1, Liu Hui (about 225-295), Han nationality, born in Zouping, Binzhou, Shandong Province, 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 "Arithmetic on the Island" are China's most precious mathematical heritage.
Liu Hui has quick thinking and flexible methods. He advocates reasoning and intuition.
He was the first person in China who explicitly advocated using logical reasoning to demonstrate mathematical propositions.
Liu Hui's life is a life of hard exploration of mathematics.
Although his position is low, his personality is noble.
He is not a mediocre man who seeks fame and fame, but a great man who never tires of learning. He left us a valuable fortune.
2. Zhao Shuang, also known as Ying, is a mathematician in China.
Wu people from the end of the Eastern Han Dynasty to the Three Kingdoms period.
He is a famous mathematician and astronomer in the history of our country.
Life span is unknown, about 182-250 years.
3. Zu Chongzhi (429-500), born in Jiankang (now Nanjing), was originally from Qixian County, Fanyang County (now Laishui County, Hebei Province). He was an outstanding mathematician and astronomer in the Southern and Northern Dynasties.
Zu Chongzhi studied natural science all his life, mainly contributing to mathematics, astronomical calendar and mechanical manufacturing.
On the basis of exploring the accurate method of pi pioneered by Liu Hui, he first calculated the "pi" to the seventh place after the decimal point, that is, between 3. 14 15926 and 3. 14 15927. His "ancestral rate" has made great contributions to mathematical research.
It was not until16th century that Al Cassie, a mathematician of * *, broke this record.
4. Shen Kuo (103 1 year-1095), Meng Qian, Han nationality, born in Qiantang County, Hangzhou, Zhejiang Province, was a politician and scientist in the Northern Song Dynasty.
Shen Kuo devoted himself to scientific research all his life, and had profound attainments and outstanding achievements in many disciplines. He is known as "the most outstanding figure in the whole history of science in China".
His masterpiece Meng Qian Bi Tan is rich in content and a great achievement of predecessors. It plays an important role in the world cultural history and is called "a milestone in the history of science in China".
5. Qin (1208- 1268), born in Lujun (now Fanxian County, Henan Province), Han nationality.
? [1] A famous mathematician in the Southern Song Dynasty, together with Ye Li, Yang Hui and Zhu Shijie, is called the four great mathematicians in the Song and Yuan Dynasties.
He studies astrology, rhythm, arithmetic, poetry, bows and arrows and architecture. He was a magistrate in Qiongzhou, a farmer and was later demoted. He died in Meizhou, where he completed 1247' s Shu Shu Jiu Zhang, in which the major deduction is a technique (solution of congruence equations, now called China residue theorem) and triple oblique quadrature.
