Demystifier replied to the thread Graduate Sidney Coleman's opinion on interpretation in his Dirac lecture.No. The beable does not need to be an additional variable. For example, in the many world interpretation the beable ##\lambda## is the... -
Demystifier replied to the thread Graduate Sidney Coleman's opinion on interpretation in his Dirac lecture.No. The ##\lambda## is what Bell calls a beable, which does not necessarily need to be hidden. -
Demystifier replied to the thread Graduate Sidney Coleman's opinion on interpretation in his Dirac lecture.No, I mean the Bell's ##\lambda##. I think it is implicitly, if not explicitly. Then I don't understand what you mean. Can you quote... -
Demystifier replied to the thread Graduate Sidney Coleman's opinion on interpretation in his Dirac lecture.Is there such a thing as a state of existence? If not, then there is no clear ontology. I meant the block universe interpretation. I'm... -
Demystifier replied to the thread Graduate Sidney Coleman's opinion on interpretation in his Dirac lecture.I don't think that that's what the relational interpretation says. The crucial issue is the interpretation of entanglement, because... -
Demystifier replied to the thread Graduate Sidney Coleman's opinion on interpretation in his Dirac lecture.Are you saying that relational QM has a clear ontology? If you do, what is it? -
Demystifier replied to the thread Graduate Sidney Coleman's opinion on interpretation in his Dirac lecture.If the geocentric model preferred by the catholic church is the metaphor for the orthodox interpretation of QM, then the heliocentric... -
Demystifier replied to the thread Graduate Sidney Coleman's opinion on interpretation in his Dirac lecture.I don't know whether Coleman's position contains something original, but there is something else that I find problematic. Coleman first... -

Demystifier replied to the thread Graduate Why is 0 K unattainable?.You are right. If the lowest possible energy is positive, then the factor ##e^{-\beta H}## vanishes at zero temperature even for the... -
Demystifier replied to the thread Graduate Why is 0 K unattainable?.The 3rd law of thermodynamics, that zero temperature cannot be attained, cannot be derived within thermodynamics itself. For that, one... -
Demystifier replied to the thread Undergrad The equivalent concept of phase change in classical mechanics.The phase of the wave function is analogous to the Hamilton-Jacobi function ##S(x,t)## in classical mechanics. If ##S(x,t)## is a... -
Demystifier reacted to Marty4691's post in the thread Graduate Why Does the Standard Model Use Six Dimensions for Probability Calculations? with
Skeptical.
So, here's the thing. The SM uses a six dimensional mathematical space to crunch probabilities. That is, one with three space dimensions... -
Demystifier reacted to Jaime Rudas's post in the thread Graduate Did Stephen Hawking fix his numerical mistake? with
Informative.
I disagree. This text is certainly not a textbook or a peer-reviewed paper, but it can't be considered a pop science book or anything...
