The molecule model

Much in physics can be simulated, thereby greatly simplifying and accelerating the mastery of the subject. The wire model of a molecule with spheres shows what the molecule consists of, but does not hold back the phenomena occurring inside it under the interaction of various forces...

How to transfer energy?

From the school bench, everyone knows that a lot of energy is lost in the wires of power lines. In addition, the shortcomings of this method can be attributed energy transfer: the need for a large number of copper, the high cost of laying the power line, the need to install huge supports...

Beyond the beam of light...

A beam of light, passing the boundary of two media, is usually split into two rays - reflected and refracted. An elegant regularity was also known to the ancient Greek scientist Ptolemy: the sine of the angle of refraction is many times greater than the sine of the angle of incidence, the number of times the refractive index of the first medium is greater...

Electrons in a magnetic field

If you have already spent your old TV, then each of us is able to conduct a simple experiment with electrons. After all, in the tube of the television it is the electrons striking the screen with a kinescope, causing a glow. Take a permanent magnet stronger, lift its pole to the screen. The image on the screen will turn into a spiral resembling a galaxy...

The magnetism of the Earth

In 1891, the English scientist Schuster tried to explain the magnetism of the Earth by rotating it around the axis. A lot of work on this hypothesis was given by the well-known physicist PN Lebedev. He assumed that, under the influence of the centrifugal force, the electrons in the atoms shift toward the surface of the Earth...

The melt water

The properties of melt water have long astonished the scientific world. The ideas of the Kazan scientists, put forward by them in the 20th century, which in their own way explain the mystery of thawed water, are worthy of attention. Chickens and piglets were given melt water. They, surprisingly, quickly grew. What physical...
