RUSSIAN SCIENTISTS

Russia gave the world many outstanding scientists. Russian scientists made a great contribution to the world science.

V.V. Petrov (176l-1834), the follower of Lomonosov in studying electricity, is called a pioneer of the world electrical engineering. He was experimenting with electricity and made many discoveries of great importance. He published a great number of articles on electricity. The electric arc discovered by Petrov became the first source of electric lighting. Petrov discovered the possibility of getting metals out of ores by means of electricity.

Academician E.Kh. Lenz (1804-1875) is one of the most prominent Russian physicists. He discovered the law of heat generation by an electric current and the law defining the direction of an induced electric current.

P.M. Yablochkov (1847-1894) is a prominent inventor and designer. He did much for using alternating current. He is famous for inventing the “Yablochkov candle” (arc lamp) known abroad under the name of the “Russian Light”.

A.S. Popov (1859-1906) is known for his invention of a radio. After demonstrating his device Popov was offered a lot of money for the commercial use of the radio abroad. But he was a true Russian patriot, he refused to leave Russia. He said that all his knowledge and his achievements belonged to his native land.

Dolivo-Dobrovolsky (1862-1919) is a Russian engineer. He is the inventor of a three-phase generator and a three-phase transformer. He proposed a number of original designs of measuring instruments.

We know many other names of great Russian scientists and we are proud of them.

Lobachevsky’s non-Euclidean geometry brought about a revolution in science. Mendeleev discovered the periodic law of elements. The world’s first photoelectric cell was built by Stoletov. Lebedev succeeded in measuring the pressure of light experimentally. Zhukovsky and Chaplygin worked out the theory of flight and the principles of aerodynamics. Vernadsky laid the foundations of geochemistry – the science of chemical elements.

The first atomic power station and Yuri Gagarin’s flight into space, lasers, semiconductors and many other achievements of modern science and technology have been created and discovered by such prominent Russian scientists as Tsiolkovsky and Kurchatov, Keldysh and Korolyov, Basov and Prokhorov and many others.
