Galileo Galilei was a polymath born on February 15, 1564 in Pisa, Tuscany, a region in Italy, to his parents Vincenzio and Giulia Galileo. He was apart of one of the most powerful families in Florence and lived an expensive lifestyle. He accomplished very much in his early life.
In 1581, Galileo entered the university of Pisa, unfortunately he had to leave four years later due to lack of funds, however, in that time, he accomplished very much. “At age 17, Galileo went to the University of Pisa. He enrolled as a medical student, following his father's advice, but turned to math, after persuading his father that he didn't want to be a doctor. His father allowed him to be tutored by the Tuscan court mathematician, Ricci, who designed fortifications, which no doubt impressed Galileo.” (Life of Galileo. N.p., n.d. Web. 13 May 2017. <http://galileoandeinstein.physics.virginia.edu/lectures/gal_life.htm>. ) Now having a higher education, he realized a pendulum’s constancy of swing time could be used to measure a patient's pulse in hospital. With this knowledge he built a simple device with a built in ruler than read off the patient’s pulse rate.
In 1589, Galileo conducted experiments was falling objects and produced Du Motu (On Motion). His theories on motion were miraculous but, because he became cocky and arrogant, his colleagues shut him out and the University of Pisa did not renew his contract. In 1604 he published The Operations of the Geometrical and Military Compass revealing his practical technological applications. He was able to refine his theories on motion and falling leading him to develop the universal law of acceleration. He went further and even spoke about his Copernican theory that the Earth and all planets revolved around the sun.
At 25 he was appointed to the Chair of Mathematics in Pisa. He had to give two lectures to the Florentine Academy on mathematical topics. Here, he did some of his most famous work, his delineation of hell in Dante’s Inferno. His lecture was superb and he got the job , however, his analysis was seriously flawed. He realized many mistakes he made but, kept quiet because no one else seemed to have noticed. About 3 years later, in 1592, he moved to a better position of Padua.
Galileo Galilei had an astonishing amount of accomplishments in his lifetime which is most likely why he's known as, “The Father of Modern Science.” Even scientists like Albert Einstein looked up to Galileo. People during the Renaissance times did not exactly.. like his work however looking back I’m sure they would be greatly impressed.
