Science4All (english)'s video: How did Newton figure out gravity Relativity 13

The theory of gravity did not fall from trees. It took a giant, standing on the shoulders of other giants. Building upon Descartes' algebraic geometry, Galileo's law of falling objects and Kepler's law of planetary orbits, Newton would mark History, as he would infer the fundamental laws of motion and gravity.
