Historically, the government joined the army, Lou County (now the northeast of Kunshan City) ordered, servant shot, a captain of Changshui and other official positions. His main contributions are in mathematics, pi, astronomical calendar and machinery. He has made outstanding contributions to the progress of China and even the world civilization.
His achievements in mathematics are:
His book Composition was included in the famous Ten Books of Calculating Classics, which was used as a teaching material for imperial academy in the Tang Dynasty, but it was later lost. There is a brief record of pi in the Book of Rites of Sui Dynasty. The true value of pi calculated by Zu Chongzhi is between 3. 14 15926 and 3. 14 15927, which is equivalent to being accurate to the seventh place after the decimal point and simplified to 3. 1465438+. Zu Chongzhi was selected as the first scientist in the world record association world to calculate the value of pi to the seventh place after the decimal point, which created the most in the China Society. This record was not broken by Arabian mathematician Cassie until15th century.
Zu Chongzhi also gave two fractional forms of π: 22/7 (approximate rate) and 355/ 1 13 (secret rate), in which the secret rate was accurate to the seventh place after the decimal point, and it was not rediscovered by the Dutch mathematician Otto until the west16th century. Zu Chongzhi, together with his son Zuxuan, successfully solved the problem of calculating the volume of the ball by using "Mu He Fang Gai" and got the correct formula of the volume of the ball.
