What does Newton's work?

Newton's work laid the foundation for classical mechanics, particularly through his formulation of the laws of motion and universal gravitation. His seminal work, "Philosophiæ Naturalis Principia Mathematica," describes how objects move under the influence of forces and how gravity governs the motion of celestial bodies. Additionally, he made significant contributions to calculus and optics, demonstrating that white light is composed of a spectrum of colors. Newton's insights revolutionized science and remain fundamental to our understanding of physics today.
