A:
I'm not good at typing symbolic formulas in this site, but here's a link to a site with a nice concise proof:
http://en.wikipedia.org/wiki/Uncertainty_principle.
The proof assumes that the physical state of an object is a quantum mechanical state, and the the probabilities of seeing different values for the position and momentum are given by the standard quantum mechanical operators.
