Galileo Galilei

Galileo's parents were Vicenzo Galilei and Gulia Vincenzo. Galileo was born on February 15, 1564 in Pisa, which is now Italy. In 1572 when Galileo was eight his family returned to Florence while he stayed in Pisa to live with Muzio for 2 years. At the age of ten he left to join his family. There he was tortured by Jacapo Borghinti. Once he was old enough he was sent to the Camoldelese Montary at vollombrosa. He became a novice later, his father wasn't pleased, and father had decided he would be medical doctor. He returned back home giving up the idea, but continued his schooling. In 1581 he was sent back to Muzio by father to attend University of Pisa to enroll for medical degree. In 1582-83 Ostillo Ricci, a mathematician of the Tuscan Court and a formal pupil of Tartagua, taught a course on Euclid's Elements at the University of Pisa which Galileo attended? In 1585 he quit the coarse and began teaching mathematics, but first privately. In 1586 he started teaching at Vallombrosa and also wrote his first scientific book "The Little Balance" which described Archimedes method of finding in the specific gravities. In 1591 Galileo father die, and since Galileo was the eldest boy he had to provide financial support for his family. He moved to work at University of Padua which paid 3 times his old job. At Padua his duties were to teach Euclid's geometry and standard astronomy to medical students. At Padua Galileo began a relationship with Maria Gamba. In 1600 that had 2 girls Virginia and Livia, then they had a son in 1606 named Vincenzo. Before Galileo had an error in the theory of motion as he set out in De Mote around 1590. In 1609 Paolo Sarpi wrote him telling him about a spyglass. From these reports Galileo began to make a series of a telescope whose performance was better that the Dutch instrument. His first telescope was made from available lenses. By August 1609 he had an instrument with a magnification of about 8 or 9. By the end of 1609 Galileo had turned his telescope on the night sky and began to make a remarkable discoveries. Galileo claimed to see mountains on the moon, and to have proved the Milky Way was made of tiny stars. On June 1610 he became Chief Mathematician at the University of Pisa. He then began to make observations with his telescopes. In 1612 he made series of observations and was able to give accurate periods,
