Radio is invented by anyone?

Imagine what your life would be like if you didn't have a radio, if you didn't watch TV one day? Receiving information on the radio is a habit, an important part of your life. But have you ever asked the question: who invented radio or not?

In ancient times, people spread the word by running or running, both time-consuming and labor-intensive. By the nineteenth century, along with the development of capitalist production, ancient ways of communicating could not meet the need for rapid communication, even though new methods such as by train were used. , ships. After powering up the science arena, people yearn to open a news revolution in electricity. In order to solve that difficult science and technology problem, many people have spent so much effort and enthusiasm on this difficult scientific path. They finally exchanged a series of great scientific achievements: Americans Breese Morse (1791 - 1872) successfully built the useful telegraph machine , and built the road in the late 1930s. The first wire telegraph between Washington and Baltimore and in 1844. In 1876, American Bell (1847 - 1922) invented a stethoscope. In the 1990s, there were people who invented the radio telegraph. But who discovered the radio first? So far that is still a problem that people still debate over and over again.

It is said that the radio was discovered by Italian Markeni (1841 - 1937) . Because in 1894, when Markeni was only 20 years old, he discovered the nature of the electromagnetic wave in Hertz's late statement, thereby creating the idea of ​​taking advantage of electromagnetic waves to conduct information by radio. Since then, he established a wireless limited liability company, started producing electromagnetic wave induction coils and detectors. But he was not satisfied with the radio telegraph that could only be used on a short range. In 1901, Markeni built a sky-high broadcasting station in England, signaling electrical waves from across the Atlantic.

But there are many Soviet scholars who believe that the first person to invent radio was not Markeni, but Russian scientist Popov . These scholars said: Popov invented the first radio telegraph in 1895. Soon after Popov invented the radio telegraph, 27 iceberg fishermen lost their way to the Polo sea, thanks to the telegraph. Radio that is saved. But Popov's radio telegraph has not been used in Russia.

In 1895, when he asked the Government to donate 1000 Rups to equip radio telegraph equipment, the Army Minister answered: 'I do not allow the use of money for such paranoid things '. This invention was later used by Markeni, who tried to gain a priority to invent this radio for himself. Even, it was claimed that Popov's invention, which the Tsar of the Conservatives did not bother to use, was taken by the mercenary who had been taken by Markeni, who had impersonated this great invention.

There are scholars who try to regulate this controversy, arguing that creation of radio communication tools is due to Markeni and Popov seemingly completed at the same time. They said: Inventing radio is the most important scientific and technical achievements of the nineteenth century. In 1888, German scientist Hertz discovered electromagnetic waves while experimenting with electric discharge, fully attesting to James Maxwell's speculation about electromagnetic waves. Taking advantage of this type of radio waves to carry out information, it seems to have been completed by the engineer, Markeni and Russian scientist Popov.

In short, the above opinions are different, in the end, the first radio inventor was Markeni or Popov, so far it has not been possible to give a final conclusion.
