Who invented the radio? Recognized in the West is Marconi. Russia is considered to be Popov, the issue of debate for more than a century, so far there is no conclusion.
In March 1859, Popov was born in a family of priests in Ural, Russia, where he had a special hobby for electrical technology. 12 years old, made a piece of their own battery, but also with the bell to the home of the bell converted into an alarm clock. At the age of 18, Bobov was admitted to the Department of Physics at the University of Petersburg, and soon transferred to the College of Forestry to learn, where the active academic atmosphere to lay a solid foundation for his family poverty, Bobov had to work half-time to maintain learning, And graduated with honors.
In 1888, Popov heard Hertz discovered the news of electromagnetic waves, he began to sprout to make electromagnetic waves leap the dream of the world.
In 1894, 35-year-old Popov successfully invented the world's most advanced radio receiver, Popov's main contribution to radio communications is that he found the role of the antenna, his receiver used wire is the world On the first antenna.
May 7, 1895, Bobov with his invention of the radio receiver in the Petersburg, the Russian Institute of Physics read the papers, and the demonstration, the results of great success.
March 24, 1896, Popov and carried out a formal radio transmission Morse code performance, Popov placed the receiver in the physics conference hall, and then the transmitter installed in the Forest Academy, two The distance between 250 meters, when his assistant to send out the signal, Bobo Fu side of the receiver immediately received a clear signal, but Bobov's invention in Russia has not been adopted.
In 1895, Popov once applied to the Russian government for 1,000 rubles for radio experiments, but the army minister told him that Russia would never allow money to be wasted in such fantasies.
Speaking of Marconi, in 1874 he was born in the Italian family of a farmer. In 1894 Hertz died, just over 20-year-old Marconi in the electrical magazine read Hertz's experimental report. From an early age like to play with the coil bell, he suddenly had a strong interest in electromagnetic waves, he believes that since Hertz can measure electromagnetic waves in a few meters away, then as long as there is enough sensitive receiver, will be able to receive in more distant places To electromagnetic waves. He installed the radio at home upstairs, and the receiver was connected to the bell. Father to see him do not work is greatly dissatisfied, denounced him is unrealistic visionary, the neighbors are all his ridicule. But he was not discouraged, and finally one day, my father was downstairs to see the newspaper suddenly heard a ring of bells, then, his son happily ran down holding him shouting: I succeeded! Father at this time to see his son's outstanding talent, began to Marconi economic support, let him bent on experiment. The second year of the summer, Marconi has completed a very successful experiment, to the fall, the experiment has made unprecedented progress. He placed the transmitter on the side of a hill, the receiver placed on the other side of the hill, the middle distance of 2.7 km, when the assistant sent a signal when he was waiting for the receiver's bell issued a crisp ring.
But the next experiment requires a lot of money, the father has no ability to supply. So Marconi sought assistance from the government, but the conservative Italian authorities dismissed it. However, the British have shown a strong interest in this, many consortium willing to support him. So Marconi came to England in 1896
In 1901, Marconi in the United Kingdom to establish a towering tower to the other side of the Atlantic launch signal, was successful. In 1937 Marconi died, Italy has nearly ten thousand people for his funeral, all the British radio and radiotelephony and radio station suspension for two minutes to his mourning.
In 1905, a lawsuit against the right to radio was raised in the United States. Eventually, the North American Circuit Court ruled that Marconi was the inventor of the radio. The second year, Popov died of cerebral hemorrhage, at the age of 47 years old.
In November 1909, 35-year-old Marconi won the Nobel Prize in Physics for the year. Although Marconi's position in the West has been unshakable, but the Russians have always believed that Popov is the first invented radio people. This case has not yet been resolved.
In fact, the inventor of the radio, other countries have different views, the British to Mike Wei as the father of radio, that he first pointed out that the existence of electromagnetic waves. The Germans believe that Hertz is the pioneer of radio, because he first discovered the electromagnetic waves. The Americans argued that Deverest was a radio inventor because he invented the heart of the radiocommunication equipment - the transistor.
Who invented the radio? It may be argued that the invention of radio is the crystallization of the collective wisdom of many scientists, their achievements are indelible. |
