Sir Isaac Newton

Why was he famous?

Isaac Newton was born in 1643 and became famous for his work on gravity and his three laws of motion. He was also well known for his work on light and colour, and what is now called calculus (a branch of mathematics).

The famous story of an apple falling to the ground from a tree illustrates how Newton’s work on gravity was inspired by things he observed in the world around him.

Top 10 facts

  1. Isaac Newton is best known for ‘discovering’ gravity, but he worked on so many different topics that our understanding of the world was changed forever by his work..
  2. Newton had many roles in his life beyond his scientific research: he was Warden and Master of the Mint, and President of The Royal Society, as well as a member of parliament (MP).
  3. Newton was born very early (premature) and his family thought he would die, but he actually went on to live to the age of 85.
  4. Newton was a grumpy man and often argued with people.
  5. Newton discovered that white light is made up of a range of colours.
  6. Newton’s mum wanted him to become a farmer. Newton had other ideas!
  7. Newton initially studied for a law degree at Cambridge University. During this time he bought a book on maths but didn’t understand it.
  8. Newton owned more books on history than on science.
  9. When he was an MP, Newton only ever spoke one sentence – and that was to ask for a window to be closed!
  10. Newton was knighted by Queen Anne on April 16, 1705.

Did you know?

  • Isaac Newton was not very keen on school work and preferred reading and making things.
  • Newton was the first person to build a reflecting telescope, which made the images seen through a telescope much clearer.
  • Newton was the first scientist to be buried at Westminster Abbey. Since then other scientists have been buried there, including Charles Darwin, Ernest Rutherford, and Sir JJ Thompson.
  • Newton studied maths, physics and astronomy at Cambridge University. He became Professor of Mathematics and worked at the university for over 30 years.
  • Newton was also interested in alchemy – he spent a lot of time trying to discover how to change things like lead and mercury into gold.
  • Forces are measured in ‘Newtons’ after Newton’s work on motion.
  • Sometimes Newton’s year of birth is reported as 1642 and sometimes as 1643. This is because according to the old (Julian) form of calendar he was born on the 25th December 1642, but under the Gregorian calendar that we use today he was born on the 4th January 1643!
