Here are some facts about Sir Isaac Newton.

- Isaac Newton was an English mathematician, and one of the most influential scientists ever. He created laws on gravitation and motion which would be used for 300 years.
- Newton was born in Lincolnshire on 25th December 1642. He attended Trinity College, Cambridge where he worked waiting tables, and at the age of 23 developed a mathematical theory that would become infinitesimal calculus.

- Isaac Newton escaped the effects of the plague in 1665, by being sent home from college for 2 years. During this time, he came up with his theories on gravity, optics and light.
- Along with the astronomer Edmond Halley, Newton invented a reflecting telescope in 1688, and carried out experiments on the composition of light.
- He became president of the Royal Mint in 1696 and was knighted in 1705.
- Apparently, Newton came up with his well known theory of gravity after seeing an apple fall from a tree. An apple tree in the garden of Newton’s birthplace is said to be the one that produced the fruit that inspired him.
- His most important work was published in 1687. The
*Mathematical Principles of Natural Philosophy*showed how all objects in the universe were affected by gravity in the same way. - Isaac Newton was elected as a Member of Parliament in 1689, serving for exactly a year. During that entire time, the only thing he ever said was a request to shut the window.
- Newton was fascinated by alchemy, the turning of metals into gold. He was also fascinated by

- Newton has been portrayed in various episodes of Star Trek and Dr. Who. He was also the last person to appear on British £1 notes, from 1978 to 1988.
- Because Newton was born on December 25th, some people refer to the holiday Newtonmas instead of Christmas. Apples and science themed gifts are popular with followers.
