Sir Isaac Newton was born in Lincolnshire, near Grantham, on December 25, 1642. His education took place at Trinity College, in Cambridge where he lived from 1661 to 1696. Here is where he studied physics and astronomy, and created calculus. Newton became interested in mathematics in the autumn of 1663 when he tried to read an astrology book but could not understand it because he had little knowledge of trigonometry and geometry. What got his mind going was when he read that parallelograms upon the same base and between the same parallels are equal. He then returned back to the astronomy book with a greater understanding and interest. In the summer of 1665, the plague closed down the University he was attending and during …show more content…
Before his time, people had believed that white light was a basic single entity, but the chromatic aberration in a telescope lens convinced him otherwise. With this hypothesis, he wrongly concluded that telescopes using refracting lenses would always suffer chromatic aberration; therefore he constructed a reflecting telescope. He delayed the publication of a full account of his optical researches until 1704, it dealt with: investigations of the colors of thin sheets, Newton’s rings, and diffraction of light. However Newton’s greatest achievement was his work in physics and celestial mechanics, which climaxed with the theory of universal gravitation. By 1966, he had created his 3 laws and of motion and also discovered the law giving the centrifugal force on a body moving uniformly in a circular path; although his understanding of mechanics of circular motion was incorrect. Newton imagined that the Earth’s gravity influenced the Moon, counter-balancing its centrifugal force. From his law of centrifugal force and Kepler’s third law of planetary motion, Newton deduced the inverse-square law. In 1687, Newton published the Philosophiae naturalis principia. The book is considered the greatest scientific book ever written. In it he analyzes the motion of bodies in resisting and non-resisting media under the action of centripetal forces. The results were applied to orbiting bodies, projectiles, pendulums, and free-fall
