Does matter follow precise mathematical laws or is mathematics simply a good approximation and tool used to describe matter ? If all there is is mathematical relationships, then matter and all physics actually doesn't even exist if only as a metaphor for equations. If matter only APPROXIMATELY follows mathematical laws, then there is room for a real metaphysical universe made up of non mathematical items. Could matter and reality simply be what remains after all the equations have been calculated as a sort of error ? Matter is the "error" in our calculations, or it could be that the quantum imprecision is what gives matter some "substance" as opposed as being only mathematical items. Any ideas ?, there is always some confusion as where matter, physics starts and mathematics ends.......
