PeterDonis's latest activity
-
PeterDonis replied to the thread I Is there a bad intuition or bad explanation in quantum entanglement?.I'm not sure I understand. The definition of an entangled state of a quantum system is simple: it's a state that can't be expressed as a... -
PeterDonis replied to the thread I Energy*time uncertainty for particle decay.But have you studied QM from an actual QM textbook? It doesn't seem like it; it seems like you've been trying to learn it from the same...

PeterDonis reacted to PeroK's post in the thread I Energy*time uncertainty for particle decay with
Like.
A lot of what passes for QM in non-specialist courses is a messy hybrid of QM and classical thinking, IMHO. If I could explain why... -
PeterDonis replied to the thread A Dirac's integral for the energy-momentum of the gravitational field.Schutz is taking a different viewpoint from the one I described in post #13. I really wish you'd actually read that post and respond to...

PeterDonis replied to the thread I Gravitational self-interaction: another attempt to replace Dark Matter.Personally I'm skeptical of Deur's claims, but his work doesn't look to me like handwaving.

PeterDonis reacted to JimWhoKnew's post in the thread I Energy*time uncertainty for particle decay with Like.
Did you mean: ? (my favorite Griffiths quotation)
-
PeterDonis replied to the thread I Energy*time uncertainty for particle decay.I note you say (classical). Those textbooks are not focused on QM; they might cover it, but they're not primarily QM textbooks. Which...
-
PeterDonis replied to the thread I Question about discussions around quantum interpretations.After some cleanup, the thread is reopened.
-
PeterDonis replied to the thread I Energy*time uncertainty for particle decay.There is no such thing. Energy and time are not complementary observables, so there is no uncertainty relation between them. Indeed...
-
PeterDonis replied to the thread I Need Help on Particle Spin.Except those that don't, such as the Higgs. Unless you're counting spin zero as having "intrinsic spin/angular momentum". Why do you...
-
PeterDonis replied to the thread I Is there a bad intuition or bad explanation in quantum entanglement?.So basically, on the "principle account" view, entanglement in QM is viewed as analogous to, say, relativity of simultaneity, length...

Allori has a nice overview of different types of explanation used in quantum foundations here: https://www.mdpi.com/2624-960X/5/1/7...

Thank you for your helpful comments, as always.

PeterDonis replied to the thread A Dirac's integral for the energy-momentum of the gravitational field.That's true, but it doesn't show that ##M^{\mu \nu}## itself is the intrinsically natural form of that tensor (i.e., the form that...
