To ensure the good completion of this mission and the security of the atomic bomb, the 12 pilots were prepared to sacrifice themselves, once their bomber was shot down, they would end up with pistols or cyanide. before falling into enemy hands. To ensure that even if the mission failed, the secrets of the bomber’s bomb bay would not leak out of his mouth. Six bombers have a clear assignment. Two of them are used to detect the enemy’s situation, the other three need to observe weather conditions. The ultimate bombing target was the 82nd bomber. At 2:40 a.m., they began to slow down the runway and take off. The technical expert began to prepare to throw, open the safety device, install the fuse. At 7 a.m., the meteorological observatory sent back a report that the weather in Hiroshima was very good and the most suitable place to throw. Half an hour later, the 82nd bomber began to make the final preparations. Five minutes later, two enemy bomber scouts left early for safety. At 7:50, the bomber officially entered Japanese airspace. At 8:13, the bomber officially flew into Hiroshima, from the bomber, you can even see the buildings in downtown Hiroshima, as well as many small “ants” walking around. Those are the people who get up early and go out to work. At this point, the people of Hiroshima must have seen these bombers, but according to regular bombing drills conducted by the US military in the past, the people were already familiar with it, not not running away, but looking up. At 8:13, Major Ferrabi was also the bombardier on the mission, he found the Aioi Bridge target within range of the bombing, located in downtown Hiroshima. At 8:15 a.m. 17 seconds, the major opened the door of the bomb compartment, and the “little boy” fell from a height of 10,000m, rushing towards Hiroshima with the sound of demons howling. At the same time, the atomic bomber made a huge turn and flew wildly into a place nearly 90 degrees above the ground. Since it had less than 50 seconds left for it to escape, if it failed to enter the safe zone, Enola Gay would be blown to powder in this huge shock wave. At 8:16 a.m., the detonator detonated, two pieces of uranium 235 immediately merged into one, causing a chain reaction, within 43 seconds, “Death” lowered an altitude of 550 m above Hiroshima. At this time, the people of Hiroshima at the center of the explosion saw a large fireball suddenly rise above the city center, burned to ash by the temperature of more than 6,000 degrees, even to the point of time. Crying and crying can’t help. The bright light blinded thousands of people instantly, and the shockwave following the explosion directly destroyed the entire city. In just a few short seconds, the lives of 70,000 people were taken away by the “god of death”, within a kilometer of the center of the explosion, there was no sign of life, even the buildings were vaporized, dead silence. The fire spread throughout the city, the cries for help echoed throughout the streets, big and small. According to the memories of the survivors of each year, everyone’s facial skin was burned black, hair was no longer there, some people were completely unrecognizable, couldn’t even distinguish which one was the face, which was the head, whose skin was not stripped, hung there, as if cooked. There are also corpses burned to black coals that can be seen everywhere, living people step over corpses, people can’t be people, and demons can’t come out. It is estimated that more than 88,000 Japanese people were killed on the day of the atomic bomb in Hiroshima, the number of Japanese who died from nuclear radiation after the explosion could be even higher. On August 9, just three days after bombing Hiroshima, the Americans repeated the old trick and dropped another atomic bomb on Nagasaki, killing 86,000 people on the spot. After suffering the effects of two atomic bombs, Japan finally submitted a letter of surrender. In this regard, then-US President Truman said: “Only the sound of nuclear explosions can make the Japanese truly listen to submission.”

The security hole exists for more than 3 years, but Intel has not been able to fix it. Photo: CIO Indeed, 3 years have passed, and there is still no end to the vulnerability. Meanwhile, experts from the University of Virginia and the University of California, San Diego, have discovered a new attack method that bypasses all current Specter protections built into the chip. This attack method has the potential to put almost any system – desktops, laptops, cloud servers and smartphones – once again at risk. Revealing Specter ushered in a wave of more powerful attacks, allowing malicious code to directly read passwords, encryption keys, and other valuable information from the computer’s kernel memory. Although chip manufacturers such as Intel, ARM and AMD already know this and combine defenses to reduce the threat from vulnerabilities, the methods have not yielded the desired effect. A Specter attack is capable of tricking the processor into executing instructions along a wrong path, the researchers say. Even though the processor recovers and completes its task correctly, hackers can still access confidential data while the processor goes in the wrong direction. The new attack method exploits what is called a micro-operator buffer (called micro-ops), an on-chip component that breaks machine instructions into simpler instructions and speeds up computation, like a secondary channel to reveal confidential information. Micro-op cache is built into Intel processors, manufactured since 2011. According to researchers at the University of Virginia, Intel’s defense proposal against Specter (called LFENCE) is to place sensitive code in a waiting area until security checks are done and only then the code Only sensitive is allowed to execute. However, research has shown how attackers can steal information through micro-op caching and use it as a secret channel. Although exploiting the Specter vulnerability is very difficult, the researchers say that with computers with a lot of sensitive data, hackers do not mind the difficulty. To protect the system from the new attack, the researchers propose to clear the micro-ops cache. This is a technical solution that comes at the expense of performance benefits. According to the researchers, micro-op caching has some dangerous effects. First, it ignores all caching reduction techniques such as side channels. Second, attacks in this zone go undetected like an existing attack or malware. Third, because the micro-op cache is at the front of the path, prior to execution, Intel’s Specter protections or recommendations to limit cache updates are still compromised. public.

Pierre Curie is a French physicist, a pioneer in the fields of crystallography, magnetism, piezoelectric phenomena and radioactive phenomena. Under the influence of his brother, Pierre Curie’s curiosity about the mysterious world also gradually grew and it was because of this curiosity that he met the bizarre girl Eusapia Palladino, who is said to have can help the dead talk, capable of moving objects at a long distance. Eusapia Palladino. While traveling through Paris, Eusapia Palladino’s special abilities aroused the interest of scientists who believed that the causes of these unusual events could be found. So, more than 10 scientists decided to conduct experiments with Eusapia Palladino, including Pierre Curie and his wife, Marie Curie. Compared to his wife, Pierre was shocked to see these phenomena with his own eyes: he saw the table move on its own, saw strange lights and shadows, even felt a hand. invisible is touching me … Between 1905 and 1908, Eusapia Palladino produced countless strange phenomena in 43 trials. In the end, what conclusions did the scientists reach? In fact, they could not come to any concrete conclusions and there are many who think that Eusapia Palladino is just a talented magician who can pass the eyes of everyone. For his part, Pierre Curie could not say a word because he died in an accident in 1906 before finishing the test. But his notes say: “We attended many of Eusapia Palladino’s séances at the Center for Spiritual Studies. It was indeed very interesting. The four feet of the table slowly lifted by someone. The objects moved themselves. There was a hand. it pinches or caresses you. Flickering ghosts. These phenomena are really inexplicable. ” “During these séances, we have a few attendees. We know these people well, and no one can be an accomplice or help Mrs. Palladino. The only grounds for suspicion. , that this fellow is actually a magician, but how do you explain, when during the process, someone holds her hand, someone holds her hand, and the light is enough for us to see clearly. everything”. So can the dead talk to the living? This problem always hurts in the head of British physicist Sir Oliver Lodge, especially after his son Raymond died on the battlefield during World War I. Sir Oliver Lodge. In order to cross the boundaries of death and communicate with Raymond, Sir Oliver Lodge repeatedly tried different spiritual methods. Over time, a new question arose in his mind: How can it be certain that the message the psychic sends actually comes from a deceased person and not a fabricated message? To get around this problem, Sir Oliver Lodge came up with a suggestion: someone wrote on paper what he wanted to be conveyed by the psychic after death, and sealed it with an envelope. That way, we can verify whether the information transmitted by the psychic is correct or not. And then he actually decided to complete this experiment himself. So after his death, many spiritualists tried to decipher the mysterious rumors after the death of Sir Oliver Lodge. But how the truth is up to now is still a mystery. Sir William Crooks. The British physicist Sir William Crooks is not only an important figure in the history of science, but also an expert in “ghost” photography. He was one of the first photographers to capture “ghosts” on camera. Sir Crooks photographed a female ghost named Katie King, the daughter of an explorer in the 17th century. It is no coincidence that this girl’s ghost may appear in the photo but instead, she is ” summoned “by a young woman named Florence Cook. The witch Katie King. It happened in Florence’s parents’ house: a curtain, behind the curtain, was pulled in front of the door of a hut and then Florence summoned souls to possess them. Moments later, the soul of Kate King dressed in white began to appear, and the curtain slowly lifted … All of which was then thought to be fake, the soul of Kate King was in fact. it was Florence in disguise. But Sir Crooks asserted that the scene he saw was a supernatural phenomenon. However, with all 3 stories mentioned above, can not prove that Western scientists believe in ghosts or mysterious supernatural phenomena? Up to now, there are still many scientists conducting experiments to answer the question of whether the spiritual world really exists, but in reality there is still no answer that is sufficient to prove. this.

Today, according to the accepted features of the 6th generation fighter, the aircraft can be piloted with or without a human presence and although today, experts note. Unmanned version of the Su-57. However, the fact is that Russian fighters can be used in unmanned aircraft (UAV) mode and will most likely be controlled by an artificial intelligence system that enhances the fighter type. Level up to generation 5+ or even to generation 5 ++. The Su-57 fighter developed in 2002 was Russia’s first stealth fighter. (Photo: RIA) For information on the use of drones by Russian Su-57 fighters, military analysts said the Su-57 fighter aircraft will be carried inside and outside the cabin. And development of the cockpit device and the control software program has begun. “A rack is also being built to conduct ground testing of the UAV’s interactive system with fighters and between UAVs in real time using a semi-autonomous simulation system. of course, ”said a source in the military industry. It is known that a fifth generation Su-57 fighter aircraft can house more than 10 reconnaissance and attack UAVs, as well as electronic warfare systems. Currently, work related to the testing of these drones is already underway. However, under the control of fighter aircraft systems, Russian designers will likely execute the plan no sooner than 2024-2025. “The devices in the group operation through safe communication channels will interact with the control complex on the fighter aircraft carrying the UAV and between the UAVs together,” the source explained. Earlier, in the context of the completion of the repair and modernization of the Russian heavy aircraft carrier Admiral Kuznetsov, it emerged that the Russian fleet was preparing to equip the deck of this aircraft carrier with a group of engines. Su-57 fighter jet. A carrier-based version of the fifth generation fighter, moreover, the second version could appear in 1.5-2 years. The Russian designers are actually working on developing a carrier-based version of the fifth generation fighter Su-57, while the development stage is not disclosed, however, the appearance. of the possible carrier version of the Su-57 by 2023. To date, there is no official confirmation of this data, however, the Russian fleet is clearly interested in increasing Admiral Kuznetsov’s aircraft carrier’s combat capabilities through the use of technology fighters. high – even a current version of the Su-57 alone enough to defend against an entire group of enemy carrier attacks. The fifth-generation fighter Su-57 is considered Russia’s most high-tech fighter, and although the mass production of this fighter faces some difficulties, its prospects are still very high. By the end of 2020, the first stealth fighter Su-57 in the mass production batch with ID number 01 was staffed for the Southern Military Region and operated at the Novosibirsk base. Sources in the Russian defense industry said that four more Su-57 will be delivered to the Russian Aerospace Forces in 2021. Currently Russia has only one mass-produced variant of the Su-57, although it claims to be able to develop several variants from the original. Russia for the first time promoted a second version, the Su-57E, in March 2019 that could be used for export.

The convoy passed through Tan Uyen, Lai Chau tea hill on the journey “across the Northwest”. Photo | MAI TRUNG KIEN Sustainable and environmentally responsible tourism becomes the new standard of top priority. Opt for road travel and use private transportation instead of public transport. Explore the destination in small groups you know instead of in large groups. Find out about the immense natural scenery instead of choosing enclosed spaces … There are a series of fundamental changes in the tourists’ mindset that the World Tourism Organization (UNWTO) has forecasted, as the ghost of Covid-19 is still casting a shadow over the global smokeless industry. Therefore, the caravan – a rare type meeting most of the above factors will officially “take the throne” in the context of Vietnamese tourism trying to find ways to quickly recover from the pandemic. Caravan – an unforgettable experience for the romantic traveler Caravan is a term for a group of travelers traveling together by road, traveling by private vehicle, most commonly self-driving cars. Caravan appeared in the world from about two decades ago. Although it has not been imported to Vietnam for a long time, but caravan quickly attracted the attention and love of the enthusiastic community “traveling” by the number of people owning private cars, passionate about exploring and wanting to experience “silk steering. “On new, dangerous but beautiful roads that are becoming more and more crowded. A survey on Booking.com shows that the tastes of Vietnamese tourists have changed quite a bit in the context of a complicated pandemic. Accordingly, 75% think that keeping safe while traveling is the number one priority, 42% choose alternative destinations to avoid crowded areas, 50% ignore public transport to avoid traveling together. with many strangers. Therefore, according to Mr. Truong Duc Hai, Chairman of the Board of Directors of Vien Dong Pearl Company (specializing in organizing this special tour in Ho Chi Minh City), “the caravan model is more and more popular after the pandemic because both safe in health, ensuring disease prevention and fighting, and suitable for short-term travel trends, close distances by small groups and families “. Covid-19 is also the warning that Mother Nature sends to humans, when the environmental abuse, the environment has gradually become out of control. Therefore, trauma, trauma, loss after the pandemic has caused visitors to put higher requirements on the itinerary to experience, no longer purely play and relax, but have to find things of value, meaning and possibility. contribute positively to the community, preserve the landscape at the destination. With small cars, the caravan journey easily takes visitors to remote, dangerous but new and attractive destinations that large passenger cars cannot reach. There, guests will have different experiences about the lives of indigenous residents, learn about the quintessence of history – culture – cuisine – community activities … in strange lands, ethnic minorities are living along the S-shaped strip of land. In addition, this is an opportunity for members to combine tourism activities with charity programs – market research – investment promotion. , promote … practical, meaningful and effective. Participating in a caravan journey, visitors have the opportunity to drive by themselves, with a professional guide to share detailed and attractive destination information. Safety is absolutely guaranteed, when the tour has a guided car and tailgate with the libero supporting media and technology (if the group has more than 15 vehicles). Mr. Phung Gia Tuan, Caravan Vietnam Company, explained: “In order to be safe, the caravan must know how to distribute and arrange vehicles properly. For example, drivers who are young, weak and unfamiliar with the terrain must be sorted into the car. The middle position, which is attached to the front and back cover for peace of mind to move and not to break the link between the vehicles together.The team leader will adjust the appropriate distance between members depending on the terrain, weather or the level of danger of each downhill road. Vehicles are warranted, maintained and checked thoroughly before rolling. ” In addition, the organizer must prepare vehicle repair equipment, basic human first aid and necessary support plans when an incident arises. The pre-station process must be done periodically, to capture any changes from roads to local traffic arrangement regulations on the itinerary to have full information for tourists or adjust the route accordingly. safety. Tourism model towards sustainable development Restoring responsible tourism, taking sustainable tourism development as a direction. Develop different tourism products with economic efficiency criteria – local tourism development – preserve and promote historical cultural values ​​- join hands to protect the environment. That is the goal that the Hanoi Travel Association and the VGREEN Sustainable Tourism Club aim to, when shaking hands with the National Museum of History to design a series of VGREEN Caravan programs, which are recently launched. Attractive tours always have a starting point from the museum campus, where members are provided with initial historical knowledge and then have the opportunity to dissect each layer in the historical sedimentary bed of thousands the year of building and defending the country of the Vietnamese people along the way. Taking history as a starting point, making it a thread throughout the journey of discovery, this promising handshake demonstrates Covid-19’s “flexible – adaptive and effective” effort to overcome storms. VISTA Hanoi member travel businesses. An impressive start and receiving positive reviews from travelers was the caravan tour Northwest – Flowering season . Not only conquering the famous winding mountain passes such as Khau Pha – Pha Din – O Quy Ho or admiring the interesting caves like Pu Sam Cap – Tien Son, visitors also experience paragliding on not in Tam Duong, enjoy the scenery of Da river lake in Quynh Nhai or experience the unique cultural colors of the Northwest ethnic groups. On the way, they were also transformed into a soldier – the citizen of the caravan, carrying food at the foot of the legendary Pha Din pass of the historic Dien Bien Phu campaign in the past. In particular, they also visited Xom Trai cave dating back to 17 thousand years and is a typical archaeological site of Hoa Binh culture, participating in the prehistoric fashion contest right at the cradle of culture. This famous ancient. There are also products Journey to explore land in Son Nam bring the drivers back to Nam Dinh land to enjoy the architecture of the beautiful ancient villages, immerse themselves in the quiet space of the old villages, admire the beauty of the churches, find out about the beliefs of worship. Sample with the ceremony of singing chau van – serving dong. Welcoming the anniversary of Hung Vuong’s death anniversary, the highlight of Return to the sacred source of the ancestral land experience the night tour at the historic Hung Temple, where visitors can respectfully dedicate incense to the ancestors and practice Hung Vuong Worship Ceremony, representative of the Intangible Cultural Heritage of mankind. Mr. Phung Quang Thang, Vice President of VISTA cum President of VGREEN Club said: “Sustainable and responsible tourism helps businesses to participate in improving their image, better business, minimizing risks from objective impact This type of product has been responded by both domestic and foreign tourists, especially in the current period.With the locality that owns the destination, people are directly involved in exploiting the product, have the opportunity to eradicate hunger and reduce poverty thanks to a sustainable income source and thereby develop a true community-based tourism model “. The list of VGREEN “labeled” caravan tours is still very long, with many interesting routes inviting “travelers” to go. Not only linking travel businesses, in the direction of “if you want to go far, you have to go together”, the club also implements a series of professional training activities for the implementation team, such as organizing the workshop “Tour operation skills. Caravan “or provides specialized skills in ensuring safety, preventing and combating epidemics, protecting relics – heritage, reducing plastic waste, supporting communities in tourism … All to welcome, build building and developing an optimal tourism model with unlimited potential in the “post-Covid-19” recovery phase.
