The analogue of the relation in the classical mechanics is thus given by the relations between average values. Straub. phd pasadena. california july 23. 2005 of all the symmetries that are expressible in quantum mechanics. perhaps the most beautiful is gauge invariance. We have seen that symmetries play a very important role in the quantum theory.
