Whilst studying an old stone tablet containing a mathematics lesson for some Iraqi children around 1500BC, Ernst Weidner alerted the world of mathematics to the possibility that the Pythagorean Theorem was well known a millennium before Pythagoras.
Unfortunately, when he was studying the tablet in 1916, part of it was missing. It wasn’t discovered until the 1980s. At that time, Christopher Walker was looking through the vast supply of stone fragments in the British Museum.
Quite by chance, he discovered the piece of stone which was missing from Weidner’s mathematics lesson. On it was direct evidence that the Pythagorean Theorem was known to the people of Iraq around 1500BC! But it took 3,500 years to declare it to the world!
