But the teaching of quantum physics should clearly explain where we are deviating from classical physics and why. This, in my opinion, is done most clearly by demonstrating how the formal Schrödinger equation can be recovered purely from classical physics through formal algebraic steps; but then how it can be reinterpreted, with additional solutions (which are linear combinations of classical solutions) that make no sense whatsoever in the classical world.
Emphasize, then, that this purely mathematical abstraction (no room for intuition here!) actually, accurately describes our physical world. That Nature is under no obligation to appeal to our intuition, and that from this point onward, the math needs to be trusted (after it is validated by experiment, of course).
If, instead, the “old” quantum theory is taught first (that is to say, all those experiments and empirical relationships that constituted the quantum theory back in the early 1900s before Schrödinger and Heisenberg), if Schrödinger’s equation is presented as an ad hoc thing or an equation that is obtained through ill-defined formal “promote-to-operator” rules, if the student is then hopelessly confused by silly, and completely unnecessary “interpretations”… then that student will be like I was for many years, wondering in the dark, trying to make sense of a confusing, incomprehensible mess, until (if he is lucky) he happens upon a few good books (Kleinert’s book on path integrals was one of the eye-openers for me, especially the introductory chapters) that finally help untangle this mess.
