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.

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.

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.

In order to blow out plastic containers, you need a compressor. It is the compressor that generates the pressure by which the air jet is delivered.

Wave Optics

Light waves are regarded by their nature as electromagnetic waves, possessing all their properties.

Kittens enjoy physics too 😽

Sound pressure is the variable overpressure that occurs in an elastic medium when a sound wave passes through it.

Polarization of light is a property of light, resulting in the vectors of electric and magnetic fields of light waves are oriented in a plane parallel to the plane in which light propagates.

It occurs when light is refracted, reflected, or passes through an anisotropic medium.
