* Physics:
* Classical Mechanics: Newton is most famous for his laws of motion and universal gravitation, which revolutionized our understanding of how objects move and interact.
* Optics: He made significant contributions to optics, including experiments with prisms and the development of a reflecting telescope.
* Mathematics:
* Calculus: He independently developed calculus, a powerful tool for dealing with changing quantities.
* Algebra and Geometry: He also made contributions to these areas.
While he is most recognized for physics and mathematics, Newton also studied astronomy, alchemy, and theology to some degree. He saw these disciplines as intertwined and believed that they all contributed to a deeper understanding of the universe.
