Again, look at how you would measure the interference pattern. I think that one would throw one photon at a time. And for each photon, one would need to know both the slit size and the place where it lands. Effectively measuring both x and p.

No, quantum particles don’t follow definite trajectories.. this is the whole point of the path integral approach. It envisions space as infinitely many infinitesimally small slits stacked one after another.

You can’t say it left the slot with this or that momentum and followed some definite trajectory and work backwards

We can say this only of asymptotic non interacting states, which we do in the LHC

In essence I am not arguing against Heissenbergs principle. I am arguing against applying it to a single event, when it is an expression on ensambles/many events.

But you were just applying the photon scattering to a single event saying you could work backwards and find the momentum

I know you know what you’re talking about, I just disagree with you on this point

Just out of curiosity. The probability that we talk about in QM, do you think of it as a Bayesian ir as frequentists?

I haven’t thought about it very deeply, Since I thing being an everettian is the way to go

I might be wrong, but I think thats the key point of our disagreement. Repeting experiments so that we can reconstruct known asymptotic stated may be inherently frequentists. While imagining paths from the particles point of view sounds very Bayesian to me.

Well I’m not sure about that, I try to keep my statements about QM independent of interpretation If I had to refine I would say: ‘there is no meaningful way to say a fundamental particle is in the state (x,p).’ Implying that it does not follow any trajectory

I am sure that you're familiar with the positive electron. Looking at fig1 of the Discovery paper I may be biased but that looks a while lot like a trajectory. And they understood their own magnets so well that they even measured the momentum of itpic.twitter.com/PSiWNHaPcs
