He studied astronomy, calendar, mathematics, surveying and mapping, water conservancy and other western science and technology from Matteo Ricci earlier, and devoted himself to the research of science and technology all his life and worked hard to write. He is an active promoter of introducing and absorbing European science and technology, and has made important contributions to the cultural exchange between China and the West in the17th century.
2. Wang Xun:
Xun Wang, Zi Jingfu, born in Tang County, Zhongshan, was a mathematician in Yuan Dynasty. He studied mathematics and astronomy under Liu, and then studied mathematics and astronomical calendar under Liu Guo Shoujing, and was proficient in calendar calculation. In Taishi's post, Wang Xun was responsible for astronomical observation and calculation, and studied more than 40 almanac books.
3. Zu Chongzhi:
Zu Chongzhi was born in Fan Yangzu's family. He 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 calculated pi to the seventh place after the decimal point for the first time.
That is, between 3. 14 15926 and 3. 14 15927, his "ancestral rate" has made great contributions to the study of mathematics. It was not until the 6th century A.D./KLOC-that the Arab mathematician Al Cassie broke this record.
4. Zhao Shuang:
