说起圆周率,你们一定会想到南北朝时期杰出的数学家、天文学家祖冲之。但你们也许会问,提到祖冲之,说说他的数学家身份也就罢了,还提起天文学家这个头衔干啥?你们这样问就对了,因为祖冲之研究圆周率与此紧密相关——他正是为了研究天文才深入计算圆周率的。天文学真的很重要。在漫长的古代,从有文字记载开始就一直在研究天文,其中最 Speaking of pi, you will certainly think of Southern and Northern Dynasties distinguished mathematician, astronomer Zu Chongzhi. But you may ask, referring to Zu Chongzhi, talking about his mathematician status, mentioning the astronomer’s title? What’s your question? Because Zu Chong’s research on pi is closely related to this In order to study astronomy in-depth calculation of pi. Astronomy is really important. In the long ancient times, astronomy has been studied since the beginning of written records, most of them
