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.
