let's take a look at the three world's best created by Zu Chongzhi in mathematics
The first accurate figure of the node month was found
In the northern and Southern Dynasties, Zu Chongzhi created the calendar Daming calendar, which was written in 462 A.D. it was the first time in China to calculate the number of days commonly known as "nodal month" in the calendar, which is very close to the modern value. According to Daming calendar, the length of the year of regression is 365.2428 days, which is the most realistic data before the Tongtian calendar (A.D.) of the Song Dynasty. The first to calculate the precise pi
The first scientist in the world to calculate the precise PI was in the northern and Southern Dynasties
