On July 7th, 1937, the shots of the Lugouqiao Incident rang out. Twenty-two days later, Beiping fell. The Japanese invaders held a "celebration". 13-year-old Deng Jiaxian can't stand this humiliation. He tore a Japanese flag to pieces in public, threw it on the ground and stepped on it. After this incident, a friend of Deng Yizhe advised him that it would be reported sooner or later, so you'd better let the children leave Beiping as soon as possible.

In desperation, Deng Yizhe asked Deng Jiaxian's sister to take him south to Kunming, while Tsinghua and Peking University professors moved south, and many old friends were in Kunming. Before he left, his father said to him, "Jiaer, you must study science instead of literature in the future." Science is useful to the country. " Deng Yizhe pinned his hopes on Deng Jiaxian according to his own experience, but this sentence left a deep impression on Deng Jiaxian's mind.

Major achievements

Deng Jiaxian is one of the founders of China's theoretical research on nuclear weapons. He is the main organizer and leader of China's nuclear weapons research and development, and is known as the "father of the two bombs". In the research of atomic bomb and hydrogen bomb, Deng Jiaxian led the basic theoretical research of detonation physics, fluid mechanics, equation of state and neutron transport, completed the theoretical scheme of atomic bomb, and participated in guiding the detonation simulation test of nuclear test.

Deng Jiaxian not only attached importance to scientific experiments, but also paid special attention to sorting out and summarizing scientific theories in time. Deng Jiaxian and Zhou He wrote A Summary of Theoretical Research on China's First Atomic Bomb.

It is a groundbreaking masterpiece on the theoretical design of nuclear weapons, summarizing the research results of hundreds of scientists. This work is not only instructive for future theoretical design, but also an introductory textbook for training researchers.
