The telescope was invented on the basis of a “telescope” created by a Flemish lens grinder. Galileo was a man of many professions; philosophy, astronomy and mathematics were among his favourites. Before dedicating himself to the study of the sky, Galileo taught mathematics in Pisa and then in Padua. After creating his telescope he became known as a hero to many people throughout Italy and much of Europe. Galileo Galilei was born in Pisa, Italy, in February 1564. As a teenager he moved to a monastery school, then went on to university. of Pisa where he studied medicine. He always had such a love for mathematics and philosophy that he taught the two subjects in Pisa and then in Padua. Galileo also studied motion, which he used for most of the rest of his career. His contributions ranged from motion science, astronomy, strength of materials, and, of course, the scientific method. His creation of inertia and the law of falling bodies initiated changes in the study of motion. The telescope opened so many doors for Galileo and with that equipment his discoveries were limitless. In 1609 his astronomical discoveries and observations began. Galileo is best known for his discoveries which he transformed into a book, Il Messaggero Stellato. In this book he describes his discoveries about the lunar landscape, the light coming from the Milky Way, Jupiter and its moons, sunspots and the phases of Venus. From a young age, Galileo was annoyed and motivated by the lack of scientific rules. and emphasis on church government. Galileo's approach to learning was truly admirable. Instead of sticking to his course of study, he learned by investigating his daily activities. Learning to investigate further what interested him, he did and... half of the paper... scholars had tried to explain the movement; now their job was to explain the changes in the movement.” In conclusion, Galileo's discoveries are still considered today. In 1640 no other astronomer could look beyond Galileo's discoveries. Galileo's work along with Copernicus and Kepler could not be resolved, until Sir Isaac Newton, the "greatest genius of the scientific revolution", came along and made his series of new discoveries.
