Jjeffn1 replied to the thread Undergrad Particle vs Wave Interpretations of QM.I am trying to understand where, from just a plausibility perspective, I would deviate from MWI. So, I think this is it, but I want to...

Jjeffn1 reacted to Matterwave's post in the thread Undergrad Particle vs Wave Interpretations of QM with
Like.
Note that, at least to my knowledge, there is no claim that universes are created only that it branches in MWI. Why is branching... -
Jjeffn1 reacted to danieltanfh95's post in the thread Seeking clarity on the physical definition of an observer with Like.
I cannot provide a single-line quotation because the two halves sit in separate literatures. The decoherence programme (Zurek, Wallace...

Jjeffn1 replied to the thread Undergrad Particle vs Wave Interpretations of QM.I have been trying to get a better understanding of what appears to be (to me) a less fantastical interpretation of the Many Worlds...

Jjeffn1 reacted to bhobba's post in the thread Seeking clarity on the physical definition of an observer with Like.
Very nice discussion. Kudos. Just as an aside, a link to the prototype QFT, What Is A Photon, so those unfamiliar can get a general...
-
Jjeffn1 replied to the thread Undergrad Particle vs Wave Interpretations of QM.I need to understand MWI better. To the extent it really requires universes to come into existence every time there is a quantum...
-
Jjeffn1 replied to the thread Undergrad Particle vs Wave Interpretations of QM.I'll dig into the book more. (I'm reading it occasionally and slowly). I suspect it doesn't make the math easier. The comparison to...

Jjeffn1 replied to the thread Undergrad Particle vs Wave Interpretations of QM.I'll try to find the exact quote. In the Introduction, p. xiii of Fields and their Quanta, Hobson writes: "Chapter 4 discusses...

Jjeffn1 replied to the thread Undergrad Is infinity a necessary concept?.When applied to the physical universe, it seems to me the concept requires some sense of continuity of the "thing" considered infinite...

Jjeffn1 replied to the thread Seeking clarity on the physical definition of an observer.My $.02 for what its worth: The term "observer" has caused so much confusion. The word "observer" implies a conscious, biological...
-
Jjeffn1 replied to the thread Undergrad Particle vs Wave Interpretations of QM.My impression is, for practicing physicists, the major difference between ordinary quantum physics and quantum field theory is the...

Jjeffn1 reacted to BillTre's post in the thread Undergrad Particle vs Wave Interpretations of QM with Like.
The Kuhn book The Structure of Scientific Revolutions came out in 1962. I read it and liked it in high school. I was a zoology major in...

Jjeffn1 posted the thread Undergrad Particle vs Wave Interpretations of QM in Quantum Interpretations and Foundations.I am curious whether undergrad physics students take courses on the philosophy of science. For example, does your syllabus include...

Jjeffn1 reacted to loop quantum gravity's post in the thread Undergrad "The wavefunction never collapses" with Like.
Eventually both QP and GR are not the end of the story of physics. And we are bound to have a new theory that it's not QP and not GR...

Jjeffn1 reacted to bhobba's post in the thread Undergrad "The wavefunction never collapses" with Like.
At our current understanding of QM, that is true. Still, some think that with future research, it may be possible to experimentally...
