He won the 192 1 Nobel Prize in Physics for his "contribution to theoretical physics, especially the discovery of the principle of photoelectric effect". This discovery is a key step in the establishment of quantum theory.
Early in his career, Einstein discovered that classical mechanics and electromagnetic fields could not coexist, thus developing special relativity. He also found that the principle of relativity can be extended to the modeling of gravity field. According to some developed theories of gravity, he published his general theory of relativity in 19 15.
He continued to study statistical mechanics and quantum theory, which enabled him to give explanations of particle theory and molecular motion. 19 17, Einstein established a large-scale structural universe model by applying general relativity.
Einstein was one of the most important scientists in the 20th century. He published more than 300 scientific papers and 150 non-scientific works in his life, and was known as "the father of modern physics". His outstanding and unique scientific achievements made the word "Einstein" synonymous with "genius".

The early correspondence between Einstein and mileva was discovered and published in 1987, which revealed that they had a daughter named Lise before they got married. . At the beginning of 1902, Liselle was born in Novi Samileva, Serbia. Mileva didn't take Richie back to Switzerland, and Richie's fate is still unknown.
Einstein may have never met Lizzy. In a letter written to mileva in September 1903, Einstein mentioned her for the last time, suggesting that the baby girl might be adopted or die of scarlet fever.
Einstein put forward two basic postulates of the special theory of relativity in the article Electrodynamics of Moving Objects: "the speed of light is constant" and "the principle of relativity".
According to these two basic postulates, when the speed of motion is close to the speed of light, some important amendments are made to classical mechanics, thus solving the contradiction between Maxwell's equations and the laws of classical mechanics. After finishing, these pioneering works became Einstein's special theory of relativity.
