As of 2014, the title "Father of Physics" has not been given to a single scientist. Isaac Newton, Albert Einstein, Galileo, Thales of Miletus and Aristotle, however, are some of the scientists who are greatly remembered for their noteworthy contributions and are among the great contenders for the title.
Newton, Galileo and Einstein have all been called "Fathers of Modern Physics." Newton was called this because of his famous law of motion and gravitation, Galileo for his role in the scientific revolution and his contributions on observational astronomy, and Einstein for his groundbreaking theory of relativity. More scientists contributed to the field of physics, including Thomas Edison, Nikola Tesla, Gottfried Leibniz, Blaise Pascal, Michael Faraday and Allesandro Volta.
