At one time, the invention of radio greatly advanced the development of all mankind. The ability to keep in touch with people hundreds of kilometers in the most favorable way affected all areas of civilization, from the army to industry. Not so long ago, in the USSR there were hundreds of thousands of ham enthusiasts, who, however, have not yet been extinct.
In Russia, there is a memorable Radio Day, which is celebrated on May 7. According to the polls, almost three quarters of all radio amateurs in Russia listen to radio only in the car. The October Revolution, which shocked Russia in 1917, was the first political event, the information of which was transmitted via radio. The first Internet radio station (Internet Talk Radio) began its work back in 1993. The Internet, contrary to forecasts, did not become the “killer” of the radio. On the contrary, the popularity of some radio stations has increased, because people have the opportunity to listen to them via the Internet, without a special radio. There is such an interesting radio station in the world as Bird Song Radio. All that is broadcast on it is recordings of bird songs recorded on tape a long time ago by one famous British ornithologist.
Until 2013, a law was in force in the United States prohibiting state radio stations from broadcasting in the United States. This incident arose because state radio was equated with propaganda, and propaganda in the United States is prohibited. Any, even your own. Radio reports of the famous leading Levitan for many generations have become the voice of the Great Patriotic War. Since they were not initially recorded, later, 5 years after the end of the war, they were specially recorded again because of their historical value. The word “hacker”, and this very concept too, appeared thanks to the radio. The first hackers were people who picked up and cracked passwords on secret radio stations. On April 18, 1930, music played on the BBC radio, which already existed then, all day, which puzzled the listeners. Later, the administration of the radio station explained that there was simply no interesting news on that day.
The inventor of the radio transmitter is the famous Serbian scientist Nikola Tesla. During the Second World War, several hundred Navajo North American Indians served in the U.S. Navy, transmitting messages in their own language. The Japanese intercepted them, but failed to decipher them. To this day, the most famous radio show in the world is the production of G. Wells’ War of the Worlds, played in the USA in 1938. It reported an attack by the Martians. Many people believed in the attack, panic began, and when the truth opened, the police barely managed to save the organizers of the play from the violence of an angry crowd. The Eiffel Tower, the symbol of Paris, was planned to be dismantled twenty years after its installation, as it was built specifically for the then held in the French capital World Exhibition. However, the radio actually saved her – as it turned out, the tower is great for placing antennas on it.
Even before the invention of the radio, the American dentist Mahlon Lumis conducted similar experiments, lifting kites with wires into the sky. After a series of experiments, he managed to transmit a signal at a distance of almost twenty kilometers. The world’s first radiogram was sent in 1896 by Alexander Popov, the man who invented the radio itself. It consisted of only two words – “Heinrich Hertz”. In 2009, it was first hypothesized that some bacteria could be sources of radio waves. Later, research and experiments confirmed that it is.
