Demonstration of the incredible Coanda effect with the example of a ball that does not fall as it 'sticks' to the lower part of the air stream. Physics is a kind of magic indeed!

Skydiver & Raindrop An increase in the resistance to motion along with an increase in velocity causes a steady, regular motion of a body as it falls from a great height in a liquid or gas (e.g. in the atmosphere). Thus, a skydiver can gain speed up to 50 m/s before opening the parachute, and raindrops, depending on their size, reach speeds from 2 to 7 m/s.

Paper airplane and aerodynamics.

People: "All these robots are harmless, the battery runs down in five minutes, why be afraid of them?" Scientists: "The bipedal robot ran five kilometers for the first time – it took 53 minutes and one battery charge to do it" 🤖😳 The Cassie robot was created by students at Oregon State University with one million dollars in grants from the Defense Advanced Research Projects Agency (DARPA) in 2017. The bipedal robot is controlled by a neural network using deep machine learning with reinforcement.

How to make the simplest unipolar motor

Such a beauty appears if you water the screw with ferromagnetic liquid (it is strongly polarizing in the presence of a magnetic field liquid, which contains ferromagnetic nanoparticles).

Barium Sulfate Used In LEGO Parts If a child swallows a LEGO part, it will be visible on an X-ray due to this compound. However, sulfate was abandoned in 1996 as it made the plastic brittle.

Here is a collection of real elements from the Mendeleev’s Periodic Table! Wonder about how airtight this thing is... After all, it contains elements that can be harmful to a person.

Static Discharge Imagine the situation; someone invites you to visit. You come to the door on time, wipe your feet on the mat thoroughly, then touch the brass door handle... and that's when you feel a slight impact. It's a static discharge. Why does this happen? After you had wiped your feet on the mat, your body received a negative electrical charge. Then you touched a negatively charged hand to a positively charged metal object (a door handle in our case) and the electrons transferred from your hand to that object. Such an instantaneous transfer of electrons is called a static discharge. It was precisely at the moment you felt a slight electric shock.

CyberDog: Xiaomi First Robotic Dog Does your dog know how to do a backflip? 🤖 Well, Xiaomi dog can. Jetson Xavier NX module from Nvidia, containing 384 CUDA cores, 48 tensor cores, six Carmel processors and two specialized deep learning cores, became the computing center of the robot. The module collects and processes information from 11 sensors. It uses specially designed Xiaomi servos to move, enabling it not only to walk, but also to do backflips and other tricks. In fact, the machine moves at 3.2 meters per second and weighs 3 kilograms. Xiaomi reports that the robot can follow its owner like a real dog. The device also recognizes faces. By the way, the CyberDog can be controlled by voice or through a smartphone app. What do you think, whether the robot is capable of fully replacing a real animal?
