Galileo Galilei

Galileo agreed with Copernicus that the planet’s revolved around the sun, but was later forced to renounce his view. Galileo rejected the Aristotelian views of that day. The best example is Aristotle’s idea that heavy objects fall faster than lighter objects. Galileo repeated experiments to see if this was true. He would roll balls of different weights down a hill (and legend has it, dropping them from the Leaning Tower of Pisa) He found out that if an object was the same shape as the other it would drop at the same speed and hit the ground at the same time. He has also been credited with inventing the telescope, this is not true he only developed one from hearing a description of another one.
