I just read the New Scientist article Quantum Rebel last night about Shariar Afshar's work on the double slit experiment. Ingenious as the experiment is, I really don't think it says anything about different interpretations of QM. Indeed, the outcome of the experiment is just what I'd expect from

This is confusing because I believe p has two different meanings. One is that I have written down p with a number in front of it, as one of my theorems. The other meaning is the string Bp. But that string only has meaning from the perspective of an outside observer. To me, as the machine, it is
