1 Sir Isaac Newton was an English mathematician and mathematician and physicist who lived from 1642-1727. 2  The legend is that Newton discovered Gravity when he saw a falling apple while thinking about the forces of nature.
Then came Isaac Newton (1642-1727) who brought the laws of physics to the solar system. Isaac Newton explained why the planets move the way they do, by applying his laws of motion, and the force of gravitation between any two bodies, letting the force decrease with the square of the distance between the two bodies.
