Brief introduction to the essence of Einstein

Einstein was born in Ulm, Germany in p>1879. Einstein's father is a businessman. He owns a factory that produces electrical equipment. As a child, Einstein was very quiet, and he often killed time alone. He is slow in language expression and has difficulty in reading. However, he is particularly interested in the principle of things and often asks many questions.

Einstein didn't like going to school because the schools in Germany at that time didn't allow students to ask questions. Einstein said that he had a feeling of being in prison. Einstein once told his uncle Jacob that he hated mathematics, especially algebra and geometry. However, his uncle Jacob gave him vivid inspiration, which brought great changes to his lessons. Einstein finished all the exercises in the algebra book. While other students are still studying elementary mathematics, he has already studied calculus. Einstein decided to be a math and physics teacher.

Einstein studied at Zurich Federal Institute of Technology and graduated with honors. However, he couldn't find a job as a teacher, and later, he worked in the patent office of the Swiss government. The work in the patent office was easy, so he spent a lot of time creating his own theory. Some of them are theories about relativity.

In p>195, Einstein published a paper, which was only 35 pages, but it was one of the most important documents in the history of science. This is the special theory of relativity. Some theories of relativity seem unbelievable, but experiments show that they are completely correct. Special relativity is some basic theories used to describe natural phenomena, and it is a theory about time, space, mass, motion and gravity.

ten years after he published his paper on special relativity, Einstein published another paper-general relativity, which put forward a new argument about the relationship between gravity, matter and energy.

Einstein proposed that matter can be converted into energy, and he also gave an expression that can measure the energy of matter-e = mc2. E represents the energy of matter; M represents the mass of matter; C is the speed of light. This expression shows that very small matter can produce great energy. This formula also led to the discovery of atomic energy.

Einstein won the Nobel Prize in Physics in 1921. He won the prize not because of the theory of relativity, but because he discovered the law of photoelectric effect. This discovery promoted the development of modern electronics, including radio and television.

In p>1933, Einstein left Germany when Hitler came to power. He wants to live in a country with political freedom, tolerance and equality under the law. Einstein came to America to continue his research work.

Einstein spent the last 25 years of his life in the study of "unified field theory". He hopes to find a general mathematical formula that links all the fields of physics. Einstein never finished this work.

Einstein died in p>1955 at the age of 76.
