none, though he DISCOVERED the the laws of motion and gravitation.
Newton worked in various different areas of mathematics and physics. This question needs to be a bit more specific.
Calculus is a form of mathematics developed by Isaac Newton.
Isaac Newton did not create any subjects in school, but he made significant contributions to various fields such as mathematics, physics, and astronomy. His work laid the foundation for the development of modern physics and calculus.
Isaac Newton was the Lucasian Professor of Mathematics in the Unviersity of Cambrdige.
Alchemy, the 17th century version of Chemistry or more specifically metallurgy...was his one of the favorite subjects, the other was theology...it was one of the most popular study subject of 17th century Europe.
Isaac newton is a mathematician and a physicist, it is obvious that he has been studying mathematics and science.
Newton "invented" "applied mathematics" and calculus.
Isaac newton's favorite subject was chemistry. He was admitted to Cambridge University in 1661 and also had a great interest in mathematics.
Newton's development/invention of Calculus makes him a great mathematician. Calculus is likely the greatest invention in mathematics. Newton's Physics. Newton's great book, Mathematical Principles of Natural Philosophy (Principia), is the foundation of Physics and Modern Mathematics. Many Physicists know mathematics as a tool, and miss the Mathematical Principles that underlie Physics. Newton was a Creative and Applied Mathematician. The mysteries of Dark Energy, Dark Matter and Quantum Theory indicate inadequate understanding of the Mathematical underpinnings of Physics. Quaternion Mathematics is the mathematics of Physics. Newton's Laws reflect this Quaternion Mathematics in places but not completely.
