Babylonians may have done trigonometry 1000 years before the Greeks

UNSW/Andrew Kelly

A team of mathematicians studying a famous Babylonian tablet have come to a startling conclusion: the ancient people who created the tablet had an in-depth knowledge of trigonometry, and used a method that is in some ways more accurate than our own. The research was published in the journal Historia Mathematica.

Why it matters: The tablet, which predates Greek trigonometry by about 1000 years, shows a radically different approach to math. "We have to really get outside of our own culture to see from their perspective to be able to understand it," Daniel Mansfield, the paper's lead author, told Science.
