Dale replied to the thread I Intrinsic curvature.Why would you do it without recourse to parallel transport? -
Dale reacted to pervect's post in the thread I Synchronizing clocks in an inertial frame if light is anisotropic with
Like.
Yes, I personally think it would be simpler to introduce relativity by means of proper velocity, or as you write it ##dx/d\tau##. Do... -
Dale reacted to Ibix's post in the thread I Synchronizing clocks in an inertial frame if light is anisotropic with Like.
I also agree. To call what you get with a homogenous but anisotropic two way speed a "simultaneity plane" you need to require that...

Dale replied to the thread I Synchronizing clocks in an inertial frame if light is anisotropic.There is disagreement in the literature on this point. But I tend to agree with you. Anderson, in contrast, does not restrict his...

Dale reacted to PAllen's post in the thread I Synchronizing clocks in an inertial frame if light is anisotropic with Like.
I would think of that more like the case of lightlike coordinates. That a time coordinate is the same along a null path in some...

Dale replied to the thread I Is Maxwell's electromagnetism an effective (field) theory?.Unfortunately, that means the topic is not suitable for this forum. We exclusively focus on topics that are in the literature. We could...

Dale replied to the thread I Is Maxwell's electromagnetism an effective (field) theory?.I see where you are coming from, but I think that usually EFT's are considered in the context of renormalization groups etc. I don't...

Hello fellow Physics enthusiasts, I am an aeronautical engineering graduate (Bachelor's) who is interested in Physics and Mathematics...

The Levi-Civita connection is the unique metric compatible and torsion free connection on a Riemannian manifold (or pseudo-Riemannian)...

Parallel transport is perfectly well defined along non-geodesic curves. The manifold described in the video is a Riemannian manifold so...

It depends on what "in the same direction" means. Parallel transport is one way of defining what "in the same direction" means...

Dale reacted to Herman Trivilino's post in the thread I To predict the nature of Normal Reaction in any mechanics set-up with Like.
I realize that this is probably tangential, but the so-called normal force is actually the perpendicular component of the contact force...

Every time he himself turns by an angle x relative to the ground beneath his feet, he also turns the arrow by -x relative to himself, so...

Dale replied to the thread I Synchronizing clocks in an inertial frame if light is anisotropic.@James Hasty has prepared the diagram and some careful thoughts so I am reopening the thread.

Dale replied to the thread B Fundamental Probability.Why would it? Which specific step of the scientific method do you think is invalidated in a probabilistic universe?
