Aryana, History of Iranian Iranic and Persian Civilization

Pythagoras & Persia
How many people are aware that Pythagoras was born in Persian-ruled Ionian Greece (inside the Persian Empire) and then travelled both to the Persian Satrapie of Egypt studying mathematics with the priests, mathematicians, and scholars there, and then to the Capital of the Persian Empire in Babylon, studying with the Iranian Magi for another 12 years?
And how many people know that according to both ancient biographers such as Diogenes Laërtius and modern historians,  such as Christoph Riedweg of Cornell University, Pythagoras learned his philosophy from the Magi in Persia?
