Isaac Newton
Sir Isaac Newton was a famous English physicist and mathematician. Some of his accomplishments were his three laws of motion, the basic principles of modern physics, and the formulation of the law of gravitation. He was also the original discoverer of the infinitesimal calculus. There are many portraits of Isaac Newton out there, so we have a pretty good idea of what he looked like during his lifetime. The depiction of what he might look like today seems to be very accurate.
