What did Zu Chongzhi invent?
Zu Chongzhi is the first scientist in the world to calculate the value of pi to the seventh decimal place.
He invented the water hammer mill (processing grain with water); Copper-driven compass car; A boat that can walk a hundred miles a day; A "propeller" is a timer that uses water, etc.
Zu Chongzhi 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 first calculated the "pi" to the seventh place after the decimal point, that is, between 3. 14 15926 and 3. 14 15927. His "ancestral rate" has made great contributions to mathematical research. It was not until the 6th century A.D./KLOC-that the Arab mathematician Al Cassie broke this record.
What's the impact of what Zu Chongzhi invented?
He was the first person in the world to calculate pi to the seventh place after the decimal point, about 1000 years earlier than Europeans.
Zu Chongzhi calculated the value of pi to six decimal places for the first time in the history of mathematics in the world, that is, between 3. 14 15926 and 3. 14 15927. He put forward the agreement rate of 22/7 and the secret rate of 355/ 1 13, which were the earliest in the world, more than 1000 years earlier than in Europe, so some people advocated calling them "the ancestor of pi".
Zu Chongzhi's character introduction
Zu Chongzhi (429-500) was born in Wen Yuan. Jiankang (now Nanjing) was an outstanding mathematician and astronomer in the Southern and Northern Dynasties.

The Daming Calendar written by him was the most scientific and progressive calendar at that time, which provided a correct method for future astronomical research. His main works are In the Frontier, Composition, Explaining Words, Li Yi and so on.
