** Explanation: **
Sir Isaac Newton changed the world. Born in 1643,
Newton was only an
above-average student. But he went home from
Cambridge one summer in 1665,
thought a lot about the physical nature of the world, and came back two
years later with a revolutionary understanding of
mathematics,
gravitation,
and
optics. A
Professor of his, upon understanding what
Newton had done,
resigned
his own position at
Cambridge so
Newton
could have it.
Newton's
calculus
provided a new mathematical framework for the rapid solution of
whole classes of physical problems.
Newton's
law of
gravitation explained
in one simple formula how apples fall and planets move.
Newton's insights
proved to be so overwhelmingly powerful he was the
first
scientist ever knighted.
