'''Ch'in Chiu-Shao (秦九韶, sometimes transcribed Qin Jiushao''') (ca. 1202-1261) was a China mathematician, now regarded as one of the greatest mathematicians of the 13th century. This is particularly remarkable, as Ch'in did not devote his life to mathematics. He was accomplished in many other fields, however, and held a series of bureaucratic positions in several Chinese provinces. Ch'in Chiu-Shao's reputation as a mathematician lies in the ''Shu-shu chiu-chang'' (Mathematical Treatise in Nine Sections), issued in 1247. The treatise covered matters that ranged from indeterminate analysis to military matters and surveying. In the treatise, Ch'in included a version of the Chinese remainder theorem, which used algorithms to solve problems. Ch'in recorded the earliest explanation of how Chinese calendar experts calculated astronomy data according to the timing of the winter solstice. Among his accomplishments are introducing techniques for solving equations, finding sums of arithmetic series, and solving linear systems. He also introduced the use of the 0 (number) in Chinese mathematics. ==External links== * [http://www-gap.dcs.st-and.ac.uk/~history/Mathematicians/Qin_Jiushao.html MacTutor biography for "Qin Jiushao"] *[http://www.math.sfu.ca/histmath/China/13thCenturyAD/Qin.html Simon Fraser University biography for "Qin Jiushao"] 13th century mathematicians Chinese mathematicians Number theorists
Shouldn't his name in Chinese symbols be 秦就少, rather than 秦九韶? _JarlaxleArtemis">User:JarlaxleArtemis 20:04, Apr 17, 2005 (UTC)
