Galileo tested [[Aristotle]]'s theory that heavy objects fall faster than light ones and found it was a consequence of air resistance, not [[gravity]]. By making careful measurements he found he could use mathematics to measure the acceleration of gravity and predict the movements of [[pendulum]]s and tides.
