His theory of light and optics transformed that field, too. His extraordinary synthesis of the work of Copernicus, Kepler and Galileo transformed the physical sciences fundamentally. So, for example, his laws of motion and gravity are still part and parcel of how we think about the physical world (Einstein and Heisenberg notwithstanding). Newton was without doubt the preeminent scientific mind of his day and was voted largely unopposed to the post of President of the Royal Society (the leading scientific community of his day).

For all his talents and achievements he was not a nice man; not an easy person to love; not even very pleasant company. He was widely reported1:
