Interesting facts about radio communications and television. Interesting facts about radio
116 years ago on this most significant day, May 7, the great inventor A.S. Popov created the first radio receiver. Needless to say, how strongly and irrevocably the invention of radio changed the history of human civilization. The forerunner of modern radios, mobile phones, televisions, radio telescopes and a bunch of other useful things, without which today’s man is without hands. To pay tribute to the history of the invention of radio, I decided to compile a selection of several interesting radio facts.
Happy holiday, friends!
1. The first experiments that contributed to the invention of radio were made by the American dentist Mahlon Loomis. Wireless connection was carried out using kites that lifted two wires into the air. Already in 1868, he was able to transmit a signal over a distance of more than 20 kilometers. So all dentists can be proud of this fact.
2. Our beloved Nikola Tesla also contributed his efforts to the development of radio communications. By the way, he patented a radio transmitter.
3. In Russia, many consider Alexander Popov to be the inventor of radio, but long before him, many scientists conducted experiments wireless transmission signal and not without success. Popov can be considered the first person to send a radiogram. Its text consisted of two words “Heinrich Hertz”.
4. At the turn of the century, the ship "Masens" was wrecked. During the rescue operation, radio communication was successfully used for the first time.
5. The first radio broadcast on the Internet was started by Karl Malamud in 1993. The station's name was “Internet Talk Radio.”
6. French virologist Luc Montagnier (Nobel Prize winner for the fight against HIV and AIDS) first suggested back in 2009 that bacteria can communicate with each other using radio waves. This caused a lot of debate among scientists who began to conduct detailed research on this topic.
Recently, a group of biophysicists from Northeastern University in Boston discovered how this so-called “radio of bacteria” functions. In their work, scientists relied on the fact that bacterial DNA in most cases is a closed loop. And an electron can “run” along it from atom to atom. As a quantum particle, when an electron moves, it will take different meanings energy, that is, to move between energy levels, while emitting energy. The frequency of such “jumps” will correspond to the frequency of the radiation.
According to calculations by Allen Wedom, the leader of the research team, the frequencies of electron emission when moving along the DNA ring correspond to 0.5, 1 and 1.5 kHz. Note that signals of precisely these frequencies were previously recorded in E. coli.
The problem, however, remains that while the model suggests that some bacteria can produce radio waves, there is no evidence that such radio waves are actually used as a means of communication. And this new topic for research.
A new study from Boston scientists is likely to inspire scientists to look deeper at the topic. The most important thing that has been established is that bacteria have enough means to generate radio signals.

Any modern man has the happiness of listening to the radio anywhere and anytime. That's why we love him. Do we know everything about him?
For you, we have collected several interesting facts about the already familiar technical miracle of Professor Alexander Stepanovich Popov.
1. What was first broadcast on the radio?
The first radiogram was sent in March 1896 by one of the most famous people in Russia - Russian physicist Alexander Popov. It contained only 2 words: “Heinrich Hertz.” 
2. Do bacteria use radio waves?
In 2009, the hypothesis that bacteria are capable of generating radio waves was put forward by French virologist Luc Montagnier. The results of his research confirm the fact that this is possible.3. Hackers and radio
The word "hacker" originated from radio. This was the name given to people who were known for cracking passwords on secret radio stations. 
4. Radio about the revolution
The first political event in the world, information about which was transmitted by radio, was the October Revolution of 1917. 
5.Radio extended the life of the Eiffel Tower
The Eiffel Tower was directly connected to the radio. It was built for the 1889 World Exhibition and was planned to be dismantled 20 years later. But with the advent of radio, antennas began to be installed on the tallest tower in Paris, this saved the famous building, which is now business card France. 
6.Where do people listen to the radio?
73% of people in the USA and Russia prefer to listen to the radio in the car.46% of people listen to the radio in the kitchen.
23% of Americans also have a radio in their bathroom.
7. Even the gods listen to the radio
In 1966, John Lennon said that The Beatles were more popular than Jesus Christ. A small Texas radio station, KLUE, outraged by this statement, held a public record burning event. famous group. The next day, the radio station building was struck by lightning, all equipment was destroyed, and the announcer lost consciousness. 
8. Rare languages are the basis of a reliable radio cipher
At the beginning of the 20th century, Americans used representatives of various Indian tribes as radio operators. It was extremely difficult for people unfamiliar with these rare languages to decipher the radiogram. During World War II, the experience came in handy. The Americans used the Basque language to encrypt secret radio messages, since it was not widely used in Europe. Neither the Germans nor the Japanese who intercepted the messages could decipher these texts. 
The editors of the site believe that radio is the fastest and most accessible media, it does not require interruption from everyday activities, develops imagination and can be everywhere!

1. Radio Day is celebrated annually in Russia on May 7, since on this day in 1895 the Russian physicist Alexander Popov carried out a communication session using a radio receiver he designed.
2. Since at the end of the 19th century many physicists were engaged in the study of radio communications, in addition to Alexander Popov, Italian is considered the father of radio engineer Guglielmo Marconi, American Serbian inventor Nikola Tesla, English physicist Oliver Joseph Lodge, French physicist and engineer Edouard Branly, Bengali scientist Jagadish Chandra Bose.
3. The first radio broadcasts in our country began to be transmitted from the Nizhny Novgorod Radio Laboratory in 1919. Before this, only Morse code was heard on the air, not the human voice.
4. In the 1920s, radio broadcasts began to be broadcast from experimental stations in different cities of the country, and in 1924 broadcasting became regular. Thus, radio became a mass media.
5. In the USSR, radio was at the peak of its popularity - radio circles operated at clubs, schools and universities, and enthusiasts assembled receivers using homemade methods.
6. The most famous announcer in the Soviet Union was Yuri Levitan, his voice was known to every resident of the country. Levitan has been an announcer at All-Union Radio since 1931. During the Great Patriotic War, he read Sovinformburo reports and orders Joseph Stalin, and it was he who was entrusted to inform the whole country about the capture of Berlin and the Victory.
7. It is interesting that it was the Soviet Union that first began broadcasting foreign countries to Western countries. Moscow Radio (later - "Voice of Russia") began to broadcast on foreign languages back in 1929. Western radio stations broadcasting in Russian, such as Radio Liberty and Voice of America, appeared much later, and during the Cold War they were jammed in every possible way.
8. In 1945, 50 years after the invention of radio, the “Radio Day” holiday appeared in the USSR, established “in order to popularize the achievements of domestic science and technology in the field of radio and encourage amateur radio among the general population.”
9. In the 1990s, the radio broadcasting system in Russia changed dramatically. Many commercial radio stations have appeared, especially music ones, but information and talk radio stations have remained, and moreover, they are popular, such as such a well-known station as “Echo of Moscow”.
10. Radio did not die even with the advent of the Internet, since it became possible to listen to it online without any receivers. In order to turn on the radio, now you just need to go to the website of your favorite radio station.
