Because Einstein was a great physicist and he played a vital role in the development of the field of physics, Yang Zhenning spoke highly of Einstein.

Einstein received a doctorate in philosophy from the University of Zurich. Einstein proposed the photon hypothesis and successfully explained the photoelectric effect. As a result, he won the Nobel Prize in Physics in 1921 and founded the special theory of relativity in 1905. Founded the general theory of relativity in 1915. Died on April 18, 1955, at the age of 76.

Einstein laid the theoretical foundation for the development of nuclear energy and ushered in a new era of modern science and technology. He is recognized as the greatest physicist since Galileo and Newton. On December 26, 1999, Einstein was selected as the "Great Man of the Century" by Time Magazine.

When he was 35 years old, he accepted an invitation from the German scientific community. Moved to Berlin. In August, World War I broke out. Although he lives in the birthplace of the war. Living surrounded by war advocates, he resolutely expressed his anti-war attitude.

Einstein still firmly participated in the organization's secret activities. In October, the German scientific and cultural circles, manipulated and instigated by militarists, issued the "Declaration of the Civilized World" to defend the aggressive war launched by Germany and advocated that Germany was above all else and that the whole world should accept "the true German spirit".

Ninety-three people signed the "Declaration", all of whom were prestigious scientists, artists, and pastors in Germany at the time. When Einstein was asked to sign, he flatly refused, but at the same time he resolutely signed his name on the anti-war "Letter to Europeans."

Einstein's achievements were very high. He proposed the theory that the universe is finite and unbounded, completed quantum theory, and made huge contributions to the development of human science.
