Unfortunately, that means the topic is not suitable for this forum. We exclusively focus on topics that are in the literature. We could...

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...

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...

@James Hasty has prepared the diagram and some careful thoughts so I am reopening the thread.

Why would it? Which specific step of the scientific method do you think is invalidated in a probabilistic universe?

According to our best current theoretical models, they're quantum fields. Yes. This is much too vague. We can't give you a course in...

Yes. That is why I said “moving normal relative to the surface”.

It doesn’t matter if it is small or large. What matters is the direction. If the charge is moving normal relative to the surface then...

Not necessarily. As I said above, surface charge is not intrinsically tied to the bulk charge, but you could get a surface charge...

Yes. That is what I am saying. This is an example of a scenario where there is not a surface charge.
