[wavefunction]

Not to be pedantic but the Pythagorean Theorem was probably "discovered" and at least described much earlier than either Pythogoras or "the Chinese."

Gougo only provided a reasoning for the 3-4-5 triangle but not a general solution for other triangles. The Apastamba Sulba Sutra (~600BCE from "India") contained a numerical proof for the theorem. The Assyrians and Babylonians recorded "Pythagorean triples" but didn't mention triangles.

It's only until Euclid comes along that a proper axiomatic proof is provided. None of takes away from all those that contributed to the upward climb that is human history, though. It's high time to appreciate human achievements rather than "national or ethnic" ones.
