1, Einstein's scientific achievements
Einstein's most important scientific achievements are relativity, 1905' s special relativity and 19 16' s general relativity. In addition, 1926 "photoelectric effect" won the Nobel Prize, and he also proposed cosmology and unified field theory.
Compared with Newton, Newton's classical mechanics studies the low-speed motion of macroscopic objects, while Einstein's theory of relativity studies the high-speed motion of microscopic objects. The speed of motion is not constant, but changes with time and space.
2. Einstein's life
Einstein was born in 1879 and died in 1955. Since childhood, he likes to study problems and get to the bottom of them.
In Einstein's autobiography, there is a "compass story". Later, Einstein recalled that experience and left a deep and lasting impression on him. There must be something deep behind it. After reading the series of natural science popularization in middle school, Einstein claimed that it was a good book, which had a great influence on his future development. It was also the Alau Middle School in Switzerland where he attended that advocated internationalism and peace and insisted on freedom, which laid the foundation for Einstein's theory of relativity. Einstein's university, Swiss Federal Institute of Technology Zurich, has a good reputation for engineering and likes to challenge authority, which provides conditions for Einstein to engage in research.
3. Einstein's evaluation
In science, Einstein inherited and developed Newton's classical mechanical system, especially the general theory of relativity, and demonstrated the distribution and motion relationship of matter in the four-dimensional space of the universe for the first time, making great contributions to the development of modern science.
During the two world wars, Einstein signed an anti-war declaration to enhance understanding among countries and made unremitting efforts to promote world peace. At the same time, in order to prevent nuclear war, he first suggested developing an atomic bomb.
To sum up, we can see that Einstein is not only the mystery of the atom and the universe, but also a deep concern for mankind, happiness and freedom. Few scientists in the 20th century can surpass Einstein's contribution to modern science and world peace.
