Who formulated the law of universal gravitation?

Isaac Newton

Isaac Newton forever changed our understanding of the universe by formulating the law of universal gravitation in his work "Philosophiæ Naturalis Principia Mathematica," published in 1687. This law explained why apples fall to the ground and how planets orbit around the Sun. In doing so, Newton laid the foundations of classical physics and marked the beginning of the modern scientific revolution. His contribution to science is so profound that it continues to influence physics and astronomy today.
