Full Answer

Sir Isaac Newton was born on Dec. 25, 1642. He grew up in England and went to school at The King's School in Grantham. As Newton grew older, he attended Trinity College in Cambridge. It was here that he studied the teachings of Aristotle, Descartes and Galileo. It was also at Trinity College that Newton formulated his binomial theorem, which later led him to discover calculus. When his school closed as a precaution due to the Great Plague sweeping through Europe, Newton went home to study with private tutors.

At home he invented the theory of gravity and wrote the universal law of gravitation equation. Also while at home, Newton studied optics and invented the reflecting telescope by improving upon the earlier refracting telescope. In addition Newton also postulated the Three Laws of Motion. In these laws, Newton describes the relationships between force, matter and acceleration. He can also be credited for many inventions that people still use today including the pet door and the color theory.
