On this day, 112 years ago, October 16, 1913 (September 17, 1913, the lunar calendar), Qian Sanqiang, the founder of China's "two bombs and one satellite", was born. Qian Sanqiang (October 16, 1913-June 28, 1992) Qian Sanqiang, a nuclear physicist in China. Born on October 16, 1913. He is from Wuxing, Zhejiang. Graduated from Tsinghua University in 1936, went to France to study in 1937, and worked in the Curie Laboratory of the Institute of Radium Sciences at the University of Paris. In 1940, he received his doctorate from the French National Center for Scientific Research. In 1944, he served as a researcher and research supervisor at the French National Center for Scientific Research. In 1946, he was awarded the Debawe Prize from the French Academy of Sciences. After 1950, he successively served as director and secretary-general of the Planning Bureau of China Academy of Sciences, deputy director of the Institute of Modern Physics, director of the Institute of Atomic Energy, vice president of China Academy of Sciences, president of Zhejiang University, and member of the Department of Physics and Chemistry. From 1938 to 1939, he collaborated with Irene Curie and discovered that uranium and thorium were fissured to obtain the same fission product, namely the isotope of lanthanum. In 1944, he first calculated the relationship between the range and energy of weak energy electrons and obtained them. Relationship curve between them. His reasonable explanation for the triple division of uranium is recognized by the physical community of various countries. He organized the Beijing Fundamental Particle Theory Group and created the "stron model" of elementary particles in 1966. He made outstanding contributions to the development of atomic energy science in China and the cultivation of atomic science and technology talents. Zhou Enlai proposed a toast to Qian Sanqiang In the spring of 1948, Qian Sanqiang took a photo with Jorio Curie and his wife in Paris on the eve of his return to China.
