Two Slit paper

Ok as promised here is what I think is the definitive paper on the two slit experiment

It shows how the quantum formalism works. Most text books as Marcella points out never show a consistent explanation from the principles of quantum mechanics. The analogy is made with classical optics one never sees a quantum explanation. I really wish this paper were known more widely it's a gem.
