Physics

The science of physical laws, also called physics.

It is the scientific study of matter and energy and the relations between them.

The physical science describes how things behave in space and time. It is an exact science, that is, it allows calculation of exact values for everything it describes.

Isaac Newton was not the first person to use Mathematics to describe the physical world, but he was among the first to create a system of Mathematics that let people predict events using Mathematics. One reasons Newton invented Calculus was so he could predict the movements of planets. At about the same time, Gottfried Leibniz also invented Calculus. The two men fought over Calculus, but Mathematicians give both of them credit for the invention.
