Question 2: Who is the father of radio? At the end of last century and the beginning of this century, the invention and use of radio broadcasting opened a brand-new page in the history of foreign propaganda. 1895, Italian Marconi and Russian popov invented the radio almost at the same time, but Marconi got the international patent first. Since then, transmitting and receiving equipment has appeared, and has been continuously improved in a short time, reaching the level of a large number of use. Countries all over the world are competing to build radio stations and produce radios. With the increasing transmission power, especially the use of short-wave frequency, radio waves travel farther and farther, even across national boundaries, so international broadcasting has gradually emerged.
Question 3: Who are the king of explosives, the father of airplanes, the father of radio and the inventor of television? 1: Nobel is called "the father of explosives".
2. The father of the plane-the Wright brothers [In Brazil, everyone thinks this statement is wrong. They claim that the real "father of flying" in the world is a man named Albert? Santos? Brazilian in Dumont]]
3. Marconi, the father of radio
Marconi was born in a wealthy family in Italy. He likes reading and doing experiments since he was a child. He equipped himself with a small laboratory, doing chemical experiments first and then electrical experiments. He saw that it was very laborious for wired telegrams to set up lines, and he thought: Can electromagnetic waves be used to transmit telegrams? From 65438 to 0895, 20-year-old Marconi successfully conducted radio wave transmission experiments in his garden. Mother was very happy and gave him 1000 dollars to encourage him to continue his experiment. The scale of the experiment is gradually expanding. In order to find the source of funds, Marconi, 22, came to Britain to continue his research with the support of Britain. 1897, he and his assistant conducted a cross-sea communication experiment on the British coast. They installed the transmitter in a small house by the sea. Outside the house stood a tall pole with an antenna made of a metal cylinder. At the beginning, the receiver was placed on an island 4.8 kilometers away from the coast, and the communication effect was good. Then he expanded the distance to 14.5 km, and it also succeeded. In the following years, Marconi improved the communication device and increased the communication distance. 190 1 February, Marconi realized more than 2,000 miles of overseas communication from Britain to Canada, which marked that radio has become a global undertaking. 1909, Marconi won the Nobel Prize in Physics.
4. The inventor of TV-Baird 1929 One day, when the British first saw TV images, they were all in high spirits and rushed to tell each other. Among them, TV inventor Baird (1888 ――1946) shed tears with excitement.
This is generally accepted.
But there are different views.
Question 4: Who is Tesla, the "father of radio"? Often, real technical experts are also people who don't show off. This law has not changed until now. For example, the so-called masters are all big fools. This guy also invented alternating current, which has nothing to do with Edison. Edison invented electric light and direct current, and Tesla invented alternating current. After his death, all the manuscripts were confiscated by the FBI.
Question 5: Who is the "father of radio" from which country? Marconi (USA)/KOOC-0/903/KOOC-0/8/KOOC-0/October/KOOC-0/8, Marconi erected four wooden columns with a height of 2/KOOC-0/0 feet on the sand dunes on the coast of Cape Cod as "launch towers". Later, he built two identical "transmission towers" on the coast of Cornwall and Gibton Island in eastern England, respectively, as relay stations for radio signals. In the whole process, McConnell didn't get any help. He finished all the work with two hands. You can imagine how much he suffered. When the news of the successful telegram reached Washington, President Roosevelt praised Marconi as a "wizard" many times. Become famous overnight. Marconi won the 1909 Nobel Prize in Physics. The tower he built in Cod Point has also been used until 19 18. 19 12, the launch tower also received the distress signal from the Titanic.
Question 6: Who invented radio? Radio is one of the greatest inventions in the history of science. With radio, people can communicate with each other quickly and conveniently no matter where they are on the earth.
Who invented radio? It is recognized in the west; Marconi Russia thinks it is; Popov, this issue has been debated for more than a century, and it is still inconclusive.
Popov 1859 was born in March in a pastor's family in Russian Urals. He has a special interest in electrical technology since he was a child. /kloc-when he was 0/2 years old, he made a battery and converted the clock at home into an electric bell alarm clock. /kloc-at the age of 0/8, popov was admitted to the Physics Department of Petersburg University and soon transferred to the Forestry College to study. The active academic atmosphere here laid a solid foundation for him. Because of his poor family, popov had to work and study, and graduated with excellent results.
1888, popov began to sprout after hearing the news that Hertz had discovered electromagnetic waves. The dream of making electromagnetic waves leap across the globe.
1894 35-year-old popov successfully invented the most advanced radio receiver in the world at that time, and popov's main contribution to radio communication was that he discovered it; The function of the antenna, the line used by his receiver is the first antenna in the world.
1On May 7th, 895, popov read a paper and gave a demonstration at the Russian Physics Society in Petersburg with his invented radio receiver. The result was very successful.
1on March 24th, 896, another formal Morse code radio transmission performance was held in popov. Popov put the receiver in the conference hall of the Physical Society, and then installed the transmitter in the Forest College, 250 meters away. When his assistant gave a signal, the receiver in popov immediately received the signal clearly, but popov's invention was not adopted in Russia.
1895, popov applied to Russia for 1000 rubles for investment in radio experiments, but the minister of the army told him; I will never allow money to be wasted on such a fantasy.
Let's talk about Marconi again He was born in Italy on 1874. 1894 When Hertz died, Marconi, who had just turned 20, read Hertz's experimental report in an electrical magazine. I like to play with coil bells since I was a child, and I have a strong interest in electromagnetic waves at once, he thinks; Since Hertz can detect electromagnetic waves several meters away, as long as there is a sensitive receiver, it will certainly be able to receive further electromagnetic waves. He installed a device for emitting radio waves upstairs at home, and placed a receiver downstairs to connect with the electric bell. When his father saw that he had not done his job well, he was very dissatisfied. He was called an unrealistic visionary, and his neighbors mocked him in every way. But he was not discouraged. Finally, one day, his father was reading a newspaper downstairs when he heard a burst of * * *. Then, his son ran down happily, hugged him and shouted. I made it! At this time, the father saw his son's outstanding talent and began to give Marconi financial support so that he could concentrate on his experiments. The following summer, Marconi completed another very successful experiment, and in autumn, the experiment made unprecedented progress. He put the transmitter on one side of a hill and the receiver on the other side of the hill, with a distance of 2.7 kilometers between them. When the assistant gave the signal, the bell of the receiver he was waiting for rang clearly.
But the next experiment needs a lot of money, and my father can't afford it. Marconi turned to * * * for help, but the conservative Italian authorities insisted. But the British showed great interest in it, and many consortia were willing to support him. So Marconi came to England at 1896.
190 1 year, Marconi built a towering tower in Britain to send signals to the other side of the Atlantic, which was successful. 1937 Marconi died, and nearly 10,000 people in Italy mourned his funeral. All radio, telegraph, telephone and radio stations in Britain stopped working for two minutes.
1905, a lawsuit about the right of radio invention was raging in the United States. Finally, the North American Circuit Court ruled; Marconi was the inventor of radio. The following year, popov died of cerebral hemorrhage at the age of 47.
1909165438+10 In October, Marconi, 35, won the Nobel Prize in Physics that year. Although Marconi's position in the west is unshakable, Russians always believe that; Popov was the first person to invent radio. The case has not been solved.
In fact, other countries have different views on the inventor of radio; The British regarded Maxwell as the father of radio and thought that he was the first person to point out the existence of electromagnetic waves. Germans believe that; Hertz was a pioneer of radio because he first discovered electromagnetic waves. Americans ... >>
Question 7: Who is the father of the plane? At present, there are three recognized opinions about who is the father of the plane, but they are also the most controversial:
First, experts in world aviation history claimed that the title of "father of airplanes" was awarded to the Wright brothers. Some scholars believe that this is actually a "historical mistake". The Wright brothers' test pilot flight in 1903 was actually not the first successful flight in human history!
Secondly, as early as August of 190 1, Whitehead successfully tested the "vulture" plane invented by himself in a wilderness in Bridgeport, Connecticut, USA, at least two years before the Wright brothers successfully tested the plane for the first time. Some experts in world aviation history believe that Whitehead, a German immigrant, is the real "father of airplanes" in human history. Although some mainstream American aviation historians, including the Smithsonian Institution, remain silent about this statement, Jane's Global Aircraft, one of the most authoritative aviation history publications in the United States, supports this statement, arguing that the "father of aircraft" who invented the world's first manned aircraft was not the Wright brothers, but the Wright brothers.
Third, just as people were puzzled, a familiar Parisian face appeared in front of the plane. He is alberto Santos Dumont, an aviation pioneer from Brazil, a South American country. Under the watchful eyes of the French "Aviation Club" expert group and 1000 Parisians, Santos Dumont flew into the sky 3 meters high with his own 14 BIS, relying on the engine of the plane itself. When the plane landed safely, the audience cheered Du. The flight scene was recorded on film. European media reported that this was the first successful power flight in human history.
In addition, although Whitehead may be the real "father of aircraft" and "the first person to fly in the world", the bird-wing wing he invented is not suitable for modern jet aircraft. Although similar wings are still used in some hang gliders and ultralight aircraft, the model aircraft designed by the Wright brothers can be called the "ancestor" of modern jet aircraft.
Who is the "father of the plane" has not been officially confirmed yet, but according to reliable evidence, it is very likely that the father of the plane is the three characters mentioned above, namely the Wright brothers, whitehead and Alberto Santos dumont.
