It had been assumed that rudimentary calculus was developed in Europe in the 14th century but now it turns out that the Babylonians worked it out more than 2000 years ago.
Researchers have deciphered a detail on a cuneiform tablet held at the British museum and revealed that it describes the movement of Jupiter.
Babylonians believed that Jupiter's position was integral to predicting the weather, the price of goods, and the fluctuating river levels throughout the year.
"The now-decoded 'text A' describes a procedure for calculating Jupiter’s displacement across the ecliptic plane.. by tracking Jupiter’s speed as a function of time and determining the area under a time-velocity curve."
