I don't see where the idea of saris from Greek dress comes from either. Greeks generally wore chitons, and women I think wore dresses. Togas in Rome were a male thing and I highly doubt patriarchal India is going to take so kindly to women adopting mens' dress.
Is there any weight to the idea the Pythagoras including his theorem was influenced by India? Or is this just another Hindutva nonsense theory?
I imagine Indians would have learned something about military strategy from the Greeks considering that the first one to stumble upon the place was just the greatest general alive at the time ...
There is no weight to the idea that Pythagoras's theorem was influenced by India.
However, there is also no weight to the idea that Pythagoras's theorem was invented by Pythagoras.
that is clearly not the case- Pythagoras was the first Greek to use that theorem and he left behind the proof for it.
However, the concept itself is mentioned ( squaring the sides of a triangle being equal to the square of the hypotenuse) in babylonian works, in indian works as well as ample material evidence of it being used.
Those two were likely, independent developments as basic math does not need to be a brilliant one-of-a-kind unique invention that cannot occur independently, multiple times, especially when we are talking about basic geometry, which is the simplest of all math.
