Italian astronomer and scientist Galileo Galilei (1564 - 1642) performs his legendary experiment, dropping a cannonball and a wooden ball from the top of the Leaning Tower of Pisa, circa 1620. This was designed to prove to the Aristotelians that objects of different weights fall at the same speed. (Photo by Hulton Archive/Getty Images)
