Untitled[edit]

I wonder if Zu Chongzhi was really first living person to determing the value becuace Aryabhatta [inventer of zero] is who lived around the same time also was credited with the same feet.


"being rumored to have successfully carried out the division of pi by zero, though most modern mathematicians are skeptical." From where does such a rumour arise? Clark Kent 13:08, 11 March 2006 (UTC)

Well given that it's such a stupid rumor without a source, and not an achievement by any means, I'm deleting it. Clark Kent 07:01, 8 April 2006 (UTC)

Contradiction: Who discovered Cavalieri's principle?[edit]

The article credits Zu Chongzhi with discovering Cavalieri's principle. Yet the article Liu Hui credits the latter with using Cavalieri's principle to find the volume of a cylinder, about two centuries earlier. Both claims apparently are derived from Needham Vol. 3. Can someone who has access to the book clarify this?  --Lambiam 08:48, 28 November 2007 (UTC)

Even worse, Zu Gengzhi (Zu Chongzhi's son) also purportedly discovered Cavalieri's principle! Top.Squark (talk) 19:47, 9 July 2010 (UTC)
Lui Hui started the research on "mu he fang gai" (ie, Cavalieri principle), but did not followed thru. It was completed by

Zu Gengzhi. Zu Chongzhi did not worked on this topic. See Jan claude Martzloff, A history of chinese mathematics p 290-292 --Gisling (talk) 07:11, 23 July 2010 (UTC).

Thx for pointing it out. I updated the articles Liu Hui and Zu Gengzhi accordingly, but it would be nice if you add there the citation. Top.Squark (talk) 12:40, 23 July 2010 (UTC)
