> real numbers are simply too powerful to be resolved in the physical world

In a sense "real" numbers are in fact not real at all because they can't physically exist. I think we got it wrong when these numbers were named. What we now call the 'whole' numbers should be called 'real', and vice versa. pi is a whole (in the sense of complete) number because it includes ALL decimal places, but because of infinite precision it can never be realized. 2 is a real (as in it is realizable) number because we can have two of something in reality.
