swaha Posted August 14, 2009 Share Posted August 14, 2009 Is there any proof of the uncertainity principle without the use of braket vectors? If so please send me where to find it. Link to comment Share on other sites More sharing options...
ajb Posted August 14, 2009 Share Posted August 14, 2009 I don't think so as the general uncertainty principle depends on the states and in particular the commutator of the operators involved, roughly we have [math] \langle \psi | [A,B] |\psi \rangle [/math]. It is because the commutator for the position and momentum is ~ i (in nice units) that the uncertainty principle does not depend on the states.
