4. Edison was born on February 12, 1847 in the small town of Milan, Ohio in the Midwest of the United States. His father is a descendant of the Dutch, and his mother, a former primary school teacher, is a descendant of the Scots. When Edison was seven years old, his father lost money in the tile business and moved his family to Fort gratiott, a northern suburb of Huron, Michigan. Soon after he moved here, Edison suffered from scarlet fever, which is believed to be the cause of his deafness. Edison went to school at the age of 8, but after only three months of reading, he was expelled from school because of his teacher's "incompetence". From then on, his mother was his "tutor" and decided to teach his son to read and read, and taught him to be honest, love the motherland and love human beings. Because of his mother's good ecation method, he had a strong interest in reading“ He not only read extensively, but also read everything at a glance. At the age of 8, he read the works of Shakespeare and Dickens, the most important playwrights in the British Renaissance, and many important historical books. At the age of 9, he could quickly read difficult books, such as nature and experimental philosophy by Parker
Edison's earliest interest in natural science was in chemistry. When I was 10 years old, I loved chemistry. He collected about 200 bottles, and saved every penny to buy chemicals and put them in bottles. At the age of 11, he experimented with his first telegram. In order to make money to buy chemicals and equipment, he began to work. At the age of 12, he got a job selling newspapers on trains, traveling between Port Huron and Detroit, Michigan. He sells newspapers while doing fruit and vegetable business. Whenever he has time, he goes to the library to read. In 1861, the civil war broke out in the United States. Edison, who had just turned 14 years old, bought an old printing press and used the convenience of the train to run a tabloid (weekly), the herald, to convey the war situation and the news along the way. The first weekly was printed on the train. He is a journalist, editor, typesetter, proofreader, printer and distributor. The tabloids were popular, and he gained talent, knowledge and experience from his intense work. He also earned a lot of money to continue his chemical experiments. With the money he earned, he set up a chemical laboratory on the luggage cart. But unfortunately, when he was doing an experiment on the train, the train suddenly bumped, causing a piece of phosphorus to fall on the board and cause combustion. The conctor came to put out the fire and slapped him in the face. He was driven off the train when Edison was only 15 years old Another way is: Unfortunately, once a chemical caught fire, he and his equipment were thrown out of the car. Another time, while Edison was trying to get on a freight train, a conctor grabbed his ears to help him get on. This action led Edison to be deaf for life.)< In 1868, he invented an automatic electric recorder, which was his first invention. Later he invented two new types of telegraph. In 1877, he invented the carbon telephone transmitter, which made the original telephone sound clearer; In addition, he invented the phonograph. People call him "the magician"< In September 1878, Edison began to study electric light when he was 31 years old. At that time, the gas lamp had replaced the kerosene lamp, but the flame flickered and proced harmful gas when it was extinguished; Arc lamp has also been invented and used in public places, but it is not suitable for indoor use because of the hissing sound and too bright when burning. At that time, many European and American scientists had been exploring the manufacture of a new stable luminescent body< After studying the arc lamp, Edison announced that he could invent a satisfactory light, but it needed money. At that time, he was already a person with 170 invention patents. His invention brought great profits to capitalists, so a consortium was willing to provide him with financial support. After thousands of failures, in April 1879, he improved the previous rod-shaped and tubular lamp and made a glass ball; On October 21, 1879, he fixed a carbon treated cotton thread in a glass bubble, pumped out air, sealed the mouth, and applied electric current. It glowed, and a new kind of lighting appeared
from 1880 to 1882, Edison designed electric light socket, button, fuse, current cut-off device, ammeter, hanging lamp, main line and branch line system, made the largest generator in the world at that time, built the first power plant in New York, and opened the first civil lighting system. Later, together with George Eastman, he invented the motion picture camera. Edison's three great inventions: phonograph, electric light and power system, film camera, enriched and improved the civilized life of mankind< Edison died on October 18, 1931, at the age of 84. However, so far no one has been able to break his record of 1099 invention patents. People call him the king of invention< In August 1862, Edison rescued a boy who was about to die on the track of a train. The father was grateful for this, but he was willing to teach him telegraph technology because he had no money to pay for it. From then on, Edison had a relationship with this mysterious new world of electricity and embarked on the journey of science< In 1863, Edison served as a telegrapher at Stratford junction station of the main line railway. From 1864 to 1867, he worked as a telegraph operator in the central and western regions and lived a life similar to wandering. The footprints include Stratford, Adrian, Fort Wayne, Indianapolis, Connecticut, Nashville, Tennessee, Memphis, Louisville and Huron
in early June 1869, he came to New York to look for a job. While he was waiting for a call in an agent's office, a telegraph broke down. Edison was the only one there who could fix the telegraph, so he got a better job than he expected. In October, he and Popper set up a "Popper Edison Company" to specialize in scientific instruments for electrical engineering. Here, he invented the "Edison universal press". He dedicated the press to the manager of a big Wall Street company. He wanted to ask for $5000, but he didn't have the courage to say it. So he asked the manager to give him a price, and the manager gave him $40000
Edison used the money to build a factory on ward street in Newark, New Jersey, which specializes in manufacturing all kinds of electrical machinery. He works all night. He trained a lot of capable assistants. At the same time, he ran into the diligent Mary Stilwell, his first bride in the future. In Newark, he made such inventions as wax paper and mimeograph. From 1872 to 1875, Edison invented the double Telegraph and quadruple telegraph, and helped others build the world's first English typewriter< In the spring of 1876, Edison moved to "Monroe Park" in New Jersey. He built the first "invention factory" here, which "marks the beginning of collective research". In 1877, Edison improved the telephone invented by Bell and put it into practical use. He also invented his favorite project, the phonograph. Telephone and Telegraph "is a revolution to expand human sensory function"; Gramophone is one of the three great inventions that changed people's lives. "From the perspective of invention imagination, this is his extremely important invention achievement.". By this time, people called him "the magician of Monroe Park"< When Edison invented the phonograph, he finally made a breakthrough in the research of electric lamp after numerous failures. On October 22, 1879, Edison lit the first electric lamp with wide practical value. In order to extend the life of the filament, he retested, and tried out more than 6000 kinds of fiber materials before finding a new luminous body, Japanese bamboo silk, which lasted for more than 1000 hours, and achieved a rable purpose. In a way, this invention is the highest achievement of Edison's life. Then he created a power supply system that allowed distant lamps to be distributed from a central power station, a major technological achievement
his first discovery in pure science appeared in 1883. When experimenting with electric lamps, he observed what he called the Edison effect: an electric charge in the lighted bulb passes through space from the hot filament to the cold plate. Edison patented the discovery in 1884, but did not study it further. Other scientists used the Edison effect to develop the electronic instry, especially radio and television
Edison tried to do what the phonograph did for the ear for the eye, and the film camera was born here. Using a new Celluloid film invented by George Eastman, he took a series of photos and projected them onto the screen quickly and continuously, creating the illusion of movement. He first experimented with films in the laboratory in 1889 and patented them in 1891. In 1903, his company proced the first feature film "train robbery". Edison did a lot of work for the formation and standardization of the film instry< After Edison moved his laboratory to West Orange in 1887, he founded many commercial companies to make procts and promote sales for his various inventions; These companies later merged into Edison General Electric Company, later known as general electric company. Since then, his interest has shifted to fluorimetry, ore crushers, magnetic separation of iron, batteries and railway signaling devices
ring the first World War, he developed torpedo mechanism, flamethrower and underwater periscope< On October 21, 1929, on the 50th anniversary of the invention of electric light, people held a grand celebration for Edison. Famous scientists such as Albert Einstein of Germany (Federal Republic of Germany) and Madame Curie of France (born in Poland) congratulated him one after another. Unfortunately, at this celebration, when Edison delivered his reply, he suddenly fainted e to excessive excitement. From then on, his health went from bad to worse. On October 18, 1931, the scientist who had made great contributions to mankind died of illness at the age of 84
Edison's ecation level is very low, but his contribution to mankind is so great. What's the "secret" here? In addition to a curious heart, he has an instinct to test himself, that is, he has the infinite energy and bold spirit of extraordinary hard work. When someone called Edison a "genius", he explained: "genius is one percent inspiration and ninety-nine percent perspiration." In the "invention factory", he organized many people of different professions, including more than 100 scientists, engineers, technicians and workers. Many of Edison's major inventions were successful thanks to this collective force. His achievements are mainly e to his hard work and creative ability, as well as the strength of the collective, in addition to his wife

5. Muffler is generally used in cars or guns to rece the noise of car exhaust pipe and the sound of guns shooting. In fact, it can only be said that it can be reced, but it can not be said that it can be completely eliminated. No muffler can be achieved unless there is no medium to transmit sound in a vacuum environment.
