The Extraordinary Mathematician Sir Isaac Newton

Sir Isaac Newton was born on January 4, 1642, in the town of Woolsthorpe, near Grandtham in Lincolnshire. English mathematician and scientist who invented differential calculus and formulated the theories of universal gravitation, terrestrial mechanics, and color. His study on gravitation, presented in Principia Mathematica (1687), was supposedly inspired by the sight of a falling apple.

When he was three years old, his widowed mother remarried, leaving him to the care of his grandmother. He was soon then persuaded to go to grammar school in Grantham after his mother was widowed a second time. He was sent to Trinity College, at the University of Cambridge in the summer of 1661.

In 1665 he received his bachelor’s degree. After an interval of nearly two years, to avoid the plague, Newton returned to Trinity, which elected him to a fellowship in 1667. He received his masters degree in 1668. Newton disregarded much of the established program of the university to his own interests. Those were 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 complex machine. Almost instantaneously, he made fundamental discoveries that were instrumental in his career in science. He died at the age of 84 on March 20, 1727 at Kensington, London.

Newton’s first law of motion is an object at rest or in uniform tends to stay at rest unless acted on by an outside force.

Newton’s second law of motion is during the interaction of any two objects, the mass times the acceleration of one object always equals the mass times the acceleration of another object.

One Newton is the force needed to accelerate one kilogram at the rate of one meter per second squared.

Newton’s third law of motion is for every action there is an equal and opposite reaction.

The box is pushing down on the floor with the same amount of force the floor is pushing up on the box.
