what are integrals good for if the universe is discrete?

>>	Anonymous Sun Nov 25 16:02:40 2012 No.5289282 >>5289277 Numerical Approximations. Protip: 'planck units' are very tiny.

>>	Anonymous Sun Nov 25 16:03:25 2012 No.5289288 >>5289277 Why shouldn't you be able to have integrals on a discrete measure space?

>>	Anonymous Sun Nov 25 16:17:10 2012 No.5289353 What the fuck does that matter? Math doesn't care about the implementation of our universe. Only we do, when we try predicting its behaviour. In which case we care about provability as well.

>>	Anonymous Sun Nov 25 16:24:25 2012 No.5289401 So instead of actual integration, its a Riemann sum with discrete size that, while small, aren't infinity. Nothing is broken anymore.
