An uncle decided that Newton would do better as a student than as a farmer. So he helped the young man enter Cambridge University to study mathematics.
Newton completed his university studies five years later, in sixteen sixty-five. He was twenty-two years old.

STEVE EMBER: At that time, a deadly plague was spreading across England. To escape the disease, Newton returned to the family farm. He did more thinking than farming. In doing so, he found the answers to some of the greatest mysteries of science.
A portrait of Isaac Newton
Newton used his great skill in mathematics to form a better understanding of the world and the universe. He used methods he had learned as a boy in making things. He experimented. Then he studied the results and used what he had learned to design new experiments.
Newton's work led him to create a new method in mathematics for measuring areas curved in shape. He also used it to find how much material was contained in solid objects. The method he created became known as integral calculus.
SHIRLEY GRIFFITH:One day, sitting in the garden, Newton watched an apple fall from a tree. He began to wonder if the same force that pulled the apple down also kept the moon circling the Earth. Newton believed it was. And he believed it could be measured.
He called the force "gravity." He began to examine it carefully.
He decided that the strength of the force keeping a planet in orbit around the sun depended on two things. One was the amount of mass in the planet and the sun. The other was how far apart they were.
