Sir Isaac Newton
(1642-1727)


    Isaac Newton was the greatest scientist of his time. Newton gave many new and original ideas and propounded a number of scientific theories. Newton's greatest theory is the discovery of the gravitational pull of the Earth.

    Isaac was born in an ordinary peasant family of England in 1642 on Christmas Day. He was brought up by his grandmother as his mother married again after the death of his father. From his early childhood he showed interest in science. He graduated from Trinity College, Cambridge. From 1665 onwards, he completely devoted himself to science.

    In 1667, Newton was elected to Fellowship of Trinity. He gained self-confidence which was the inspiring moment of his life. He decided to employ his talent to dive in the ocean of scientific knowledge.

    In 1668, he made his first reflecting telescope as he was much inspired by Galileo and carried forward his work based on his experimental proofs. He founded the emission theory of light, discovered laws of motion, theory of gravity, etc. His invention of reflection Telescope made it easier study the heavenly bodies.


    His theories were published in his scientific treatise, Principia. He was conferred with the title of ‘Sir’ by Royal Society of London. His discovery of gravity of Earth was a matter of chance. One day, he observed a falling apple on the ground in his garden. Newton concluded the Gravitational Force of Earth and applied the same Principle to the movement of stars and planets in the solar system.

    In 1701, he was elected to the Parliament and later appointed as Master of the Mint, where he delivered to his utmost capacity. In 1727, he fell ill and died at the ripe age of eighty five.
