Galileo Galilei Astronomy : Everything You Need To Know
By Henry Diaz
Thank you for choosing to read this paper, it was written specifically to be of aid to you.
Galileo was born in Pisa, Italy in the late 1500's. He first became a math teacher even though he had no degree in the subject, and here he began his path to greatness. It was as a math teacher that he first showed students that Aristotle was incorrect in his claim that a heavier object would fall faster than a lighter one. Aristotle was so popular that Galileo soon lost his teaching job, and so sought work in Padua. It was here that his career began.
He began to study Physics and invented a new measuring device, the compass. He developed formula for the path projectiles took, and for falling bodies. These became very important in astronomy, later. However except for an allegiance to the work of Copernicus over Ptolemy and Aristotle, Galileo claimed to be disinterested in astronomy. Copernicus had proposed that the solar system is heliocentric, that is that the planets rotate around the sun. However most people held that Aristotle and Ptolemy were correct in their theory that all the planets, even the sun, orbited the Earth. As time went by Copernicus, and Galileo, were proven correct.
Galileo was the first to look at the night sky through a spyglass, thus using the first telescope. He used it to see features on the moon such as mountains and craters. He also learned that the milky way was made up of individual stars. He went on to discover Jupiter's four largest
moons. He published his findings and became the court mathematician in Florence. No longer having to earn a living teaching, he could spend more time exploring. It took him only 9 months to discover Saturn's phases. It was yet more proof that his trust in Copernicus was well founded.
Galileo's original dispute was with Aristotle's teachings. Galileo found a great deal of support with other modern scientists who wrote of his work. But Aristotle was popular with the church because an Earth centered solar system put man's home, and thus man, at the center of things. In 1614 a priest in Florence denounced Galileo Galilei Astronomy. Galileo retorted that the bible has no bearing on science. In 1616 Galileo was ordered to stop teaching that the Earth revolves around the sun. Galileo complied, continuing his study of falling objects, comets, and methods to determine longitude at sea based on the phases of Jupiter's moons. Galileo signed a document proclaiming his agreement with the Earth centered solar system, one in which the Earth doesn't move. But he had one more thing to say on the subject. "I would say here something that was heard from an ecclesiastic of the most eminent degree; "And yet ... it moves."
