The telescope was invented based off of a “spyglass” that was created by a Flemish lens grinder. Galileo was a man of many trades; philosophy, astronomy, and mathematics were among his favorites. Before he started studying the skies, Galileo taught math at Pisa and then Padua. After creating his telescope he became known as a hero to many people across Italy and most of Europe.
Galileo Galilei was born in Pisa, Italy in February of 1564. As a teenager his moved to a monastery school, and then continued on at the University of Pisa where he studied medicine. He always had such a love for math and philosophy that he taught the two subjects at Pisa and then Padua. Galileo also studied motion, which he used for the majority of the rest of his career. His contributions ranged from the science of motion, astronomy, strength of materials, and of course the scientific method. His creation of inertia and the law of the falling bodies started the changes to the study of motion. The telescope opened up so many doors for Galileo and with that piece of equipment his discoveries were limitless. In 1609 his astronomical discoveries and observations started. Galileo is most known for his discoveries that he turned into a book, The Starry Messenger. In this book he covers his discoveries of the landscape on the moon, the light coming from the Milky Way, Jupiter and its moons, Sunspots and the phases of Venus.
From a young age Galileo was both bothered and motivated by the lack of scientific rule and emphasis on church rule. Galileo’s approach to learning was very admirable. Instead of sticking to his course of study, he learned by investigating his everyday activities. By learning to inquire further about what interested him, he made extraordinary discoveries, such as his invention of the grandfather clock. As during this time it was difficult to keep time accurately, he hypothesized and experimented which led to his many discoveries.
Galileo revealed himself as a huge advocate of Copernicus’s heliocentric system in The Starry Messenger. The Roman Inquisition of the Catholic Church disapproved of Copernicanism and made Galileo discard the Copernican thesis. Later he was told that he was allowed to continue to discuss Copernicanism as long as he knew that he was not a statistic, but it was a mathematical theory. It has been discussed that the church didn’t like the Copernican system because it endangered the whole beginning of the universe. “The heavens were no longer a spiritual world but a world of matter. Humans were no longer at the center, and God was no longer in a specific place.” The system created such doubts that it seemed right for them just to criticize it.
Through his crafty telescope, he could see more clearly the moon and what it is all about. He found out that the moon had a landscape features similar to the earth, with mountains and valleys. This...
