1 The inventor of the electric light ( ) Choice: A. The Wright Brothers

The electric light invented by Edison.

Once, his mother had a disease, so Edison called a doctor. The doctor said: Your mother has appendicitis and needs surgery. It had to be bright. At that time, his home was far away from the hospital, and it was almost getting dark. Eddie thought vividly, put the cabinet in front of the bed, and put a large mirror on the cabinet. Then, the mirror reflected the light. After saving his mother, the doctor said movedly: "You saved your mother, and you gave her another life! So Edison invented the electric light!

Edison (1847- 1931)

The 19th century is known as the century of science, and it is also a century characterized by the technologicalization and socialization of science. In this century, science began to become an important part of social life. Innovation transformed into a huge power of technology and science. Some of the technological giants of this century continued to be active in the 20th century. Thomas Alva Edison was one of the 1000 people in the past named by the American "Life" magazine not long ago. Among the 100 most influential people of the year, Edison ranked first.

Edison came from a humble background and lived in poverty. His "education" was that he had only attended elementary school for three months in his life. Stunned by his weird questions, he actually told his mother that he was a fool and would have no future. His mother angrily asked him to drop out of school and let her educate him personally. At this time, Edison's talent was fully revealed. Under the guidance of his mother, he read a lot of books and built a small laboratory at home. In order to raise the necessary expenses for the laboratory, he had to go out to work as a newsboy and publish newspapers, and finally used the money he saved to carry luggage on the train. A small laboratory was built in the carriage to continue conducting chemical experiments. Later, the chemicals caught fire and almost burned the carriage. The angry porter threw all Edison's experimental equipment out of the carriage and slapped him several times. It is said that Edison was deaf for the rest of his life.

Edison is the kind of legendary figure admired by the American nation - although he did not receive a good school education, he achieved great success through personal struggle and extraordinary talent. With perseverance, rare enthusiasm and energy, he stood up from thousands of failures, overcame countless difficulties, and became an American inventor and entrepreneur. In his early years, he formulated the duplex and four-work formula. He invented the automatic telegraph system and the phonograph from 1877 to 1879. He also experimented with and improved electric lights (incandescent lamps) and telephones, and did a lot of work to realize centralized power supply. DC three-wire system. The largest capacity generator at that time was made, and the first large-scale power plant was built using this machine. In the same period, the "Edison effect" was discovered in 1883. Electron emission phenomenon. There are also many famous inventions in film technology, mining, construction, chemical industry, etc. From 1869 to 1901 alone, 1,328 invention patents were obtained. During his life, he invented a new invention every 15 days on average, so he was known as the "King of Inventions".

Edison devoted himself to science and was indifferent to fame and fortune. When developing electric lights, a reporter said to him: "If you can really make electric lights to replace gas lights, you will definitely make a lot of money." Edison replied: "If a person works just to save money, it will be difficult for him to get anything. Nothing else - not even money!" He has always been called the father of modern film, but at a grand banquet held by people in the film industry for his 77th birthday, he said: "As for the development of film, I He only made some technical efforts, and the rest is the credit of others."

Edison was open-minded and good at dealing with adversity. Regarding the inconvenience of his deafness, he said: "Walking among the crowds on Broadway, I can be as calm as a person living deep in the forest. Deafness has always been a blessing to me, and it has saved me a lot of distractions and mental pain." One night in 1914, Edison's film laboratory suddenly suffered a fire, causing huge losses.

Edison comforted his extremely sad wife and said: "It doesn't matter, even though I am 67 years old, I am not old.

From tomorrow morning, everything will start again. I believe that no one will age. I couldn't get back to work." The next day, Edison not only began to build a new workshop, but also began to invent a new light-a portable searchlight to help firefighters move forward in the dark. The fire was like a small episode for Edison.

Edison benefited the public and was not afraid of hardships. In search of a filament, he tested thousands of materials; in trying to create a new battery, he failed eight thousand times. Therefore, Edison often said: "Genius is one percent inspiration and ninety-nine percent diligence." At the age of 80, he still maintained the spirit of an inventor and carried out inventions and creations tenaciously. In 1927, he established the Edison Plant Research Company and devoted himself to a new research field, looking for new chemical materials. The 81-year-old Edison successfully extracted rubber from wild grasses and was highly praised by people.

At 3:24 in the morning on October 18, 1931, Edison closed his eyes and passed away with a relieved smile at the age of 84. When he was dying, he said calmly: "I have tried my best for the happiness of mankind; there is nothing to regret."

On the day of the funeral, the entire United States turned off the lights for one minute to express condolences. This is the most solemn way for people to express their infinite nostalgia for Edison, and it is also a silent hymn dedicated to this great inventor.
