The Mechanical Universe
The Law of Falling Bodies. With the conventional wisdom of the Aristotelian world view, almost everyone could see that heavy bodies fell faster than lighter ones. Then along came Galileo. His genius deduced that the distance a body has fallen at any given instant is proportional to the square of the time spent falling. From that, speed and acceleration follow with a little help from a mathematical tool called a derivative. (from themechanicaluniverse.org)
