Sir Issac 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 sepaThis is ONLY a preview of the article. If you would like to view the entire document, you must subscribe to Electronic References. Please register below now!
