One of the very few people in history known almost exclusively by his first name.

Galileo (15 February 1564 - 8 January 1642) worked out (correctly) that the distance an object travels when falling is proportional to the square of the time. He performed a series of elegant experiments with balls rolling down a slope, and timing how long it takes.

* Pendulum is isochronous
* /d/ proportional to EQN:t^2
* Very early telescope
* 1610: Eclipses of Galilean Moons, Moons of Jupiter
* 1610: Phases of Venus
