Full name: Sir Isaac Newton
Education: Trinity College, Cambridge (B.A. 1665, M.A. 1668), The King’s School, Grantham (1655-1659)

An English mathematician, Sir Isaac Newton was an astronomer and physicist who is widely recognized as one of the most influential scientists of all time and a key figure in the scientific revolution.

Newton discovered many laws and theories in optics, motion and mathematics. Newton wrote that white light was a composition of all colors of the spectrum, and that light was composed of particles. 
His momentous book on physics, Principia, contains information on nearly all of the essential concepts of physics except energy, ultimately helping him to explain the laws of motion and the theory of gravity. Along with mathematician Gottfried Wilhelm von Leibniz, Newton is credited for developing essential theories of calculus. 
Newton's first major public scientific achievement was designing and constructing a reflecting telescope in 1668. As a professor at Cambridge, Newton delivered an annual course of lectures and chose optics as his initial topic. He used his telescope to study optics and help prove his theory of light and color. 
The Royal Society told him to demonstrate his reflecting telescope in 1671. They encouraged Newton to publish his notes on light, optics and color in 1672. 
In 1687, Newton published Philosophiae Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy), most often known as Principia
In Principia, he describes the motion of bodies with three basic but very important laws of motion.

First Law

A stationary body will stay stationary unless an external force is applied to it.
Second Law

Force is equal to mass times acceleration, and a change in speed is proportional to the force applied.
Third Law

For every action, there is an equal and opposite reaction.
