User:Infrogmation changed the reference to the independent Mayan innovation of zero from Mayan civilization to Maya numerals, I suppose on the theory that the latter is a more specific reference -- except that zero is only mentioned under Maya numerals as a digit, whereas it is made clear in the "Mathematics" section of Mayan civilization that they knew zero as a number in its own right.

Also, the change makes the parenthetical clause read "...outside the Maya numerals mathematical tradition" which is awkward.

It might be good to discuss Mayan mathematics more thoroughly under Maya numerals or perhaps give Maya mathematics its own article. Until then, though, I think it would be best to change the link back.

[edit] You know...

"Brahmagupta discovered the most important concept in all of mathematics, the zero." This is biased. I don't know who was crushing on Brahmagupta when that person wrote this section of the article, but clearly someone was, since this is not anything resembling common knowledge, nor is it cited (but of course, who could be legitimately cited in such a clear cut case of bullshit). This must be unbiased, and rewritten more fluidly.

I agree. The concept was probably in use for several centuries before he used it extensively in his works. deeptrivia (talk) 16:58, 15 October 2006 (UTC)

[edit] Contradiction?

There seems to be a contradiction between this article and the article on the History of gravitational theory:

"Brahmagupta also followed the heliocentric solar system of gravitation, earlier developed by Aryabhata in 499, and hence he understood there was a force of attraction between the Sun and the Earth."

...is surely incompatible with the notion that Brahmagupta assumed the Earth was stationary?

[edit] pronounciation

the pronunciation is fucking horrible —The preceding unsigned comment was added by 70.50.31.14 (talk) 07:26, 1 March 2007 (UTC).

[edit] Father of arithmetic etc.

Four fundamental operations as done today first appeared in Brahmagupta's work. The book was translated by Henry Thomas Colebrooke. Modus Indorum or the method of the Indians has become our arithmetic today. Western scholars has given credit to Greeks for inventing arithmetic which is a scam. —Preceding unsigned comment added by 12.1.48.108 (talk) 16:10, 8 February 2008 (UTC)

I removed the following sentences:

"In mathematics, Brahmagupta is considered the father of arithmetic, algebra, and numerical analysis. The modern arithmetic used today spread from India to Arabia and then to Europe. Initially, it was known as Al Hind in Arabic and De Numero Indorum in Latin. De Numero Indorum means "method of the Indians" and has become our arithmetic and algebra replacing the earlier Roman numerals and abacus-based methods."

Brahmagupta is not generally considered the father of arithmetic, algebra, and numerical analysis. Whether modern arithmetic originates from India depends on what you mean by modern arithmetic; the sentence "Addition, subtraction, division and other fundamental operations using Hindu Arabic numerals first appear in Brahmasputha Siddhanta" which appears later in the article is more specific and thus preferable. "De Numero Indorum" does not mean "method of the Indians" but something like "on the number of the Indians". -- Jitse Niesen (talk) 07:47, 9 September 2007 (UTC)
