Voyages of Discovery: Copernicus to the Big Bang http://edu-observatory.org/olli/VD-C2BB/Week2.html Quoting from my dad's old college General Physics book written in the early 1900s, "What we may properly call the birth of modern physics, however, dates from Galileo (1564-1642), one of the most remarkable men who ever lived. More than any one of his predecessors or contemporaries he introduced 'controlled experiment' as a means of gaining knowledge of nature". Similarly Johannes Kepler (1571-1630) discovered his laws of planetary motion and is widely acknowledged as the "Father of Modern Physics" for his use of observational data (mostly Brahe's) and the application of mathematical modeling to astronomical data.
