PeterDonis replied to the thread B Trying to calculate proper time of worldlines using rotating frames.You had two bugs, opening "itex" tags and closing "tex" tags. I just used magic moderator powers to fix both of them. Your equations... -
PeterDonis replied to the thread I Schrödinger equation and classical wave equation.But you admit later on in your post that both of these things can also be true of a classical equation. So they don't explicitly tell...
-
PeterDonis replied to the thread I Schrödinger equation and classical wave equation.I don't see a contradiction. A mathematical equation, in and of itself, doesn't tell you how to interpret it physically. You always have...

PeterDonis replied to the thread I Question about discussions around quantum interpretations.My favorite quote from that essay: "If you have bought one of those T-shirts with Maxwell's equations on the front, you may have to...
-
PeterDonis replied to the thread I Schrödinger equation and classical wave equation.Yes, and the heat equation is not a wave equation. So this... ...doesn't seem right.

PeterDonis replied to the thread I Question about discussions around quantum interpretations.Note that, while, as I said in my previous post just now, the MWI doesn't work this way, the Bohmian interpretation, which is also...
-
PeterDonis replied to the thread I Question about discussions around quantum interpretations.No. That's not how the MWI works. In the MWI, all possible outcomes occur, each in its own branch of the wave function. It's not even...

PeterDonis replied to the thread I Question about discussions around quantum interpretations.Not that I'm aware of.
-
PeterDonis replied to the thread I Question about discussions around quantum interpretations.It might be because the MWI is the predominant no collapse interpretation, and since every attempt to try to pin down collapse as an...
-
PeterDonis replied to the thread I Question about Parallel Transport.I didn't say the definition of parallel transport assumed geodesics. My concern was the difference between parallel transport and...
-
PeterDonis replied to the thread I Question about Parallel Transport.I know it's well defined, I'm just not sure it's what the OP intended by "the same direction" along a non-geodesic curve. I wasn't...
-
PeterDonis replied to the thread I Question about Parallel Transport.It depends on what "in the same direction" means. Parallel transport is one way of defining what "in the same direction" means...
-
PeterDonis replied to the thread A Collapse of wave function and consciousness.The OP refers to: Those are ways of describing the "consciousness causes collapse" interpretation of QM. The OP might not have...
-
PeterDonis replied to the thread A Collapse of wave function and consciousness.But we don't know that consciousness is a "basic element of Physics". Chalmers might think it is (although at different times he says...

PeterDonis replied to the thread B Matter density right after the decoupling.Yes. Because plasma doesn't work like air. Even at such extremely low density, it interacts strongly with light.
