Mayan[edit]

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.

Gravity[edit]

In 628 CE, Brahmagupta first described gravity as an attractive force, and used the term "gurutvākarṣaṇam (गुरुत्वाकर्षणम्)" in Sanskrit to describe it.

This sentence is there in the top itself. But cannot find the original verse in which the word gurutvākarṣaṇam is mentioned. none of the source cited mentions saṃskṛta verse. Among the sources, earliest available one is Al Beruni, who lived nearly half a millennium after Brahmgupta. Al Beruni's work are mostly in translation. He also doesn't quote the exact word. So where exactly is the word gurutvākarṣaṇam in Brahmagupta's works?. ChandlerMinh (talk) 11:39, 21 May 2023 (UTC)[reply]
