Albert Einstein, the greatest physicist in the 20th century, was born in Ulm, southwest Germany, on March 1879, and moved to Munich with his family a year later. Einstein's parents were Jews. His father Herman Einstein and his uncle Jacob Einstein jointly opened an electrical appliance factory to produce motors, arc lamps and electrical instruments for power stations and lighting systems. Mother Pauline, a housewife with secondary education, likes music very much and taught Einstein to play the violin when he was six years old.

Einstein should not be vain before his death, let alone mourn after his death. He left a will asking for no obituary and no funeral. He gave his brain to medical research, cremated his body, and secretly scattered his ashes in a river that no one knew. He doesn't want a grave or a monument. When his body was sent to the crematorium for cremation, only his closest 12 people accompanied him, and no one else knew the time and place of cremation.

Before Einstein died, he left his house on Merseyside Street 1 12 in Princeton to Miss Ducas, his secretary who had worked with him for decades, and stressed: "Don't turn this house into a museum." He doesn't want to turn Merseyside Street into a pilgrimage site. He has never worshipped idols in his life, and he doesn't want future people to regard him as an idol.

Einstein once said, "I am only a small part of nature". He dedicated everything to the journey of human freedom from nature, and finally even his ashes returned to the embrace of nature. But just as Infield felt when he first came into contact with him: "True greatness and true nobility always walk side by side", Einstein's great achievements and spirit have been left to mankind.

Einstein's truancy

1895 spring, Einstein 16 years old. According to the laws of Germany at that time, only when the boy left Germany before the age of 17 could he not have to come back for military service. Because he hated militarism and couldn't bear to stay in the barracks alone-just like Louis Polder Middle School, Einstein decided to leave Germany and go to Italy to reunite with his parents without consulting his parents.

However, what if I drop out of school and can't get my diploma later? Einstein, who has always been honest and simple, came up with a self-righteous idea in a hurry. He asked the math teacher to give him a certificate to prove that his math scores were excellent and he reached the university level early. I got a sick note from a familiar doctor, saying that it was neurasthenia and I needed to go home and rest. Einstein thought that with these two proofs, he could escape from this disgusting place.

Who knows, before he applied, the dean called him and ordered him to drop out of school on the grounds that he corrupted the class spirit and disobeyed the school discipline.

Einstein blushed. For whatever reason, he was willing to leave this middle school and didn't care about anything. He just suddenly felt guilty that he had come up with a cunning idea but it didn't come true. Einstein felt guilty every time he mentioned it later. Perhaps this kind of thing is far from his frank and sincere personality.

Mr Weber's eyes

At the age of sixteen, Einstein applied for the engineering department of the Federal Institute of Technology in Zurich, Switzerland, but failed in the entrance examination. Mr. Weber, a physicist, read his papers on mathematics and physics. He was very discerning and praised him: "You are a very clever boy, Einstein, a very clever boy, but you have a big shortcoming: you don't want to show yourself."

Mr Webber is right. Einstein is a "genius" in mathematics. He taught himself analytic geometry and calculus at the age of 12 to 16. He is also "unrepentant" for not wanting to show his "shortcomings". In his letter to friends in his later years, he said: "When I was young, my needs and expectations for life were that I could do research quietly in a corner, and the public would not pay full attention to me, but now I can't."

Charlie Chaplin, a famous film actor, invited Einstein and his wife to the movies on the day of the premiere of his film City Lights in Hollywood. When Einstein and Chaplin got off the bus, many people found Einstein coming to the theater. Everyone gathered around and cheered, focusing on him instead of Chaplin. Einstein didn't like this scene and asked Chaplin, "What does this mean?" Chaplin immediately comforted him: "Nothing."

This is how the theory of relativity was discovered.

Mrs Einstein once told Charlie Chaplin about Einstein's work when he discovered the theory of relativity. Later, Chaplin recorded this in his autobiography. This story shows how Einstein worked at this historic moment of discovery:

"As usual, the doctor went downstairs to have breakfast in his robe, but nothing moved that day. I think something must have happened. I asked him what made him's spaced out.

He replied, "dear! I have a clever idea. "

After drinking coffee, he went to the piano and began to play. Stop several times to record something on paper, and then repeatedly say, "I have a clever idea, a wonderful idea."

He said, "It's hard. I still need to work."

He continued to play the piano and wrote for half an hour. Then he went upstairs to his research room and told me not to disturb him. He stayed in the house for two weeks. Every day I go upstairs to feed him. In the evening, he took a walk as exercise, and then came back to continue his work.

At last he came downstairs, pale. "This is my discovery!" He put two pieces of paper on the table, which is his theory of relativity. "

Secret of success

Theological research

Einstein devoted the last 30 years of his life to theological research. trait

1879, Albert Einstein was born into a Jewish family in Ulm, an ancient city in southwest Germany. Father is the owner of an electronics store. My mother is a versatile pianist.

1880, he moved to Munich with his family and spent his childhood there. It seems that he developed slowly and began to speak at the age of three, so he was considered a slow-witted child. Until middle school, some teachers thought that he would not succeed when he grew up. When he was six, his mother taught him to learn the violin. When he was fourteen, he could play on the stage. The violin accompanied him all his life.

At the age of ten, Einstein entered Munich missionary middle school. However, his basic knowledge comes from family and self-study. In middle school, he was poor in all subjects except mathematics, so he was expelled from school at 1894. In the same year, he left Germany and went to Zurich to study at 1895, but he was not admitted and had to transfer to a middle school. The following year, he was admitted to the Normal Department of Federal Institute of Technology to study physics. During his four years in college, his main focus was not on formal courses, but on self-learning some famous books. Even though he seldom attends classes, he can still get a passing grade by taking class notes from his classmates.

Einstein graduated from 1900. Because the academic performance is not outstanding, I can't find a teaching position.

1902, Einstein finally found the position of examiner in the federal patent office in Bern. At this time, he continued to teach himself theoretical physics in his spare time.

In the year from 65438 to 0905, 26-year-old Einstein published four great papers, which were the most creative in all fields of physics. The article "A New Method for Determining Molecular Volume" (on Brownian Motion) earned him a Ph.D. degree from the University of Zurich, while the article "Inspiring Views on the Generation and Transformation of Light" (on photoelectric effect) earned him the 192 1 year Nobel Prize in Physics. The other two articles established the special theory of relativity, which was regarded as his most important contribution to physics by later generations.

19 13 years, Planck and Nernst invited Einstein to work in Germany on behalf of Prussian Academy of Sciences.

19 14 years, director of the Institute of Physics of William the Great, professor of Berlin University. This teaching position gave Einstein financial support, which enabled him to engage in research all the time.

19 16 years, Einstein published The Basis of General Relativity, which is the first complete paper on general relativity and a summary of this work.

From 65438 to 0933, persecuted by Nazi Germany, Einstein moved to the United States and became a professor at Princeton Institute for Advanced Studies.

1940 Obtaining American citizenship.

1955 died in Princeton.
