Brief introduction and deeds of Einstein, within 200 words

Albert Einstein (March 14, 1879 - April 18, 1955) was born in Ulm, Kingdom of Württemberg, Germany. He graduated from the Federal Institute of Technology in Zurich. College, Jewish physicist.

Einstein was born in 1879 in a Jewish family in Ulm, Germany (both parents were Jewish). He graduated from the Federal Institute of Technology in Zurich in 1900 and became a Swiss citizen. In 1905, Einstein received a doctorate in physics from the University of Zurich. He proposed the photon hypothesis and successfully explained the photoelectric effect, for which he won the 1921 Nobel Prize in Physics.

He founded the special theory of relativity in 1905 and the general theory of relativity in 1915. He immigrated to the United States in 1933 and worked at the Institute for Advanced Study in Princeton. In 1940, he became an American citizen while retaining Swiss citizenship. Einstein died in Princeton, New Jersey, USA on April 18, 1955, at the age of 76.

Einstein’s theory laid the theoretical foundation for the development of nuclear energy. In order to help fight against the Nazis, in 1939, with the assistance of Leo Szilard and others, he wrote to U.S. President Franklin Roosevelt, directly promoting the After World War II, he actively advocated peace, opposed the use of nuclear weapons, and signed the Russell-Einstein Declaration.

Einstein ushered in a new era of modern science and technology and is recognized as the greatest physicist after Galileo.

In December 1999, Einstein was selected as the "Person of the Century" in the 20th century by Time Magazine.

Extended information:

In the spring of 1895, Einstein was 16 years old.

According to German law at the time, boys did not have to return to serve in the military unless they left Germany before the age of 17. Due to his deep hatred of militarism and the fact that he could no longer bear to be alone in the military-like Luipold High School, Einstein decided to leave Germany without consulting his parents and reunite with his parents in Italy. However, what should I do if I drop out of school and cannot get a diploma in the future? Einstein, who had always been honest and simple, came up with an idea that he thought was a good one in desperation. He asked his math teacher to give him a certificate saying that he had excellent math scores and had already reached the university level.

He also got a sick leave certificate from a familiar doctor, saying that he had a nervous breakdown and needed to go home to rest. Einstein thought that with these two proofs, he could escape from this disgusting place.

Unexpectedly, before he applied, the dean of students called him in and ordered him to drop out of school on the grounds that he had ruined the class spirit and failed to abide by school discipline. Einstein blushed. No matter what the reason was, as long as he could leave this middle school, he was willing to do so and didn't care about anything else.

He just suddenly felt guilty for having come up with a cunning idea that he never implemented. Later, Einstein felt guilty every time he mentioned it. Perhaps this kind of thing is too far away from his frank and sincere personality.
