Who was Sir Isaac Newton?
Sir Isaac Newton is one of the greatest scientists who have ever lived.
Born in 1642 Isaac Newton had a lasting impact on astronomy, physics,
and mathematics. His father died before he was born and so Newton had
a difficult childhood. His mother remarried when he was just three, and
he was then sent to live with his grandmother. After his stepfather died,
his mother brought him home to Woolsthorpe in Lincolnshire, where she
wanted him to become a farmer. However an uncle noticed how clever
he was and he eventually made it to Trinity College, Cambridge
University.
Many of his great ideas came in 1665-66, when he spent time back at
Woolsthorpe while Cambridge was closed because of the plague. Among
his many achievements were the invention of the reflecting telescope,
the basic design behind all large telescopes used today; the invention of
some mathematics known as calculus, which is very useful in science
today; the discovery of the three laws of motion; and the development of
the law of universal gravitation: the theory that all objects fall at the same
rate without air resistance.
When still in his mid-twenties, he was named Lucasian Professor of
Mathematics at Cambridge University, a post now held by Stephen
Hawking.
He died in 1727 and is buried in Westminster Abbey.

Sir Isaac Newton’s Laws of Motion
Newton was a clever man.
An avid scientific fan.
He questioned many things he saw.
Like ones we had no answers for.
He thought them through right to their cores.
Then gave us many handy laws.
Newton’s First Law Of Motion:
Without a force of push or pull
an object will remain quite still.
With just one push at just one time
that object moves in one straight line.
Newton’s Second Law Of Motion:
A bigger Force accelerates
an object that is heavy-weight.
While objects of a smaller mass
don’t need much Force to move them fast.
So Newton noticed they obey
that Force will equal m times a.
Newton’s Third Law Of Motion:
Now bend a stick. Before it cracks
you’ll feel its force of pushing back.
For every action there will be
an equal one – opposingly.
Without his formulas in place
we’d soon get lost in outer space.
So Isaac’s Laws help us traverse
the reaches of our universe.
