Electrolysis of tin chloride to form metal.

Variation of the frequency of the oscillating circuit depending on the magnetic properties of the material.

Brachistochrone is a curve lying in the plane between point A and lower point B, where B is not directly under A.

Thus an object slides without friction under the action of a homogeneous gravitational field to a given end point in the shortest possible time.

Heating metal powder in pure oxygen.

Jet engine in a cross-section

A turbojet engine is a gas turbine engine where the chemical energy of fuel is converted into the kinetic energy of gas jets flowing from the jet nozzle.

Extraction of spent nuclear fuel from a nuclear reactor.

The blue glow that can be observed is called Vavilov-Cherenkov radiation.

It is the emission of light by an electrically charged particle when it moves in the medium at a speed exceeding the phase velocity of light in this medium.

How is aurora borealis formed?

The Earth's magnetosphere captures charged particles of the solar wind and as a result aurora borealis is formed at the poles.

Thermal drilling of metal

Thermal drilling technology is based on the principle of plastic deformation of metal. In the process of impacting a thin-walled piece with a drill bit, due to the friction of the tool tip against the metal, the latter is plastically deformed and a through hole is formed.

The effect of resonant frequencies

The frequency-selective response of an oscillating system to a periodic external action, which manifests itself in a sharp increase in the amplitude of the stationary oscillations when the frequency of the external action coincides with certain values characteristic of the system.

Copper is non-magnetic, though it creates resistance in the presence of a strong magnetic field, causing the magnet to halt for a moment before it even touches the copper.

The spark in the macroscope.

Diffusion is the nonequilibrium process of moving a substance from an area of high concentration to one of low concentration. Leading to spontaneous equalization of concentrations throughout the occupied volume.

Fire + solder PIC-60 + water

Magnetic levitation in all its glory.

Certain materials feature a shape memory effect — after deformation, they return to their original shape when heated.

Such a property is due to its superelasticity. Titanium nickelide, as an example, has this quality. Similar materials are quite practical and can be used in a wide range of areas, from space to medicine.

The Painful Magic of High Voltage Levitation

And keep in mind, you have to be extremely careful with electricity.

Airborne infrared display, facilitating navigation at night and during precipitation.

Rare footage of "blue jets" captured from the space station

Blue jets are cone-shaped flashes of light spraying upward from the top of a thundercloud.

Experiments in weightlessness

Induction heating

A method of non-contact heating with high frequency and high magnitude currents of electrically conductive materials.
