Albert Einstein (Jewish physicist. He graduated from ETH Zurich in 1900 and became a Swiss citizen. In 1905, he received a doctorate in philosophy from the University of Zurich, and Einstein proposed the photon hypothesis and successfully explained the photoelectric effect, so he was awarded the Nobel Prize in Physics in 1921, and in the same year, he founded the special theory of relativity.

In 1915, he founded the general rough theory of relativity.

Einz Honettan laid the theoretical foundation for the development of nuclear energy, created a new era of modern science under the profound influence and wide application of modern science and technology, and is recognized as the greatest physicist since Galileo and Newton. On December 26, 1999, Albert Einstein was selected by Time Magazine as a Rock Sock Pure"The great man of the century"。

Deng Jiaxian He is mainly engaged in the research of nuclear physics, theoretical physics, neutron physics, plasma physics, statistical physics and fluid mechanics and has made outstanding achievements. Since 1958, he has organized and led the basic theoretical research on detonation physics, fluid mechanics, equation of state, neutron transport, etc., and conducted a large number of simulation calculations and analyses on the physical process of the atomic bomb, thus taking the first step in China's independent research and design of nuclear weapons, leading the completion of the theoretical program of China's first atomic bomb, and participating in the detonation simulation test before the nuclear test. After the successful test of the atomic bomb, he immediately organized forces to explore the design principles of the hydrogen bomb, selected technical methods, and organized, led, and personally participated in the development and testing of China's first hydrogen bomb in 1967.

In 1979, Deng Jiaxian served as the president of the Nuclear Research Institute. In 1984, he directed China's second-generation new nuclear test in the depths of the desert. The following year, his cancer spread beyond cure, and his request on National Day was to visit Tiananmen Square.

On July 16, 1986, Li Peng, then vice premier, went to the hospital to award him the National "May Day" Labor Medal. On July 29, 1986, Deng Jiaxian died of illness.
