>But quantum mechanics limits any combination of these two quantities to discrete multiples of Planck's constant, h.
This sounds wrong to me. My understanding of QM is that the underlying physics is actually continuous (as apposed to quantized), and it is only when we attempt to make measurements that we run into planks constant.
