Isaac Newton Born

December 25, 1642

A premature, sickly baby, small enough to fit in a quart mug, was born on Christmas Day at Woolsthorpe Manor in Lincolnshire, a few months after his father's death. He was not expected to survive. He would live eighty-four years and remake human understanding of the physical universe, leaving behind a legacy that still governs how we calculate the motion of worlds.
