Galileo Galilei and His Successors

Galileo Galilei was born in Pisa into a family of minor nobility. His father, Vincenzio, gave lessons in music (and studied its mathematical theory) and helped his wife’s family in their small business. He wished for his son a better than their modest (if not poor) standard of living. However, rather than choosing a career in business as recommended by his father, the 17-year-old Galileo entered the University of Pisa, intending to study medicine. Instead, he became a mathematician and, especially, the founder of experimental physics who also started observation of the celestial bodies using telescopes.
