Sir Isaac Newton when he was a boy, was more interested in making mechanical
devices than in studying. He wanted to go to college, but he didn't have the
money to go. He enrolled at the lowest entry. In this position he had to serve
the other students by running errands for them. When the university shut down
because of the plague, he went home and continued to study on his own. He had
a notebook with 140 blank pages and he began to fill them with notes as he
read and experimented. The famous apple incident led to his three basic laws
of motion: An object in motion tends to remain in motion unless an external
force stops it; an object moves in a straight line unless some force diverts
it; and for every action, there is an equal and opposite reaction. His second
discovery was about light and the properties of light. He also made a
reflecting telescope to use in his studies. Newton's third great discovery was
in the field of math when he developed a kind of math we call calculus. By
the time he was in his mid 50's he had worn himself out and suffered from
exhaustion. Some were even afraid he might have mercury poisoning caused by
his experiments. Sir Isaac Newton never married. It is said he was very
generous with his nieces and nephews and with the scientists who helped him in
his work.
