Tell that to physicists who have been grappling with the limitations of the classical model for the last 50 years ... we can model our own directly perceived reality well enough but once we get out into the depths (e.g. quantum levels) it all breaks down. My laymans opinion is not that these systems are necessarily unpredictable or unstable, just that they're so far outside the scope of our normal experience we simply can't comprehend them in any intuitive way. Save for a few gifted souls of course! The classic "Rationalist" (as in Kant) explanation of mathematics is that things like pi are an a priori concept, or phenomena. An ideal if we will, that is innate within us that helps us to explain the reality without (the noumena). Mathematics relates to the interrelation of these concepts. Physics is a (very successful) attempt to relate these apriori phenomena concepts directly to the noumena. Again, just a have-a-go layman on the philosophical front as well and I welcome any corrections or more sophisticated elaborations!
