Why was Isaac Newton important?

Answer 1

Isaac newton was a physicist and mathematician. He wrote the book "Principia," which summarizes his laws of classical physics and calculus.

Isaac Newton is the father of Physics. It was he that worked out that light is made up of 3 colours combined (red, blue & green) by means of a glass triangular prism. He devised several laws of physics that we still refer to today, most notably his 3rd law of Relativity. Anyone? Every action has an equal and opposite reacton. The unit for measuring forces is named after him.

There is a lot more to say about Isaac newton but sadly I don't know it all.

He was the first one to discover gravity!*

Answer 2

Isaac Newton (1642–1727) is best known for having invented the calculus in the mid to late 1660s (most of a decade before Leibniz did so independently, and ultimately more influentially) and for having formulated the theory of universal gravity — the latter in his Principia, the single most important work in the transformation of early modern natural philosophy into modern physical science.
