Reality is the semantics, mathematical models are the syntax. Mathematical models always need a human to map them to reality.

Also I think there is a difference between theorems and theories: Theorems are purely mathematical, they can be proved. If they haven't yet been proved thay are just a conjecture. Theories are the maps between models and reality, they can only be disproved (not proved).
