Sir Isaac Newton (25 December 1642 - 20 March 1726 or 1727), an English mathematician, astronomer, theologian, and physicist, is widely recognised as one of the most influential scientists of all time and one of the key figures in the scientific revolution.

Newton's "Principia" formulated the laws of motion and universal gravitation that dominated scientist's view of the universe over the next three centuries. He removed the last doubts over the heliocentric model of the solar system. He also built the first practical reflecting telescope. He made the first theoretical calculation of the speed of sound and made many contributions to the science of mathematics. Newton was even made master of the Royal Mint and was justice of the peace in all the home counties.

English poet Alexander Pope wrote the famous epitaph:

  • Nature and nature's laws lay hid in night;
  • God said "let Newton be" and all was light.
