Not a Mandean?[edit]

http://www.scribd.com/doc/18089576/Biographies-of-Muslim-Scholars-and-Scientists p. 22 seems to claim that Thabit was not a Mandean, but a Sabian. Other sources say he was a Sabian. So does his name. What is the correct action here? Replace Mandean with Sabian?

Also, is there some justification for featuring physician above astronomer, translator and mathematician?

Philip K. Hitti claims he was a 'pseudo-Sabian', one of the followers of some Babylonian star-worshipping cult who claimed (or converted) to be Sabians to benefit as people of the Book and so escape persecution. Hitti's sources seem weighty, so perhaps a change is in order here and in the articles on Thabit's offspring? I am not an expert on the issue myself, so HItti's view may be controversial. —Preceding unsigned comment added by 41.185.167.243 (talk) 09:12, 23 June 2010 (UTC)

Generalization of the Pythagorean theorem?[edit]

This looks garbled to me:

Another important contribution Thabit made to geometry was his generalization of the Pythagorean theorem, which he extended from special right triangles to all triangles in general, along with a general proof.<ref>Aydin Sayili (1960). "Thabit ibn Qurra's Generalization of the Pythagorean Theorem", Isis 51 (1), p. 35-37.</ref>

so I've moved it here for comment William M. Connolley (talk) 00:09, 19 March 2011 (UTC)

His birthdate[edit]

In the arabic version of this article, it is said that he is born in 836 ad, not 826 ad. Where is the truth ? — Preceding unsigned comment added by 78.223.12.118 (talk) 22:29, 1 January 2012 (UTC)

Sâbit ibn Kurrâ[edit]

in Turkish. Böri (talk) 10:18, 21 July 2013 (UTC)

I do this editing because there is a lot more to say about Sabit bin Kurra. Before anything else this page does not contain his most important contributions and inventions to mathematics:

1- He was the first to apply algebra to geometry. Therefore it is accepted that he is the founder of analytical geometry.

2- He was the first to invent Calculus. His work on Calculus was later developed and expanded by Ebul vefa Būzjānī. His work must have influenced directly or indirectly western mathematicians like Galileo, Gamss, Newton, Euler, Faraday, etc.

3- He invented a geometrical method for calculating algebraic equations of third degree.

4- He worked extensively on irrational numbers and provided new postulates about them.

S. B. Boyer, Scientist of History, talks about Sabit bin Kurra in his History of Mathematics "that were it not for his work on mathematics, mathematical knowledge would have remained a secret for centuries."

Here is a list of some of his treatise (listed in the Turkish language):

1- Kitab-ul-amel bil Kurre;

2- Kitabu tercemeti(=translation) ve ihtisar-il-macisti lil-Batlamyus(Ptolemaeus)

3- Kitabu tercemeti cografiyat(=geography) -il-ma'mure li-Arşimed(=Archimides)

4- Kitabu şerh-il-mu'tiyyati Oklidis

5- Kitabun fil-mesail-u-hendesiyyeti(=geomerty)

6- Kitabun fi ibta-il hareketi fil-felek-il-buruc (a book on motion on heavenly bodies and constellation)

7- Kitab-i hisab-il-heyeti

8- Kitab-ul muhtasar fil-hendese

9- Risaletun fi hareket-il-felek (a booklet on motion on heavenly bodies)

10- Kitab-ul medhal alel-mantık

Please footnote "An"[edit]

The phrase "... was an Sabian mathematician, ..." is not necessarily in error for using "an" instead of "a". There may be a peculiarity of pronunciation and orthography pertaining to "Sabian" such that it is pronounced beginning with something that would be transcribed in phonics as a kind of vowel. But then I think a footnote is required after "an" to document this, rather than leave it be perceived as a mistake, tempting some to CHANGE it to what would then be a mistake, i.e. "a". Yet another reason why WikiP needs to be copy-edited by persons whose expertise is in the standards of writing your articles, NOT in the subject-matter of the articles.2604:2000:C682:B600:9CEE:84D6:D6E:F0C4 (talk) 22:45, 7 July 2016 (UTC)Christopher L.
