Talk:Fibonacci

Fibonacci or Leonardo Fibonacci or Leonardo da Pisa
While he was alive, the mathematician went by the name Leonardo. Many google searches have his name: Leonardo Fibonacci, therefore, I added that to the very beginning of the article. 73.85.204.254 (talk) 15:53, 16 May 2019 (UTC)
 * Do you have reliable published sources attesting to the use of that form of the name? If not, you should not be adding it to the article. —David Eppstein (talk) 16:25, 16 May 2019 (UTC)

References to Hammadid Empire
The beginning of the Bibliography section of this article states that Fibonacci was born around 1170, and that his father, Guglielmo, directed a trading post in Bugia. Bugia is indicated in this section to be “the capital of the Hammadid empire.” However, the linked wiki article about the Hammadid dynasty states its period of influence being between 1014-1152. So by the time Fibonacci was supposed to have been born, the Hammadid empire had already been conquered. I realize this may be nit-picky, and I suppose one could read that sentence in the Bibliography section as pertaining more to Fibonacci’s *father* than to Fibonacci himself. However, I still think this bit warrants some clarification. If we mention Bugia as being the capital of the Hammadid empire, then I think we should indicate that this predated Fibonacci’s birth. Otherwise, I think the information should be updated to indicate Bugia’s status as it was during Fibonacci’s lifetime. Again, I realize this is super nit-picky, I just don’t like to see inconsistencies between related wiki articles. 73.170.6.73 (talk) 03:05, 10 June 2022 (UTC)

Please change: "Guglielmo directed a trading post in Bugia (Béjaïa), in modern-day Algeria, the capital of the Hammadid empire.[16] Fibonacci travelled with him as a young boy, and it was in Bugia (Algeria) where he was educated that he learned about the Hindu–Arabic numeral system." To "Guglielmo directed a trading post in Almohad Bugia (Béjaïa), in modern-day Algeria.[16] Fibonacci travelled with him as a young boy, and it was in this city that he was educated and learned about the Hindu–Arabic numeral system." Bejaia at that time was Almohad not Hammadid (And the Hammadid kingdom was never an empire).TybenFree (talk) 23:22, 10 January 2024 (UTC)

Title of Liber Abbaci
I'm almost certain that it was spelled with two b's, which would distinguish it from the abacus. This is important because one of the main things the book accomplished was to eliminate need for the abacus, therefore it seems a little misleading to include this translation and not to include the second "b", as was indicated in The Man of Numbers, one of the books in the "further reading" list. 2601:644:9182:E590:9ECB:89BB:807A:8EF2 (talk) 06:09, 8 April 2024 (UTC)
