While reading the various posts here on PF over times that deal with "interpretations" of quantum physics, I got the impression, that it is best to concentrate on the mathematics behind the models and less - or better not at all - about any comparisons with macroscopic similarities. Apparently one can always find aspects, at which they are doomed to fail, regardless which interpretation one favors. Funnily enough, nobody seems to bother that we cannot really imagine the shape of a unitary group or operator, or an infinite dimensional Hilbert space either. Those concepts are taken for granted and nobody is arguing over their "reality". However, as soon as it comes to wave functions, various debates get started. So my 2 ct are: don't bother "reality", take the math instead and always remember, that nobody has ever seen a "real" circle, but this doesn't prevent us from dealing with them.
