Galileo Galilei (February 15 1564 – January 8 1642) was an Italian physicist, astronomer, astrologer, and philosopher who is closely associated with the scientific revolution. His achievements include improvements to the telescope, a variety of astronomical observations, the Law of Inertia and Fundamental Law of Dynamics laws of motion, and effective support for Copernicanism. He has been referred to as the "father of modern astronomy", as the "father of modern physics", and as the "father of science". Galileo's career coincided with that of Johannes Kepler.
The work of Galileo is considered to be a significant break from that of Aristotle. In addition, his conflict with the Roman Catholic Church is taken as a major early example of the conflict of authority and freedom of thought, particularly with science, in Western society.
