[edit] Life

Cheng was born in Wujiang, Jiangsu Province (currently Shanghai) in 1918. He graduated from the Department of Physics, Zhejiang University in 1941. 1946, he went to Britain and studied in the University of Edinburgh, and obtained PhD in 1948 (advisor: Max Born). Then he became a researcher in UK.

Cheng returned China in 1950. He was an associate professor at Zhejiang University, then he went to Nanjing, became an associate professor in Nanjing University. Afterward he was promoted to full professorship in Nanjing University.

Cheng was a pioneer of Chinese nuclear technology and played an important role in the development of the first Chinese atomic bomb. He first calculated out the inner temperature and pressure for an antomic bomb blast in China. His calculation was an extremely heavy task and nearly manual, because during that time China didn't have any computer or less calculator. He also solved the mechanism of the inner explosion, which could support the design of the bomb. He was the chief director for many nuclear weapon test fields/bases and their explosion processes. [2]

Cheng was elected to be an academician of the Chinese Academy of Science. He was also a Standing Member of the Science and Technology Committee, Chinese National Nuclear Industry Corporation. He was former Vice-President of the Nuclear Weapons Research Institute, and the Deputy Chief Director of the Nuclear Weapons Research Institute, People's Republic of China. [3]
