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.
The God of Mathematics-Archimedes
King Shiloh of Syracuse asked the goldsmith to make a crown out of pure gold. Because it was suspected that there was silver in it, Archimedes was asked to identify it. When he entered the bathtub to take a bath, the water overflowed outside the bathtub, so he realized that although the weight of objects made of different materials was the same, the discharged water would be different because of their different volumes. According to this truth, it can be judged whether the crown is adulterated. Archimedes jumped up with joy and ran home naked, shouting, "Found it! Eureka "[Greek enrhka, meaning" I found it "] He summed up the basic principle of hydrostatics in his famous book" On floating bodies ",that is, the weight of objects in liquid is equal to the weight of discharged liquid, and later became famous for Archimedes principle.
In 2 12 BC, Roman troops invaded Syracuse and broke into Archimedes' house. They saw an old man burying his head in the ground into a geometric figure, and the soldiers trampled it down. Archimedes angered the soldiers: "Don't break my picture! The soldier drew his dagger and stabbed the great scientist, but Archimedes died at the hands of stupid and ignorant Roman soldiers.
