A. S. Popov - inventor of radio, who can be proud of our country. He first began studying the electromagnetic waves, and even was a teacher relevant courses for officers. It is Popov found the practical application of electrodynam, open Hertz. First his experiments, the scientist began with the repetition of the experiments of the famous discoverer. But with time Popov invented his own, more sensitive and reliable way to record the electromagnetic waves. The device which he invented for this purpose was called a "coherer", and looked like a tube of glass, filled with metal shavings. Inside it are placed two electrodes. On the interaction produced by them is electricity and metal was the whole principle of the invention. However, to enhance the effect, I had to periodically shake the tube to sawdust was not accustomed to drinking among themselves. To not constantly do this manually, Popov began to use a bell device. Subsequently, there is a need to strengthen the action of the coherer. Scientist has grounded one of the electrodes, and the other raised and attached to the span wire. Thus was invented the first antenna to wirelessly receive. Current appliances little resemblance to the invention of the scientist, but the principle of their action is virtually not changed since then. With the exception of the method of controlling the energy sources now used for such purposes semiconductor devices.

Few people know that the famous inventor of radio Popov is considered to be a pioneer only with us. In America, for example, call a different name - G. Marconi. The latter really was the father of radio, but in a commercial sense. He first started the production of radios and captured most of the market, while our domestic scientist worked more carefully and not jump to output "raw" invention into circulation for public use. It is obvious that Popov, in contrast to the enterprising colleagues, persecuted not for personal commercial purpose. The scientist wanted to make the radio available to put his invention at the service of all humanity. The debate on the topic of superiority inventors do not stop for more than a century. Although, in fact, rightly be considered a true pioneer in this area of Heinrich Hertz, who discovered electromagnetic waves and method of their transfer to a distance.

The Inventor of radio officially became one in 1895. As for dates, here called the two numbers. It would be correct to say that a significant event has occurred the seventh of may, new style. Especially considering that this number referred to many textbooks and encyclopedias. On this day, our radio inventor showed his creation to fellow scientists at a meeting in St. Petersburg. It was the first public signal transmission distance of 60 meters. Since the seventh of may each year is celebrated in Russia as radio Day, a celebration for everyone who works in the communications industries.

Popov - inventor of radio, whose works were based in the work of military engineers. Those people who, first of all, I appreciate the speed in achieving results, and the quality and reliability of the finished invention. The transmission of signals in the military sector has always been important and in some degree a priority, which further increased the value of the work of our scientist. Initially, however, the range of the signal left much to be desired. But Popov was always working on this, improving his invention. The first long-distance radio transmission was able to overcome the threshold of 250 meters. Soon, after persistent manipulation, the scientist has made even greater strides - 600 meters. During the maneuvers, held by the black sea fleet, the scientist continued the experiment to the public. The results for the time were stunning 20 km away. This demonstration was held in 1899. And two years later, Popov was able to bring his invention to the transmission range of radio signals at 150 km. it Was found that to receive the signal and possibly by telephone. Around the same time, thanks to the work of the scientist was found by a fishermen stranded on an ice floe in the Gulf of Finland. So, with the salvation of men, began the practical work wonderful inventions Popov. Soon began the introduction of radio communications in all spheres of life, including for military purposes - for the Navy and the Russian army.
