# Sir Isaac Newton

and physicist, considered one of the greatest

scientists in history. He made important

contributions to many fields of science. His

discoveries and theories laid the foundation for

much of the progress in science. Newton was one

of the inventors of a mathematics called calculus.

He also solved the mysteries of light and optics,

formulated the three laws of motion, and derived

from them the law of universal gravitation. Newton

was born on December 25, 1642, at

Woolsthorpe, near Grantham in Lincolnshire.

When he was three years old, he was put in care

of his Grandmother. He then was sent to grammar

school in Grantham. Then later he attended Trinity

College at the University of Cambridge. Newton

ignored much of the established curriculum of the

university to pursue his own interests; mathematics

and natural philosophy. Proceeding entirely on his

own, he investigated the latest developments in

mathematics and the new natural philosophy that

treated nature as a complicated machine. Almost

immediately, still under the age of 25, he made

fundamental discoveries that were instrumental in

his career science. The Fluxional Method,

Newton's first achievement was in mathematics.

He generalized the methods that were being used

to draw tangents to curves and to calculate the

area swept by curves. He recognized that the two

procedures were inverse operations. By joining

them in what he called the fluxional method,

Newton developed in 1666 a kind of mathematics

that is known as calculus. Calculus was a new and

powerful method that carried modern mathematics

above the level of Greek geometry. Optics was

another area of Newton's early interests. In trying

to explain how colors occur, he arrived at the idea

that sunlight is a heterogeneous blend of different

colors of which represents a different color. And
