mburns's Journal: You should require your professor ...

You should require your professor of physics to diagram the interplay of Kaluza-Klein fields in coordinate free format. The diagram should imply approximately correct calculations of the electromagnetic effects even if the diagram is both scaled and sparse - the principle of general covariance. Drop that class, I say, if she cannot. If no one in the department can, you could consider leaving the university.
