Nearly 3,000 years ago, ancient Babylonians began one of the longestrunning science experiments in history. The goal: to predict eclipses. This singular aim has driven innovation across the history of science and mathematics, from the Saros cycle to Greek geometry to Newton’s calculus to the threebody problem. Today, eclipse prediction is a precise science; NASA scientists predict eclipses hundreds of years into the future. (Featuring Stephen Wolfram.)
