SIR ISAAC NEWTON


Newton was born on December 25,1642. He was an English


mathematician and physicist, considered one of the greatest


scientist in history, who made important contributions to many


fields of science. His discoveries and theories laid the


foundation for much of the progress in science since his time.


Newton was one of the inventors of the branch of mathematics


called Calculus. He also solved the mysteries of light and


optics. Formulated the three laws of motions, and derived from


them the law of universal gravitation.


Newton?s birth place was at Woolsthorpe, near Grantham in


Linclonshire. Where he lived with his widowed mother, Until


around his third birthday. At this time his mother remarried,


leaving him in the care of his Grandmother and sent to grammar


school in Grantham. Later, in the Summer of 1661, he was sent to


Trinity Collage, at the University of Cambridge. Newton received


his bachelors degree in 1665. After an intermission of nearly two


years to avoid the plague, Newton returned to Trinity, Which


elected him to a fellowship in 1667. He received his master


degree in 1668. Newton ignored much of the established curriculum


of the University to pursue his own interests: mathematics and


natural philosophy.


By joining them in what he called the Fluxional method,


Newton developed in the autumn of 1666 a kind of mathematics that


is now known as calculus. Was a new and powerful method that


carried modern mathematics above the level of Greek geometry.


Although Newton was its inventor, he did not introduce calculus


into European Mathematics.


Always Fearful of publication and Criticism. Newton kept his


Discovery to himself. However, enough was known of his abilities


to effect his appointment in 1669as a Luciasian Professor of


Mathematics at the University of Cambbridge.


Optics was another area of Newton?s early interests. In


trying at explain now colors occur, he arrived at the idea that


sunlight is a heterogeneous blend of different rays each of,


which


represents a different color-and that reflections and


refraction cause colors to appear by separating the blend into


its components. Newton demonstrated his theory of colors by


passing the beam of sunlight through a type of prism, which split


the beam into se

parate colors.


In 1672 Newton sent a brief exposition of his theory of


colors to the Royal Society in London. In 1704 however, Newton


published appliqu?s, which explained his theories in details.


During


the following two and a half years, Newton established the modern


science of dynamics by formulating his three laws of motion.


Newton applied there laws to Kempler?s law of orbital


motion-formulated by the German astronomer Johannes Kempler-and


derived the law of Universal Gravitation. Newton is probably best


known for discovering Universal Gravitation, which explains that


all bodies in space and on earth are affected by the force of


Gravity, and another thing he invented was the Reflecting


Telescope. He published this theory in his book Philosophiae


Natural is Principia Mathematica in 1687. This book marked a


turning point in the history of science; it also ensured that its


author could never regain his privacy.


In the same year, 1687, Newton helped lead Cambridge?s


resistance to the efforts of King James II to make the University


a Catholic institution, After the English Revolution in 1688,


which drove James from England, the University elected Newton one


of its representatives in a special convening of the county?s


Parliament.


In the summer of 1693 Newton showed symptoms of a severe


emotional disorder. Although he regained his health, his creative


period had come to an end. Newton?s connections with the leaders


of the new regime in England led to his appointment as warden.


And later master of Royal Mint in London, where he lived after


1696. In 1703 the Royal Society elected him President, an office


he held for the rest of his life. As President, he ordered the


immediate Publication of the Astronomical Observations of the


First Astronomer Royal of England, John Flamsteed. Newton needed


these observations to perfect his Lunar theory.


Newton also compiled the book of evidence that the society


published. The effects of the quarrel lingered nearly until his


death in 1727.


In addition to science, Newton also showed an interest in


Alchemy, Mysticism, and Theology. Many pages of his notes and


writing-particularly from the later years of his career are


devoted to these topics. However, historians have found little


connection between these interests and Newton?s scientific works.
