My qm textbook, aptly named "quantum mechanics", is by McIntyre, though it omits the proof for the uncertainty principle and simply states it as ∆A∆B ≥ 1/2|〈[A,B]〉|. In words, if that's unclear, this is 'the product of the rms deviations of A and B is greater than/equal to one half the absolute value of the mean of the commutator of A and B. It says to look elsewhere for the proof, and normally I wouldn't be bothered, but since this leads to Heisenberg's highly unintuitive result, ∆x∆p ≥ h/4π, i feel like a proof is very necessary. If anyone could prove this for me, I'd be very greatful(adsbygoogle = window.adsbygoogle || []).push({});
