What is the development level of mathematics in Song Dynasty in real history? What is the scene of engineering technology?
Although the Song Dynasty was weak in force and its territory was occupied by many people, its achievements in mathematics were widely publicized in history books, and the Song and Yuan Dynasties were even regarded as a climax of the development of mathematics in China. Looking back, the development achievements of mathematics in Song Dynasty laid the foundation of Tang Dynasty. At that time, the commercial trade of the Silk Road was booming, and people demanded more and more applications of computing. Some fast algorithms have been proposed to convert multiplication and division into addition and subtraction.
Among the mathematicians in the Northern Song Dynasty, Jia Xian was once a small military attache of the straight left class, with a low rank, but he made great achievements in mathematics. He studied with Chu Yan, a famous astronomer and mathematician at that time, summarized the specific mathematical problems in previous mathematical works, and put forward many new mathematical methods, including Jia Xian Triangle, multiplication and division, etc. Shen Kuo, a great scientist, also pioneered the use of gap product method to solve the problem of higher-order arithmetic progression summation in Meng Qian Bi Tan.
During the Southern Song Dynasty, there were two mathematical centers, North and South. South China is represented by Qin and Yang Hui, while North China is represented. Zhu Shijie, after the Yuan Dynasty unified China, was the combination of two mathematical centers, which reached the highest level of China calculation.
Qin is very talented. He is proficient in mathematics, astronomy, civil architecture, poetry, temperament, bow and horse, etc.
He repeatedly called on the rulers to be benevolent, and regarded mathematical knowledge as a powerful tool to increase revenue and reduce expenditure and benefit the country and the people.
However, in his official career, he was inevitably involved in the ruling clique war and the dispute between the two factions in the Southern Song Dynasty. Qin had a deep friendship with the envoys of the Tang Dynasty, and advocated using force to resist Mongolia. He was vilified as? Ruthless, unfilial and dishonest? Public opinion also attacked him a lot, and the history of Song Dynasty and all local chronicles did not make a biography for him after his death. However, this does not prevent Qin from going down in history in the world. American historian of science Sutton said: "Qin is one of the greatest mathematicians in his country, his time and even all times."
