Plimpton 322 is the name given to a 3,800-year-old clay tablet discovered in Iraq in the early 20th Century by archeologist Edgar J Banks, the man believed to have inspired Indiana Jones. Over time this tablet has become one of the most significant and most studied objects of the ancient world.

Dr Daniel Mansfield, of the University of New South Wales, who has studied Plimpton 322 along with other similar tablets, argues that these are evidence that the Babylonians were solving real-world problems, such as surveying, using the basics of Pythagoras' theorem 1,000 years before the ancient Greeks.
