WHAT DID GALILEO DO?
Galileo was famous for inventing the thermometer, perfecting the telescope and for experimenting with gravity and pendulums (which influenced Newton's laws of motion).He also dropped all Aristotelian talk of WHY things moved, and thought more about HOW things move, through painstaking observations and measurements. Galileo also thought of things such as time, distance, and acceleration to describe how things move.
Born in Pisa, Italy approximately 100 years after Copernicus, Galileo became a brilliant student with an amazing genius for invention and observation. He had his own ideas on how motion really worked, as opposed to what Aristotle had taught, and devised a telescope that could enlarge objects up to 20 times. He was able to use this telescope to prove the truth of the Copernican system of heliocentrism. He published his observations which went against the established teaching of the Church. He was brought to trial and, although he made a confession of wrong-doing, he was still imprisoned for life. But it was too late to lock away the knowledge that Galileo shared. Other scientists, including Sir Isaac Newton and Johannes Kepler, seized its importance and were able to learn even more about the ways of the world and the heavens beyond.These early scientists' legacy continues to this day. As time goes on, we use our instruments, science, math, reasoning, and creativity to learn more about the secrets of the Universe. In this way, we are directly linked to the astronomers of centuries ago who gave us direction to discover more about the dances of the planets and the nature of the stars.
