In mechanics he would create his famous three laws of motion but it’s in physics that he became most well-known for his understanding of gravity, and in mathematics for his discovery of calculus and his writing perhaps the single most important scientific book of all-time, the ‘Principia’ which is still referenced today.


Isaac Newton’s main body of work was as a physicist and mathematician. He was a part of a scientific revolution in the 17th century which would fundamentally change the way that people would see the world. In the field of optics, he would advance our understanding of light and how we saw it.
