Chapter 9: Fundamental Physics

Section 5: Ultimate Models for the Universe


Physics versus mathematics

Theoretical physics can be viewed as taking physical input in the form of models and then using mathematics to work out the consequences. If I am correct that there is a simple underlying program for the universe, then this means that theoretical physics must at some level have only a very small amount of true physical input—and the rest must in a sense all just be mathematics.
