True, but if he opined on the more esoteric parts of quantum theory and disagreed with some of it he'd deserve a commendation. Disagreement is the way science, and knowledge in general, progresses (otherwise we'd still be stuck in traps of classical physics and not have developed relativistic physics or stochastic models of thermodynamics). I believe this is true in other areas of study as well, and the disagreements and discussions are necessary. And open discussion benefits us all. Not that her opinions have to be respected or accorded any relevance on the basis of her past reputation, the ideas must be debated and stand or fall on their own.If my chemistry prof told me that CH3- was ethyl and C2H5- was methyl and that CN- was non-toxic I'd want him/her/them fired, or to seek medical treatment.
That being said, if she permitted these beliefs to enter her classroom and become the focus of a class have nothing (or nearly nothing) to do with the subject matter of the course, then by all means she should be disciplined. I had a zoology professor who taught nothing of the syllabus, and voiced his own stupid views on education, it was a waste of my money and time.
