A. Popov, a Russian physicist, was the first person to demonstrate the practical application of electromagnetic radio waves. Beginning in the early 1890s he continued the experiments of other radio pioneers, such as Heinrich Hertz, and in 1894 he built his first radio receiver, a version of the coherer. Further refined as a lightning detector, it was presented to the Russian Physical and Chemical Society on May 7th, 1895 — the day has been celebrated in Russia as Radio Day. In 1896, he demonstrated transmission of radio waves between different campus buildings in Saint Petersburg. He demonstrated ship-to-shore communication over a distance of 6 miles in 1898 and 30 miles in 1899. However, it is Guglielmo Marconi, an Italian inventor, who is believed to be the father of long distance radio transmission in Europe and the USA.
B. Grabovsky and I. Belyansky were Soviet engineers who invented the a fully electronic TV transmitting in 1928. Even earlier, in 1923, it was V. Zworykin, a pioneer of television technology, who invented a television transmitting and receiving system employing cathode ray tubes.
G. Kotelnikov was the Russian-Soviet inventor of the knapsack parachute he first introduced in 1911 (first in the hard casing and then in the soft pack), and braking parachute.
Russian scientist A. Poniatoff who emigrated to the United States was the first to design the videotape recorder.
The first artificial satellite was launched in the Soviet Union in 1957. Called ‘Sputnik-1′, it was designed by S. Korolev and his team.
Nuclear power plant.
The first nuclear power plant was put into operation in the city of Obninsk in 1954. At the same time, the notion of ‘nuclear energy’ appeared.
There are 10 atomic ice-breakers in the world and all of them were designed and built in the USSR and Russia.
