ASPopov - inventor of the radio, which can be proud of our country.He first began to study the electromagnetic waves, and even the teacher was relevant courses for officers.Popov found a practical application elektrovolnam open Hertz.The first scientist started his experiments with repetition of experiments known discoverer.But over time, Popov invented a more sensitive and reliable way to detect electromagnetic waves.The device, which he invented for this purpose, has been named "coherer" and looked like a glass tube filled with metal shavings.Inside it are placed two electrodes.On the interaction of electricity generated and metal lay the whole principle of the invention.However, to enhance the effect had to periodically shake the tube to filings are not soldered together.To consistently produce this process manually, ASPopov became CONTACT-use device.Subsequently, there was a need to strengthen the action of the coherer.Scientific ground one of the electrodes, and the second raised and attached to a piece of wire.Thus it was invented the first antenna for wireless reception.Current electrical slightly reminiscent of the invention is a scientist, but the principle of their action has not changed since then.Except for a method of controlling energy sources are now used for purposes such semiconductor devices.
Few people know that the famous inventor of radio Popov, considered a pioneer only with us.In America, for example, is called a different name - G. Marconi.Last he was really the father of radio, but in a commercial sense.He first started the production of radio and captured most of the market, while our, Russian scientist worked more carefully and slowly withdraw "raw" invention in the circulation for public use.Obviously, Popov, unlike the adventurous colleagues, pursued not personal sales goals.The scientist wanted to do radio available, to put his invention to the service of mankind.The debate on the subject championship inventors do not stop for more than a century.Although, in fact, rightly be considered a true pioneer in the field of Heinrich Hertz, who discovered electromagnetic waves and their method of transmission distance.
inventor of radio became officially established in 1895.As for the date, here called the two numbers.It would be correct to say that a significant event has occurred seventh of May, new style.The more that this number is called many textbooks and encyclopedias.On this day, our inventor of the radio for the first time showed their offspring fellow scientists at a meeting in St. Petersburg.Then it was made the first public signal transmission distance of 60 meters.Since May 7 annually celebrated in Russia as Day of Radio, a holiday for everyone who works in the communications industry.
Popov - inventor of radio, whose works were based in his work military engineers.Those people who, first of all, do not appreciate the speed in achieving results, and the quality and reliability of the final claims.Signaling in the military industry has always been important and to some extent a priority, which further increases the value of the work of our scientists.Initially, however, the range of the signal is poor.But ASPopov is constantly working on it, improving his invention.First broadcast far been able to overcome the threshold of 250 meters.Soon after persistent manipulation, the scientist has achieved even greater success - 600 meters.During the maneuvers, conducted the Black Sea Fleet, the scientist conducted an experiment once again to the public.Results for the time were stunning - 20 km.This demonstration was carried out in 1899.But after two years, Popov was able to bring his invention to the radio transmission range of 150 km.It was found that the receive signal possible and by telephone.Around the same time, thanks to the work of the scientist were found fishermen lost on an ice floe in the Gulf of Finland.So, with the salvation of men, began the practical work of a remarkable invention Popov.Soon began the introduction of radio communication equipment in all spheres of life, including for military purposes - for the fleet and army of Russia.
