Talk:Kamāl al-Dīn al-Fārisī

First paragraphs
Can someone combine the first two paragraphs (which together form a single sentence) into one? I attempted to do so, but the multiple switches between left-to-right and right-to-left text confused either me or my browser (or both). Michael Slone (talk) 01:19, 13 February 2006 (UTC)

Why mention the religion of scientists??
In many pages of Arab scientists it is emphasized that they are Muslim.

Is this really necessary? Do we say, for example, that Galileo was a "Christian scientist" ?

The same is repeated in many pages of Arab scientists. I could give a list but it is easy to verify it. — Preceding unsigned comment added by 2601:184:4202:57B0:82FA:5BFF:FE19:E8F9 (talk) 02:51, 4 December 2015 (UTC)

Fundamental theorem of arithmetic
Although some users seem to think Euclid discovered this theorem, it's quite clear that this is wrong. While Euclid took decisive steps, it was Kamal al-Din al-Farisi who stated the theorem for the first time. This source clearly states that the FTA does not appear in the Elements, but two significants propositions are in Euclid's work :  page 208.

This other source states : "The oldest surviving text with a clear statement that every positive integer can be written as a finite product of prime numbers was given by Al-Farisi" page 5.

As to the the statement of in his last edit summary, i'm sorry to say so, but it sounds like JDLI. Rashed's statement is very clear about al-Farisi's work on this theorem : page 385.---Wikaviani (talk) 15:52, 3 May 2018 (UTC)


 * Rashed's statement isn't by any means clear. As I said in my edit summary, a plainer interpretation is that this was the fist time in al-Farisi's writings that the statement appears, not that this was the first time it ever appeared anywhere.  It's an offhand comment in the source for a fairly murky question.  Something better would be needed.  –Deacon Vorbis (carbon &bull; videos) 16:22, 3 May 2018 (UTC)


 * I'm sorry but your statement is original research because you suppose that Rashed means "first time in al-Farisi's work" and not "first time" while he just says "first time" ! I gave you more sources above stating that Euclid did not state this theorem.
 * Since you asked me another source to support my edit, i gave you another source supporting al-Farisi's claim : states : "The oldest surviving text with a clear statement that every positive integer can be written as a finite product of prime numbers was given by Al-Farisi" page 5. Now, i'm going to edit again the article and i hope that you and me agree on this point. Best regards.---Wikaviani (talk) 20:31, 3 May 2018 (UTC)

Year of birth
According to this article al-Fārisī was born at three different times: the opening pargraph says 1267, the fact box says 1265 and the categories say 1260. Which is correct? I notice that Encyclopedia of the History of Arabic Science as well as The Oxford Dictionary of the Middle Ages both support the year 1267, but that other sources (for example encyclopedia.com) say "c. 1260" or leave the year of birth as unclear or unkonown. /FredrikT (talk) 14:27, 8 February 2021 (UTC)
