After Marconi's death, radio stations around the world observed a minute of silence for him.
To show his respect.
Guillermo Marconi (1874- 1937) is an Italian electrical engineer and inventor.
1874 was born in bologna, Italy.
His family is very rich and he studies under the guidance of a tutor.
During his study in Bologna University, he used electromagnetic waves to conduct a radio communication experiment with a distance of about 2 kilometers, which was successful.
1909 He and Braun won the Nobel Prize in Physics.
1937 is dead.

In 1896, the test results can be used for communication with the distance of 14.4 km, and it has been patented in Britain.
1897, Marconi wireless telegraph company was established in London.
1899, at the request of France, radio communication was established between the two sides of the Anglo-French Strait.
19011February, radio communication across the Atlantic was realized between Britain and Newfoundland (3540 kilometers), which made the radio reach the practical stage.
1905- 1906, invented wireless telegraph technology to operate intermittent wave system.
19 1 1 year, Italy used the radio station he invented for the first time in the war with Turkey.
19 15, Italy participated in the first world war and was responsible for all the radio communications of the Italian army.
Later, he engaged in the research of short wave and ultrashort wave.
1909 won the nobel prize in physics with Braun.
From 19 18, he served as a lifelong senator of Italy, and later (1929) was awarded the title of Marquis.
1937, died in Rome.
Edit this invention process
1894 Marconi, who was 20 years old, learned about heinrich hertz's experiment a few years ago. The experiment clearly showed that invisible electromagnetic waves existed and these electromagnetic waves propagated in the air at the speed of light.
Marconi soon thought that this kind of radio wave could be used to transmit signals to far places without wires, which made it possible for many communications that telegrams could not complete.
For example, information can be transmitted to ships sailing at sea in this way.
After a year of hard work, Marconi successfully invented a working device in 1895. 1896, he made a demonstration test of the device in Britain and obtained the patent right of this invention for the first time.
Marconi immediately set up a company and launched the first radio in 1898.
The next year, his radio signal crossed the English Channel.
Although Marconi's most important patent was obtained in 1900, he constantly improved his invention and obtained many patents from it.
190 1 year, his radio message successfully crossed the Atlantic Ocean and spread from England to Newfoundland, Canada.
The importance of this invention was dramatically proved in an accident.
1909 * * * steamboat Guo sank to the bottom of the sea due to collision. At this time, the radio information played a role, and all the crew members were rescued except six people.
In the same year, Marconi won the Nobel Prize for his invention.
The next year, his radio message successfully spread from Ireland to Argentina, with a total length of 6,000 miles.
All this information is transmitted through the dotted line system of Morse code.
At that time, it was known that sound could also be transmitted by radio, but it was only realized in about 19 15 years. Commercial radio broadcasting just started in the early 1930s, but its popularity and importance increased rapidly.
If the patent of an invention is priceless, then the invention will definitely cause legal disputes.
19 14, the court withdrew the lawsuit and announced that Marconi had obvious priority in the patent right.
Marconi made important research on short wave and microwave communication in his later years.
He died in Rome on 1937.
Guillermo Marconi-The Invention of Radio
Radio technology is a communication method that uses radio waves to transmit information.
Voice, text, data and images can be transmitted.
Compared with wired communication, it does not need to erect transmission lines, is not limited by communication distance, has good maneuverability and is established quickly; However, the transmission quality is unstable, the signal is easily interfered or intercepted, and the confidentiality is poor.
After the invention of telegraph and telephone, the speed of information dissemination was many times faster than before.
The emergence of telegraph and telephone shortened the sense of distance between people from all continents.
But at the beginning, telegrams and telephones all transmitted signals in wires by current, which greatly restricted communication.
For example, communication must first have lines, and the erection of lines is limited by objective conditions.
Mountains and rivers bring great difficulties to the construction and maintenance of the line.
Moreover, ships on the sea that need communication very much, as well as airplanes invented later, cannot communicate with people on the ground through wires because they are all mobile means of transportation.
/kloc-the radio communication technology invented in the 0/9th century makes communication get rid of the way of relying on wires, which is a leap in communication technology and an important achievement in the history of human science and technology.
1894, in the year of Hertz's death, Marconi had just turned 20. He read about Hertz's experiment and Lodge's report in an electrical magazine.
He liked playing with coils and electric bells since he was a child, so he plunged into the study of electromagnetic waves.
He believes that since Hertz can detect electromagnetic waves several meters away, as long as there is a sensitive enough detector, it will certainly be able to detect further electromagnetic waves.
After many failures, he finally took a gratifying first step.
He installed a device for emitting radio waves upstairs in his home, and placed a detector downstairs, which was connected with an electric bell.
As soon as he turned on the power upstairs, the bell rang downstairs.
In the evening, when my father saw this novel device, he threw all the anger and dissatisfaction he had been holding in his stomach to the outside world, and never called him an "unrealistic visionary" again.
And began to give financial aid to his son so that he could concentrate on his experiments.
After his first success, Marconi's confidence increased.
He collected a large number of materials and articles, regardless of whether the authors of these articles are famous or unknown. As long as it is useful and enlightening to him, he reads patiently and analyzes carefully.
He clearly analyzed the shortcomings of each family and combined their strengths to improve the machine.
The following summer, Marconi completed another very successful experiment.
In autumn, the experiment made great progress.
He unfolded a kerosene bucket and turned it into a big iron plate as an antenna for launching.
The antenna of the receiver is hung high on a big tree to increase the sensitivity of reception.
He also improved Rocky's metal powder detector, adding a small amount of silver powder to the glass tube, mixing it with nickel powder, and then removing the air from the glass tube.
In this way, the transmitter increases the power and the receiver also increases the sensitivity.
He put the transmitter on one side of the hill and the receiver at home on the other side of the hill.
When sending a signal to his assistant, the receiver he was waiting for received the signal, which made the bell sound crisp.
For him, this noise is more pleasant than a touching symphony.
The distance of this experiment is 2.7 kilometers.
1937, Marconi died, and nearly ten thousand people buried him in Rome, Italy. At the same time, all wireless telegrams and telephones in Britain and BBC radio stopped working for 2 minutes to pay tribute to this great man in the radio field.
Marconi and other scientists who contributed to the field of radio communication left this world, but the radio communication they invented was left to future generations and will benefit future generations of mankind.
Because Marconi is only famous as an inventor, his influence is obviously proportional to the significance of radio and its products.
Obviously, radio communication is extremely important in the modern world.
Can be used for news, entertainment, military, scientific research, police and other purposes.
Although telegraph (invented half a century before radio) can also play the same role in some uses, radio is irreplaceable in many uses. It can communicate with cars on the ground, ships at sea, planes in the air and even space shuttles. Obviously, the invention of radio is more important than the invention of telegraph, because the information sent by telegraph can be sent by radio, and radio information can reach some places that telegraph can't.
Marconi ranks higher than Alexander Greer Bell in "100 Most Influential People in History" only because radio communication is more important than the invention of telegraph.
Edison ranked a little higher than Marconi because he had many inventions, although none of them were as important as radio.
Since radio and television are only a small part of the practical application of michael faraday and james clerk maxwell's theory, it seems reasonable that Marconi falls behind these two figures.
It seems self-evident that only a few of the most important politicians can compare with Marconi in terms of their influence on the world.
Therefore, Marconi's ranking among the "most influential 100 people in history" is relatively high (note: it ranks 4 100 people).
