Galileo Galilei (1564-1642)
Galileo was an Italian physicist, mathematician, engineer, astronomer, and philosopher who named the father of science. He was born in Pisa Italy, but later moved to Florence with his family. In 1583, Galileo entered the University of Pisa to study medicine. He soon became fascinated with math and physics. He later published "The Little Balance" describing hydro-static principles of weighing small quantities which allowed him to obtain a teaching position at the University of Pisa.
His investigation of the Laws of Motion and improvements to the telescope helped give us a better understanding of the world around us. He developed heliocentrism, the idea that the Earth revolved around the sun, led to many disputes between the Roman Catholic Church. Once he passed, the church accepted the scientific truths.
