The story is like, Zu Chongzhi.
Zu Chongzhi (AD 429-500), a native of Laiyuan County, Hebei Province, was an outstanding scientist in the Southern and Northern Dynasties. He is not only a mathematician, but also familiar with astronomical calendar, machinery manufacturing, music and other fields, and is an astronomer.
Zu Chongzhi's main achievement in mathematics is the calculation of pi, which is 3. 14 15926.
There's some information,
Hua
Hua, a modern mathematician in China. 19101012 was born in Jintan county, Jiangsu province. 1June 1985 12 died in Tokyo, Japan. After graduating from junior high school, Hua 1924 studied in Shanghai China Vocational School for less than one year. He dropped out of school because of his poor family. He studies mathematics hard. 1930 He published an article on solving algebraic equations in Science, which attracted the attention of experts. He was invited to work in Tsinghua University and began to study number theory. 1934, became a researcher of China Education and Culture Foundation. 1936 went to Cambridge University as a visiting scholar. 1938 returned to China and was employed by Professor The National SouthWest Associated University. 1946 was invited by the Institute of Advanced Studies in Princeton, Soviet Union as a researcher and taught at Princeton University. From 65438 to 0948, he was a professor at the University of Illinois.
After returning to China from 65438 to 0950, he successively served as Professor Tsinghua University, Head and Vice President of the Department of Mathematics of China University of Science and Technology, Director of the Institute of Mathematics of China Academy of Sciences, Director of the Institute of Applied Mathematics of China Academy of Sciences and Vice President of China Academy of Sciences. Hua is also a member of the first, second, third, fourth and fifth sessions of the NPC Standing Committee and vice chairman of the National Committee of the Sixth China People's Political Consultative Conference.
Hua is an internationally famous mathematician. He has made outstanding contributions in a wide range of mathematical fields, such as analytic number theory, matrix geometry, theory of multiple complex variables and partial differential equations. Because of his contribution, many theorems, lemmas, inequalities and methods are named after him. In order to promote the optimization method, Hua personally led a small team to 27 provinces to promote the application of mathematical methods for more than 20 years, which achieved obvious economic and social benefits and made great contributions to China's economic construction.
