It looks like I've been missing some posts on kitty cats. I would like to point out the following: 1) Kitty cats are tangible objects. 2) Wavefunctions are mathematical functions defined over a region of space and time. They are abstract. Wavefunctions don't pass through slits. They are defined over a region which includes the slits. The fact that they are nonzero at the slits reflects the fact that if you don't look you don't know which slit the particle goes through. This is equivalent to not knowing if the kitty is dead or alive. Physicists just don't seem to understand that probability has got to do with knowledge. Probabilities are not absolute but depend on the observer. If we put Schrodingers doggy in the box with a gas mask then the "alive/dead wavefunction" collapses for him when he sees the kitty kick the bucket or not, but it does not collapse for Schrodinger. One of the reasons I gave up physics to become a mathematician was that I was sick and tired of physicists who had no understanding of basic probability theory but who continually bullshited about QM. Lets face it, the argument is not about kitty cats. The real gripe is that some people are worried about not having free will and they think that their nonsense interpretations of QM will restore their lost free will.
