Science Friday: Babylonians developed trigonometry ‘superior’ to modern day version 3,700 years ago | How Orange Peels Revived A Costa Rican Forest August 23, 2017

 

They also beat the Ancient Greeks to it, according to Australian academics

The Ancient Babylonians knew about a form of trigonometry more advanced than the modern-day version – about 1,000 years before its supposed invention by the Ancient Greeks, academics in Australia say.

Known as Plimpton 322, it is already known to contain evidence that the Babylonians knew Pythagoras’ famous equation for right-angled triangles, long before the Greek philosopher gave his name to it.

A team led by Princeton University researchers surveyed the land 16 years after the orange peels were deposited.
