Trying to calculate proper time of worldlines using rotating frames
.
Ah, yes, that's right. I was implicitly thinking of it that way. Good catch!

Both work, but the double pound signs and dollar signs are definitely easier and quicker to type, and easier to keep track of. :wink:

Question about Parallel Transport
.
Generally yes, since it's generally used in a relativity context along worldlines. However, the definition only makes use of path...

Question about Parallel Transport

While I know what you mean by this, I would point out as a caution that the term "geodesic deviation", at least in a GR context means...

Your ##d \phi d t## cross term isn't quite right; the factor in front should be ##2 \omega r##, not ##2 \omega r^2##. (When doing these...

You had two bugs, opening "itex" tags and closing "tex" tags. I just used magic moderator powers to fix both of them. Your equations...

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...

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...

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...

Yes, and the heat equation is not a wave equation. So this... ...doesn't seem right.

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...

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...

It might be because the MWI is the predominant no collapse interpretation, and since every attempt to try to pin down collapse as an...

I didn't say the definition of parallel transport assumed geodesics. My concern was the difference between parallel transport and...
