Galileo Galilei

Galileo was an Italian mathematician, astronomer, and physicist. He was born in Pisa, Italy on February 15, 1564. In the mid 1570’s, he and his loved ones moved to Florence and he began his formal education in a regional monastery. He was sent to the University of Pisa in 1581. While there, he studied medicine and the philosophy of Aristotle until 1585. Throughout these years at the university, he realized that he never definitely had any interest in medicine but that he had a talent for math. It was in 1585 that he convinced his father to let him leave the university and come home to Florence. Back in Florence, he spent his time as a tutor and started to doubt the Aristotle’s philosophy.

In 1589, he was made professor of mathematics at the University of Pisa where he attended college. His position also necessary him to teach astronomy primarily based on Ptolemy’s theory that all planets and the sun revolved about the earth. In 1592, he left the University of Pisa and went to the University of Padua to turn out to be professor of mathematics. For the duration of his time there, he constructed a clumsy thermometer which would have function if he had taken into consideration atmospheric stress but it nonetheless has a significance in history as becoming a single of the 1st measuring instruments in science. He taught he for 18 years and throughout that time, became convinced that there was truth in the theory of Nicolaus Copernicus a Polish astronomer who believed that all planets which includes earth revolved around the sun.

Whilst nevertheless at Padua, in 1609, he constructed the initially astronomical telescope. When he made use of it to appear at the sky, he easily discovered that most of Aristotle’s and Ptolemy’s theories had been incorrect. His most crucial discovery was when he found the 4 moons of Jupiter in 1610. Later that year Cosimo de Medici, Grand Duke of Tuscany, named Galileo his private mathematician. This brought him back to Florence once once again here he continued his studies in astronomy. Galileo also studied motion, specifically that of freely falling objects. Even though watching swinging lamps in church a single day, he noticed that it requires the similar time among swings no matter how massive or small the arc is. This observation led to his invention of the pendulum clock. He also discovered, prior to Newton, that two objects of diverse weights fell at the same speed. For instance,…
