Newton disliked farming, so his mother gave up making him a farmer and he went back to the grammar school again, and then he went to Trinity College of Cambridge.
In 1667 Isaac Newton was elected a fellow of Trinity College and a member of the Royal Society. He was Lucasian professor of mathematics from 1969 to 1702, which Stephen Hawking would be in the distant future. When he was at Cambridge, he got acquainted with professor Isaac Barrow who was a great admirer of Isaac Newton’s ability. Newton set out his theories of gravity, binomial theorem, derivation etc.
Regarding the gravity, it came into his mind when he relaxed with meditation and saw the fall of an apple. He thought why apples always fall to the ground straight, do not go sideways or upwards. He also discovered many things about light and designed a reflecting telescope. His paper about light and colors is very famous even now. He was died at the age of 84 in 1727, but his many ideas are important for all physicists today.
