Ask the story of Li Siguang.

ThomasAlvaEdison is a world-famous American electrician and inventor. In addition to his inventions and contributions in phonograph, electric light, telephone, telegraph and film, he also has many famous creations and opinions in mining, construction and chemical industry. Edison had about 2,000 inventions in his life, which made great contributions to the progress of human civilization.

Edison was born in1February, 847 1 1, Milan, Ohio, in the midwest of the United States. My father is descended from Dutch, and my mother is a primary school teacher, descended from Scots. When Edison was 7 years old, his father lost money in the tile business and his family moved to Grady Otterborg in the northern suburb of Huron, Michigan. Shortly after moving here, Edison suffered from scarlet fever and was ill for a long time. It is believed that this disease is the cause of his deafness. Edison went to school at the age of 8, but after only three months of study, he was dismissed as an "imbecile" by the teacher and kicked out of school. Since then, his mother has been his "mentor". Because of his mother's good educational methods, he took a keen interest in reading. He not only reads widely, but also reads all kinds of books. At the age of eight, he read the works of Shakespeare and Dickens, the most important playwrights in the English Renaissance, and many important historical books. By the age of nine, he could quickly read difficult books, such as Parker's philosophy of nature and experiment. 10 years old, he loved chemistry. At the age of 1 1, 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 the train, commuting between Port Huron and Detroit, Michigan. While selling newspapers, he also deals in fruits and vegetables. Whenever he is free, he goes to the library to read books. He bought an old printing press and began to publish his own weekly newspaper, The Herald. The first issue of this weekly is printed on the train. With the money he earned, he set up a chemistry laboratory on the baggage car. Unfortunately, once a chemical caught fire, he and his equipment were thrown out of the car. Another time, when Edison tried to board a freight train, a conductor grabbed him by the ear and helped him get on the train. This action led to Edison's lifelong deafness.

1862 In August, Edison rescued a dying boy on the train track with fearless heroism. The child's father is grateful for this, but he is willing to teach him telegraph technology because he has no money to reward him. Since then, Edison has forged an indissoluble bond with this mysterious new electric world and embarked on a scientific journey.

1863, Edison worked as a telecom operator in Stratford Hub Station, the main railway line. From 1864 to 1867, I worked as a telegraph operator in all parts of the central and western regions and lived a life similar to wandering. Footprints include Stratford, Adrian, fort wayne, Indianapolis, Cincinnati, Nashville, Tennessee, Memphis, Louisville and Huron.

1868, Edison came to Boston as a telegraph operator. In the same year, he obtained the first invention patent. This is a device for automatically recording votes. Edison thought that this device could speed up the work of Congress and would be very popular. However, a member of Congress told him that they had no intention to speed up the agenda, and sometimes voting was slow because of political needs. From then on, Edison decided never to make any inventions that people didn't need.

At the beginning of June 1869, he came to new york to look for a job. While he was waiting for a summons in the broker's office, a telegram broke down. Edison was the only person there who could repair the telegraph, so he got a better job than he expected. On June+10, 65438, he and Pop established "Pop-Edison Company", which specializes in scientific instruments for electrical engineering. Here, he invented "Edison Universal Printing Machine". He dedicated this printing machine to the manager of a big company on Wall Street. He wanted to charge 5000 dollars, but he didn't have the courage to say it. So he asked the manager to give a price, and the manager gave 40 thousand yuan.

Edison used the money to build a factory in Ward Street, Newark, New Jersey, which specializes in manufacturing all kinds of motors. He worked all night. He trained many capable assistants, and at the same time, he happened to meet diligent Mary, his first bride in the future. In Newark, he invented wax paper and mimeograph. From 1872 to 1875, Edison invented the two-pole and four-pole telegraph successively, and helped others to make the world's first English typewriter.

1in the spring of 876, Edison moved to Menlo Park, New Jersey again. He built the first "invention factory" here, which "marked the beginning of collective research". 1877, Edison improved the telephone invented by Bell and put it into practical use. He also invented the phonograph, one of his favorite projects. Telephone and telegraph "are a revolution to expand human sensory functions"; The phonograph is one of the three great inventions that have changed people's lives. "From the imagination of the invention, this is his extremely significant invention achievement." At this time, people called him "the magician of Monroe Park".

When Edison invented the phonograph, after numerous failures, he finally made a breakthrough in the study of electric lights. 1879, 10 year1October 22nd, Edison lit the first electric lamp with wide practical value. In order to prolong the life of the filament, he tried more than 6,000 kinds of fiber materials and found a new luminous body-Japanese bamboo filament, which can last for more than 1000 hours and achieve the purpose of durability. To some extent, this invention is the pinnacle of Edison's life. Then, he created a power supply system, which made the distant lights distribute electricity from the central power station, which was a great technical achievement.

His first discovery in pure science appeared in 1883. When testing the electric lamp, he observed what he called the Edison effect: in a lighted bulb, charge travels from the hot filament through space to the cold plate. Edison applied for a patent for this discovery in 1884, but did not study it further. Scientists nearby developed the electronic industry, especially radio and television, by using the Edison effect.

Edison tried to do for his eyes what the phonograph did for his ears, and the movie camera was born here. Using a piece of celluloid film newly invented by George Heasman, he took a series of photos and projected them on the curtain quickly and continuously, creating the illusion of movement. He experimented with movies for the first time in the laboratories of 1889 and 189 1. 1903, his company produced the first feature film great train robbery. Edison did a lot of work for the establishment and standardization of the film industry.

After Edison moved his laboratory to West Orange in 1887, he founded many commercial companies, manufactured products and popularized his various inventions. These companies later merged into Edison General Electric Company, which was later called General Electric Company. Since then, his interests have turned to fluorescence, ore mashers, magnetic separation of iron, storage batteries and railway signaling devices.

During World War I, he developed a torpedo device, a flamethrower and an underwater periscope.

1929 10 2 1 On the occasion of the 50th anniversary of the invention of electric light, people held a grand celebration for Edison, and famous scientists such as Einstein of Germany and Madame Curie of France congratulated him one after another. Unfortunately, at this celebration, Edison suddenly fainted because of excessive excitement when he gave a reply. Since then, his health has gone from bad to worse 193 1 year1October 18 The scientist who made great contributions to mankind died of illness at the age of 84.

Edison's cultural level is extremely low, but his contribution to mankind is so great. What is the secret here? In addition to curiosity, he also has an instinct to experiment by himself, that is, he has unlimited energy and courage to work hard beyond ordinary people. When someone called Edison a "genius", he explained: "Genius is 2% inspiration and 98% sweat." He organized many people of different professions in the "invention factory", including more than 65,438+000 scientists, engineers, technicians and workers. Many of Edison's great inventions were achieved by this collective force. His achievements are mainly attributed to his diligence, creativity and collective strength. In addition, his wife also played a very important role.

Li Siguang, formerly known as Li, 1889, was born in a poor family in Huanggang County, Hubei Province. He studied in a private school taught by his father Li Zhuohou since childhood. 14 years old, bid farewell to his parents and came to Wuchang alone to apply for higher primary schools. When filling in the registration form, he mistook the name column for the age column, wrote down the word "fourteen", then changed the word "ten" to "Li", followed by the word "light", and from then on he got the good name of "Li Siguang".

From 65438 to 0904, Li Siguang was selected to study in Japan because of his excellent academic performance. He accepted the Japanese revolutionary thought and became the youngest member of the Alliance led by Sun Yat-sen. Sun Yat-sen appreciated Li Siguang's ambition: "It is very good and ambitious for you to engage in revolution at such a young age." I also gave him eight words: "study hard and become a national use."

19 10, Li Siguang returned from Japan. After Wuchang Uprising, he was appointed as a member of the Ministry of Finance of Hubei Military Government, and was later elected as the Minister of Industry. After Yuan Shikai came to power, the revolutionaries were excluded, and Li Siguang left the motherland again to study at Birmingham University in England. 19 18, Li Siguang, who got his master's degree, decided to return to work. On the way, in order to understand Russia after the October Revolution, I also made a special trip to Moscow.

From 1920, Li Siguang served as a professor and head of the department of geology in Peking University, and from 1928, he went to Nanjing as the director of the Institute of Geology of Chinese Academy of Sciences and was elected as the president of geological society of china. He led students and researchers to travel in the wild all the year round and traveled all over the country. He has given lectures in Europe and America for many times, attended academic conferences and inspected geological structures.

1in the autumn of 949, shortly after the founding of New China, Li Siguang, who was abroad, was invited to become a member of the CPPCC. After getting the news, he immediately made preparations for returning to China. At this time, a friend in London called him and told him that the ambassador of the Kuomintang government in Britain had received a secret order to publicly declare that he refused to accept the position of CPPCC, or he would be detained. Li Siguang made a decisive decision and left London for France alone. Two weeks later, Xu Shubin of Li Furen received a letter from Li Siguang, saying that he had arrived in Basel on the Swiss-German border. The couple bought a boat ticket from Italy to Hong Kong in Basel and secretly set off for home in 1949 and 65438+February respectively.

Li Siguang, who returned to the embrace of New China, was entrusted with an important task, successively serving as Minister of Geology, Vice President of China Academy of Sciences, Chairman of the National Association for Science and Technology and Vice Chairman of Chinese People's Political Consultative Conference. Although he is old, he is still fighting in the front line of scientific research and national construction, and has made great contributions to China's geology, oil exploration and construction. 1958, Li Siguang came to China through the introduction of He Changgong and Zhang Jinfu, and became a communist fighter from a national Democrat. After 1960s, Li Siguang's health became worse and worse due to overwork, but he devoted himself to earthquake prediction, prediction and geothermal utilization with great enthusiasm and energy. 1971On April 29th, Li Siguang died of illness at the age of 82.
