How did Newton figure out gravity? On the shoulders of giants | Science4All 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.

Newton’s thoughts are so clear that they had to be true. And for centuries, they were to convince any scholar who would ponder them! Until came some unknown patent clerk…
