Xu Yue


Xu Yue
born с 185, Donglai, China
died с 227, China

Chinese astronomer and mathematician.

He wrote several books, of which only Shushu jiyi ("Memoir on the Methods of Numbering") is extant; some scholars question its authenticity. The treatise was used as an auxiliary mathematics textbook in the Tang (618–907) and Song (960–1279) state universities. Its first part provides three methods of assigning the powers of 10 up to 104,096 to traditionally established terms for "large numbers" and alludes to a method of indefinite generation of even larger numbers. The second part contains descriptions of various devices for representing, if not actually manipulating, large numbers. Among them the book mentions a device resembling the abacus, which some scholars believe originated in China.

▪ Chinese astronomer and mathematician
Wade-Giles  Hsü Yüeh 
born c. 185, Donglai [modern Shandong province], China
died c. 227, China

      Chinese astronomer and mathematician.

      Xu was a disciple of Liu Hong (c. 129–210), an influential government astronomer and mathematician. Apparently, Xu never held any official government position, yet his expertise was highly esteemed by official astronomers who invited his participation in the debates (220–227) concerning the accuracy and merits of Liu's new calendar (the Qianxiang calendar).

      Xu wrote several books, of which only Shushu jiyi (“Memoir on the Methods of Numbering”), with a preface by Zhen Luan (flourished c. 560), is extant; some scholars question its authenticity, claiming that it was a forgery written in its entirety by Zhen. The treatise was used as an auxiliary mathematics textbook in the Tang (Tang dynasty) (618–907) and Song (Song dynasty) (960–1279) state universities. Its first part provides three methods of assigning the powers of 10 up to 104,096 to traditionally established terms for “large numbers” and allusively mentions a method of indefinite generation of even larger numbers, which has led to comparisons with Archimedes' The Sand-Reckoner (3rd century BC). The second part contains descriptions of various devices for representing, if not actually manipulating, large numbers—among them a device resembling the abacus, which some scholars believe originated in China.
