Einstein was born in Germany on March 1879. Later, after entering a university in Switzerland, he became a Swiss citizen directly. After finishing university in Switzerland, he directly published a paper on thermodynamics.

At the same time, he also published quantum theory, and later put forward the light quantum hypothesis, which solved the problem of photoelectric effect. After receiving his doctorate, Einstein worked directly in the patent office. After returning to Germany, Einstein worked as a professor at the Kaiser Wilhelm Institute of Physics in Berlin and Humboldt University in Berlin.

When World War I broke out, Einstein resolutely opposed the war. 191511In June, Einstein put forward the complete form of the gravitational equation of general relativity, and later put forward the hypothesis that the universe is finite and unbounded.

During this period, after marrying a college classmate, they had a daughter before marriage. But after the divorce, Einstein married his cousin elsa. 192 1 year, Einstein won the nobel prize in physics for his research on photoelectric effect.

Later, when Einstein came to the United States, he became an American citizen and opposed the anti-fascist war. 1952, Einstein published Relativity and Space Problems and Introduction to Some Basic Introduction.
