Zu Chongzhi (祖冲之, pinyin Zǔ Chōngzhī, Wade-Giles Tsu Ch'ung-chih) (429-500) was a Chinese mathematician and astronomer during the Liu Song and Southern Qi Dynasties (of the Southern Dynasties). His ancestors hailed from Qiu district, Fanyang Commandery (part of modern Beijing). To flee from the ravages of war, Zu Chongzhi's grandfather Zu Chang moved from Hebei, in north China, to south of the Yangtze River, as part of the massive population movement during the Eastern Jin Dynasty. Zu Chang at one point held the position of "Minister of Great Works" (Dàjiàngqīn) within the Song Dynasty (420-479) and was in charge of government construction projects. Zu Chongzhi's father also served the court and was greatly respected for his erudition. Zu Chongzhi was born in 429 in Jiankang (today Nanjing). His family had historically been involved in astronomy research, and from childhood Zu Chongzhi was exposed to both astronomy and mathematics. When he was only a youth his talent earned him much repute. When Emperor Xiaowu heard of him, he was sent to an Academy, the "Huálín Xuéshěng", and later at the Imperial Nanking University(Zongmingguan) to perform research. In 461 in Nanxu (today Zhenjiang in Jiangsu) he was engaged in work at the office of the local governor. His achievements included: the Daming calendar (大明) introduced in 465. deriving two approximations of pi, which held as the most accurate approximation for π for over nine hundred years. His best approximation was between 3.1415926 and 3.1415927, with 355?113 (密率, Milü, detailed approximation) and 22?7 (约率, Yuelü, rough approximation) being the other notable approximations. finding the volume of a sphere as being 4πr3/3, where r is radius.

之生於南北朝（西元409-502）范人。 他利用割求得接二四五七六形的周，而推算出周率的值是在3.1415926和3.1415927之。而且他采用22/7作率，355/113作密率。些果都比西方早超世。要知道只有算算工具，算工作是很繁重的。由於他不畏苦，有的毅力才能得光的成果。 祖之了求周率小後的第七位值，把正六形的算到小後二八千六百七十二位，是很了不起的成就。中有三值得我注意的， 他是自己做的，因平方不能你求小後第一位到第八位，同，有另外一人求第九位到第十六位，....... 目前使用的算到了十二世才出，祖之那代有算，可其平方的辛。 祖之不可能使用阿拉伯字，阿拉伯字在十二、十三世才入中，可以想像其之麻。 祖之不是家，是天文家、文家、械明家。在天文方面，他提出了最好的法「大明」，而且算出地球太一周所需的是365.24281481日，和在由器得到的365.2422日，他的字到小後三。他也曾算出月球地球一周27.21223日，和在公的27.21222日，在小第五位才有1的差，一千多年前他成果是值得我傲的。他明了指南、水碓磨千里船等，成功造了似葛孔明的「木牛流」的工具，中到祖之是如何的明。 祖之在世不得意，不但有大官做，而且在生前不到「大明」的用。最令人惋惜的是他和子成果的《》在宋朝失了。今日在月球上很多座以大科家命名的山，祖之是其中一，亦是中的唯一一，由此可到他是如何的大呢！13413D6BADCE0D57
