Einstein put forward three epoch-making theories: light quantum hypothesis, special relativity and statistical explanation of Brownian motion. As a result of confirmatory experiments, several great scientists who did not believe in the existence of atoms at that time turned to believe. Since then, Einstein mainly attacked his higher goal-general relativity, and finally gave the basic framework of general relativity at the age of 37.
Edison invented the phonograph, movie camera and electric light, which had a great influence on the world.
Edison was the first scientist in human history who used a large number of production principles and electrical engineering research laboratories to patent inventions. He had more than 2,000 inventions and 1000 patents in his life.
