Pythagoras was specifically known for accumulating the wisdom of diverse cultures—supposedly he met Thales, was initiated as Egyptian priest in Hermopolis, spent time in Babylon after being captured, and was initiated into every mystery cult he could. And as a boy on his home island of Samos, he would have been exposed to the building of the largest stone temple in Ancient Greece (to Hera) and the incredible engineer…
Oh how can you skip the most fun tale of them all. [1] Its authenticity is dubious, but there's probably at least parts of truth in it. In a nutshell, Pythagoras started a cult based around numbers, and the pseudo-divine purity of rational numbers - of which everything can be represented. Hippasus, a member of said cult, however managed to compellingly demonstrate that the square root of 2 could not be a rational num…

That seems irrational…

#44It needs to be renamed as the Tablet Theorem.

#45Confusing calculation with proof is an inexcusable mistake for any serious journal.
There can be little doubt that proving theorems is a cognitive tool that developed on the basis of observed regularities. But both asking the question why and, importantly, answering it using logic are highly non-trivial developmemts.

#46> The Pythagorean Theorem is arguably the most famous statement in mathematics, and the fourth most beautiful equation. Just out of curiosity, which equations are considered the top three “most beautiful?”
I know the top one is generally considered to be Euler's Equation. e^(i * pi) + 1 = 0 It's considered incredibly elegant because it manages to combine multiple fundamental mathematical concepts into a single equation. 1 is the multiplicative identity, 0 is the additive identity, pi is the circle constant, e is euler's number, i is the square root of -1, the basic building block of complex numbers.
e^(i * tau) = 1
You lose the 0, but isn’t it a bit odd the 0 is there in the first place? Normally we’d reduce it to:
e^(i * pi) = -1
Which obviously isn’t as nice in this case.
And hey, if we’re allowed to break the conventions, you can have the 0 back easily.
e^(i * tau) = 1 + 0

#47People will most probably learn that either Bill Gates or Elon Musk invented it all in one evening when an apple fell from a tree.

#48Every group who ever managed to build a building with a rectangular foundation figured out the relation between the side lengths and the diagonal. The Egyptians used Pythagorean triples to measure right angles way before the birth of Pythagoras. But that's not a theorem, just an observation. It becomes a theorem when you prove (i.e. explain why) this relationship always holds, based on more evident things. The Babylo…

It should be noted that such claims were made about many ancient sages to boost their "wisdom pedigree". Plato is said by ancient sources to have traveled to Egypt and Italy, but my understanding is that most modern scholars doubt that those journeys really happened.
