Description
As has been recently pointed out by Pagnoni et al. [[1]], care is required in applying the Heisenberg uncertainty relations. This care has sometimes been insufficiently realised in pedagogical settings. A case in point is the hydrogen atom. Here the singularity of the Coulomb potential causes difficulties in utilising the uncertainty relations. Clarification of this point is expected to improve both the learning and teaching of physics.
