Galileo = Italian scientist who used the telescope to show that the Earth moves around the Sun
Building on the work of predecessors such as Galileo, Copernicus, and Kepler, he laid out the principles of his laws of motion, the universal theories that tied the work of these great minds together.†

Definitions:

(1) (Galileo as in: Galileo Galilei)
Italian scientist who used the telescope to study the heavens and helped show that the Earth moves around the Sun (1564-1642)

Galileo improved the telescope and used it to discover mountains on the Moon, moons orbiting Jupiter, and many stars too faint to see with the naked eye. In physics, he showed that objects of different weights fall at the same rate (ignoring air resistance) and studied motion on ramps and inclined planes. His support for the Copernican idea that Earth goes around the Sun brought him into conflict with Church authorities, and he was tried by the Inquisition and forced to recant, spending his later years under house arrest.
