Galileo Galilei (1564‐1642)
Galileo Galilei was born on 15 February 1564 in Pisa and was educated at the Camaldolese Monastery at Vallombrosa. In 1581 was sent by his father to enrol for a medical degree at the University of Pisa. Galileo never seems to have taken medical studies seriously, attending courses on his real interests which were in mathematics and natural philosophy. He left Pisa in 1585 without completing his medical degree and began teaching mathematics in Florence and later at Siena. During the summer of 1586 he taught at Vallombrosa, and in this year he wrote his first scientific book The little balance (La Balancitta) which described Archimedes' method of finding the specific gravities of substances using a balance. His reputation grew and in 1588 he received a prestigious invitation to lecture on the dimensions and location of hell in Dante's Inferno at the Academy in Florence. In 1589, Galileo was appointed to the Chair of Mathematics at the University of Pisa where he wrote De Motu a series of essays on the theory of motion which he never formally published. The book contains his important idea that one can test theories by conducting experiments and gave the famous example of testing falling bodies using an inclined plane to slow down the rate of d

Galileo's experiments into gravity refuted Aristotle ©Galileo was a hugely influential Italian astronomer, physicist and philosopher.
Galileo Galilei was born on 15 February 1564 near Pisa, the son of a musician. He began to study medicine at the University of Pisa but changed to philosophy and mathematics. In 1589, he became professor of mathematics at Pisa. In 1592, he moved to become mathematics professor at the University of Padua, a position he held until 1610. During this time he worked on a variety of experiments, including the speed at which different objects fall, mechanics and pendulums.
In 1609, Galileo heard about the invention of the telescope in Holland. Without having seen an example, he constructed a superior version and made many astronomical discoveries. These included mountains and valleys on the surface of the moon, sunspots, the four largest moons of the planet Jupiter and the phases of the planet Venus. His work on astronomy made him famous and he was appointed court mathematician in Florence.
In 1614, Galileo was accused of heresy for his support of the Copernican theory that the sun was at the centre of the solar system. This was revolutionary at a time when most people believed the Earth was in this central posi
