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 family moved to Florence and he started his formal education in a local monastery. He was sent to the University of Pisa in 1581. While there, he studied medicine and the philosophy of Aristotle until 1585. During these years at the university, he realized that he never really 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 began to doubt the Aristotle’s philosophy.

In 1589, he was made professor of mathematics at the University of Pisa where he attended school. His position also required him to teach astronomy based on Ptolemy’s theory that all planets and the sun revolved around the earth. In 1592, he left the University of Pisa and went to the University of Padua to become professor of mathematics. During his time there, he constructed a clumsy thermometer which would have work if he had taken into consideration atmospheric pressure but it still has a significance in history as being one of the first measuring instruments in science. He taught he for 18 years and during that time, became convinced that there was truth in the theory of Nicolaus Copernicus a Polish astronomer who believed that all planets including earth revolved around the sun.

While still at Padua, in 1609, he built the first astronomical telescope. When he used it to look at the sky, he easily found that most of Aristotle’s and Ptolemy’s theories were wrong. His most important discovery was when he discovered the four moons of Jupiter in 1610. Later that year Cosimo de Medici, Grand Duke of Tuscany, named Galileo his personal mathematician. This brought him back to Florence once again here he continued his studies in astronomy. Galileo also studied motion, especially that of freely falling objects. While watching swinging lamps in church one day, he noticed that it takes the same time between swings no matter how big or small the arc is. This observation led to his invention of the pendulum clock. He also discovered, before Newton, that two objects of different weights fell at the same speed.

For six years, Kepler taught, geometry, Virgil, arithmetic, and rhetoric. There he worked out a complex geometric hypothesis to account for distances between the planetary orbits-orbits that he mistakenly assumed were circular. Kepler then proposed that the sun emits a force that diminishes inversely with distance and pushes the planets around in their orbits. Kepler published his account in a thesis entitled Mysterium Cosmographicum (“Cosmographic Mystery”) in 1596. This work is significant because it presented the first comprehensive and logical account of the geometrical advantages of Copernican theory.

Later at University of Padua he was exposed to a new theory, proposed by Nicolaus Copernicus, that the Earth and all the other planets revolved around the sun. Galileo's observations with his new telescope convinced him of the truth of Copernicus's sun-centered or heliocentric theory. In 1610, Galileo published a book, The Starry Messenger, describing his findings that supported the Copernican theory. Galileo's support for the heliocentric theory got him into trouble with the Roman Catholic Church. He was forced to abandon his astronomical pursuits.

When he returned home, he set up two pendulums and swung one with a large sweep and the other with a small sweep and found that they kept time together. To this point, he had been kept away from mathematics, but upon accidentally attending a lecture on geometry, he talked his father into letting him study mathematics and natural philosophy instead. He created a thermoscope which is somewhat like the thermometer and in 1586 published a small book on the design of a hydrostatic balance he had invented. Galileo also studied disegno, which is like fine art, and in 1588 he was instructor in the Accademia delle Arti del Disegno in Florence, teaching perspective and chiaroscuro. With that Galileo acquired an aesthetic mentality.
