comment Is it the act of measuring a quantum particle that causes it to lose its uncertainty?
Thanks so much Ron, that really helps. I will be back with a follow up question, once I clear my head. Did you read about the theory that the wave function may be something which actually exists, rather than just a handy mathematical construct? I feel a crossover here but can't see it yet, but it is there I am sure.

Thanks for the responses guys. I guess what I am getting at is: In the classic double slit experiment you get the interference pattern. But if you put a detector, lets say at slot B, which will detect the passage of the photon but not block it, you get what I call the particle stripes pattern. Now, we only measured the photon at slot B. If we get a hit on the screen, but don't see the photon go through slot B, we know that the photon must have gone through slot A. So, we can infer with confidence the route of the photon without having measured it. Does it's wavefunction collapse? If so why?
