Around the fifth century AD the mathematician, astronomer and calender scholar of ancient China, Zu Chongzhi used a commentary and results from the third century genius Liu Hui, to derive the correct formula for the volume of a sphere, using the principle of Cavalieri (known in China, centuries before Cavalieri bas born). His derivation was totally rigorous and correct.It showed the power and level oflogical deduction andmastery of complex mathematics achieved in early Chinese culture.
