Ppervect replied to the thread Undergrad Question about Parallel Transport.A limited notion of parallel transport that works on a sphere is, IMO, a good place to start. One start with the notion that great...
-
Ppervect replied to the thread Undergrad Can a Gyroscope in a Satellite Detect Orbit?.Thanks - I can see why if the majority of the effect is due to "the missing inch" aka "space curvature", one might neglect Thomas...

Like.
When you scroll down on this page: https://archive.org/details/L.EpsteinRelativityVisualizedelemTxt1994Insight/mode/2up You will find... -
PI can’t seem to let this go, partly because some have asked for how to make the embedding result (part of Euclidean plane in 3-sphere)...
-
Ppervect replied to the thread Undergrad Can a Gyroscope in a Satellite Detect Orbit?.Section 7 of the reference I quoted explains this in more detail: So yes I agree that Thomas precession is just one component of the...
-
Ppervect replied to the thread Undergrad Can a Gyroscope in a Satellite Detect Orbit?.I agree with your no answer to the OP's question, but you haven't mentioned Thomas precession at all. The best reference I have at the...
-
Ppervect replied to the thread Undergrad Can a Gyroscope in a Satellite Detect Orbit?.As far as I know, this is just due to the ISS being deliberately locked to a constant orientation relative to the Earth, for practical...
-
Ppervect replied to the thread Undergrad Is this another "paradox" or a veritasium mistake?.Yes, I was in a bit of a rush - though I probably couldn't be that precise anymore anyways. (Was I ever? Probably not, not that it...

Ppervect replied to the thread Undergrad Is this another "paradox" or a veritasium mistake?.It would be bent twice as much by a mass. But I don't think not on an elevator. I don't have a reference for this statement, but I...
-
Ppervect replied to the thread Undergrad Can a Gyroscope in a Satellite Detect Orbit?.There's a couple of different questions here. Basically, using devices that spin (such as the Forward Mass detector), can detect...
-
Ppervect replied to the thread Undergrad Euclidean geometry and gravity.Thank you. Untangling this in terms I can more fully understand will be quite a problem. I'm suspecting the issue is fundamental in...

Ppervect replied to the thread Undergrad Euclidean geometry and gravity.Two dimensional
-
Ppervect replied to the thread High School Train Fall Paradox.Not a paradox, but a rather hard problem. To deal with the problem with special relativity, I'd suggest replacing gravity due to mass...

-
Ppervect replied to the thread Undergrad Euclidean geometry and gravity.Sorry for this very late response. My first thought was that you had a good point, but as I was thinking about this more later, and I...

Ppervect replied to the thread Undergrad Euclidean geometry and gravity.I've been assuming the answer to this question is, informally, "the shortest path". The mathematical term is the "Levi-Civita...
