Thus, even in his boyish games, he was searching out the secrets of nature and could find out difficult things in simple ways. His brain was always busy observing different phenomena of nature.
1. When Isaac was fourteen years old, his mother took her son from school to help her on the farm at Woolthorpe, where she lived with three other children - Isaac’s brother and two sisters. For more than two years he worked on the farm and then his mother sent him back to school to pre¬pare for University.
2. On June 5, 1661, Newton entered the University of Cambridge where he studied mathematics. Soon he became famous having made a number of important contributions to mathematics by the time he was twenty-one.
3. When Newton was twenty-two years old he began studying the the¬ory of gravitation. In 1665, while on a visit in his native village, he saw an apple fall from a tree and began wondering what force made the apple fall Then he began to think “of gravity extending to the orb of the moon” and immediately put this idea to the test of calculation.
4. While at Cambridge Newton had read with great interest the writ¬ings of Galileo, he knew the geometry of Descartes, and he had already partly worked out the methods of calculus, which he called the method of fluxiona.
5. Newton performed many experiments with tight and found that white light was made up of ray of different colours. He invented the ra- flecting telescope that was very small in diameter, but magnified objects tuforty diameters. Newton developed a mathematical method which is now known as Binomial Theorem and also differential and integral calculus.
6. In 1669 he was appointed professor and began to lecture mathema¬tics and opdcs at Cambridge.
