数学家祖冲之
祖冲之 ( 429-500 年 ) 南朝宋齐时期人 。 他年轻时就学问渊博 , 喜爱数学 , 也喜欢研究天文历法 。
祖冲之最大的成就还是在数学方面 , 他求出了比较精确的圆周率。圆周率是圆的周长和直径之间的比例 , 中国古代很早就知道这个概念 , 但不太准确。祖冲之总结前人经验 , 决定利用三国时候刘徽的 “ 割圆术 ” 来求圆周率 。 可是 , 那时运算的工具是竹棍 , 对于 9 位数的运算 , 要经过 130 次以上的反复计算 , 而且又容易出错 。 祖冲之每算一次 , 至少重复两遍 , 直到几次的结果完全相同才行 。 经过刻苦运算 , 终于得出圆周率大于3.1415926 , 小于 3.1 415927 的结论 。
祖冲之是世界上第一个把圆周率的准确数值 算到小数点后 7 位数字的科学家 , 直到 15 世纪的阿拉伯 数学家阿尔卡西（Al－Kashi）和 16 世纪法国数学家韦达（Viete ）才推算到小数点后16位 , 超过了他 。 除此之外 , 祖冲之编写过一部 《 缀 ( Zhui）术 》 , 收集了他研究数学的主要著作 。 唐朝时把 《 缀术 》列为数学课的主要教科书。

The mathematician Zu ChongzhiZu Chongzhi (429-500) of song in the Southern Dynasties period. When he was young, his knowledge, loves math, who likes to study astronomy. Zu Chongzhi's biggest achievement was in mathematics, he obtained a more accurate ratio. PI is the ratio between the circumference and diameter of a circle, has long been known in ancient China the concept, but not quite accurate. Zu Chongzhi, summarizing the experience, decided to take advantage of the three Kingdoms period of Liu Hui's "cutting circle" came to PI. However, when computing tool is bamboo sticks, for 9-digit calculations, takes more than 130 times for repeated calculations, and prone to error. Zu Chongzhi, each counted once, repeated at least twice, until the times are identical to rows. Through some hard calculations, came to PI than 3.1415926, conclusion less than 3.1 415927.Zu Chongzhi, is the world's first numerical PI accurate to 7 decimal digits of scientists until the 15th century Arab mathematician aerkaxi (Al-Kashi) and in 16th century France mathematician vieta (Viete) projections to 16 decimal digits, overtook him. In addition, Zu Chongzhi to prepare one of the suffix (Zhui) art collection which he works on mathematics major. During math class, the suffix as the main textbook.

Mathematician Zu
Zu (429-500 years) during the Southern Song Qi people. He was young profound erudition, like mathematics, also like to study astronomical calendar.
Zu greatest achievement was in mathematics, he obtained a more accurate pi. Pi is the ratio of a circle's circumference and diameter between the ancient Chinese have long known that this concept, but not quite accurate. Zu summarize previous experience, decided to use three time Liu Hui's "cutting circle method" to find pi. However, when the operation of the tool is bamboo sticks, for 9-digit arithmetic to calculate more than 130 times after repeated, but also prone to error. Zu once every count, repeated at least twice, several times until the result is exactly the same job. After painstaking operation, and finally come to the circumference of greater than 3.1415926, less than 3.1 415,927 conclusions.
Zu is the world's first to accurately calculate the value of pi to seven decimal digits scientists, until the 15th century Arab mathematician Al Casey (Al-Kashi) and 16th-century French mathematician Vedic (Viete) was calculated to one decimal 16, overtook him. In addition, Zu has written an "augmented (Zhui) technique", a collection of major works he studied mathematics. Tang Dynasty when the "Zhuishu" as the main textbook math class.

The mathematician Zu Chongzhi Zu Chongzhi (429-500) the Southern Song Qi period. When he was young he had profound knowledge, like mathematics, also like to study astronomy.
Zu Chongzhi greatest achievement or in mathematics, he obtained more precise pi. PI is between the circumference of a circle and diameter ratio, China ancient early knows this concept, but not very accurate. Zu Chongzhi summed up the previous experience, decided to use the time of Liu Hui's "cyclotomic technique" for pi. However, when the operation tool is a bamboo stick, for the 9 digit arithmetic, to go through repeated calculation more than 130 times,But also prone to error. Zu Chongzhi per time, repeated at least two times, until several of the same caixing. Through hard operation, finally draw Pi is greater than 3.1415926, less than 3.1415927 of the conclusion.
Zu is the world first is accurate value of pi to 7 decimal digits of the scientists, until the fifteenth Century Arabia mathematician Al Casey (Al Kashi) and the sixteenth Century French mathematician Vieta (Viete) was calculated to 16 decimal places, over him. In addition, Zu Chongzhi prepared a "suffix (Zhui) operation",A collection of major works he studied mathematics. The Tang Dynasty took "zhuishu" listed as the main textbook mathematics class.
