest things that ever happened to me,” Williams told NPR in an interview years later. East Texas and Louisiana, USA, In 2003, the US space shuttle Columbia broke up while re-entering the atmosphere, killing 7 astronauts on board. In places where the debris of the shuttle hit the ground, temporary memorials were erected for the crew. People in rural areas along the Texas-Louisiana state border reported seeing debris from the ship falling into a water storage tank or through the roof of a dental office. Someone even tried to sell a fragment on the e-commerce site eBay for $ 10,000. In the end, 84,000 pieces of wreckage from the wrecked ship were collected after an extensive search in swamps, woodlands, and grasslands. These debris were used to rebuild the ship and determine the cause of the disaster. Ivory Coast In May 2020, another Chinese Long March 5B rocket also crashed to Earth. The rocket was initially thought to have landed in the Pacific Ocean, but some people reported hearing a sonic boom and seeing metal shards falling from the sky. This shows that some parts of the Long March 5B missile fell on the village of Mahounou, in Ivory Coast. China’s Long March 5B rocket launch in late April in Hainan province. Photo: Getty. However, there were no reports of human casualties after the incident. The discovery of a piece of pipe more than 12 meters long also seems to help this area get more attention. Grant County, Washington State, USA The most recent space debris incident occurred just over a month ago, when a rocket owned by private aerospace company SpaceX exploded over the Pacific Northwest. The explosion created a “show of light,” which some initially mistook for a meteor shower, according to The Verge. A piece of equipment from the rocket fell on a farm in Washington state, leaving a mark more than 12cm deep in the ground, The Verge reported. A similar object was also discovered by fishermen off the Oregon coast a few days later, but authorities have not confirmed whether this is debris from a SpaceX rocket.

At first glance, the cafe looks like a black and white comic book page Designed with 2 traditional black and white colors, but the combination of these 2 colors has never been outdated. The image of BW Kafe cafe in Sankt Petersburg, Russia soon became famous after appearing on social networks. Russian artist Anfisa Toshina designed the unique interior inside the bar. At first glance, the cafe looks like a charcoal sketch on a piece of white paper, giving the illusion that you are the only 3D object in the two-dimensional world. It’s a pretty cool trick that looks like the backdrop of A-ha’s popular ‘Take on Me’ video. Everything inside makes customers feel like they are lost in a comic book from the entrance, to the monochrome yet stunning decor inside, with the walls, floors, furniture, and details. Other small ones have only 2 colors black and white. Each corner of the shop is a sequence of scenes like in a comic book Each interior space inside the restaurant always creates a unique, impressive, warm, calm and extremely peaceful atmosphere. This design style first appeared in Korea, by the creators of Cafe Yeonnam-dong 239-20. Since then, similar designs have been replicated. Several similar locations opened in Japan a few years ago and now Russia, not to mention the official branches of Cafe Yeonman. Although the BW Kafe in Sankt Petersburg, Russia looks like a copy of the Korean cafe, it has been improved quite well and is an opportunity for Europeans who want to admire the style but cannot travel to Korea . The special design makes customers feel like they are the only 3D objects in the two-dimensional world Customers enjoy posing in the cafe space

First, it is necessary to consider the operating principle of Shkval. When an object moves in the water, it will create bubbles around it due to its motion, which is the phenomenon of cavitation in nature. The super-cavity is a more special case, when a large air bubble appears and covers the entire object, then the object will almost fly in the air due to the maximum elimination of friction. This is the principle applied on the VA-111 Shkval super-fast torpedo. The VA-111 Shkval was researched in the 1960s as a specialized weapon for attack submarines to fight nuclear submarines and enemy surface ships. On November 29, 1977, the VA-111 Shkval super-cavity torpedo was officially accepted into service in the combat component of the Soviet Navy. Shkval torpedo uses a solid fuel engine, the head is fitted with a special cavity-forming device. It is a thick elliptical piece of metal that is sharpened with an angle of inclination to the longitudinal axis, with a circular cross-section to create an angle of elevation. In fact, a foam generator is not enough, so the torpedo head adds foaming air ducts, the bubbles are generated by a gas booster. This allows to increase the volume of air bubbles and create bubbles that cover the entire torpedo body. The Shkval super-cavity torpedo has a speed of 93 km/h out of the launch tube and up to over 360 km/h when the engine is at full capacity, twice as fast as conventional torpedoes. The warhead of the VA-111 has a weight of 210 kg, enough to break a 10,000-ton destroyer in two with a single shot. However, it should be added that besides the advantages, the VA-111 also has deadly disadvantages, making its use in combat must be carefully considered. Firstly, Shkval’s range is too short, reaching a maximum of only 6,858 m, forcing the submarine to be close to the enemy to be able to strike. This is extremely dangerous because modern warships all have advanced sonar navigation systems and extremely powerful anti-submarine weapons. Second, it is the super-cavity technology that creates superior speed that makes the torpedo unable to establish two-way communication, when the radio signal is blocked from the outside, unable to penetrate the air bubbles. The torpedo relies on estimating target coordinates prior to launch, and its maneuverability is also extremely poor, as a sharp turn would break the supercavity bubble. Third, the secrecy of the Shkval torpedo is completely absent, because it creates extremely loud noises and forms a line of bubbles floating on the water that is easy to observe. Finally, the unit price of the Shkval torpedo is said to be significantly higher than the older generation types, while the advantages are not yet outstanding. For the above reasons, guided torpedoes such as TEST-71 or Type 53-65 combined with Kalibr cruise missiles will give modern submarines a higher combat capability, especially without tethering. it faces dangerous situations like when carrying the VA-111 Shkval. Currently, Russia announced that it has initially successfully tested the Shkval 2.0 variant with a longer range and controllability. If the above weapon is soon completed, it will really be able to replace the products of the old generation.

The speed of light (more generally, the speed of propagation of electromagnetic radiation) in a vacuum, denoted c, is an important fundamental physical constant in many areas of physics. It has an exact value of 299,792,458 meters per second, because the meter length unit is redefined based on this constant and the standard second. According to special relativity, c is the maximum speed that all energy, matter, and information in the universe can reach. It is the speed at which every massless particle bound to physical fields (including electromagnetic radiation such as light photons) propagates in a vacuum. It is also the propagation speed of gravity (such as gravitational waves) predicted by current theories. Particles and waves travel with velocity c regardless of the motion of the source or of the observer’s inertial frame of reference. After Einstein founded relativity, it became known that the speed of light is indeed very fast, because this is the upper limit of the local speed in the universe, and no other speed can be exceeded. through it. Moreover, regardless of the medium in the frame of reference, the measured speed of light is exactly the same. Based on the principle of the constant speed of light in relativity and the highly accurate measurement of the speed of light, physicists have also determined the speed of light to be 299,792,458 meters/second without affecting the speed of light. affect the current physical quantity. In this way, people no longer have to worry about accurately measuring the speed of light, and can also solve the problem of errors in the equipment used to determine the clock. The speed of light propagating in a vacuum is independent of both the motion of the light source as well as of the observer’s inertial frame of reference. The constancy of the speed of light was postulated by Einstein in his 1905 paper on special relativity. Physicists can now only experimentally confirm the speed of light by methods above two Two-way speed of light is frame-independent, because the speed of light cannot be measured in one-way speed of light, ignoring some conventions of uniformity. synchronization between the clock at the source and the clock at the receiver. Whether it’s electron transition, nuclear fusion, nuclear fission, or the annihilation of yin and yang matter, these processes produce light. Once light is created, their speed will immediately reach the speed of light, and they will always travel at this speed. If light were not absorbed by matter, they would not be dissipated in the universe, and the speed would always remain at the speed of light. For example, the first photons created in the universe 13.8 billion years ago are still present today, and they travel through the universe at the speed of light. So, how did light reach the speed of light? How does light maintain the speed of light? What is the driving force that drives the light forward? If it is explained from the point of view of the particle nature of light, then light is composed of photons with no rest mass. According to special relativity, since the static mass of photons is zero, their speed can only be the speed of light. According to the Higgs mechanism of the Standard Model of Particle Physics, when photons without static mass pass through the Higgs field throughout the universe, the photons will not be coupled, so they will not gain static mass, and their speed will not decrease. Once the photons are generated, their speed will directly reach the speed of light, and there is no acceleration from zero to the speed of light. Propagation of photons does not require energy to propagate, if they were not absorbed by matter or a black hole, they would always travel aimlessly through a vacuum at the speed of light. On the other hand, if explained from the evaporation of light, the nature of light is electromagnetic wave. Maxwell’s equations of electromagnetism show that electricity and magnetic fields are essentially unified, that a changing electric field excites a magnetic field, and a changing magnetic field excites a repeated electric field, creating out electromagnetic waves. Since electromagnetic fields are formed at the speed of light, electromagnetic waves travel at the speed of light. The generation and existence of electromagnetic fields are independent of the medium, so light can travel at the speed of light in a vacuum. Although the spatial structure continues to expand, light propagating through space will appear redshift, but they will not completely disappear in the universe.

The Fukang meteorite is auctioned off. Where this extraterrestrial object originated and how was formed is still a topic of discussion among scientists. Coming from an asteroid The Fukang meteorite glows in the sunlight. The Fukang meteorite was discovered near the town of Fukang in Xinjiang, an autonomous region in northwest China, in 2000 by an unidentified hiker. Every day, this person often stops by a giant rock to have lunch and rest. Once, he was suddenly curious about the structure of this object, when he noticed that it seemed to have metal and crystal inside, so he decided to break some pieces and send it to the US for confirmation of the type. He was surprised to learn that these samples did not come from Earth, but belonged to a meteorite. In February 2005, these objects appeared at the Tucson Gem and Mineral Exhibition (USA). Here, it was noticed by Professor DS Lauretta (a specialist in Planetary Science and Astrochemistry at the University of Arizona), who is also the principal investigator of NASA’s OSIRIS-REx mission. Then, the remains of the Fukang Meteorite (with a mass of 983 kg, excluding the 20 kg mass smashed by hikers) was directly studied by the University of Arizona (USA). Scientists said that this rock belongs to the type of iron-stone meteorite, called Pallasite. Pallasite meteorites contain olivine, which is thought to come from the crust of a rocky planet orbiting between Mars and Jupiter. If not from the planet, it could belong to an asteroid with a rocky shell and a metal core. Pallasite can be distinguished by a meteorite iron substrate, embedded with silicate crystals, mainly olivine (a yellow to greenish-yellow crystal). The Pallasite meteorite is named after Simon Peter Pallas, a German naturalist. He was the first to describe Pallasite Krasnojarsk, a 700 kg meteorite, discovered in Russia in 1772. The origin of the Fukang meteorite, like other Pallasite meteorites, has not been scientifically explained so far. It is hypothesized that it originated from an asteroid with a melted and decomposed metal core and surrounding olivine mantle and formed with the solar system about 4.5 billion years ago. In addition to its rarity, the Fukang meteorite, like other Pallasites, is a very beautiful object. When shined through the olivine crystals, the light will make the meteorite glow brightly and spectacularly. Most expensive A cross section of the Fukang meteorite is on display at Arizona State University (USA). Because of this beauty, collectors have always wanted to own pieces of the Fukang Meteorite. The largest part of this meteorite, weighing nearly 420 kg, is currently in the possession of an anonymous collector or group of collectors. In 2008, the above Fukang meteorite was auctioned at Bonham’s, New York (USA) with a starting price of about 2 million USD. A curator and online auction organizer has placed the Fukang meteorite at number one in the “Top 10 Most Expensive Meteorites Ever Discovered on Earth”. However, no one participated in the auction for this treasure perhaps because the price was too high. Meanwhile, other small pieces of the remaining meteorite, have been purchased in auctions and distributed around the world. Particularly, the University of Arizona Meteorite Laboratory (USA) holds a total of 31 kg of Fukang meteorites. Their website describes the Fukang Pallasite as “the most breathtaking example of the splendor of the natural universe”. In February 2021, the famous auction house Christie’s said it had sold “part of the most beautiful extraterrestrial matter known”. That tiny piece of meteorite alone brought the seller $30,000, far exceeding the initial estimate of $3,500 – $4,500. What makes the Fukang meteorite so special? First of all, this is not an “ordinary meteorite”. Pallasite is an extremely rare heaven stone. This is because most Pallasite cannot survive falling into Earth’s atmosphere. It is estimated that less than 1% of rock falling from the sky is Pallasite. Therefore, the Fukang Meteorite is considered by scientists as one of the most important celestial rock discoveries of the 21st century. According to the Planetary Science Institute, based in Tucson, Arizona, USA, there have been about 1,100 observed and found meteorite falls in history. Meanwhile, the number found but not observed goes up to 40,000. The Fukang meteorite is among these. The institute estimates that about 500 meteorites collide with Earth every year, most of which burn up in the atmosphere, the rest fall into the ocean or in remote, desolate regions (According to Science 101).

According to Boredpanda, Gab Bois (24 years old, living in Montreal, Canada) is a photographer known for his surreal images. Although she only uses ordinary objects in life such as banana peels, nylon bags, water cans…, each of her works brings attractive beauty. With creativity, the world of fashion also becomes especially close under the hands of Gab Bois. Overcoming the barrier from material to practicality, the female photographer skillfully creates costumes or accessories that are imbued with everyday life. Crocodile headbands, mushroom bras and lily shoes are some of the pictures that have caught the eye of the internet. Food is often a subject that is easily included by Gab Bois in his work, followed by common objects such as headphones, screws… Any practical object can become Gab Bois’ creative inspiration. Besides handmade products, she is also not afraid to admit to using photo editing tools. However, her skillful skills make her works come to life as if they were taken directly. “I’ve always been passionate about fashion, especially DIY fashion since I was a child. I would help my mother remove the leaves on the cob and then I would use them to make doll dresses,” said Bois. Explain the origin of surreal fashion ideas. Sharing about the creative process, the 24-year-old female artist said that everything does not always go smoothly. Sometimes, the realization of thoughts encounters many difficulties. In addition, she also often faced the situation of running out of ideas. However, through her works, Bois wants people to have a new look at fashion. In an age where designer clothes and style are so ubiquitous, she wanted to prove that even the most trivial things can be amusing, having to look at them again and again.

It creates an infinitely curved region of space-time, from which nothing can escape, not even light. Do black holes rotate? This is an interesting but not so simple question that I received in one of my recent lectures. To answer it completely and accurately, we need a clear understanding of the very verifiable properties of black holes as well as about the nature of rotation. To date, the concept of rotating black holes is not new. In fact, every object in the universe, once having a mass large enough to be spherical, will also have a rotation. Since mass exerts gravity, every object tends to compress itself – because its parts attract each other. For small masses, this gravitational compressive force – commonly known as centripetal gravity – is so small that it cannot exert any effect on the object, because it is simply an intermolecular force of cohesion. substance – especially solids – is much larger than it is. But with very large masses, on the other hand, the force of gravity is so great that matter will rearrange until it becomes spherical. That is, the state in which the force of gravity directed at the center of the object from all directions is equal to each other. That’s how every object as large as a planet or a star gets its spherical shape. At the same time, when there is such a large mass, another problem arises, and also related to gravity. Since no single star or planet is perfectly uniform, in fact the gravitational forces in their different regions are unequal. This difference is the main reason they oscillate, and hence the rotation. Thus, all large objects in the universe rotate because of their own gravity. What about black holes? The most common types of black holes known to scientists today are stellar-mass black holes. It is formed from the late-life contraction of the cores of massive stars. These stars are usually at least 8 to 10 times the mass of the Sun. Towards the end of their lives, their cores shrink very rapidly because the fusion reaction no longer produces enough energy to resist the contraction of that enormous mass. This sudden contraction causes an explosion that is considered one of the most violent events in the universe” supernova explosion. This explosion tore apart the stellar shell that was previously in the state of a red supergiant. The remaining core of the star shrinks and collapses to become a black hole. All stars rotate on their own axis (our Sun, for example, has a rotation period of more than 25 days). It is not difficult to speculate that something formed from a rotating stellar core would also have to rotate, because that momentum is simply still there. The same is probably true of supermassive black holes – black holes with masses ranging from hundreds of thousands to billions of times the Sun, located at the center of most galaxies ever observed. In fact, when the first image of a black hole was released in 2019, scientists were able to see the spirals of the accretion disk surrounding the black hole. It shows that the giant accretion disk is rotating, not fixed. Just like the fact that all the stars in each galaxy are constantly moving around the center of the galaxy (for example, our Sun takes about 230 million years to complete one full circle around the center of the Milky Way). Two things need to be clarified before concluding that the black hole rotates on its own The entire initial mass of the black hole – in theory – is packed into an extremely small singularity. It is so small that it can mathematically be considered sizeless. That singularity has a certain radius (Schwarzchild radius) known as the black hole’s event horizon, but it is just a region of pure space-time, not an object like it has a surface. like a star or a planet. As such, it is difficult to consider something with no dimensions, or a boundary without a surface, to be rotating, since there is simply no alternate motion of points to a particular surface. No radiation comes out from within the event horizon, which also means that all information inside a black hole is unknown. If matter were indeed crushed and completely collapsed into a single point, the space within the event horizon could itself be a place of absolute uniformity, i.e. no rotation would occur due to the difference. interesting. With these two points in mind, don’t forget that what we see spinning is itself just the accretion disk surrounding the black hole. Of course, one can also calculate the rotational speed of an accretion disk based on its mass when taking into account as well as when not taking into account the presence of a black hole at the center, from which to compare and predict. It looks like the black holes in those places are spinning very fast. Even so, given that we don’t know anything about what lies within the event horizon, or even something specific happening at its very edge, concluding that black holes are indeed rotate or not and how fast they rotate is still too early. Likewise, the charge of a black hole is also a purely theoretical concept and is calculated from solving Einstein’s equations. There is no way for us to verify if an electric charge really exists after being swept inside the black hole’s event horizon. In the future, to know more about this information, we will need to look forward to new generations of telescopes and new methods to image and track more black holes with much greater detail. compared to what there are today.

Chen Li, an expert from the Wuhan Air Force Early Warning Academy, said that the AI ​​can collect small pieces of information from different data sets at various times and places, creating links between different regions. pieces of information that humans cannot see. As a result, the data collected could help the Chinese military identify the flying object as belonging to a hostile state, amateur aviation enthusiasts, or appearing for “other reasons”. The Chinese military has deployed AI to track and analyze unidentified flying objects. Photo: SCMP. The Chinese military has a three-level warning system in handling unidentified flying objects. At the most basic level, military radar stations, air force pilots, meteorological observation stations, and scientific research facilities are tasked with collecting as much raw data as possible. This data is then processed at the regional command level, before being transferred into a national database. With the help of AI technology, the Chinese military can build a set of “threat index” to evaluate flying objects, based on behavior, frequency of operation, aerodynamic design. , radiation levels, construction materials, as well as any other indication of the object. To date, China has only once officially confirmed the observation of an unidentified flying object. The incident occurred in the airspace above an airbase in Cangzhou, Hebei on October 19, 1998. The object is described as a mushroom, with two beams of light in the abdomen. When the Chinese fighter tried to approach, the object flew very quickly to an altitude of more than 20,000 m, then it disappeared from the radar screen as well as the pilot’s view.

The trick that is considered very dangerous today is that reactionary objects fake official information pages, using tricks to create fake websites, fanpages, blogs, facebook, taking the names of agencies. , individual leaders of the Party, State and a number of departments, ministries, branches and localities to spread fake news, bad news, toxic, to cause conflicts, internal divisions, even many websites and blogs Facebook posts information and images very deeply about internal issues, causing skepticism and confusion among officials, party members and the people. For example, the recent fake fan page “Central Propaganda Department” is an example. This fake fanpage has attracted hundreds of likes, hundreds of followers and posted unreliable information. More dangerously, on the social network youtube, with just a simple search, users can access thousands of videos with content related to Party and State personnel; fabricated, slanderous, libelous and defamatory information about Party and State leaders. However, many of these videos, although presented as a news report by the media, in fact the content inside is speculation, fabrication, and false information about standardization work. congress, especially the Party’s personnel work. To create trust for viewers, the subjects are also willing to create their own logos, using images of Party and State leaders, and then attach them to sensational headlines. Leaders of Thanh Hoa Provincial Police spoke at a meeting of the 35 provincial Steering Committees on protecting the Party’s ideological foundation and fighting against wrong and hostile views. Not only appropriating the people’s trust, the deeper purpose of reactionary and hostile forces is to sabotage the Party and State, divide the Party and State with the People, and sabotage the great unity bloc. nation. Detecting and identifying sophisticated tricks and schemes of reactionary objects in order to take measures to fight and oppose is one of the top priority tasks of the current functional forces. The authorities recommend that, in order to avoid falling into the extremely sophisticated “information trap” of hostile forces, each citizen himself needs to stay awake, raise vigilance, properly identify and proactively prevent prevent, fight, prevent, and expose distorting claims of hostile forces. When approaching websites, it is necessary to be vigilant, verify and compare information with official sources, absolutely do not share or comment on articles of unknown source, first of all to protect themselves, then contribute to creating the spiritual strength of the community, firmly defending the ideological foundation of the Party against the plots of “peaceful evolution” by opportunists and reactionaries.

Image of an unidentified flying object Is that a bird? An airplane? Drones? Or something extraterrestrial? The US government has been scrutinizing these unidentified flying objects. A report summarizing what the US knows about “unidentified flying objects” – aka UFOs – is expected to be published in June. However, contrary to many people’s expectations, no “alien” will appear. Two unnamed officials briefed on the report said they had found no information about a UFO connection to extraterrestrials. According to the two officials, the report does not rule out a link between the flying objects and another country. Prior to that, because of concerns about the threat to national security, congressmen pushed for investigation and public reporting of mysterious phenomena that the US government did not want to talk about for generations. At the request of Congress, the Director of National Intelligence is required to submit a consolidated report from multiple agencies within 180 days. This deadline is coming to an end. However, the intelligence office did not specify when the report was released. Republican Senator Marco Rubio (Florida), one of the senators pushing for the investigation, told Fox News : “These are flying in our airspace. We don’t know what it is. We need to find out.” “There are a lot of unanswered questions right now,” Democratic Representative Adam Schiff (California) said NBC . “If other countries have certain devices that we don’t know about, we’d love to find out. Or if there is some other explanation, we would also like to know.” Luis Elizondo, former head of the Pentagon’s Advanced Aerospace Threat Identification Program, said he does not believe the unidentified objects are the technological product of a foreign power, in part. because almost no country can keep this kind of secret. “We live in an incredible universe,” says Elizondo. There are many theories that the three-dimensional universe – where we live – has many things that cannot be explained.” But Michael Shermer, editor of Skeptic magazine, is skeptical. Longtime analyst of UFO theories and other phenomena, says he has seen too many blurry images of alleged encounters with aliens. However, Shermer notes that now several billion people around the world have smartphones that take sharp pictures, and satellites can accurately display every detail on the ground. “90% to 95% of UFOs detected are actually weather balloons, flares, secret military planes, birds reflecting the sun, planes reflecting sunlight, meteors, space junk , satellites, lightning balls, ice crystals reflecting light from clouds, or light reflected in the cockpit windows…” “Show me alien bodies, show me spaceships or show me really high quality videos and photos,” he said in an interview. “That’s how I believe it.” “We need proof rather than noisy videos and blurry photos. Because this would be one of the most unbelievable claims ever, if it proves aliens are real. .” Pilots and skywatchers have long reported sightings of UFOs in US airspace. These UFOs often have unusual speeds or orbits. In 1960, the CIA reported that 6,500 objects had been reported to the US Air Force over the previous 13 years. However, the air force concluded that there was no evidence that these objects were related to “interplanetary spacecraft”. Some people who research the topic say the US government often “restricts mentioning or lying about things that cannot be explained.” However, retired Air Force Colonel Richard Weaver insists that the government does not have the authority and capacity to cover up the encounter with aliens. “Even if it’s hard for us to keep it a secret, how can we build a conspiracy theory like that,” Weaver said. In December 2017, a turning point happened when New York Times revealed the Pentagon has a five-year project to investigate UFOs. The Pentagon later released a video showing military pilots confronting fuzzy objects they could not identify. In 2019, the US Navy announced it would create a formal process for its pilots to report unidentified aerial phenomena, or UAPs. Last August, the US Department of Defense established a task force, tasked with “detecting, analyzing, and cataloging UAPs” that may pose a danger to the United States. In an age of increasingly sophisticated drones, the US military’s theory leans more towards adversary equipment, rather than aliens. However, the creation of the task force is seen as a rare admission from the government that UFOs pose a national security concern.

Humans used to believe that the Earth was the center of the solar system until Nicolaus Copernicus, a Polish astronomer, proved that our Earth is just a planet revolving around the Sun. Later, Newton proved the principle behind the planets orbiting the Sun with the law of universal gravitation. He said the larger the objects, the greater the force of attraction between them, but the further apart they are, the weaker the attraction. Next came Albert Einstein’s theory of relativity, which suggested that all objects in the universe lie on “a cloth”, which is a four-dimensional continuum known as space-time and causes distortion. Massive objects like the Sun warp space-time around them, so Earth’s orbit is simply the result of our planet obeying this curvature, similar to gravity. Newton. Does quantum theory contradict the concept of space-time? Besides, we also have another concept that is quantum theory. In the quantum world, a physical system always has overlapping states. Specifically, a particle can exist in many places or have many velocities at the same time. In the 1930s, physicist Erwin Schrödinger devised a thought experiment that is still known today as “Schrödinger’s cat” to discuss this quantum theory. Suppose there is a sealed box, inside is a living cat with a vial of poison and a radioactive substance that will decay after about an hour (but also probably not). If decay occurs, it will be recorded by the quantum state meter and activate the counter causing the hammer to be dropped to break the vial of poison, which will kill the cat. If the potion hadn’t been broken, the cat was still alive. The problem here is that until the measurement is taken, the cat will be in two superpositions of life and death. Massive objects warp the structure of space and time around them, resulting in neighboring objects following a curve. Photo: Space. This cannot be reconciled with the space-time continuum. “The gravitational field cannot be in two places at once,” said Sabine Hossenfelder, a theoretical physicist at the Frankfurt Institute for Advanced Study. According to Einstein, space-time is warped by matter and energy, but according to quantum physics, matter and energy exist in many states simultaneously. “So where is the gravitational field?” Hossenfelder asked. However, no one has an answer to that question. Looking for a solution To be able to reconcile the two theories, physicists have tried to find a common theory that solves both quantum physics and space-time theory. Perhaps the most famous theory is the string theory of physicist Andrew Strominger. It’s the idea that subatomic particles like electrons and quarks are created from the continuous oscillations of microscopic filaments, not from collections of particles. However, the strings must vibrate in 11 dimensions, while Einstein’s fabric of space-time has only four. “String theory is interesting math, but whether it describes the space-time we live in, we need an experiment to prove it,” said Professor Jorma Louko from the University of Nottingham. know. String theory, a way to reconcile relativity and quantum theory, says that reality is made of vibrating strings. Photo: Spice. Evolving from the limitations of string theory, other physicists have turned to an alternative called Ring Quantum Gravity (LQG). They argue that space-time is made up of a series of interwoven loops structured on the smallest size scales, like a cloth. However, it is made of a network of stitches, or like a computer photo, made of individual pixels. According to physicists studying the LQG, these loops are so small that the number of rings in a cubic centimeter of space is more than the volume of the entire observable universe in cubic centimeters. “If space-time differs only on the Planck scale, this would be difficult to test in any particle accelerator,” says Louko. You’ll need an atom smasher 1,000 trillion times more powerful than the large particle accelerator (LHC) at CERN. To find the answer, scientists must use light from Gamma rays at a distance to look for evidence for LQG. The signals we receive from the universe may have traveled billions of light years, experiencing the influence of space-time. Cosmic flashes are emitted as stars reach the end of their lives, scientists are still trying to understand the meaning of these explosions in space. “Their spectral ranges have systematic distortion,” commented Hossenfelder. However, the problem now is to find the answer to the cause of this distortion. An alternate picture shows that space and time are not smooth, but are instead created by a series of small loops. Photo: Space. Quantum entanglement According to Einstein, space-time always exists even if there are no stars or planets around it. However, physicists Laurent Freidel, Robert Leigh and Djordje Minic argue that space-time does not exist independently of the objects in it. According to them, space-time is defined by the interactions between objects. “This may sound confusing, but it’s the best way to approach the problem,” Mr. Minic said. The theory mentioned above is called the modulus of space-time, which can explain a well-known phenomenon called “quantum entanglement”. Quantum entanglement is when two atomic particles are brought together and linked their quantum properties. Then, when the scientists separated them from each other, they found that the particles retained their property bonds. When the properties of a particle are changed, the particle at the other end will sense this change immediately, faster than the speed of light. Einstein was so confused by this phenomenon that he called it the ‘spooky effect at a distance’, because the speed of light is the fastest, according to him. Modularity of space-time theory can modify the properties of a particle by looking at the “separation” from a different perspective. If space-time emerges from the quantum world, it would be simpler to be closer in the quantum sense than in the physical sense. “Each person will have a different concept depending on the context,” says Minic. It’s like a person-to-person relationship. We can feel closer to our loved ones far away than to strangers around us,” added Hossenfelder. Albert Einstein presented a Newtonian picture of gravity as a force, replacing it with space-time. Photo: Science Photo Library. Freidel, Leigh and Minic have been working on their concept for the past five years and believe they are taking steps towards perfecting it. According to Minic, this would be a novel approach to bring the concept of gravity into the quantum world, instead of quantizing gravity as with the LQG theory. However, any scientific theory needs to be tested. For now, the trio is looking for a way to incorporate time into their model. This new discovery could have a more profound effect on our daily lives. “All of our current devices work solely on quantum theory. If we better understand the quantum structure of space-time, that will have an impact on future technologies – maybe in 200 years,” said Hossenfelder.

Here is a compilation of a few “evidence” that is said to strengthen the belief of those who are passionate about the existence of UFOs and aliens: Unexplained stories about UFOs 1. Captain William Schaffner Incident, North Sea On September 9, 1970, Royal Air Force pilot William Schaffner was flying over the North Sea when he spotted a strange object in front of his plane, hovering over the water in the North Sea. He decided to investigate, but a few minutes later radio contact with Captain Schaffner’s plane was lost. Schaffner’s plane was later found on the seabed. However, the dome was closed and there was no trace of the pilot. No one knows what might have happened to the captain. (Photo: Marca) 2. The incident Tehran, Iran On September 19, 1976, Iranian military forces detected an unidentified flying object in the sky over the capital Tehran. When two Iranian air force jets approached the mysterious object, the pilots lost radio contact with the ground. When preparing to fire at the UFO, their weapon system also failed. Only after leaving the vicinity of the strange ship did they resume full control of their aircraft. 3. The Lights of Rendlesham Forest, England The Rendlesham Forest Incident is the name given to a series of scenes that occurred in 1980 following an alleged landing of an unidentified flying object in Rendlesham Forest. The British Ministry of Defense has never considered this event a threat to national security. Therefore, the incident was never formally investigated. 4. US Navy encounters UFOs The encounter occurred during a combat exercise conducted in the Pacific Ocean off the southern coast of California on November 14, 2004. (Photo: History) Pilots of six F/A-18 Super Hornets reported detecting “something” in mid-air, and on radars of US Navy ships and other fighters in the area also appeared. this flying object”. In 2014-2015, fighter pilots of the USS Theodore Roosevelt aircraft carrier strike force also reported recording sensors that detected unidentified aerial objects. Amazing images of UFOs In 2016, the US Intelligence Agency (CIA) released a number of photos of mysterious flying saucers that had appeared in the past that the agency had never made public before. The UFO photo was recorded by Stock in 1952 in New Jersey, USA. At about 4:30 p.m. on July 29, 1952, Mr. Stock was sitting in his yard with a friend when they saw a strange object appear in the sky. He ran into the house to get a camera and took 5 pictures of this UFO. The mysterious object flew at an altitude of about 60m, then accelerated and disappeared. The flying saucer was then described as possibly made of metal, solid and had a transparent dome-shaped upper part. Stock and friends say that the disc is blue or blue, makes no noise and is about 10 meters wide. The image was taken on October 20, 1960 in Minneapolis, Minnesota, USA Another image released by the CIA is a strange, large, glowing disc, believed to have been taken on October 20, 1960 in Minneapolis, Minnesota, USA. This image has never been confirmed to contain any content, but it is believed to be one of the first examples of so-called “stealth UFOs”, the term referring to flying saucers hiding in the clouds to avoid was discovered. Pentagon admits UFOs In May 2019, the Pentagon admitted it was investigating UFOs after naval pilots claimed to have recorded UFOs during training exercises in 2004 and 2015. The program to investigate and study threats from unidentified flying objects (UFOs) took place from 2008 to 2011 and cost up to 22 million USD of the US Department of Defense. This is the first time the Pentagon has acknowledged the existence of this program. (Photo: Defense) In 2020, the Pentagon officially released three short videos showing UFOs, previously released by a private company. The footage, titled “FLIR1”, “GIMBAL” and “GOFAST” was captured by a camera on a US military jet. The videos show what looks like an unidentified flying object moving very fast under the infrared camera. Two of the videos feature officers marveling at the speed of the unidentified flying object. One of them speculated that the object could be a drone. NASA discovers thousands of exoplanets NASA has confirmed the number of extrasolar planets (exoplanets) in the thousands, and we can expect that number to continue to grow as we improve the technology that spaceflight can travel. into other regions of space. (Photo: Insider) This opens up the meaning: There are thousands of known planets that have not been discovered for a long time; and several other planets waiting to be discovered that could be in potentially habitable environments. Existence of the Search Institute for Extraterrestrial Intelligence (SETI) The Search for Extraterrestrial Intelligence (SETI) Institute was founded by Carl Sagan and Jill Tarter, two American astronomers who believe there is more interplanetary life than we thought. (Photo: SETI Institute) SETI’s mission is to “discover, understand and explain the origin and nature of life in the universe, the evolution of intelligence.” The institute’s brilliant minds are working day and night to find ways to trace it. life and aliens in outer space. Another scientific organization searching for intelligent life in the universe actually exists on Earth. It’s proof of how seriously humans care about “aliens”.

People wait to be vaccinated against COVID-19 in Tokyo, Japan on May 24, 2021. Photo: AFP/VNA According to the Vietnam News Agency correspondent in Tokyo, speaking at a press conference after announcing the extension of the state of emergency for nine provinces on May 28, Prime Minister Suga Yoshihide emphasized his determination to deploy COVID-19 vaccine vaccination for people under 65 years of age, including those with underlying medical conditions, starting at the end of next month. Regarding vaccine supply, Prime Minister Suga affirmed that the government will ensure the necessary amount of vaccine for the vaccination campaign with 100 million doses expected to arrive in Japan by the end of June and another 100 million doses to be added. September. The specific vaccination time of each locality will be decided on the basis of the positive results of vaccination for people over 65 years old, and the location can also be expanded to implement in the workplace. jobs or universities. Prime Minister Suga said the Japanese government will do its best to soon return to normal life for the people with efforts to speed up the pace of COVID-19 vaccination. Currently, the vaccination rate is around 400,000-500,000 times/day, but from June it will be increased to 1 million times/day. Japan started the COVID-19 vaccine vaccination campaign in February, basically giving enough shots for medical staff who are the frontline force against the epidemic. With the operation of two large-scale vaccination centers in Tokyo and Osaka from May 24, as well as positive results from the negotiation to buy vaccines, the Japanese government is expected to be able to vaccinate the entire population. the entire population from the end of June, 1 month earlier than originally planned. In addition, children will also be included in vaccination after the Japanese Ministry of Health, Labor and Welfare (MHLW) has licensed Pfizer’s vaccine to expand the vaccination age from 12-15 years old. . Meanwhile, the pharmaceutical company Modena has also submitted clinical data to the MHLW and may be approved for injections in subjects 12 years of age and older next month.

Nathan Copeland controls a robotic arm using electrodes implanted in his brain. Published in the journal Science, the team say their work demonstrates that adding sensation to the technology significantly improves the function of prostheses for quadriplegics, compared with based solely on visual cues. Nathan Copeland, 34, told AFP: “I am the first person in the world to have a device implanted in the sensory cortex that scientists can use to stimulate my brain directly. And then, I felt like I had a real feel in my flesh and blood hand.” In 2004, Copeland was involved in a car accident that left him with a severe spinal cord injury and quadriplegia. He volunteered for scientific research and six years ago he underwent major surgery to implant tiny electrodes in his brain. Two sets of 88 electrodes the width of a human hair are arranged like tiny combs and penetrate deep into the cortex, which controls motor function. According to Associate Professor Rob Gaunt of the Department of Physical Medicine and Rehabilitation at the University of Pittsburgh, co-leader of the study, fewer than 30 people in the world have received such a transplant. What’s unique about Copeland’s case is that an additional set of electrodes is connected to his dorsal cortex, which receives and processes sensations. The idea of ​​sending haptic feedback to the tactile sensory cortex dates back decades, but doing so in a controlled and understandable way by brain circuitry used to be a major challenge. After Copeland underwent surgery to install the electrodes, the team was truly thrilled. Then came the decisive moment, when they tried sending the first tactile signal. “It felt really fuzzy,” Copeland recalls. He asked them to try again to make sure it was real. Before the interface could work with the robotic arm, the scientists had to perform a series of tests on Copeland. First, they needed to learn which electrodes cause what sensation when activated and which fingers are associated with them in order to set up the robotic hand correctly. They also made him watch a video of the robotic arm moving left or right and recorded the electrodes lighting up when he was asked to “think” it was him controlling it. Copeland sat next to a black metal robotic arm and was asked to pick up a series of small objects such as rocks and spheres and place them in a box – when the tactile sensors were turned on or off. He can complete each task in an average of twice as fast when the sensors are activated, and can even perform more complex tasks like picking up a glass and pouring its contents into a glass. another cup. The team wanted to further refine the prosthetics because they didn’t want to just do science experiments in the lab, but wanted to actually make devices that would be useful to people. Copeland has set up his brain-computer interface at home when the Covid-19 pandemic shut down universities and has used his downtime to learn how to draw on a tablet and even play video games. death. He does this by using his mind to send signals directly to the computer, instead of using his arms to press buttons.

Customize sharpness parameters on smart TVs. Photo: Lifewire However, the reality is not so, on most smart TVs today, the Sharpness feature only has the effect of “edge enhancement” (simply speaking, expanding the border), and this can reduce some small details on the picture. That’s why you should reduce the Sharpness parameter to less than 20% or less (possibly 0). On the left is the original image, and on the right is the Sharpness enhanced image. It’s not hard to notice that the image on the right has some extra halos around the subjects, which is what the Sharpness feature brings. Normal image and Sharpness boosted image. Photo: CNET This basically makes objects easier to see, but they also make other areas grainy. In fact, the image that has not been sharpened will be softer, helping you to see small textures on the walls, facial pores, etc. Note, if you are using a 4K TV, users will not be able to receive it. See the difference when increasing and decreasing the Sharpness parameter. In short, to get the best visual experience when watching TV, the easiest way is to switch to Movie mode, or you can tweak the Sharpness parameter to 0-20%.

The birth of flying saucers It was not until 2015 that this investigation was made public. To date, some of the strangest UFO incidents have been posted online, revealing mysterious objects in the sky that have shocked those who have witnessed it. The most famous case is the “Lubbock Beam” incident that 3 professors in Texas reflected on August 30, 1951. Together, they claim to have seen 20-30 lights in the sky. The objects appear to be about the size of a saucer and have a green fluorescence. “They are smaller than the full moon on the horizon. About 15 such bright streaks, round … We all feel extremely strange “- a professor shared. However, the USAF concluded that the light appeared to be caused by a porcupine (whose breast feathers are white, possibly reflecting light from urban lights below). Of the more than 12,000 UFO cases presented for dissection in the Blue Book Project, the majority concluded “disappointment” as such. The USAF believes that most of the strange objects seen are stars, clouds, civilian aircraft or reconnaissance aircraft. However, 701 of them are still unexplained. New Zealand UFO photo titled “Winter 1951”. Many believe it to be a flying saucer, but the USAF thinks it’s just a lenticular cloud Photo: DAILY MAIL Evaluating the aforementioned massive investigation, Nigel Watson – author of the “UFO investigations Manual” (about UFO investigations from 1892 to the present) – said that in many cases, amateur investigators trying to find an explanation without having time to consider or research. In particular, a particular case that attracted Mr. Watson was the reflection of Kenneth Arnold’s strange object, an incident that can be called the beginning of the extremely popular term “flying saucer” later. Mr. Arnold saw 9 UFOs on Mount Rainier (Washington State) on June 24, 1947. The US government agencies were particularly interested in this report. A similar scene appeared in Tulsa, Oklahoma just a month later, on July 12, 1947. “These objects fly in a diagonal line stretching about 8 km, from the first object to the last object, evaporating,” said Mr. Watson. According to Arnold’s estimation, the above objects were traveling at more than 1,600 km/h from Mount Rainier to Mount Adams. It is “like a saucer if you let it slide across the water”. Soviet secret program Mr. Watson believes that the term flying saucer was born from describing the motion of a flying object rather than its appearance. From secret aircraft to simply birds flying in the sky have been proposed to try to explain the strange phenomena that are reflected, but, in fact, they are still a mystery. In the 1940s and 1950s, the events of encountering flying saucers or even alien abductions in the United States, began to fill the newspapers of this country. However, according to Soviet ufologist and author Paul Stonehill, UFO encounters on the Soviet side at that time were far more direct than those of the US and any object flying over the Soviet Union would have attracted the attention of the military. “The Soviets were shocked that so many UFOs were able to penetrate their borders and unleash themselves without the Kremlin knowing how to control,” Mr. Stonehill revealed on the Daily Star website. During the Cold War and the space race, Soviet forces frequently clashed with UFOs, once they were ordered to shoot down UFOs but failed. Mr. Stonehill – whose research articles on UFOs have been translated into 11 languages ​​- said that when reports of strange phenomena appear in the press, the Kremlin often interprets them as hoaxes. of the Western powers. However, a secret research program called SETKA (Iron Grid) was established in 1977 at the behest of then-President of the Council of Ministers of the USSR Alexei Kosygin, after the famous Petrozavodsk affair, during 48 UFOs appeared in the sky over the city in this Republic of Karelia (then in the Soviet Union). The purpose of SETKA is to identify UFOs as authorities have begun to acknowledge these flying objects may not belong to Earth. According to Mr. Stonehill, most of the files of this sensitive program remain secret. In total, more than 400 unusual mysterious cases, encounters with UFOs or aliens, were studied. The show also changed its name several times to distract the curious. Fierce encounter Through conversations with military intelligence personnel, government officials and Soviet-era scientists, Mr. Stonehill said the most intense encounter between UFOs and Soviet forces occurred in 1953, shortly after leader Joseph Stalin died. A large UFO appeared in the sky over the Taiga region in Siberia. At first, eyewitnesses thought it was a balloon. Soviet military commanders at that time sent a detachment to the scene. However, when trying to attack the foreign object, 3 of the detachment’s planes caught fire. Later, throughout the 1960s, Soviet forces had to comply with a limited order to shoot UFOs because authorities believed that the objects would fight back and destroy any unit that fired. into them. However, in some cases, the UFO side made the move first! In 1990, the legendary Soviet test pilot Marina Popovich held a press conference at the Russian Consulate in San Francisco and published images of what she called an alien plane. The female pilot with the rank of colonel claimed to have seen photos of children of human-alien hybrids. At the same time, Ms. Popovich said that Russian cosmonauts have also encountered UFOs many times.

Although there is not enough evidence to conclude whether these flying objects are from another planet, some videos and images of UFOs have been confirmed by the US military to be real. This information not only interests the community interested in extraterrestrial life, but also raises questions about the information the Pentagon holds about UFOs. The US has repeatedly recorded reports of mysterious flying objects appearing in military airspace. (Photo: CNN) Next June, the office of the director of the National Intelligence Service and other agencies are expected to submit previously unpublished UFO reports to the US Congress. According to CNN’s source, the US will soon announce how the Pentagon handles information about unidentified flying object encounters. What are UFOs? UFO is a flying object whose shape and movement are completely different from all types of aircraft that man-made. Many theories suggest that they are technological products from extraterrestrials, but so far the true nature of UFOs remains a mystery. Last month, the Pentagon officially confirmed that some images and videos recorded by the US Navy were genuine. In 2017, a former US Navy pilot claimed to have seen an unidentified flying object in 2004. This person said the object believed to be a UFO had a very strange way of moving. “ When I got close, it quickly accelerated south and disappeared in less than 2 seconds “, said retired pilot David Fravor. Video taken by US Navy soldiers in 2019 shows flashing triangular objects moving through clouds. Several other images also provided by the Navy show three spherical metal-like objects flying in the sky. In April 2020, the Pentagon released three videos from infrared cameras showing flying objects moving at very fast speeds in the air. According to Pentagon spokesman Sue Gough, the Navy acknowledged the veracity of the videos released in 2019 months before they were released “to clear up public doubt as to whether the videos were released in 2019. Is it real or not?” UFO is a flying object whose shape and movement are completely different from all types of aircraft that man-made. (Photo: The New Yorker) Are aliens real? The US government’s recognition of UFOs as real leads to the question: Are aliens real? Luis Elizondo, former director of the Department of Defense (DoD) research program, once said: “ There is compelling evidence that we may not be alone (in the universe). “. “ These planes – we call them airplanes for now – have features that cannot be found in American equipment or in any foreign technology that we know of. “, said Mr. Elizondo. But whether UFOs are alien vehicles or a human product, they are still of interest to the US government. Because the problem of handling unidentified flying object information is also related to ensuring that all potential risks to the national security of the United States are taken seriously. Whether that threat comes from space or not. “ Whether it’s weather balloons, green aliens or something else – we can’t ask our pilots to put their lives unnecessarily at risk. “. Rachel Cohen, spokeswoman for Democratic Senator of Virginia Mark Warner, speaking about UFOs in 2019. UFOs have features that cannot be found in American equipment or in any foreign technology. (Photo: CBS News) What’s in the new UFO report? While UFO experts applaud the recent moves by the US government, many remain skeptical of the content of the upcoming unidentified flying object reports. This suspicion stems from the Pentagon’s indifference to previous UFO reports. Many times, the community interested in this issue received only the vague answer that the appearance of flying objects was “unexplainable”. Therefore, they believe that the new report will not provide complete and comprehensive information about UFOs. Last month, Mr. Elizondo said that the “best case scenario” is that the new report only outlines the issue and offers the promise of “another, more detailed report” in the future. “ Unfortunately, what we don’t know outweighs what we do know. But the good news is that we’re finally getting serious about it “, said Mr. Elizondo. The Pentagon has set up a panel to explore the “nature and origin of unidentified flying objects”. (Image: Getty Images) The Pentagon says it has conducted research on audio recordings of unidentified flying object encounters as part of a secret program deployed at the request of a former Democratic senator. owner Harry Reid in Nevada. The program began in 2007 and ended in 2012 as the US Department of Defense assessed that funding for more important projects should be prioritized. Following the program, the Pentagon established a topic to explore “the nature and origin of unidentified flying objects” by 2020, according to the US Department of Defense. Topics include videos of UFOs recognized last month. Up to now, the truth about UFOs, or the question of whether or not aliens exist, remains a secret from the public.

iRobot S9+. S9+ is the most advanced robot vacuum cleaner from the American brand of robot vacuum cleaners – iRobot. The product comes with a dock that automatically collects garbage in the body. Users therefore only need to empty trash and dust from the dock instead of having to clean the drawer on the robot as often as with conventional products. The product uses the AllergenLock technology trash bag designed specifically for the S9+ to filter allergens such as pollen and mold. Half square and half circle machine, dual omnidirectional brush set, technology that is exclusive to iRobot, recently appeared on Ecovacs T9 AIVI series. Most of the latest technology on robot vacuums is available on the S9+, such as redrawing diagrams with a laser sensor using the vSLAM algorithm; identify obstacles, objects that cause obstacles, entanglement in the course of running; control via smartphone and map selection. Ecovacs Deebot T9 AIVI (13.5 million VND) T9 AIVI is Ecovac’s first robot line to integrate the Aeroforce dual-action rubber brush system shared from iRobot. As a result, the product has a higher suction efficiency, even with large garbage objects or stains sticking to the floor surface. This is also the top model with high suction power today, 3,000 PA, 300 ml garbage box capacity, 240 ml water box for cleaning, 5,200 mAh battery capacity. Compared with high-end robot lines, T9 AIVI has the most significant advantage of a vibrating cleaning system and an electric water regulating valve. The software on the machine also allows storing many different maps, suitable for multi-storey houses. Roborock S7 (12 million VND) Roborock S7. S6 Max proved “short of breath” compared to products from Ecovacs, Roborock has launched S7 with many technologies no less than the competition. The most significant upgrade is the Sonic Mopping water damper vibration mopping system that can vibrate 3,000 times per minute. The new wiping mechanism is significantly more effective than the old S6 Max series. However, the suction power of the machine is only kept at 2,500 PA and there is no dual rubber brush system like iRobot or Ecovacs. The S7 has a camera system that detects objects such as wires, socks, and baby items so that the device does not get entangled or entangled when operating. This camera can also be viewed directly from the phone. Neato Bootvac D7 (19 million VND) Neato Bootvac D7. Bootvac D7 from Neato has many similarities with iRobot S9+ in terms of half square, half round design. The company explains that this design helps to limit the omission of dirt in the corner. This is also a recognizable difference with most of the remaining robot models on the capital market, which are circular in shape. The machine also has a navigation system, laser map redraw, save multiple maps and select a cleaning area. Largest trash can capacity in the segment – 700 ml. However, the suction power of the machine is poor compared to competitors at 1,600 PA. Without the dual rubber brooms like Ecovacs or iRobot, the D7 has a broom that’s almost twice as long. The machine can also be controlled remotely via the application, schedule cleaning, create virtual walls …

Shadows are just random things you see on the road made by objects, however, if you have a chance to visit Redwood City, California, you will be amazed to realize that the shadow does not match. with shadow objects. Living in California, USA, Damon Belanger is an artist known for his diverse artworks. His recent project impresses with shading drawings of very ordinary objects that give a new picture to the street. The series of paintings is quite cheerful and humorous, at first glance everyone thinks it is just an ordinary object, but when you look closely, you will see many differences. Anyone who happens to come across a piece of shading art will feel confused and have to look back a second time to spot the difference. Damon Belanger has filled the streets of downtown Redwood, California, USA with his interesting works of art. The whole city seems to turn into a wonderland attracting tourists. Artist Damon Belanger was inspired by simple things like bicycle racks, benches, trash cans, etc., inanimate objects that can appear on any street. Damon created these beautiful shading artworks and breathed new life into many lifeless streets. That’s when the artist transforms the mailbox into a cartoonish, smiling monster, the city map into a robot, the road markers into flowers… To begin the process of creating a unique piece, Damon selects the object he wants to shade and then sketches a character or painting using chalk. The artist cleverly chooses the angle to place the work so that it resembles the shadow as much as possible. Damon’s pictures are playful and humorous. After painting, Damon will paint over it with gray paint to make the picture last longer. Damon hopes that he can bring this project to larger cities across the United States to bring joy to everyone. Damon’s artworks are proof that a very creative artist can turn any public place into his ‘playground’.

Feng shui expert Phung Phuong warns that in the house there are 4 things that must be more precious than gold, do not be foolish to give it to anyone lest you bring fortune to your hand. Used wallets Even if the wallet is still healthy and no longer used, you should not give it to others. This is a feng shui object that symbolizes money, giving it is like giving your fortune to others. User idols Many people think that bringing the God of Wealth to friends on the day of opening or opening a business will make them prosper, trade and sell expensive, money comes in like water. That concept is not wrong, but it means that you will lose all fortune in your house. Moreover, the God of Wealth statue is only fulfilled when the owner himself sincerely requests it, so when he opens it, he will bless the client with good luck and fortune. Aquarium Some people, after receiving the gift of a fish tank, felt that fortune was not favorable, so they invited a feng shui expert to see. It turned out that they didn’t know that fish tanks like “Gods of Fortune” could not be given as gifts. There are some people who are hydrophobic or afraid of fish farming, so giving an aquarium is no different from harming the person receiving the gift. The location of the fish tank is also very important, requiring the guidance of a feng shui expert. Sharp thing Sharp objects such as knives, swords, scissors … according to feng shui will bring bad points, cut off good relationships or bring dangers to the recipient. If you want to give a beautiful and valuable knife or scissors as a unique souvenir, you should tell the recipient in advance. Then ask them to give you change or small coin, as if they paid for the item themselves. This is a folk trick to avoid the bad luck of the gift. Sharp objects should only be given as souvenirs, used as souvenirs for birthdays, birthdays or weddings. In addition to the above 4 objects, there are many other great taboo objects according to folk beliefs that should not be given or given to others. Because even if your property is good, your mind is impartial, but it is not by chance that grandparents draw it like that, so having taboo is still better than you! * Information is for reference only

Exploring the stars is man’s way to the universe. Some people think that each star represents a destiny, others say that the stars are small angels tasked with lighting up the night. Today, science has been able to give us a more precise answer. What is a star? Stars are all celestial bodies that are capable of emitting their own light. All of them are giant air spheres. They are tens to hundreds of thousands of times more massive than Earth. Only thanks to such a large mass can they create their own light. An object to be able to emit its own light needs to have a mass of at least 70 times the mass of Jupiter – the largest planet in the Solar System, that is, about 7% of the mass of the Sun. Why do we see the stars? The stars in the sky have always been a mystery to the human imagination. Our Earth has a mass of about 6x1024kg (6 million billion billion tons). The Sun is 330,000 times heavier than the Earth. That is, a star with a mass of 7% of the mass of the Sun would be about 23,000 times heavier than the Earth. Every object has a gravitational force that directs the center of it to its heart. Normally no one notices but we ourselves are always attracted to our own. Because each part of the body is attracted to each other and the sum of them all form a gravitational force directed towards a center of mass in our body (the center of gravity of the object). The table, the chair, the Earth, are always gravitating to itself by a force called centripetal gravity. But why doesn’t it all burn brightly? That’s because the mass of the objects we come into contact with every day just can’t afford that. Because gravity is a force proportional to mass, gravity in everyday objects is so small that they don’t cause any significant effects. With very large objects such as planets, Earth, gravity is also negligible because it creates a clear attraction that pulls everything towards it. For example, when you jump high, you will fall very quickly because of the pull from the Earth. As for the aforementioned massive objects (tens of thousands of times heavier than the Earth), the great gravity makes the pressure at the center of the celestial body very high, this pressure provides a great acceleration for the celestial bodies. gaseous atoms (mostly hydrogen). They collide strongly with each other at high velocities, breaking the electron shells, separating electrons from the atomic nucleus. At the core of the star is no longer ordinary gas but a state of chaotically moving nuclei and electrons. This state is called plasma. In the plasma state, the hydrogen nuclei have a chance to collide directly with each other at high velocities, which causes what we call fusion reactions, fusing hydrogen nuclei into heavy hydrogen and finally is the helium nucleus. This reaction is known on Earth in hydrogen bombs – bombs capable of releasing thousands of times more energy than atomic bombs of the same mass. The fusion reaction at the core of a star releases a lot of energy in the form of radiation, some of which is visible light. This radiation is transferred to the star’s surface and causes the star to glow. Stars are composed mainly of hydrogen (over 70%), with a large part helium remaining, and an insignificant fraction of heavier gases. The surface temperature of a star is usually in the range of 3,000 to 50,000K, and the temperature at the center is in the range of several million to several tens of millions of K. It can be as high as 100 million K for red giants and several billion K. with red supergiant stars. Star classification Graphic image. By mass, stars are divided into two types, dwarfs and giants. Today, modern division is based on spectral charts. In which, the star with the obtained spectrum of which position on the chart will be determined to belong to which group with specific characteristics of mass and temperature. The most widely used spectrogram today is the Hertzsprung-Russell chart. This graph represents the luminosity, size, and temperature of any star when its spectrum is obtained. According to temperature, the chart is divided into 7 levels with the symbols O, B, A, F, G, K, M respectively. In which, the star closer to O is hotter and closer to M is cold. Each level itself is divided into several sub-levels. Through the chart, it can be seen that most of the stars in the universe are concentrated in the main sequence of the chart. This sequence is a sequence of dwarfs and subgiant stars. Our sun is also on this sequence. It is located in the G group, has the detailed spectral designation G2V (yellow dwarf/Yellow dwarf). Below the sequence are groups of white dwarfs, and above are giants and supergiant, supergiant stars. Star evolution All stars form from large clouds of dust and gas called protostar nebulae. Due to gravity they gather together and shrink until they form a dense mass. As we all know, all objects that carry mass carry gravity. The same object itself also has a force of attraction between different parts of it. However, the gravitational force between small masses is negligible and we hardly notice it. Only significant forces, such as Earth’s gravity acting on people and objects, are enough to be noticed. In stars, gravity is very strong (due to its high mass). When the force of gravity is too great for the atoms to bear, they break the atomic shells and accelerate their nuclei. Hydrogen nuclei (consisting of 1 proton) when collided at high velocity, combine to form heavy hydrogen, and then helium. This reaction releases energy that causes the star to burn brightly. This is a fusion reaction (also known as a nuclear explosion. This reaction is used in the hydrogen bomb (H bomb) – the most destructive destructive weapon that mankind has built). Thanks to the great energy released from nuclear fusion in the star’s core, the gravitational contraction is halted as the released energy balances the gravitational force. The star burns so brightly for several tens, hundreds of millions or billions of years. The lower the mass of the stars, the longer the lifespan. For example, our Sun is a dwarf, medium mass, it can live for about 10 billion years. Meanwhile, stars are much larger, sometimes only living a few hundred or even tens of millions of years because the high mass creates greater pressure towards the center. It causes nuclear fusion to happen faster and the star to deplete energy faster. After burning out all of its hydrogen energy, the star no longer produces energy against centripetal gravity. It will once again shrink. At this time, the helium nuclei combine to form nuclei of heavier elements such as carbon, oxygen and heavier elements up to iron. This process releases an energy that inflates the star’s crust while the star’s core continues to contract. This is the red giant stage. For medium-sized stars (with a mass between 0.5 and 10 times the mass of the Sun), the red giant shell, when inflated sufficiently large, will explode and break up to form a planetary nebula. Meanwhile, high-mass stars have massively inflated stellar shells, becoming red supergiant stars. During this stage, the stellar core continues to contract due to gravity, temperature and pressure both increase many times compared to the previous stage, allowing nuclei of heavier elements to be synthesized (from familiar metals). from copper, silver, and gold to radioactive elements). Up to a certain limit, the energy released from the core creates a large explosion that breaks the outer shell. This is a supervova explosion. After the shell is broken, the star’s core remains for both massive stars as well as light stars. For low- and medium-mass stars like the Sun, the core will stop shrinking, becoming a white dwarf, emitting a very faint light. After billions or tens of billions of years, the generation of radiation ends, stars no longer emit light. It’s called a black dwarf, a dark, dead mass of matter. In fact, the process for a white dwarf to become a black dwarf is so long that so far a black dwarf is only a theoretical prediction. No white dwarf in the universe has been around long enough to become a black dwarf. For massive stars whose core remains after the supervova are at least 1.4 times more massive than the Sun, the mass is so great that they continue to shrink. The nuclei react with each other to form heavy nuclei. The contractions are not over yet, they cause the free electrons to be squeezed tightly against the protons, combining to form neutrons. The star becomes a solid mass of matter, composed entirely of neutrons. Therefore, it has extremely high density and extremely fast rotation speed. This object is called a neutron star. Previously, when this object was first observed, astronomers saw that it emitted a very strong amount of electromagnetic pulses, so they called them pulsars. Even more massive stars with a core mass at least 2 or 3 times that of the Sun, have not stopped after reaching the neutron star stage. They squeeze all matter together to an infinitely large density, concentrated at a location called a singularity. This singularity warps the space around it, a region of space that is bent to an infinite (closed) curvature. The boundary of this space is called the event horizon. Because the space is bent inward, anything that goes in can’t get out, not even light. This entire region of space bounded by the event horizon is called a black hole.

3 light streaks in the sky were recorded by people The British Daily Star newspaper quoted information from the Bolivian media about the incident that happened in the city of Santa Cruz with the central part of this country: “after three light streaks appeared in the sky, aliens were seen. leaving the UFO and walking on the street spooked children and young people”. Traces of UFOs left on the lawn According to the article, this alien is about 30 cm tall, has a round head and very large eyes. The hand has only three fingers, looks like the chupacabra (goat blood-sucking demon) in American legend. Someone previously said that they had seen chupacabra appear in Puerto Rico in 1995. The legendary chupacabra goat sucker The article mentioned that: after this alien creature completed a round and returned to the UFO, it flew to an unknown place, leaving only a circular track on the grass. The local television station reported on the incident as well as interviewed witnesses present. Someone has tried to draw the appearance of aliens and can see the creatures have round heads with large eyes. From people’s sketches, the aliens look like this UFO researcher Javier Aliaga told local media: “When this flying object appeared in the sky, there was an explosion resembling thunder. Also, the object appeared to be breathing fire.” . Santa Cruz seems to be a hot spot for aliens to visit. This is not the first time something like this has happened in the area. In 2016, people in Santa Cruz said they witnessed a mysterious creature come down from a UFO, then walked around and climbed a tree. But when the people here ran out because they heard a very loud sound and saw a flash of light, the alien immediately returned to the UFO and disappeared. Sightings of unidentified flying objects have been reported from many parts of the world. Even the US Department of Defense has confirmed that the US Navy also has a video recording the appearance of UFOs. The video below captures three triangular objects believed to be UFOs, hovering above the US Navy destroyer USS Russell in July 2019 off the coast of San Diego. According to reports, the object hovered about 213 meters from the stern of the Russell. The sailors claimed that they harassed at least three US warships, continuously stalked and engaged in “brazen actions” for 90 minutes while the ships exercised at sea. Susan Gough, a spokeswoman for the US Department of Defense, said: “I can confirm that the UFO images and videos taken by the US Navy are genuine.” Former President Donald Trump, before leaving the White House, also asked the director of national intelligence to report details about “Unidentified Aerial Phenomena” or “Anomalous Flying Vehicles” and expected announced this June. These documents, once published, will spark a global debate about the existence of “Unidentified Flying Objects” (UFOs). Speaking to Fox News, Mr. John Ratcliffe – Mr. Trump’s former director of national intelligence – alluded to the report that, “there is a lot more that is seen about UFOs than what has been made public”. “When we talk about sightings, we are talking about objects that have been seen by naval or air force pilots, or that have been collected by satellite imagery,” he revealed. ”. The former director of national intelligence described them as actions that are difficult to explain, movements that are difficult to reproduce because humans do not have enough technology or moves at supersonic speeds without causing an explosion. supersonic. Mr. Ratcliffe also shared that UFOs and other phenomena have been seen “all over the world” and sensors are picking up these unexplained but not yet publicly available phenomena.

The beauty of Thien Tri Lake. A place with charming scenery Thien Tri Lake in Chinese transliteration is Tian Chi (Lake of Heaven). This is a lake formed by a volcanic eruption around 969 BC, located in a caldera at the top of the Changbai Mountains. There are many legends surrounding the lake, many people believe that the lake is inhabited by the Thien Tri Water Monster. Located at an altitude of 1,907m above sea level and an area of ​​4.9 square kilometers, 105m deep, Tianchi Lake is located about 30km from the Chinese city of Fukang, 45km east of Ürümqi in North Korea. Located in a favorable location adjacent to many places, tourism here is very developed. It is known that with reserves of more than 2 billion tons of fresh water, Thien Tri Lake is enough to supply water for all people in Beijing for 22 months. Due to its high altitude, the lake water is cold all year round, from mid-October to mid-June every year the lake is frozen 1m thick. In the summer, the temperature is also at 8 to 10 degrees Celsius, the oxygen concentration in the water is assessed by experts as low, the soil is arid, the vegetation is sparse, so there are no aquatic animals. reside. Only traveling to China can you see Thien Tri Lake with your own eyes, a place likened to a fairyland. Thien Tri Lake is known as the emerald at the foot of Thien Son range because of its beautiful turquoise water. The space around the lake is harmoniously adorned by immense mountains and forests with green botanicals and conifers. Surrounding the lake are dark green spruce trees mixed with snow mountains silhouetted on the lake surface, creating a magical shimmering beauty. There are four distinct seasons here, the scenery changes constantly over time. The beauty of the lake has unique features in all 4 seasons. Spring is full of life, summer is fresh, autumn is surprisingly peaceful, winter is white, cold but charming. The water in the lake due to melting ice and snow should be cool and transparent. The most beautiful season here is summer because this time is not too cold, the ice melts, the trees are lush and green, the flowers are blooming, making the painting even more beautiful. “Monsters” in Thien Tri Lake Thien Tri Lake also has many mysterious legends. According to a North Korean statement, leader Kim Jong-il was born in the area of ​​Changbai Mountain. By the time he died, the Korean Central News Agency (KCNA) reported that fierce snowstorms had arisen, the ice on the lake surface was broken. When the blizzard dissipated, bright inscriptions carved on the mountain rock that read “Mount Paektu, the sacred mountain of the revolution. Kim Jong-il”, are said to be visible throughout the day, until sunset. Besides, there is also a mysterious story about the “water monster” living in Thien Tri Lake. Accordingly, local people said that the Thien Tri lake monster appeared in 1903, very much like a giant buffalo that emerged from the water, roared to attack three people on the lake and then disappeared after being shot 6 times. stomach. Information about the Thien Tri lake monster appeared again in August 1962, when a witness observed through a telescope that two large creatures appeared to be playing and chasing each other. This story has created a wave of rumors with more than 100 people claiming to have seen the monster with various descriptions ranging from a giant fish to a long-necked fish, resembling a Plesiosaur – a sea monster. Long necks dominated the Jurassic ocean. It is also said that the monster has a head as big as a human head, two very large round eyes, a protruding mouth, and a neck length of 1.2 – 1.5m. The photo is said to capture the horror monster on Thien Tri Lake. On October 9, 1980, China’s “Quang Minh Daily” published a story of a person who had witnessed the “monster” of Thien Tri Lake. The author of an article entitled “Recalling a time when he saw a “monster” said that around 4 am on August 21, 1980, while standing on a high cliff by Thien Tri Lake to watch the sun rise, he discovered In the distance there is an object, body like a buffalo, head as big as a jar, moving very fast, creating a long shelf of water behind. What makes people confused is that Thien Chi Lake is located near the highest peak in the northeast of the Changbai Mountains, formed on the mouth of an extinct volcano, the water is very cold (winter covered with snow and ice, summer at noon). here is also only about 11 degrees Celsius), the nutrient content in the water is extremely low, basically, it is difficult for any kind of organism to live. The results of a survey also show that Thien Tri Lake has no vertebrates. Therefore, the story of Thien Tri Lake suddenly appearing a large animal caused a great shock. On August 23, 2003, a group of tourists including more than 40 people were playing at Thien Tri Lake. It was around 11am, when suddenly, someone shouted, “Look, the beast has appeared again.” All eyes turned to the direction the visitor pointed. In the clear blue water, a black creature, about 3 meters long, was swimming from the south bank to the north bank and then dived and disappeared. Nearly a month before, about 20 “monsters” of Thien Tri Lake made a parade lasting about 50 minutes. Two years later, on 7/7, a person named Trinh Truong Xuan (residing in Phu Tung district, Jilin province, China) while walking around Thien Tri Lake, he happened to notice a shadow floating on the lake surface. Strange black immediately took the camera. Although some people think that it is just a driftwood, Mr. Trinh claims to have captured a picture of a strange creature in Thien Tri Lake. While everyone was still arguing, on July 21, 2005, the “monster” reappeared on the north bank and broke the calm water of Thien Tri Lake more than 10 days later. According to Mr. Hoang Tuong Dong, one person had the opportunity to see the “monster” of Thien Tri lake with their own eyes, the head and neck of the “water monster” protruding above the water surface was over 2 meters high. In 2013, a number of rather poor quality photos were circulated on social networks that are believed to be of the monster at Thien Tri Lake, once again raising attention to the existence of this creature. As recently as October 2020, an employee of Thien Son Thien Tri National Park (China) said that he had captured an image of a round black object floating on the water and thought it was ” Monster Lake Thien Tri”. An employee of Thien Son Thien Tri National Park told the Daily Mail that he spotted “a large creature, about 2.1 meters in size” while on patrol. He saw an unusual object in the middle of the lake and recorded it and posted it on Chinese social media. The footage, shot from an observatory 500 meters above the lake’s surface, shows the black circular object in the water. The black spot looks small on the video but it’s actually quite large in real life, the employee said. This staff member insisted it was definitely not a boat. Up to now, there are still many controversies surrounding the story “Tian Tri Lake Monster”. Many people believe that the “Monster” of Thien Tri Lake is the product of a mutation like in fantasy movies: An ordinary animal, after being affected by chemical radiation, became a giant, carrying monstrous form, even becoming a demon that endangers humanity? But many others found that this is a product of the statue, made up to attract tourists here. So far, there is no explanation or explanation to prove this, the truth about the giant “monster” in Thien Tri Lake is still a place to stimulate the curiosity of tourists when traveling to. China. In North Korea, the lake belongs to Ryanggang province (Luong Giang). Thien Tri Lake has for a decade now become a destination for Chinese tourists curious about the mysterious pair of “monsters” in the lake bed.

MIT has developed a new light-sensitive paint that makes it possible to quickly and easily change colors and textures. Moreover, this type of paint is not expensive. The gecko statue changes color thanks to paint researched by MIT. Photo: MIT. Called ChromoUpdate, MIT’s paint is applied to any product. This paint color is usually quite clean. But when placed under specific frequencies of light, it reveals the underlying pigments. Under UV light, the paint turns black. Within 60 seconds, UV can create gray-toned textures on painted surfaces, anything from printed text to hilly landscapes in high-resolution detail. These patterns continue to remain on the surface after the UV irradiation is stopped. In addition to the gray tone, MIT’s paint has a number of other colors such as CMY color group (green, magenta and yellow). These colors can be mixed together to create a paint that shows all 3 colors at once. To display colors, the researchers shined RGB (red, green, blue) light on the paint, converting the paint to colors that resemble the rays of the light falling on them. This process takes a period of 10 minutes or so for the vignettes to display the correct colors. According to Mr. Michael Wessely, postdoctoral fellow and project research leader, the use of color-changing paint has many benefits. Designers can check products quickly and change colors or textures in minutes. Place the UV projector close to the visible light projector and swivel base to support the object. Photo: MIT. From a broader perspective, Mr. Wessely imagines quickly projecting data onto everyday objects making smarthome systems “smarter” without the need for additional screens in the home. His team has proven they can print text and images right on a cup. For example, you can print a schedule on a cup of water or a reminder on a coffee cup to know when the next meeting is. Besides, people can refurbish their iPhone cases at any time. Instead of buying a new case, users can refresh the old case with their favorite images taken on the internet. According to the Fastcompany , while the color-changing cases are quite attractive, the work has a long way to go before it achieves success in consumer products. UV rays can be dangerous when in contact with the skin, which is why the MIT researchers used a special UV box to house the projector. In areas specializing in the production of color-changing cases, they are fully equipped with safe and convenient machines, so this is no longer a difficult challenge. However, for others, this option is quite expensive and cumbersome, so not many people will invest in this paint and hope to apply it to products such as bumpers, car covers, etc. The second problem is that these designs will fade over time, because UV rays are everywhere. Mr. Wessely said the paint can maintain color and contrast for about 2 days in an office environment, which is already away from the sun (which contains UV rays). If you take out the products that are coated with color-changing paint, it will significantly shorten the color fastness time. Color changing phone cases. Photo: MIT. While the idea of ​​painting a new design on an iPhone case or coffee cup will help with the problem of fading, this habit may be difficult for many people to maintain. Another more desirable aspect that Mr. Wessely’s team is working on is bringing color-changing paint technology to the fashion sector. They are developing fibers that can be re-woven into anything like clothing or shoes… with properties like light-sensitive dyes. This led Mr Wessely to believe that they could integrate tiny light bulbs into clothing that would make the wearer stand out. In this case, when the light is in close contact with the dye, the discoloration process is more efficient. “We can make the color change instantaneously, even under a second,” says Wessely. Besides, he said it is possible to use a coating that absorbs ultraviolet rays. Imagine a t-shirt that changes to a new slogan every hour, or a purse that changes color to match that day’s outfit. To create such a product, the team would have to create specialized yarns and a software that can put printed patterns onto textiles; This fabric can stretch and contour the human body. According to the Fastcompany , this idea is not easy to implement, partly because the field is relatively young. “Usually you have 10 years of studying something. But we are only just beginning to explore this new field,” said Wessely.

It is extremely important to arrange items by classification, color, and size so that they are neat. They help you never have to rummage through just to find one thing and always easily see what you’re looking for. Use clear cardboard or plastic boxes to prevent items from getting mixed up. Sort items by classification, color, size. 2. Big and small space division Instead of spreading items evenly throughout the house, divide the space big and small. The main space of the house should reduce furniture, making the space larger. Meanwhile, the storage items should be concentrated in one place, easy to find when needed, and save space. Storage items should be concentrated in one place. 3. Hide the clutter When the storage items are gathered in one place, of course this area will become very cramped and messy. Use curtains to hide the clutter and make the space feel more open. Use curtains to hide the clutter. 4. Wrapping paper for storage objects If reusing storage items such as suitcases, wooden crates, tin cans… they don’t always look good. Take the trouble to buy wrapping paper and wrap those things outside. Depending on the color of the wrapping paper you can turn them into a beautiful accent in the room. Use paper to wrap cans, wooden crates, tin boxes for reuse. 5. Take advantage of standing space What has no place to store on the ground, hang it up, from small objects like a key or as big as a bicycle, there is always a solution for you. If you know how to make use of vertical space, your house will save considerable space. And here are some suggestions for using vertical space: Behind the door: For many people, the door only works to ensure privacy, so the space behind the door is often neglected and wasted. You can fully utilize the back as an efficient storage space. Take advantage of the back of the door for efficient storage. Horizontal bars: Used to hang shoes, clothes or bags. Do not underestimate these horizontal bars, they are extremely useful. Pegboard : Perforated panels are the ultimate solution for heavy hanging objects. Not to mention, its advantage is that you can decorate and arrange the position according to your liking. If you know how to sort, pegboard Can completely become a “work of art” in the house! Note, depending on the capacity of the hanging object that drills a large or small hole, the heavier the object, the larger the hole for the hanger must be. If you know how to sort, pegboard Can completely become a “work of art” in the house! Tube length: The long tube, after being glued to the wall, can be used to store light objects such as stationery, needles…. The beautifully wrapped long tubes both help to store your belongings and beautify your home. Wall mount: Used to store clear plastic jars that you can hold 1001 things in. The wall mount is both space-saving and holds many things. Paper towel holder: Reusable tissue holder to store keys or ribbons. Smart reuse will bring convenience to your life. “Sewing” the bag for the wall Empty walls are a great storage space if you know how to use them. 6. Label the boxes Store unused or rarely used items in boxes, wicker bins or simply cardboard or plastic bins. Notes and labels for each type of box/box. Even when stacking boxes of all kinds on top of cabinets or in storage, you won’t have to worry about messing up your search if you label and label them carefully from the beginning. 7. Use trays with dividers, compartments Divide compartments in drawers to store things more scientifically, allowing separate, unmistakable items to be stored, making it easy to find when needed. Keeping things apart will help keep items separate, unmistakable, making it easy to find when needed. The trays will help you store your sundries neatly. The trays will help you store your sundries neatly and less cluttered. In particular, use a tray with divided compartments, allowing to store separate items, not being confused, making it easy to find when needed. 8. Store items on top of cabinets or under the bed These are the two most often neglected spaces while they can completely store a lot of items. These are the two spaces that are often neglected the most, while they can completely store a lot of items, without creating a feeling of being cramped or cluttered with people in the house.

However, up to now, there have been many times of debris falling from space on Earth, including an event that happened in 2020. Photo: CNN The good news is that the debris falling on Earth generally poses little threat to human safety. As Jonathan McDowell, an astronomer at the Center for Astrophysics at Harvard University, told CNN: “It’s not the end of the world.” Even so, the issue still raises related questions about debris in outer space, how uncontrollably they fall to Earth, and what precautions should be taken when that happens. out? There have been many times of debris falling back to Earth Most of the debris would be burned in the atmosphere before having a chance to make any impact on the Earth’s surface. However, some large objects, like rockets, may remain intact when returned to Earth and are also likely to fall into populated areas. In 2020, one of the largest debris in space flew over the skies of Los Angeles and Central Park in New York City before falling into the Atlantic. This is an empty core from Chinese missiles, weighing nearly 20 tons, is the largest piece of uncontrolled trash when it fell back to Earth since 1991 and is the fourth largest piece ever. Other larger pieces are from NASA’s Skylab space station in 1979, the missile core of Skylab in 1975, and the Soviet Salyut 7 space station in 1991. The space shuttle Columbia from 2003 could also be included in the list. This is because NASA lost control of the ship when it returned to Earth. How many debris are floating in space? The answer is a lot. Above us there is a “cloud” of more than 9,000 tons of space debris – the equivalent of the weight of 720 school buses. This cloud contains hundreds of thousands – maybe even millions – of objects orbiting uncontrollably, including used rocket propulsion engines, dead satellites and debris from the army’s anti-satellite missiles. These debris are concentrated in the orbital regions closest to the Earth’s surface. And while it does not pose a significant threat to humans on the ground, it does pose a threat to many active satellites that provide a number of services such as climate tracking, studying Earth climate. Land and telecommunications service providers. These debris also threaten the International Space Station (ISS). The ISS station had to readjust its orbit several times last year due to space debris. “A few years ago, we had about 1,000 satellites in orbit, but now we have 4,000 satellites,” said McDowell. The tricky problem is that space transport experts do not have a complete map of the objects orbiting the Earth. Potential collisions are being tracked using government or private trackers on the ground, but the process is largely predictable. When will Chinese rockets return to Earth? The Long March 5B missile is expected to return to Earth’s atmosphere around May 8, according to Defense Department spokesman Mike Howard. Space Command is currently monitoring the missile’s path. According to Howard, the point of return to Earth’s atmosphere could only be accurately determined a few hours ago difficult to start falling back to Earth. However, Space Control Unit 18 will update the missile’s exact location via the Space Track website. Astrophysicist McDowell explained that determining where debris could fall to Earth is almost impossible at this point because the rocket’s travel speed can vary and with only 1 change. Very small is enough to greatly change the direction of the missile. “We expect it to return around May 8-10. During those two days, it will travel around the Earth about 30 times and at a speed of about 18,000 km / h “, according to Mr. McDowell. Still, the oceans are still the safest place for debris to land, as it occupies most of the Earth’s surface. Do people need to be on guard? There’s no need to be on guard, said Mr. McDowell. “The risk of it causing some damage or hitting someone is very small. It can still happen, but the chance of it hitting you is extremely small. I won’t waste a second worrying about it. Because there are still other bigger things to think about, ”said McDowell.

The scene of the launch of the Truong Chinh – 5B missile in Hainan on April 29 (Photo: Tan Hoa commune). According to the Hong Kong news site the East On May 9, China’s Office of Construction to put people into space on Sunday morning said that fragments of the end-propeller compartment of the Truong Chinh – 5B (CZ-5B) rocket launched by China from the Van Xuong launch site, Hainan will return to the atmosphere at 9:12 am on the same day (Hanoi time); the area in which it re-entered the atmosphere lies above 28.38 ° east longitude and 34.43 ° north latitude, in the Mediterranean sky. The European Union’s Center for Space Monitoring and Monitoring (EUSST) had previously predicted that the rest of the missile bay would return to the atmosphere at 2:32 a.m. GMT on Sunday (9:32 a.m. Internal on Sunday), with an error of adding or subtracting 139 minutes. According to EUSST, the probability of a missile fragment falling in densely populated areas is very low, but it can still happen uncertain due to the object’s uncontrolled. Thien Ha module of 100m3 capacity was launched by missile into space. American company Aerospace Corporation again stated that missile fragments will fall to the ground at 3:30 am UTC on Sunday (ie 10:30 am Hanoi time) with an error of plus or minus 4 o’clock. Actual drop times may vary. The Truong Chinh – 5B missile was launched into space by China on April 29 to bring the 100m3 Thien Hoa core module into orbit, this part will be the place for 3 astronauts to live and live on the Air Station. the Chinese Heavenly Palace. The launch of the core module is the first of the 11 missions required to complete the installation of a space station. The carrier was successfully put into orbit, but the rocket’s propulsion chamber lost control and fell back to Earth. According to the Ministry of Foreign Affairs of China, the fragment of the missile will catch fire when it enters the atmosphere, so the potential for harm is extremely low. The missile falls down (all brown parts and 2 support chambers) with the trajectory of the debris moving around Trac Dat. Black dot is the falling point predicted by Aerospace on May 8 (Image: UDN). However, there has been controversy surrounding the rocket’s falling back to Earth. The US Army Space Command said on May 4 that they “are closely monitoring and reporting to the public the location of the missile debris. It is currently impossible to determine where it fell to Earth. Asked during a press conference on May 6 whether the US shot down fragments of Chinese missiles, US Defense Secretary Lloyd Austin said: “We expect it to fall where it will not cause it. casualties; hope it will fall into the ocean or the like “and said the US” has no plans to shoot it down “. During a press conference at the White House on May 5, when asked: “If the Chinese missile fragments cause harm to the US, will the US claim compensation,” White House spokesman Jen Psaki said: “No. it’s time to discuss this. We are tracking its position through Space Command and hopefully not in the end. ” “The US pays attention to solving the problem of space junk caused by increased activities in space,” she emphasized. The US hopes to cooperate with the international community to promote responsible behavior in the space. Photo of debris caught fire while crossing Italy on the night of May 8 (Photo: virtualtelescope.eu). Meanwhile, the Chinese side accused the Western media of overstating the fact that their missiles “lost control” and could cause great damage. According to the Reuters , sheet Global Times China’s claim that reports of the missile “out of control” and can cause damage are just “Western hype”. The Chinese Ministry of Foreign Affairs believes that the probability of harm caused by this process is extremely low. Mr. Uong Van Ban, spokesperson for China’s Ministry of Foreign Affairs on May 7, when answering questions from reporters during a regular press conference, said that international practice allows rockets to enter the atmosphere to throw and destroy. He said: “As far as I know, this missile applies a special engineering design, most of the parts will be worn out and destroyed during the return, potentially harmful to cargo operations,” he said. zero and above ground is extremely low; The relevant authorities will promptly notify the outside situation ”. The Chinese rocket propulsion chamber fell down before (Image: weibo). The Chinese side is very interested in monitoring the reintegration of the missile debris atmosphere, but declined to answer questions about where it was expected to fall, said Uong Van Ban; instead, he advised reporters to “consult the relevant agencies”. However, the National Aerospace Bureau of China did not respond to relevant questions from reporters Bloomberg . Since the US Skylab space station was out of orbit and crashed into Western Australia in 1979, most space programs have tried to avoid sending large missiles into orbit, because in this case Their return to Earth will be difficult to predict. According to the news of The Guardi This uncontrolled China Changzheng-2B missile compartment is 30 meters long, 5 meters wide and weighs 21 tons, it could become one of the largest space debris falling to the ground. Photo of Truong Chinh – 5B rocket propulsion compartment falling on May 6 (Photo: virtualtelescope.eu) This missile compartment is currently freely acrobatic around Earth, is about to enter the lower atmosphere, and is expected to fall uncontrollably down to Earth. Its orbital tilt is 41.5 degrees, meaning that areas of the Earth in the range from the north like Chicago, New York, Rome, Beijing, Hanoi and south to New Zealand, Chile are all on the Road moves and may fall. Although scientists expect that most of the debris will be burned and destroyed as it enters the atmosphere, there are still some that will fall to different places on earth, these parts include a metal and glass numbers have not been burned. Some scientists believe that it is irresponsible for China to let the missile debris return to Earth uncontrollably. “They (China) are responsible,” said Paulo Lozano, director of the Space Thrust Laboratory at the Massachusetts Institute of Technology (MIT). They either did not provide enough information or did enough work during the design process to prevent the space object from returning uncontrollably back to Earth. I think that’s very important …. Hope they won’t fall on land, especially in public places, the consequences will be very bad. ” Lozano said that almost all missile launches in the US require a second stage. During this phase, the engine will restart to bring the missile back to earth in an area that does not have any. designated person. However, the Truong Chinh – 5B missile does not have this design. According to Jonathan Black, director of the Maritime and Aviation Systems Laboratory at Virginia Tech, the technology has been in use for the past ten years. Although the Truong Chinh – 2B missile was just launched in late April, its technology is still decades ago. Scientists speculate that the high cost may be the reason China is not adopting new technologies. The propellant compartment of the Chinese missile fell to Guangxi province before (Image: weibo). Harvard astrophysicist Jonathan McDowell criticizes China for being negligent in this regard, not letting objects heavier than 10 tons fall to Earth from space. He said potentially dangerous debris may not be completely burned when returned to the atmosphere at supersonic speeds, but the probability of falling into the sea is higher because 70% of the earth’s surface is covered by Ocean. However, Mr. McDowell told Reuters that it was still possible that missile debris could fall on the ground; can even fall in densely populated areas, like fragments of another Truong Chinh-5B rocket that crashed on Côte d’Ivoire (Ivory Coast) in May 2020, destroying many buildings, But luck did not cause any casualties. Follow the latest information from the page the East at 11:33 a.m.: The China Space Construction Office announced: fragments of the last compartment of the missile carrying Truong Chinh -5B returned to the atmosphere at 10:24 am. The fall zone was located at 72.47 ° east longitude and 2.65 ° north latitude over the Indian Ocean near the Maldives, most of the equipment was burned down during the reintegration of the atmosphere.

People in Brazil are examining the debris believed to have belonged to a European spacecraft in 2014. Photo: Getty. Sea of ​​Japan (also known as East Sea) The phenomenon of debris falling from space falling to the ground and causing damage was first recorded in 1969. That year, Japanese diplomats informed the United Nations of an unknown object from the falling space. Down and collide with Japanese cargo ships moving off Siberia (Russia). The collision caused serious injuries to 5 crew members. Shortly after, Soviet ships appeared at that time looking for debris. Japanese officials said the debris was identified by experts as part of the Soviet spacecraft. However, this information was initially kept private by Tokyo because it did not want to create conflicts with Moscow, according to the report AP . State of the Northwest Territories, Canada The danger of an object from space became apparent in 1978, when Cosmos 954, a satellite powered by the atomic energy of the Soviet Union, fell to Earth. The incident caused radioactive debris to spread throughout the Northwest Territories, Alberta, and Canada’s Saskatchewan province. After the incident, the Canadian government organized a large-scale “Morning Light Campaign” to search for tiny pieces of radioactive material falling on the arctic tundra. The cost for this campaign is nearly 14 million CAD (equivalent to 11.5 million USD). A fragment of satellite Cosmos 954. Photo: United States Department of Energy. Canada demanded that the Soviet Union compensate at the time for CAD 6 million ($ 5 million), but Moscow ended up paying only half of that amount. State of West Australia, Australia In 1979, Skylab – the first space station of the US Aerospace Agency (NASA) – crumbled while returning to Earth’s atmosphere. The incident caused many debris to fall throughout the farm town of Esperance in West Australia, Australia. The Skylab space station was photographed by the last crewman before falling apart on July 11, 1979. Photo: NASA. “It’s the best fireworks display you’ll ever see,” described Brendan Freeman, a retired farmer. ABC . The debris did not cause great damage, but for fun, the town authorities Esperance wrote a $ 400 fine letter to NASA for littering. NASA did not pay the fines, possibly out of fear of setting a negative precedent. By 2009, a DJ in the city of Barstow, California (USA) called to raise funds and bring fines to pay the town of Esperance. Lakeport, California, USA An early weekend in 1987, a retired aircraft mechanic living in a town near Mendocino National Forest, in northern California, heard gun-like noises outside the bedroom window. After searching, he discovered a scorched metal piece longer than 2 meters in the alley next to the house. Analysts at the US Air Force determined this object was most likely a piece of debris falling from a Soviet missile. This missile has previously been seen flying across the sky while being burned and dropped to Earth. “It’s interesting because things like that don’t happen around here very often,” said Maggie Pickle, the mechanic’s neighbor. AP . Tulsa, Oklahoma, USA Lottie Williams held up a piece of debris that fell on her shoulder from a US Delta II rocket in 1997. Photo: Tulsa World. One morning in 1997, Lottie Williams was walking with friends in Tulsa city park when he saw something like a comet across the sky. The object fell on Mrs. Williams’ shoulder, but the force of the impact was very light, almost insensitive. The object identified by the scientists was most likely a piece of the US Delta II rocket. Fragments are kept by Mrs. Williams as a souvenir. “I must be very lucky for the debris to be so light. It was one of the strangest things that ever happened to me, ”Mrs. Williams told NPR in the interview many years later. Eastern region of Texas and Louisiana, USA In 2003, the American space shuttle Columbia collapsed while returning to the atmosphere, killing seven astronauts on board. Where the wreckage of the space shuttle hit the ground, temporary memorials were built for the crew. Rural residents along the Texas-Louisiana border reported seeing debris from the ship fell into a water storage tank or through the roof of a dental office. Someone even tried to sell a piece of fragment on an eBay e-commerce site for $ 10,000. Finally, 84,000 pieces of debris from the ship in distress were collected after extensive searches in swamps, forests, and grasslands. These debris were used to rebuild the ship and identify the cause of the disaster. Ivory Coast In May 2020, another Chinese 5B Truong Chinh missile also crashed on Earth. The missile was initially thought to have crashed into the Pacific Ocean, but some people reported hearing ultrasonic explosions and seeing metal debris falling from the sky. This shows that some parts of the Truong Chinh 5B missile fell in the village of Mahounou, on the Ivory Coast. China’s Truong Chinh 5B missile launch in late April in Hainan province. Photo: Getty. However, there were no reports of human casualties following the incident. The discovery of tube fragments longer than 12 m also seems to help this area get more attention. Grant County, Washington State, USA The most recent cosmic waste incident happened just over a month ago, when a private aerospace company SpaceX rocket exploded over the Pacific Northwest. The explosion created a “light show,” which caused some at first to mistake it for a meteor shower, according to the report The Verge . A piece of equipment from the missile crashed on a farm in Washington state, leaving a mark more than 12 cm deep on the ground, The Verge reporting. A similar object was also discovered by fishermen off the coast of Oregon a few days later, but authorities have not confirmed whether this is debris from the SpaceX missile or not.

San Luis Valley, Colorado, USA: Also known as “UFO hot spot in America”, the San Luis valley is a place associated with many speculations about the appearance of UFOs and mysterious stories about the sky. Broad Haven, UK: This area became famous in 1977 when a group of students claimed that they had seen a UFO shaped like a “silver cigar-shaped spaceship”. Bonnybridge, Scotland: Residents of this part of Scotland have claimed they have seen an unidentified flying object (UFO) and flashing lights every year since winter 1992. Area 51, Nevada, USA: As one of the most secret and mysterious places in the world, Area 51 is a military area of ​​the US Air Force that is associated with stories of UFOs and strange phenomena. Interpretation occurred at this location. Nullarbor Plain, Australia: UFO sightings in southern Australia have been circulating since the early 20th century, but it was not until January 1988 that the phenomenon became common when many witnesses reported that they had seen the Bright and strangely active are believed to be of aliens. A family of four driving in the Nullarbor Plain claimed that they were chased, attacked and lifted by a large glowing object. Since then, the authorities say they have received hundreds of reports of similar incidents each year. San Clemente, Chile: The small Andean town has recorded many sightings of UFOs and it is even known as the “UFO capital of the world”. This place is also the location for 2 of the most modern observatories in the world. Nazca, Peru: The Nazca lines are geoglyphs – giant drawings on the ground are an archaeological mystery that has yet to be answered. While some consider it to be the work of the Nazca civilization that lived between AD 1 – 700, another theory explains that the drawings may be the remaining traces. again when a UFO lands. Wiltshire, UK: UFO stories in Wiltshire began at Christmas 1964 when locals recalled seeing “shock waves” and a “bizarre orange flame” in the sky. Since then, the area has recorded a number of strange UFO-related phenomena, the most recent of which occurred in February 2016. Roswell, New Mexico, USA: This site is the most famous place for the UFO conspiracy theories. Roswell became a popular name in the late 1970s when an object was dropped here. Although the US government released data showing that the object was a hot air balloon, rumors of UFOs, aliens or hidden mysteries still exist to this day. Extraterrestrial Highway, Nevada, USA: Spanning over 160 km near Area 51, the Extraterrestrial Highway is a site that records countless UFO sightings and strange lights. Phoenix, Arizona, USA: On March 13, 1997, strange lights and a UFO were discovered in the sky in the US states of Arizona and Nevada. Witnesses claimed to have seen a V-shaped flying object with five mysterious flashing lights. Colares, Brazil: This city in the north of Brazil attracts the attention of people who believe in the existence of UFOs in 1970 after locals reported that they were attacked by aliens. burns on the skin. The cases occurred so many times that the Brazilian government launched an investigation called Operação Prato but it ended in 1978 when nothing was found. Triangle M, Russia: Located in the Perm region near the Ural Mountains, this remote land was only known in the 1980s. Some witnesses have reported strange phenomena they encounter here such as lights bizarre, UFOs, strange symbols in the sky, giant footprints or mysterious mysterious shapes. Melbourne, Australia: After the Westall event in 1966 when more than 100 Westall students and teachers claimed to have seen 3 metal objects in the sky (as shown in the picture), this area has repeatedly recorded cases. the same, similar. Witnesses even claimed they met “men in black”. Manitoba, Canada: The Lake Falcon incident in 1967 was the most famous UFO sighting case in Canada. This happened when a man came home and got sick after spending a weekend in the area. The man claimed to have seen two cigar-shaped objects hitting him with hot gases and burning his clothes. Later, many locals also reported seeing red fireballs and wheel-shaped objects in the sky. Joshua Tree National Park, California, USA: This national park was once believed to be an alien base. This is also the site of the Center for Extraterrestrial Intelligence (CETI) – an institute that looks for signs of outer life to prove that we are not alone in this universe.

However, one sense that humans can soon master, is bat-like echolocation. Sixth sense experiment According to the Popular Mechanics Scientists in Japan have tested this ability in a laboratory, proving that humans can use it echolocation , or the ability to sense echoes for navigation. This ability helps people recognize the shape and rotation of many objects. Thanks to that, people can “see” in the dark. When the volunteer presses the tablet, a synthesized echo is emitted from the amplifier speaker (red line). The sounds obtained with the binaural are 1/8 of the original pitch by reducing the sampling frequency, which is transmitted into the volunteer headphones (green line). Photo: Miwa Sumiya. As bats fly around objects, they emit intense sound waves from different angles and bounce off at isolated intervals. Thanks to that, this tiny mammal can determine the topography, texture or movement of an object. According to Dr. Miwa Sumiya, if humans were able to perceive the patterns of time-changing sounds similar to bats, they could see the world in new ways. Dr. Sumiya, a researcher at the Center for Nerve and Information Networks in Osaka, Japan and was the first author of a paper to appear on Plos One on this topic. “Testing that humans are capable of detecting multiple environments via sound waves could add a new step in understanding the complexity of the human brain,” Sumiya said. According to Sumiya, humans have the ability to further understand the perception of other species (such as bats) by comparing with knowledge gained in echolocation studies of humankind. To test this theory, Mrs. Sumiya’s group made a meticulous arrangement. In one room, the researchers gave volunteers a pair of headphones and two tablets, one that produced a calibrated signal using a synthesized echo, the other to listen to pre-recorded echoes. . In room 2, only the strangely shaped 3D axes stand in one place and rotate around themselves. When prompted, 15 volunteers turned on echolocation signals from their tablets. The sound waves emit each beat, travel to room 2 and hit the 3D axes. Participants need a little bit of imagination to convert sound waves into a certain object. Sumiya explained that the synthesized echo-locating signals used in this experiment were high-frequency signals up to 41 kHz, which cannot be heard by humans. Dolphins are also a mammal that uses echolocation to detect and hunt. Photo: Getty Images. Researchers used a humanoid (1/7 the size of a real skull) to “hear” the sound in room 2 before passing it on to volunteers. The fake head is equipped with 2 microphones attached to the two ears and creating a 3D resonance. The sound output is quite similar to the surround sound experienced in movie theaters. Reducing the frequency of the echoes in both ears enabled volunteers to hear “with the feeling of being heard in real space”. Many people like to listen to podcasts or watch videos with headphones to create surround sound and give a tingling sensation in their ears. This is called the Autonomous Sensory Meridian Response, or ASMR. Result Finally, researchers and volunteers guessed whether echoes were coming from stationary or spinning objects. At the end of the experiment, the volunteers were able to accurately identify two pillars thanks to the time-varying echolocation signals emanating from them. Identifying clue is thanks to the pitch and timbre. However, it was difficult for them to discern the shape of the standing pillars. Sumiya’s group study is not the first to test the ability of human echolocation. Previous studies have shown that blind people can use mouth-clicking sounds to see 2D objects. However, Ms. Sumiya said her experiment was the first to specifically explore the ability of echolocation to change over time. The researchers said their work is evidence that both humans and bats are capable of decoding objects through sound. In the future, engineers could apply this technology to wearable devices such as watches or glasses to improve how visually impaired people can navigate the world, except for headsets.

If the owner wants to increase his fortune, he can put an object called a “treasure box” under the bed. According to feng shui, put a box under the bed, all your dreams and wishes will be filled in. Each time you sleep, your body will absorb positive energy from the box, helping you to fulfill your wish soon. Treasure box can be made from many different ingredients. Wooden boxes symbolize fertility and bloom, helping couples who are expecting their children to have good news soon. The clay box will help the road of fame to flourish. Boxes made of gold, silver, and precious stones help bring wealth, wealth and wealth to the homeowner. Homeowners should put precious jewelry, valuable money bills inside the box to stimulate money increase. It is forbidden to put the coin in the box. If your family life is having problems, your love is not going well, you can put aromatherapy essential oils and scented candles in the box. But this object can arouse feelings of love, love feelings of couples more salty. If you want your health, please put pearls with the image of turtles and deer in the box. After 3 months, bring the box clean once to increase the ability to attract fortune, avoid bad luck. According to feng-shui, under the bed must be ventilated to help the air in the room be airy, creating the circulation of air, not affecting the health of family members. However, some bed designers are now thinking like a kind of closet, tightly sealed. As such, air will not be able to circulate. * Information for reference and contemplative nature.

Kenya Airways’ aircraft at Jomo Kenyatta International Airport in Nairobi. Heartbreaking discovery On the afternoon of June 30, 2019, 31-year-old British software engineer Wil was outside his house in Clapham (southwest London), drinking beer while chatting with a friend, above his head. , the planes were also rushing to Heathrow airport to end their journey. Taking out his phone, Wil shows him an app that tells the user the route and pattern of any passing aircraft. When he saw an airplane passing by, he opened the application to view information, then raised his phone to shade the sun and squinted at the sky. Suddenly, Wil saw something falling from the sky. “At first I thought it was a bag, but after a few seconds, I discovered the object was quite large and fell very quickly,” Mr. Wil said. Wil thinks that the object could be part of the landing gear or the luggage in the cargo hold. However, he suddenly remembered a long-read article about people hiding tickets on planes. Wil does not want to believe in this possibility but cannot deny the object gets closer and closer. “In the final seconds before the object lands, I see limbs. I think it’s a person, ”continued Wil. Shortly thereafter, Wil opened the flight determination application, and his friend called the police to report the news. According to information on the phone application, the plane that has just passed over that area is Boeing 787-8 Dreamliner carrying number KQ 100 of Kenya Airways. The man was dropped from a plane of Kenya Airways 1000m to the ground. After that, Wil drove his motorbike to find where the object fell, and mumbled to pray that he would only see a coat, a bag or something on the ground. When he went to the next route, he met a police car in the opposite direction and decided to follow. The destination is on Offerton Street, 300 meters from Wil’s house. When he arrived, Wil saw John Baldock, a gray-faced man standing dumbfounded outside a house. Looking through the window, Wil noticed that the inner garden was “completely destroyed”. “The first thing I told John was to ask if it was the same person, because I’m still not 100% sure. He said nothing, just looked at me and nodded, making my heart heavy, “Wil said. That man fell from a height of more than 1,000m to the ground. This is an airplane ticket evader. Hard search On the day of the incident, because the London Police Department’s unit in charge of searching for the missing people was overloaded, agent Paul Graves of the voluntary crime unit was in charge of the investigation. As an experienced senior detective, Graves has more than 30 years specializing in handling stabbing, shooting, kidnapping and murder conspiracy. He hopes to soon identify the man “fell from the sky” and return the body. After receiving the report, the police quickly went to Offerton Street, talked with Wil, John and people living in the area, and contacted Heathrow airport. The airport sent staff to inspect the landing gear – the area of ​​the aircraft’s landing gear will retract after takeoff – aboard a Kenyan Airways Boeing. There was barely enough room for one person to hide inside, and after checking in, an old backpack with the initials MCA was found there. The backpack does not contain any important clues, only contains a few pieces of bread, a bottle of soft drink, a bottle of water and a pair of sports shoes. “Food, water and shoes are the definition of survival for that person,” Detective Graves said. However, there was also some Kenyan coins in the backpack and a bottle of Fantamà, according to verification sold at a store in the country, showed that the stowaway was almost certainly on board there. The flight initially departed from Johannesburg, South Africa to Nairobi, Kenya. So the elimination of the possibility of a man getting on a plane from South Africa is a remarkable discovery: At the Lambeth Morgue, pathologists took samples of the man’s DNA and duplicate copies of his fingerprints. hand him and send it to the authorities in Kenya. However, the DNA determination later showed that it did not match anyone in Kenya. Graves hopes that he will have better luck with fingerprints as many problems in Kenya require candidates to have fingerprints. But the smuggler’s fingerprints were also not on the Kenyan police database. The incident meanwhile attracted the attention of public opinion. Because the situation of migrants betting their lives to reach Europe has appeared so often in the newspapers, and this is a completely different thing: an unidentified man, from a country about a third of the population lives on less than $ 2 a day, crashing the bottom of a plane into one of the wealthiest places in London. According to statistics of the US Federal Aviation Administration, from 1947 to February 2020, 128 people around the world tried to smuggle planes in this way. More than 75% of them were killed. The stowaway can fall off the plane during take-off, as in the case of 14-year-old Keith Sapsford falling from a cabin landing a Douglas DC-8 departing from Sydney, Australia for Tokyo, Japan, in January. 2/1970. Even if they survive the take-off, the stowaways can be crushed as they return, as Adonis Guerrero Barrios died in July 2011. The 23-year-old has climbed into the cockpit of the Airbus A340 from Cuba to Madrid, Spain. Even with luck avoiding the above possibilities, those who cling to the plane still face the cargo. Other deadly risk series. For example, within 25 minutes of take-off, most passenger aircraft reach an altitude of nearly 11 km, the outside temperature is approximately -54 degrees Celsius, the air pressure is about 4 times lower than normal, preventing the human lungs from getting enough oxygen from the air, which can cause heart failure and brain death. If the stowaway somehow managed to survive the journey, they would surely lose consciousness once the plane began to descend. Therefore, when the aircraft opens the door to lower the landing gear, usually within 8 km of the runway, they can fall freely. This is why bodies are sometimes found south of London, near Heathrow’s route, as in the case of Pakistani elder Mohammed Ayaz who died from falling from a British Airways flight into a Homebase parking lot. , also in Richmond in June 2001. There are also rare instances where some of the stowaways still survived that scientists have not fully explained these cases. In September 2019, three months after receiving the investigation, Agent Graves flew to Kenya, hoping to find out what details could help identify the mysterious but futile man. Dead end, he decided to use the last resort, thanks to the help and spread of the media, but failed. At the end of 2019, Kenyan officials decided to close the investigation. This is also seen as typical of the tragic cases of migrants. Many of them drowned at sea, were electrocuted in cross-strait tunnels, or assaulted to death by racist mobs. According to the Project Lost Migrants, 10,134 have been killed on the global migration routes since 2014. That might just be the tip of the iceberg.

Yudo Margono, the naval chief of staff, told reporters that authorities had found an object with “high magnetic force” floating at a depth of 50 to 100 meters. Authorities hope the object could be the missing submarine and are currently waiting for a naval ship with underwater detection facilities to help them investigate the object further. The Indonesian military has so far declined to comment on whether the decades-old submarine, carrying 53 crew, is overpowered. Submarine KRI Nanggala-402 – Photo: Reuters However, they said the submarine may have sank to great depths after a power outage left the crew unable to control the ship. If the object is found to be part of the submarine, the navy suspects the crew may have discharged its fuel load after a power outage to allow the submarine to float. Navy officials feared the submarine might explode. Collin Koh, a naval expert and research fellow at the S. Rajaratnam School of International Studies in Singapore, said damage to the fuel tank could cause “big trouble”. Naval spokesperson Julius Widjojono previously told KompasTV that a battery-powered submarine when submerged could only maintain a depth of 250 to 500 meters. “Anything that makes it go deeper than that can be fatal and dangerous,” he said. The waters in the region are shallower than in other parts of the archipelago but can still reach depths of more than 1,500 meters.

The Ministry of Labor, Invalids and Social Affairs has just submitted a proposal to the Government to develop the Law on Social Insurance (amended) (social insurance). According to the Ministry of Labor, Invalids and Social Affairs, the current development of social insurance beneficiaries is below potential, many people are subject to compulsory social insurance but have not yet participated. The current law is “missing” many subjects Data from the General Statistics Office shows that in 2019, the whole country had more than 5.6 million individual business households, eight times the number of enterprises. According to the tax authorities, the country has more than 1.7 million times of households paying tax (households with turnover less than 100 million VND / year do not have to pay). However, this group is not subject to compulsory social insurance, so very few individual business householders participate in voluntary social insurance. According to data from the Ministry of Planning and Investment, in 2019 there are about 23,000 active cooperatives, attracting nearly six million members. In which 1.2 million people work in the cooperative area. But according to the report of the social insurance agency, there are nearly 7,000 cooperatives registered to participate in compulsory social insurance for about 41,000 employees. “Through a survey in some localities, many business managers, managers and executives of unpaid cooperatives wish to participate in compulsory social insurance …” – said by the Ministry of Labor, War Invalids and Social Affairs. Therefore, the Ministry of Labor, War Invalids and Social Affairs proposes to add compulsory social insurance participants for individual business householders, business managers, managers and cooperatives without pay. Specific provisions on compulsory social insurance for employees who work part-time and participate in compulsory social insurance with civil servants, public employees, part-time workers at commune level who also sign labor contracts. moving. According to the assessment of the Ministry of Labor, Invalids and Social Affairs, the above provision helps to increase the income of the social insurance fund in the short and medium term, while also increasing the expenditure from the social insurance fund in both short, medium and long term. The number of people who receive one-time social insurance to take care of their immediate life tends to increase. Photo: V.LONG Need to have a share in participating in social insurance According to the Ministry of Labor, Invalids and Social Affairs, the nature of risk sharing is only evident in sickness, maternity, labor accident, and occupational disease regimes. The pension policy is designed to be heavy on the principle of payment – benefit (pay more and enjoy more and vice versa) but lack attention to the principle of sharing between high and low salary people. According to data reported by the Vietnam Social Security, by the end of 2017, the average pension is 4.26 million VND / person / month. In which, the highest is 101.3 million VND / person / month, the lowest is 1.3 million VND / person / month (more than 4,100 people have this pension). The large gap in pension discourages people with low wages, leading to an increase in the number of people who want to receive one-time social insurance. In recent years, each year about 600,000 people enjoy one-time social insurance and leave the social insurance system. Therefore, this agency proposes to amend the method of calculating the average monthly salary paid for social insurance to calculate the pension for the employee, in the direction of the average monthly salary paid for social insurance of that person and the average monthly salary paid for social insurance. of people participating in social insurance to calculate their pensions. Thus, there will be a certain share between the high-paid and the low-paid. “The narrowing of the pension gap will encourage the participants of low-wage social insurance to reserve the time to pay social insurance to enjoy the pension instead of receiving one-time social insurance …” – The Ministry of Labor, War Invalids and Social Affairs assessed. The Ministry of Labor, Invalids and Social Affairs said that if allowed, the unit would be authorized by the Government to submit to the National Assembly for consideration and comments on the first bill at the second session of term XV (October 2022). Submit to the National Assembly for approval at the third session, term XV (May 2023). “Tighten” regulations on receiving social insurance once Currently, the condition to receive one-time social insurance is quite easy. Specifically, after one year of not participating in social insurance, the employee can receive one-time social insurance with the entitlement of 1.5 months of salary for each year participating in social insurance before 2014 and two months of salary for each participating year thereafter. Thus, with the contribution to the pension and death fund of 8% of the salary from the employee, the one year of paying 0.96 months of salary, the entitlement to two months’ salary upon receiving one-time social insurance is considered profitable. Along with having to wait too long to enjoy pension, employees will want to receive one-time social insurance to meet immediate needs. Therefore, it is necessary to adjust the regulations on one-time social insurance entitlement in the direction of having a roadmap to only deal with employees when they have reached the end of their working age but are not eligible for pensions without the need to continue paying. . Except for the case of going abroad to legally settle down or suffering from a dangerous disease and wishing to receive it once, or if the case is not yet over the working age, but receives one-time social insurance, the rate of entitlement is lower. In addition, the law also needs to amend the conditions for enjoying the pension in the direction of gradually reducing the number of years of minimum social insurance payment from 20 years to 15 years, towards 10 years with an appropriate calculated benefit level, creating conditions for The elderly, with a low number of years participating in social insurance, are entitled to pensions. 65% of Vietnamese elderly do not have a pension According to the Ministry of Labor, Invalids and Social Affairs, by the end of 2020, Vietnam has about 14.1 million people after the retirement age (55 years old for women, 60 years old and older for men). Of which, only over 3.1 million people are enjoying the pension (accounting for 22.1%) and 1.8 million people are enjoying the retirement allowance. There are still about 9.2 million people after the retirement age (accounting for 65%) who have not participated in insurance or any other social security layer.

From Mark Ehren, tagesschau.de The company is located in a place that actually stands for old industry. The automobile company General Motors (GM) has its headquarters in the US metropolis of Detroit. The start-up StockX also resides on Woodware Avenue – whose business does not deal with tires, but with rubber soles. Among other things, sneakers are traded on the StockX Internet platform, sometimes at horrendous prices. The name of the roughly five-year-old company could suggest that it trades in stocks. In fact, it refers to inventory.

A kind of eBay for sneakers

However, StockX hardly has any shoes in stock, but functions primarily as a trading platform. Similar to eBay, the platform brings buyers and sellers together. But in contrast to the well-known auction house, StockX checks the offered goods for authenticity and condition before a transaction. Sellers have to send in their items, the company sends them to buyers after the authenticity and quality checks and processes the payment. At StockX, the motto is: the rarer and more unusual a model, the more popular it is – and the more expensive it is. The prices of some shoes run into six figures. But sneakers for just under 20 euros are also on offer. The price jumps can be enormous. StockX users can see the development in graphics that are confusingly similar to stock market charts. A model was recently offered with a surcharge of almost 30,000 percent compared to the recommended retail price. For its service, StockX collects a commission of three percent plus a transaction fee of almost ten percent for new users.

More than seven million transactions

The high fees apparently do not deter customers: In the past year, StockX processed more than 7.5 million transactions and posted sales of more than 400 million US dollars. More sneakers are now being traded on StockX than on eBay. Company boss Scott Cutler worked for the auction portal before moving to the start-up in 2019. Cutler also gained professional experience in management positions at the New York Stock Exchange.

Eminem and Mark Wahlberg on board

The boom in the sneaker business has long since attracted investors. According to its own statements, the company is now valued at $ 3.8 billion. In addition to traditional investment companies, two celebrities from the entertainment industry are also involved in StockX: the rapper Eminem and the actor Mark Wahlberg. The growth should continue. In addition to sneakers, clothing, handbags and watches, electronic items can now also be traded on StockX. And the company is now also considered a candidate for an IPO.
