Love.
I'm not sure what you mean. But I might be the wrong person to ask, since my own take on QM interpretations is that, while they can be... -
bhobba replied to the thread Undergrad Help me understand indeterminism in standard quantum mechanics.Not when looked at carefully. What Bohr and some other adherents did say (unecessaryily IMHO) was it was complete. That Einsten...

bhobba replied to the thread Undergrad Help me understand indeterminism in standard quantum mechanics.That you must interpret QFT - not QM. Art Hobson did that in his book I referenced. While I currently advocate that interpretation...

Like.
No, Copenhagen basically says that we can't even know any "ontology" over and above the probabilistic predictions QM makes for... -

A standard Copenhagen-like interpretation doesn't take any position about what is really happening with "the evolution of the universe"...

But only if you force the exact same input state each time--which has to include the unobservable particle positions as well as the wave...

bhobba replied to the thread Undergrad Help me understand indeterminism in standard quantum mechanics.The answer is interpretation-dependent. In many worlds, for example, it is fully deterministic. Copenhagen - no. Decoherent...

Here is a nice explanation of the PBR theorem by Maudlin: He only acknowledges the assumption of statistical independence, so you...

That role is interpretation dependent. In some interpretations, such as the MWI, there is no actual randomness anywhere; everything is...

IMHO, as a casual amateur, geometric algebra (and geometric calculus) goes a long way to demystifying the subject. Unfortunately, it...

bhobba replied to the thread Graduate Quantum measurement problem (ie double slit experiment) question.Interestingly, Sean Carroll thinks even that is a fiction that physicists tell themselves. He thinks it emerges from something deeper...

I found out a little bit about Einstein recently regarding his trip to Manchester June 9th 1921. I was surprised to find out that he...
