2. After the special theory of relativity was put forward 10 and 19 15 years ago, Einstein established the general theory of relativity, and deduced that light propagates along a curve in the gravitational field. Although it was only predicted, it was confirmed by astronomers in 19 19 and caused a sensation in the scientific community.
Einstein also had a great influence on later generations in quantum theory. The photoelectric effect and wave-particle duality that many students learned were revealed by him through various experiments. In addition, Einstein's stimulated radiation theory laid a solid theoretical foundation for the development of laser technology.
Einstein had frequent wars all his life, so he also contributed to the maintenance of world peace in his lifetime. Knowing the harm of nuclear weapons, he voluntarily withdrew from the field of nuclear physics research and strongly opposed the use of nuclear weapons in war.
The story of Einstein
Childhood: Knocked a hole in my sister's head?
When Einstein was born in March 1879, the back of his head was surprisingly large and angular, and his mother thought it was a deformed baby. I'm two and a half years old, and I can't speak yet. One day, a little sister riding a bicycle came home. He said a complete sentence: Yes, but what about her little wheel? When I was 5 years old, I was manic, scared away the tutor and knocked a "big hole" on my sister's head with a children's hoe.
