For most of quantum mechanics you need the canonical commutation relations. This was Heisenberg's starting point, and cannot be deduced... -

Skeptical.
Mathemeatics is not invented but discovered. Evidently it underlies the relationships that eventually turn into observations and this is... -

Like.
I don't think that that's what the relational interpretation says. The crucial issue is the interpretation of entanglement, because... -

That the particles, fields, atoms, molecules and so on, exist and interact with each other. By the way I think that the analogy with... -

Are you saying that relational QM has a clear ontology? If you do, what is it? -
bhobba reacted to gentzen's post in the thread Graduate Sidney Coleman's opinion on interpretation in his Dirac lecture with
Like.
Careful, he only said "associated with Hugh Everett". Since Coleman is very careful with words, this means that he is not claiming to... -

If the geocentric model preferred by the catholic church is the metaphor for the orthodox interpretation of QM, then the heliocentric... -

I don't know whether Coleman's position contains something original, but there is something else that I find problematic. Coleman first... -

bhobba reacted to PeterDonis's post in the thread Graduate Why does QM split into two evolution types? with
Like.
It's not. It's a matter of "that's how we make accurate predictions". That's how any physical theory works: you figure out what... -
bhobba reacted to PeterDonis's post in the thread Graduate Why does QM split into two evolution types? with
Like.
No, that's not what "no collapse" interpretations (like the MWI) say. They say unitary evolution just continues, all the time. Yes, part... -
bhobba reacted to PeterDonis's post in the thread Graduate Why does QM split into two evolution types? with
Like.
Um, because that's how the theory works? And doing it that way makes correct predictions? Um, the latter? Since that "mathematical... -

I think the answer to this depends on which QM interpretation you adopt. Your step 3 (which is usually called "collapse" or "state... -

Um, yes, you are: This is challenging the established theory--just with nothing to back the challenge up but vague generalities...
