他并不是严格意义上的数学家。迷信于数字多于证明定理。
The theorem was known by those before him, so he wasn't the originator —
this makes it less likely that he was the one that thought it up or proved
it.
Babylonians knew this equation centuries earlier, and there is no evidence
that Pythagoras either discovered or proved it.[1]
Beyond that, the historical record suggests he was more interested in the
numbers that underlie everyday life than he was in rigorous mathematical
proofs, making it even less likely.
It is doubtful whether Pythagoras (c. 570-495BC) was really a mathematician
as we understand the word. In fact, although genuine mathematical
investigations were undertaken by later Pythagoreans, the evidence suggests
that Pythagoras was a mystic who believed that numbers underlie everything.
He worked out, for instance, that perfect musical intervals could be
expressed by simple ratios.[1] | f***y
