What did Newton do with calculus?

Isaac Newton used calculus to revolutionize our understanding of the physical world. His applications of calculus were particularly significant in:

• Physics: He used calculus to derive his laws of motion and universal gravitation, which are the foundation of classical mechanics.
• Astronomy: He applied calculus to predict the orbits of planets and comets, making significant contributions to the field of celestial mechanics.
• Optics: Newton used calculus to study the properties of light and develop the theory of color, leading to significant advancements in optics.

Overall, Newton's calculus provided a powerful mathematical tool for analyzing and understanding the natural world, and its impact is still felt today.
