Sir Isaac Newton
Sir Isaac Newton was born in 1642 in Woolsthorpe England on
Christmas Day. His father had died three years before his birth, and
baby Isaac was not expected to survive because he was a premature
baby. As he got older he attended a Grammar school in Grantham,
where he found his love for science. The plan was for Isaac to come
back home at the age of seventeen so he could look after the farm, but
his uncle thought otherwise. His uncle, a Cambridge undergraduate,
persuaded his mom that it would be better for Isaac to go to a
university.
In 1661, Isaac went up to Trinity College where he paid his way
for six semesters by waiting tables and cleaning rooms. He was elected
a scholar and received four years of financial support. Unfortunately
the plague broke out that summer and Isaac was forced to return home.
He spent two year concentrating on problems in mathematics and
physics. During this time he studied the theories of gravitation. These
theories are mathematic formulas that explain how objects move when
a force acts on them. He explained that gravity is the force that causes
things to fall down. If a pencil falls off a desk, it will land on the floor,
not the ceiling. Along with this Newton came up with the three laws of
motion.
In 1667 Isaac returned to the university, where he began work on
chemistry and optic theories. He began to experiment with light, lenses,
and prisms. He was trying to improve the telescope. Newton’s first
major public scientific achievement was the invention, design and
construction of the reflecting telescope.
Newton had a minor set back when after a long day of work his
dog joined him in his study room. As his dog jumped on the table, he
knocked over a candle, and the room quickly went into flames. Newton
lost over twenty years of work in the fire.
Sir Isaac Newton will always be known for his many great
discoveries and witty inventions. Still today we use his laws of motion
and gravity in everyday life. I can honestly say he is one of the greatest
scientist ever.
