100 years ago today, on October 2, 1925 (August 15, 1925 lunar calendar), British inventor Baird invented television. John Logie Baird was a British electrical engineer and pioneer in the development of television. He was born in the family of a priest in Helensburg, Scotland, and showed an inventor's genius from an early age. Baird studied at the University of Glasgow and the Royal TechAcademy. During the First World War, Baird became the head of a large power company after he declared himself unfit to serve in the army. In 1924, Baird made a series of experiments to transmit images for the first time using a collection of old radio equipment, neon tubes, scanning plates, electric heating rods, and magnetic wave lamps and phototubes that could generate electricity intermittently. However, these test materials were so worn out that each test required some parts to be damaged and replaced. John Baird and his television transmitter went through hundreds of tests, and Baird summed up a lot of experience. On the morning of October 2, 1925, when Baird started the machine in the room again, as the motor speed increased, he finally received the face of Bill, a performance doll, clearly from the image receiver in another room. Baird was so excited that his dream of inventing "television" for many years came true. Although it was not perfect, it was a successful experiment. Then Baird persuaded Gordon Selfridge, a wealthy company owner, to sponsor him and focus more on television. On January 27, 1926, Baird's machine was significantly improved. He immediately wrote a letter to the British Society for the Popularization of Science, asking it to observe it in the field. When Baird transmitted Bill's face and the faces of others from one room to another, the invited experts agreed that it was an incredibly great invention. The sponsors soon realized that the market potential of this invention was vast, so they invested in it and established several companies. In the spring of 1928, Baird developed a color stereoscopic television, which successfully transmitted images to the other side of the Atlantic Ocean, becoming a prelude to satellite television. A month later, he sent the airwaves to the Berencary cruise ship, much to the excitement and surprise of all the passengers. Baird was very proud of this period. Compared with several other inventors of his generation who were also inventing television, his technology stood out above other inventors. However, the good times did not last long. In 1936, Baird met a strong competitor - the Electric and Musical Instrument Industry Company invented the all-electronic television. After a period of comparison, experts concluded in February 1937 that Baird's mechanical scanning system was not as good as the all-electronic system of the Electric and Musical Instrument Industry. Baird had to find another market. However, just as he wanted to further study the new color system, he suddenly contracted pneumonia and died tragically in 1946. Today, Baird's invention of television has developed to an amazing extent. Clear and vivid television has become a necessity in real life. In 1962, the communications satellite was put into space orbit, and communication between the continents was no longer difficult. People can know what is happening in every corner of the world by sitting at home, and the distance between people in space and time has been shortened. All this is thanks to Baird's invention.
