I was a little disturbed when you offered up the experiment that allowed us to reject the hypothesis about a half-mirror changing each time it reflects a photon or lets one through. How do we know there aren't other experiments that could discredit the amplitude hypothesis? I'm sure there's a good answer, but don't expect me to take too much on faith.

I also thought it was odd that you called configurations real, when they just seem to be a mathematical construct that describes the behavior of photons bouncing off of mirrors. Couldn't some other construct just as easily explain what's going on (in an equivalent fashion)? It's sort of like saying that y''+5y'+ y = 0 is as real as a spring bouncing up and down, when it's actually only a model for describing what the spring is doing. Perhaps I misunderstood what you meant by "real."

Of course these are only questions, not criticisms. This is the best explanation I've ever heard--please keep it up!
