Like.
Not if they aren't being measured. If they aren't being measured they do not have well-defined worldlines. -
QuarkyMeson replied to the thread AI Is A.I. more than the sum of its parts?.Planobilly, why are you using AI output to respond to these messages? The "not that -> this" constant "framing" is 100% characteristic...

QuarkyMeson reacted to renormalize's post in the thread Seeking clarity on the physical definition of an observer with Like.
Even though I have read the Bell paper you cited, I am, alas, not knowledgeable enough about "beables" to intelligently advise you. That...

I cannot provide a single-line quotation because the two halves sit in separate literatures. The decoherence programme (Zurek, Wallace...

The statement above embeds three mischaracterizations worth addressing individually. "Admission" mischaracterizes my statement. That...

QuarkyMeson replied to the thread Seeking clarity on the physical definition of an observer.I agree more or less, but that was essentially my point. The proposed definition of observer is excessively broad. If an SR-observer is...

QuarkyMeson replied to the thread Seeking clarity on the physical definition of an observer.Sure, although it started as "anything with its own Dirac current." Now it's "anything with an aggregate fermion current." That's every...

Agree.
This is true in the MWI, but it is not true in some other QM interpretations. -
QuarkyMeson replied to the thread Seeking clarity on the physical definition of an observer.The Dirac current only exists for fermionic fields, so this definition excludes photon detectors and any macroscopic observer. A person...

If your only requirement to call something a "one-particle state" is that it's an eigenstate of the number operator @Matterwave wrote...

QuarkyMeson replied to the thread Seeking clarity on the physical definition of an observer.Fair. My take on OPs questions: 1. It doesn't say anything about it at all. SE describes unitary evolution of a state vector under a...

QuarkyMeson replied to the thread Seeking clarity on the physical definition of an observer.A continuous superposition of momentum eigenstates can still be a one-particle state, no?

#151, QuarkyMeson The post still seems unfocused but in trying to interpret, I feel like you and I and hopefully others want the forum...

QuarkyMeson replied to the thread Announcement PF Style 2026.Even complaining is fine. :devil: So for example here, when I was logging in, you're hit with what I would call "taglines"; i.e...

QuarkyMeson replied to the thread Announcement PF Style 2026.My only feedback is that some of the taglines are a bit too preachy and anti-LLM for my tastes. The forum/discussions should stand on...
