Chinese celebrities – Zu Chongzhi
Zu Chongzhi (429-500 years), written by Wenyuan, was born in Qiuxian County, Fanyang County (now Laishui County, Hebei Province), and was an outstanding mathematician and astronomer during the Northern and Southern Dynasties. Born in Fan Yang Zu clan. He has studied natural sciences all his life, and his main contributions are in mathematics, astronomical calendar, and mechanical manufacturing. Based on Liu Hui's precise method of exploring Pi, he actuated the "pi" to the seventh decimal place for the first time, that is, between 3.1415926 and 3.1415927. The "Zu rate" he proposed has a significant contribution to the study of mathematics. It was not until the 16th century that Arab mathematician Al Qassim broke this record. The "Da Ming Calendar" written by him was the most scientific and advanced calendar at that time, and it provided a correct method for astronomical research in later generations. His main works include "A Bian Lun", "Zhu Shu", "Shu Yi Ji", "Lian Yi" and so on. Main influence Mathematics A Pioneering Work in the History of Mathematics-"Zu Shi" Zu Chongzhi calculated that the true value of Pi (π) is between 3.1415926 and 3.1415927, which is equivalent to the 7th decimal place, simplified to 3.1415926.
