Tamer radio — Popov

MARCH 16, 1859 in the village. Turinskie Mines Verkhotursk district of the Perm province (now Yekaterinburg Krasnotur’insk region) in the priest’s family born Alexander Stepanovich Popov, physicist and electrical engineer, inventor of the radio.

May 7 (April 25, Old Style) entered the history of world science and technology as the birthday of the radio. It was on this day in 1895 at a meeting of the Russian Physical and Chemical Society Russian physicist Alexander Stepanovich Popov made a presentation and demonstration he created the world’s first radio.

12 (24) March 1896 at a meeting of the Russian Physical and Chemical Society Popov demonstrated the transmission of words on the wireless telegraph.

Popov did not make secret of his invention, described it in the press has repeatedly reported about it at meetings of scientific societies.

In the early 1896 appears a detailed description thereof, while the patent application Marconi contained receiving device, in detail similar to device Popov was made only in June 1897 while Popov successfully conducted experiments at sea. It was possible to make radio contact between the shore and the ship at a distance of over 3 kilometers and the distance between the ships of more than 5 kilometers. Radiopereklichka was between ships with the portentous title: "Russia", "Europe", "Africa". So be prepared impending wireless communications continents.

Moreover, Popov opened the effect radioeholokatsii, and used in his experiments radio communications between the courts not only antennas but also … live sunflowers, successfully cope with its mission — exploring the possibility of receiving radio signals by living organisms.

At the beginning of 1896 to Sir William Preece, scientist, inventor and important dignitaries face England — Chief Engineer of Government Telegraphs, who himself for many years unsuccessfully dealt with the problem of telegraphy without wires, Marconi was an Italian with sealed boxes, and announced that they are "new devices plan "that can make the transmission of signals wirelessly with the" help of Hertzian waves. " Responding to the understandable question of Sir William, who is he and what are his achievements in physics, Marconi proudly replied that "the university is not finished," but took a course with Professor of Riga and is very interested in his experiments with electric rays, and then took hold of the invention unique devices.

Further events unfolded rapidly. Marconi takes a provisional patent on the invention, the content of which is kept secret and a half years. Over this period, a public limited company on the implementation and operation of the new invention, which comprises the Marconi himself and his high-ranking patron Price. In the summer of 1897, Sir William Preece makes a report to the Royal Society, which takes the mystery out of the "discovery" Marconi, proclaiming it to the world the inventor of wireless telegraphy.

Old Oliver Lodge, a famous English physicist (as AI Berg writes in his book "Alexander Popov, and the invention of the radio") sarcastically commented famous report: "The Italian enthusiast, having learned from the professor of Riga on initiation and propagation of waves of Hertz and their detection of metal shavings, undoubtedly a gifted sense of humor and great energy, having free time, started the production of a suitable koherera (Coherer — (koherer), a sensitive indicator of electromagnetic waves) packed it in a sealed box and brought to England as a secret invention for further alarm wirelessly. influential people he was introduced to the chief engineer of the Government telegraph, apparently too busy to remember about the latest developments in the field of Hertzian waves, as a result, it was announced that the boxes contain a "new plan, which was brought to England." was followed by a lecture at the Royal Society, and experienced officials have made tests with a conventional art for them. "

Bitter sarcasm Lodge is clear: he himself, experimenting with electromagnetic waves passed "landmark" discovery, and learning about the experiences Popov, admitted that no matter how silly, but the thought of using waves for long-range never crossed his mind. Went by this discovery and the discoverer of the "electric ray" Heinrich Hertz, like many others after him. Yes, this discovery was paramount to a brilliant insight! This is — apart from scientific prediction, except for the deep knowledge and understanding of physical laws and phenomena!

With the discovery of radio life of humanity flowed differently: accelerated the pace of work, decision-making, evaluation of events, because it is the speed of communication determines the level of any civilization. That’s why a hundred years after the discovery of radio and the first demonstrations Popov radio does not stop the dispute about which country has priority.

In 1908, a commission of respected scientists in the world, became the chairman of the OD Chwolson entered it and Riga, Branly, Lodge, Ducretet. The opinion was unanimous: yes, the priority of the invention of radio for Russian scientists!

The commission’s report was published in the Russian and foreign journals.

It seems the incident was over …

But with the onset of the Cold War, in 1947, the Italian Minister of Merlin has publicly declared that the invention of the radio belongs to the reigns of his country, the home of "the great Marconi."

World began a campaign to discredit the AS Popov, 40 years after his death …

Popov was an ardent patriot. Close associate of Alexander Popov PN Rybkin recalls that when working on the application of Popov’s radio on ships caught the attention of foreign businessmen, priests, there were several "tempting" offers to move for work abroad. However, Popov decisively rejected them. He stated: "I — Russian people and all of their knowledge, all their work, all the achievements I have the right to give only my country. I am proud to have been born Russian. And if not contemporaries, it may be that our descendants will understand how great my devotion to our country and how happy I am that it is not abroad, in Russia opened a new means of communication. "

Immortal invention A. Popov — one of the best achievements of modern civilization. Scientists believe that your radio he created for the glory of Russia.

Despite the development of cellular radio today remains one of the major means of transmitting information over a distance. It is more common, safe and high-quality means of conveying information, as almost does not fail. The invention AS Popov continues to serve the people.
