Newton's Principia

We visited the Royal Society in London to learn about one of the most influential scientists in history and his famous publication. Sir Isaac Newton's Principia was first published on 5th July 1687 and contains many ground breaking discoveries. Within the pages you can find Newton's famous laws of motion, his theories on gravity and his work on the motion of the planets. Professor Martin Rees (President of the Royal Society) tells us about Newton's work and we peer into the pages of the Principia.
