PeterDonis reacted to Planobilly's post in the thread AI Is A.I. more than the sum of its parts? with
Like.
I've been reading this thread with interest but haven't posted because until recently I didn't have the operational experience to say... -
PeterDonis replied to the thread Undergrad Particle vs Wave Interpretations of QM.Bear in mind that, if you find it hard to believe that the MWI actually says this because it seems so outlandish, you're not alone. I...

PeterDonis replied to the thread Undergrad Particle vs Wave Interpretations of QM.Because the branches are decohered, and because in the overall wave function you are entangled with the cat--and both you and the cat...

PeterDonis replied to the thread Undergrad Particle vs Wave Interpretations of QM.The answer is simple: "branching" is just unitary evolution, and unitary evolution can't create or destroy anything.
-
PeterDonis replied to the thread Seeking clarity on the physical definition of an observer.It does if nobody has published the composition of the two separate lines of literature that you describe. I am closing this thread for...

PeterDonis reacted to renormalize's post in the thread Seeking clarity on the physical definition of an observer with Like.
Then it should be possible for you to cite an exposition of that composition that lies within "published work". Please do so.

PeterDonis replied to the thread Seeking clarity on the physical definition of an observer.Not if they aren't being measured. If they aren't being measured they do not have well-defined worldlines.

PeterDonis replied to the thread Seeking clarity on the physical definition of an observer.If by "unitary evolution" you mean "exactly unitary evolution all the time, even during a measurement", then yes. But that qualifier is...

My personal opinion is that Tumulka's claim is a mistake. Even so it remains unclear what Tumulka actually wants to claim, I see no way...

PeterDonis replied to the thread Undergrad Particle vs Wave Interpretations of QM.I didn't say it was. What I said is that it shows the location of the particle's impact, to within the finite resolution of the pixel...

PeterDonis replied to the thread Undergrad "The wavefunction never collapses".No, what I quoted from you assumes more than that. If you did not intend to claim this, then your post was extremely poorly worded...

PeterDonis replied to the thread Seeking clarity on the physical definition of an observer.This is true in the MWI, but it is not true in some other QM interpretations.

PeterDonis replied to the thread Undergrad "The wavefunction never collapses".To repeat something that I believe was said much earlier in this thread, this is true in the MWI, but it is not true in some other QM...

PeterDonis reacted to Matterwave's post in the thread Undergrad Particle vs Wave Interpretations of QM with Like.
I should first make a few disclaimers 1. I am no expert on Bohmian mechanics. Indeed I have not read Bohm's book on the subject. My...
