Who are the mathematicians in China? There is a simple introduction. (both modern and ancient)

Zu Chongzhi calculated the value of pi to the seventh place after the decimal point for the first time in the history of mathematics in the world, that is, between 3. 14 15926 and 3. 14 15927. He put forward the agreement rate of 22/7 and the density rate of 355/ 1 13, which was the earliest in the world, and was 1 100 years earlier than that in Europe, so some people advocated calling it the "ancestor rate", which was the ancestor of pi. He compiled his mathematics research results into a book called Seal Characters, which was once regarded as a mathematics textbook by Chinese studies in the Tang Dynasty. His Da Ming Li introduced precession into the calendar for the first time. It is suggested that 39 1 year set 144 leap month. The length of a tropical year is 365.338+04438+0 days, and the error is only about 50 seconds. He is not only an outstanding mathematician and astronomer, but also an outstanding mechanic expert. Rebuild all kinds of exquisite machinery such as south guide car, thousand-mile ship and water hammer mill, which have long been lost. After years of calculation, he also compiled a new calendar, Daming Calendar. This was the most advanced calendar in the world at that time.

Qin Jiushao (1208- 126 1), an official and mathematician in the Southern Song Dynasty, was also called the four great mathematicians in the Song and Yuan Dynasties with Ye Li, Yang Hui and Zhu Shijie. The word Gu Dao, Han nationality, claimed to be from Lujun (now Qufu, Shandong) and Anyue, Zhou Pu (now Sichuan). He studies astrology, rhythm, arithmetic, poetry, bows and arrows and creation. He was a magistrate in Qiongzhou, a farmer and was later demoted. He died in Meizhou, where he wrote "Nine Chapters", in which the great derivative, the triclinic quadrature and Qin's algorithm are important contributions of world significance.

Liu Hui (about AD 225-295), a native of zouping county, was a great mathematician in Wei and Jin Dynasties and one of the founders of China's classical mathematical theory. He is a very great mathematician in the history of Chinese mathematics. His representative works "Nine Arithmetic Notes" and "Calculations on the Island" are China's most precious mathematical heritage. Liu Hui has quick thinking and flexible methods, and advocates both reasoning and intuition. He is the first person who China explicitly advocated to demonstrate mathematical propositions by logical reasoning. Liu Hui's life is a life of hard exploration of mathematics. Although he is in a low position, he has a noble personality. He is not a mediocre man who pursues fame and fortune.

Su, an academician of China Academy of Sciences and an outstanding mathematician in China, is known as the king of mathematics, and is also known as the "Three Kings of Pingyang" with Ma Xingye, the king of chess and news. Mainly engaged in differential geometry and computational geometry. Outstanding achievements have been made in the research of affine differential geometry and projective differential geometry, and in general space differential geometry, high-dimensional space conjugate theory, geometric shape design, computer-aided geometric design and so on. He was an academician of China Academy of Sciences, a member of several sessions of China People's Political Consultative Conference, a deputy to the National People's Congress, a member of the 5th and 6th the NPC Standing Committee, a vice-chairman of the 7th and 8th China People's Political Consultative Conference, a vice-chairman of NLD Central Committee and the president of Fudan University. Won the National Science Conference Award 1978.

Hua, a native of Jintan, Jiangsu Province, is an international master of mathematics and an academician of China Academy of Sciences. He is the founder and pioneer of analytical number theory, matrix geometry, typical group and self-safety function theory in China. He made unparalleled contributions to the development of mathematics in China. Known as "the father of modern mathematics in China", he is listed as "one of the 88 great mathematicians in the Chicago Museum of Science and Technology". Bateman, a famous American mathematical historian, said: "Hua is China's Einstein, enough to be an academician of all the famous academies in the world." . Mr. Hua's early research field was analytic number theory, and his achievements in analytic number theory were particularly famous. The internationally famous "China Analytic Number Theory School" is a school initiated by China, which has made many significant contributions to the distribution of prime numbers and Goldbach conjecture. His outstanding contributions to the theory of multiple complex variables and matrix geometry have influenced the development of mathematics in the world. There is also the internationally renowned "China Typical Group School". Mr. Hua's research on the theory of multiple complex variables and typical groups is ahead of the western mathematics field 10 years, and these research results have been highly praised by famous mathematicians in China. Mr. Hua is an unparalleled genius.
