The water pressure in the depths of the ocean

There are legends that the ships sunk in the ocean do not lie on the bottom, but hang at some depth, traveling together with ocean currents. Is this fair? The water pressure in the depths of the ocean really reaches enormous values. At a depth of 10 m, water is pressurized with a force of 10H per 1 cm2 immersed body, at a depth of 100 m - 0,1 kN, 1000 m - 1 kN, etc. At the depth of the Mariana Trench - 11,5 km...

Magnetic monopole

Magnetic monopole

We all know that the magnet should have two poles - the north and the south. A magnet with a single pole, or, as it is called, a monopole, it turns out, does not contradict science at all. In 1931, the outstanding physicist P. Dirac (1902-1984) mathematically proved the possibility of the existence of a magnetic monopole - a particle with a magnetic charge...

Henri Becquerel

Scientific discoveries are designed to change the world for the better. One of these discoveries was the discovery of the radioactivity of certain chemical elements, which served as the basis for the creation of both super-powerful weapons and powerful sources of energy. So who was the first to open these deadly rays? It was Antoine Henri Becquerel...

Magnetic suspension

What is a magnetic suspension? To hang massive objects you need a magnetic field of monstrous tension. In 1939, the German scientist W. Braunbek used an electromagnet for this, otherwise he would not be able to obtain such a high magnetic field strength with the help of permanent magnets of the time. But the electromagnet required constant current make-up...

Electromachines

What is electromachines? These are electromotors, which convert electric current into mechanical motion. In addition, the electric machines include generators, performing the reverse task - the transformation of mechanical motion into an electric current. The world's first electric motor was created by Faraday...

Color of the sky

On our website you could already read what color is. But how many different colors are there, what makes the things around us colored? And scientific knowledge on many such questions can already answer. For example, explain the color of the sky. First, we need to mention the great Isaac Newton, who observed the decomposition...
