Musical notation in Sumer
Mention of Sumer musical notation deleted. Footnote lead nowhere practically, other related wikipedia pages, namely, Sumer, Music of Mesopotamia and Musical notation, avoid the subject, and no cross-references are found. There is no source confirming that any Sumer findings were actually written music. The only surviving evidence of musical culture known as of today is texts about music, remains of instruments and images of musical events. The misconception seems to be common, you read such stories every now and then, but evidence is still lacking, and this is wikipedia. Anapazapa (talk) 02:12, 29 July 2023 (UTC)

VR/XR Headsets
Someone added Apple Vision Pro to the list. I reverted that edit because it was not sourced, the historic significance of the Vision Pro has not yet been established, and Vision Pro was neither "the world’s first mixed reality headset" nor "the first headset controlled by human eyes" Alpyne (talk) 06:55, 24 February 2024 (UTC)

Twitch
Besides Twitch not being the first 'live streaming service' (that was Camarades in 1998, closely followed by Spotlife) I don't think such almost commercial advertising and history rewriting has a place on Wikipedia. The same goes for the mentions of various other brands.

Potassium nitrate military use in the Seleucid Empire
The cited source for this claim doesn't appear to actually support this statement. The book mentions that the Arabs had a word for potassium nitrate, and that there was evidence of military use in ancient India, but doesn't mention the Seleucid Empire anywhere in the book (as far as I can tell)

I don't know if the claim is true or not but for what it's worth I can't find any other evidence online to support it. I believe it should be marked 'Verify source' 32.221.25.105 (talk) 05:56, 17 July 2024 (UTC)
