The Life of Characters in Philo farnsworth's Works

The word TV first appeared in 1900. The birth of television is one of the greatest events in the 20th century. History will remember the name of its inventor-an American boy of 14 years old. His name is Philo T.Farnsworth, and farnsworth was born in a farmhouse in Utah, USA in August 1906. Farnsworth showed signs of early wisdom when he was young. He has photographic memory and natural understanding of any mechanical device he has ever seen. Philo farnsworth studies in a primary school near his farm. He did well in school. He asked the teacher to give him special help in science. The teacher began to help Philo learn a lot of scientific knowledge, which most primary school students could not understand.

Farnsworth's parents are constantly moving to find an ideal place to live. When they settled in Idaho, 1 1 year-old Ferro was ecstatic when he learned that his new home had power transmission lines. He found bundles of old magazines of science and technology in the attic of his home, began to teach himself and decided to become an inventor. He soon began to do experiments with electricity. He built an engine by himself when 12 years old, and then built the first electric washing machine for his family.

As early as the 1920s, when Baird was addicted to mechanical manufacturing methods, at 192 1, there was a 14-year-old boy who was planting potato fields in his hometown. He was absorbed in a difficult problem: how to design a novel radio so that it could transmit moving pictures and sounds together? Farnsworth began to seriously consider developing television. He almost instinctively realized that it was not feasible to transmit images by mechanical devices. The young man also has an intuition that the research in the field of physics, which makes him feel novel, may hold the answer to this question. In any case, electrons can move at a speed unmatched by mechanical equipment, which makes the image clearer and means there is no need for moving parts. He reasoned that if a picture can be converted into an electron flow, it can spread in space like a radio wave, and finally it can be recombined into an image by a receiver. This is a fairly simple idea in essence, but no one seems to have thought of such a simple idea. Philo farnsworth had to solve several problems before developing a TV system. One problem is that he is only 14 years old. He knows that no one will listen to a child. In fact, experts say that at that time, only a dozen scientists in the world could understand his ideas. Another problem is that he has no money to realize his idea. One night, Philo read an article in a magazine about spreading images and sounds in the air. Anyone can receive this electronic information by using a device, and then they can watch these images. The article says that some of the greatest scientists in the world are working hard for this idea. These scientists are trying to make a device that can transmit images by using special machinery. This article caused Philo to think. 14-year-old Philo confirmed that these famous scientists were wrong. He thinks that such a machine is impossible to operate, and it will never run fast enough to clearly capture and reproduce electronic signals transmitted through the air. Philo believes that such a device must be electronic, not mechanical. Philo knows that the transmission speed of this electronic device must be very fast. What he has to do is how to develop such electronic equipment. Soon, Philo had the idea of developing a receiver: capturing light in a container and transmitting it with wires. Philo called it "the light in the bottle". A few days later, Philo and his teacher talked about a device that can capture images. He drew up a plan and gave it to his teacher. Philo's plan seems simple, but it still clearly conveys a message that a TV set needs to be developed. In fact, all TV sets today still use Philo's early ideas. Philo's teacher is Justin Dullman. Years later, Philo said that Mr. Durman guided him to imagine and opened the door to science for him. His idea of developing a TV system had to be postponed. Two years after graduating from high school, Philo entered Brigham Young University in Utah, but he didn't finish college. After his father died, he had to drop out of school. Philo didn't give up the idea of developing TV sets. A few years later, when he moved to San Francisco, California, he began to work hard to realize his idea. He was 2 1 year-old. History will remember the name of its inventor, Philo T. farnsworth.

Before farnsworth, British scientist John Logie Baird (1888 ~ 1946) has been committed to transmitting TV images through mechanical scanning. 1925 10 year 10.2, he finally made the first mechanical TV set that can transmit images, which is the prototype of TV. Although the puppet's face is fuzzy and noisy, seeing vivid images in an inconspicuous black box still attracts great interest. This new TV is called "Magic Box". 1927 On September 7th, Philo started a device, which was the first working TV receiver. In another room, it is the world's first TV camera. At the beginning of this year, Philo invented this special image tube. The picture presented by the TV receiver is not very clear, but the machine works and TV is invented. In the next few months, Philo found that several people were willing to invest in his invention. Baird is a representative figure who advocates the development of TV with mechanical scanning. 1928 developed the first color TV set. 1930, his system began to pilot audio TV programs, which made people immersive and made the old fable that "a scholar can know what's going on in the world without going out" come true. Therefore, Baird is called "the father of television". He died in 1946.

When the US Patent Office finally decided to make farnsworth the holder of all major TV patents, it was the end of 1930s, which was too late for farnsworth, and his funds were almost exhausted. With the approach of World War II, the federal government soon announced that it would suspend the development of the television industry. In this way, it will have to be postponed to 1946, so that TV production can legally start. By that time, farnsworth's patent has exceeded the protection period. 1930 In August, the American government granted Philo a patent certificate to protect his invention from being copied by others. However, before long, several inventors claimed that they had invented the television device. Among these inventors, one is Ferati Mill Sforokin, who works for the powerful American Broadcasting Corporation (RCA). RCA began to compete with Philo Farnsworth for the right of TV invention by legal means. It is said that Mr. Sforokin invented television in the 1920s. The powerful ABC claims that it, not Philo farnsworth Jr., has the right to produce, develop and sell TV sets.

The lawsuit between ABC and Farnsworth TV Company lasted for several years. ABC has proved that Mr. Sforokin made a TV set, but there is no valid evidence that this TV set ever worked. At the same time, ABC also claimed that after Mr. Sforokin invented the TV picture tube, Mr. farnsworth also invented the TV picture tube. When farnsworth said that he had this idea a long time ago, ABC said that it was almost impossible for a 14-year-old child to have the idea of developing TV sets. The representative of the company also said that Mr farnsworth might not even be a scientist. He never graduated from college. ABC said Philo farnsworth had to provide evidence that he invented the television picture tube. Philo can't provide such evidence, but his teacher can. In court, Justin Dullman came up with a plan made by Philo when he was a student a few years ago. At this time, ABC's legal experts knew that their lawsuit was lost, and Philo farnsworth won the lawsuit, so he had the right to invent television. However, he has no funds to develop his TV industry. It was not until the 1950s that television had an important influence on American life. The names of Vratimir Sforokin and David Chanove, presidents of ABC, are associated with this new industry. However, the manufacturers who were interested in making TV sets at that time seemed to be only interested in mechanical TVs that were destined to be eliminated. Few people appreciate farnsworth's invention except ABC. This company hired Russian immigrant Zuojin on 1930. At that time, Zorkin had made a prototype, the principle was similar to that invented by Farnsworth in 1927, but the imaging effect was not good, with only 40 ~ 50 lines per frame. Zokin went to San Francisco to visit farnsworth, who claimed to be a researcher interested in television. Farnsworth didn't know that Zorin was an "industrial spy". Lin Jinhua observed in the laboratory in farnsworth for three days, got the most confidential part of the invention, and then returned to the American Radio Company. Three years later, he made TV and started advertising. Farnsworth was anxious at this moment, and quickly sought cooperation from big companies in the industry. But at that time, most electronics factories produced radios and had to use the patents of American Radio Company. They don't want to get into trouble. Farnsworth and investors have no choice but to sue American Radio Company in the United States Patent Office. This invention turned into a protracted legal battle. Farnsworth's TV patent was obtained at 1927. Although the laboratory of American Radio Company didn't make TV until 1933, the company argued that a patent of image technology obtained by Zorkin in 1923 was the embryonic form of TV, while farnsworth produced earlier evidence. His teacher, tolman, testified that farnsworth had conceived the principle of television as early as middle school, and he also drew a sketch of farnsworth's idea in court. 1934, the United States Patent Office ruled that the TV patent belongs to farnsworth. ABC refused to accept the appeal, and the appeal proceedings lasted 16 months. The company lost again, but it still refused to give up. Various minor lawsuits dragged on for several years. The entanglement of ABC just responded to a famous saying of the company at that time: "We only accept royalties and never pay royalties." When farnsworth finally legally owned all the major patents on television, it was in the late 1930s. It's too late for farnsworth. His funds are almost used up. With the approach of World War II, the American government soon announced that it would suspend the development of the television industry. As a result, the legal production of TV had to be postponed until after 1946, when the patent in farnsworth had exceeded the protection period. As soon as the patent period passed, American Radio Company began to mass-produce TV sets, and in the overwhelming public relations activities, Zorkin and the company boss were promoted as the father of TV. Farnsworth could no longer resist. He sold his last fortune to the International Telephone and Telegraph Company and returned to his hometown with a gloomy mood. He was depressed, lived on alcohol anesthesia, was in poor health and stayed in bed for several months.

Since then, the name farnsworth has completely disappeared from people's sight. The only time he appeared on a national television program in the United States was at 1957. At that time, as a mysterious guest, he participated in a game program called "I know a secret" on CBS. In the program, the guests present can ask all kinds of questions to the guests, and finally guess the names of the guests to win. Unfortunately, the guests didn't guess who he was, and farnsworth won the prize of $80 as the winner. Among the questions, one is: "Have you invented something that will be painful to use?" Farnsworth replied, "Yes, sometimes it is very painful." In his later years, farnsworth vehemently criticized TV as an invention that wasted people's time, and even once banned children from watching TV. But just like pain, occasionally he can find happiness from TV. 1969 In July, farnsworth and his wife elma were watching TV at their home in Maine. The screen is showing the picture of the first human step on the surface of the moon. He said quietly to his wife, "You know, today is all worthwhile."

Farnsworth died of pneumonia in June. 197 1. The New York Times called him one of the greatest and most charming inventors in the world in his obituary. Since then, rigorous experts in the history of science and technology have determined that farnsworth invented television on September 7, 1927. The US Postal Service issued a commemorative stamp 1983 for him in recognition of his contribution to the development of human society. Time magazine listed him as one of the greatest scientists and thinkers in the 20th century 100. Philo farnsworth died in March 197 1. Today, his statue is located in the United States Capitol. He is one of the most important inventors in the 20th century.
