Illustration. For ants and small animals, the resistance of the air helps them a lot and makes their falling velocity very slow, sometimes their acceleration is negative (due to the wind blowing up). Thus, ants are almost unharmed when falling from the roofs of high-rise buildings. All objects falling through the air have terminal velocities that depend on their size, shape, and mass. The terminal velocity of an ant (6.4 km/h, according to the physics department of the University of Illinois) would be vastly different from the terminal velocity of a human (about 200 km/h). “For rats and any small animal, there’s really no danger. You can drop a rat into a minehole nearly 1,000 meters deep and when it hits the bottom, it’ll be slightly stunned and run away. , provided that the ground is fairly soft.The air resistance acting on a moving object is proportional to its surface.If the length, width and height of an animal are divided by 10, respectively, the mass is its mass is reduced by 1000 times while the surface area is reduced by only 100. Therefore, the air resistance for small animals is usually 10 times higher than the driving force. Force isn’t usually a problem for an insect, it can be free-falling without danger, with the ability to grip.” Michael Kaspari is an ecologist at the University of Oklahoma (USA) who has studied the aerial activities of wingless ants. Research shows that when ants are facing a predator, they will jump right into the air from tall tree branches and use their legs to control the direction of flight to reach the tree trunk. The longer hind legs will help the ants glide through the air, helping them avoid falling into places they consider dangerous. With this ability, it is possible that the ant has found a way to cling somewhere before it falls to the ground, but whether or not the ant does, the ant will not die if it hits the ground. The most ancient creature that still exists to this day It is said that the earth currently has 10 million billion ants, despite the fact that they are killed a lot every day. According to the biological kingdom, it is estimated that ants account for 15-20% of the total number of animals living on land. Ants are animals belonging to the order of membranes, the class of insects. Scientist Corrie Moreau and French colleagues published a study showing that ants appeared between 140 and 170 million years ago. That means they are the most ancient creatures that still exist to this day, despite the violent fluctuations of the earth. Since then, it has been found that ants have a very high ability to survive in all weather conditions. Such survivability is endowed by nature, for they show no sign of changing accordingly. Which means it’s very likely that an ant 170 million years ago and an ant today would be no different. It is thought that the earth exists about 20,000 different species, with 4,500 families. They are present everywhere on earth. Even the extremely cold places are the poles of the earth, or the hot center of the equator. Ants come in many varieties, but the color is usually just red or black. Especially, there are new species mixed with white color. Ants are gregarious species, with a rather distinct social organization. Each ant nest has an average of about 100,000 children in a colony with a single mother (Christian ants can live up to 30 years). Here, there is something like the organization of a swarm life of bees. The vast majority of ants in the colony are worker ants (who only live for 1-2 years) – likened to the hardest workers on earth. The job of worker ants is to take care of the queen, incubate eggs, transfer eggs, raise baby ants, build burrows, find food, guard … Not many people know that all worker ants are female, but their reproductive organs are not fully developed, so they can never become a god, but are forever just “cool” feet from birth. until death. Ants are considered to be the strongest species because they can carry food 10 times heavier than themselves. But to transport that heavy amount of food, they must use collective strength in coordination. Together they carry the food they earn very easily, when thousands of them work together. Ants are everywhere, everyone can see them or be bitten by them, but few people know that they also have positive effects. The Masai people of eastern Africa have a habit of using ants as a tool to heal wounds. When a member of the tribe is injured, they will catch a few large ants in the swarm of “army ants” so that they bite on both sides of the wound, then remove the ant body, leaving only the ant head on the wound. Since then the wound does not bleed and heals quickly. And interesting things about ants Ants are animals with a fairly hygienic life. Specifically, the handling of dead animals. When one ant dies, the other ants in the colony will together carry the dead ant out of the nest, with the sole purpose of keeping it clean and avoiding infection or disease spread. The workers will take care of the carrying, under the command of an ant that is supposed to be in charge of the burial of the colony. It is also surprising to learn that ants are insects with very advanced organizational systems. Along with the Lord ant, worker ant, and burial commander ant, there are also ‘teacher ants’ Born, in order to have the necessary skills, they undergo a learning process under the guidance of “teachers”. The “teacher” ants in the nest will teach the younger ants to do the necessary work. In case the “student” learns slowly and “fails” in the test, they will be transferred to another job that requires less skill. Not only know how to find termites, but ants also know how to “livestock” to create food reserves. They feed on insects such as aphids and caterpillars to obtain the sweet substance secreted by these insects. When it’s time to harvest the sweetener from the insect swarm, the ants “milk” using their antennae. It is very interesting to know that ants bring with them the insects they nourished when they move to a new area. It’s no different than people taking livestock with them to more verdant places. People have talked about the extraordinary in the world of ants. They have no ears but perceive sound from ground vibrations, through sensitive sensors on the pins. They have the ability to exist to the point of fantasy despite the harshness of weather and climate. Therefore, ants are also one of the first creatures on earth to be sent into space by humans in an experiment to conquer the sky. Ants have poor eyesight, but they often use the earth’s magnetic field to navigate. They are considered the most intelligent insects when in the small head of ants there are more than 250,000 brain cells. As industrious animals, ants are also said to be “excellent athletes”. If an ant were about the same size as a human, they could run at an average speed of 55 km/h without ever getting tired. They are also able to lift an object 50 times its own weight with extraordinary strength.

Facebook’s WhatsApp messaging app icon. Photo: AFP/VNA MEITy’s new rules require major social media platforms like WhatsApp to “trace” the origin of specific messages sent on the messaging service. However, according to a WhatsApp spokesperson, asking messaging apps to trace chats is equivalent to asking WhatsApp to track every single message sent on the app. This would break end-to-end encryption and fundamentally compromise user privacy. The spokesperson stressed that along with civil society and experts around the world, WhatsApp has always opposed requests to violate user privacy, but the application is owned by this social network Facebook. We will also continue to work with the Government of India to find practical solutions to keep everyone safe, including responding to valid legal requests for the information WhatsApp makes available. Earlier, the press reported that social media platforms such as Facebook, WhatsApp, Google and Twitter could face legal action in India if they do not comply with a new regulation by the government to strengthen control. control of intermediary platforms, effective May 26. Failure to comply with the above provisions will result in the social media networks being stripped of their intermediary platform status and immunity and will face criminal action under Indian law. The above regulations also require social media companies to appoint a resident grievance officer, regulatory compliance officer and basic contact person, as well as to disclose detailed information about the company. details of these people on their website, along with physical contact addresses. The regulation also requires traceability of the originator of the message and includes a provision for voluntary verification as a way to establish user identity.

Apple AirTag is actually quite small and its size is only close to the bottle cap. This product has a simple front in case you didn’t choose emoji engraving for free and comes with the Apple logo on the back. “Apple Apples” has equipped AirTag with IP67 water and dust resistance so you can attach it to your pocket or even your pet without worrying about the accessory being damaged in bad weather. . Apple AirTag even has a small speaker inside so it can alert you in case you can’t find your stuff. This accessory comes with a battery life of “over a year” and users can replace it easily. The back of the AirTag is designed to be slightly protruding, where you can replace its standard coin cell battery. As Apple describes it, the AirTag setup is “miraculous”. This accessory will automatically detect your iPhone and display the same setup screen as the AirPods. You just need to name it or set a default like “Key” or “Jacket” and the AirTag tag will start showing up in the “item” section of the Find My app. Tracking accuracy AirTag uses Apple’s U1 chip, found in the iPhone 11 and iPhone 12 series, to determine the exact location. Using the Ultra WideBand technology and the U1 chip, the AirTag can accurately measure their distance from the iPhone and return the exact location. When you tap the AirTag in the Find My app, it uses input from the camera, ARKit, accelerometer, and gyroscope, then guides the user to the AirTag using a negative feedback combination. bar, touch and image. Apple has also added support for accessibility features to AirTag. For people who are blind or have low vision, the VoiceOver feature can be used, which will provide directions such as “AirTag is 9 feet left from you”. Find My Network Apple introduced its Find My Network to third-party accessory manufacturers earlier this month, and it now says “is approaching one billion of Apple’s Find My Network devices”. It is known that AirTag relies on Bluetooth and U1 chip to return location to the user. Therefore, if the accessory is detached from the user, it sends an anonymous signal to surrounding Apple devices. AirTag will then forward its own location, via the nearest Apple device, to its owner in the background, privately. Lost mode If you lose your AirTag and cannot find its location, you can put AirTag in “Lost Mode”. This will create a trigger in Apple’s Find My Network, and in the event an Apple device gets close to your AirTag, it will forward the location of this accessory (private) to your iPhone. If an AirTag is in “Lost Mode” and is found by someone, a user can simply touch the AirTag on an NFC-enabled device (not necessarily an iPhone) and it will automatically open a web page, where details will be shown such as phone number of the lost person. Accessories Apple also released a number of accessories for AirTag. This product does not have a magnetic back or designed to attach to the user’s object, so it will depend on accessories to do that. Apple says users can ditch the AirTag for a bag or purse, and it still works fine. But for objects like keys, it must be kept in a special kind of lock. Apple has released a number of first-party accessories for the device, including Polyurethane Loop, Leather Loop, Leather Key, and some special edition Hermès accessories. The Polyurethane ring costs $ 29 (around 670K), the leather key ring costs $ 35 (around 800K), and the leather bracelet costs $ 39 (about 900K). Third-party accessory manufacturers will also roll out a number of accessories for AirTag in the coming months. Easy to replace battery AirTag comes with a battery that can be easily replaced. Apple says that the AirTag will perform well for “more than a year,” after which users will have to replace its batteries. This accessory uses a standard CR2032 coin cell battery, which can be easily replaced by removing its back cover. Privacy AirTag does not store location data on the device. It only forwards a signal to the nearest Apple device, which is then used to locate the AirTag. Apple says that data is kept confidential and communication with Find My Network is end-to-end encrypted. AirTag also comes with a host of other security features. If an AirTag detects that it is being used to track an unwanted location, it will stop forwarding that location to the user. If separated from its owner for too long, the AirTag will play a sound when someone moves to attract attention. AirTag accessories will be sold for a starting price of 29 USD (about 670K) and you can buy 4 combo for 99 USD (about 2.3 million VND). It’s available for pre-order starting April 23, and will hit retail stores April 30. In Vietnam, the expected list price of Apple AirTag is about 790K. Ceiling paint According to S-FORUM

All objects falling into the air have terminal velocities depending on their size, shape and mass. The terminal velocity of an ant (6.4 km / h, according to the physics department of the University of Illinois) will be much different from the human terminal velocity (about 200 km / h). “For rats and any small animal, there’s really nothing dangerous. You can drop a mouse into a mine nearly 1,000 meters deep and when it hits the bottom, it gets dizzy and runs away. , provided that the ground is quite soft The air resistance acting on the moving object is proportional to the surface of the object.If the length, width and height of an animal are divided by 10, then the mass. Its amount is reduced by 1000 times while the surface area is reduced by only 100 times, so the air resistance for small animals is usually 10 times higher than the actuation force. Force is usually not an issue for insects, it can fall freely without danger, with the ability to cling. ” Michael Kaspari is an ecologist at the University of Oklahoma (USA), who has studied the aerial activities of wingless ants. Research shows that when ants are confronted with a predator, they jump in the air from tall branches and use their legs to steer their flight to the tree.
