Like.
Indeed, to be clear post a spacetime diagram with each event labeled and each signal indicated. And perform your calculations using one... -
JJames Hasty replied to the thread I Synchronizing clocks in an inertial frame if light is anisotropic.Let's be clear on definitions: The 2WSOL can be calculated by timing a reflected light beam using 1 clock. For example: A sends a signal...

JJames Hasty replied to the thread I Synchronizing clocks in an inertial frame if light is anisotropic.An observer can only know that if the 1WSOL is isotropic. I am assuming it is not.

JJames Hasty replied to the thread I Synchronizing clocks in an inertial frame if light is anisotropic.That is for the 2WSOL (2-way round trip of light), which is a given because it is true. I am assuming the 1WSOL is anisotropic.

JJames Hasty replied to the thread I Synchronizing clocks in an inertial frame if light is anisotropic.In the introduction, "it is given" that the average speed of light is c for the 2WSOL . Then t[B2] - t[B1] = 2L/c.

JJames Hasty posted the thread I Synchronizing clocks in an inertial frame if light is anisotropic in Special and General Relativity.ASSUMPTIONS 1. Two identical clocks A and B in the same inertial frame are stationary relative to each other a fixed distance L apart...

JJames Hasty reacted to Sagittarius A-Star's post in the thread I Why measure the speed of light in one direction? with Like.
This must be true, because the definition of such coordinates is based on the Einstein clock synchronization, that means on the...

JJames Hasty reacted to Sagittarius A-Star's post in the thread I Why measure the speed of light in one direction? with Like.
That's not completely correct. Before Einstein, when the physically relevant coordinate transformation was thought to be the GT...

JJames Hasty reacted to Ibix's post in the thread I Why measure the speed of light in one direction? with Like.
You can construct Maxwell's equations in non-orthogonal coordinates if you like. Then you'll get a non-isotropic speed. As always, this...

JJames Hasty reacted to Herman Trivilino's post in the thread I Why measure the speed of light in one direction? with Like.
Not without experimental verification. Because it wouldn't provide that verification.
-
JJames Hasty replied to the thread I Why measure the speed of light in one direction?.My viewpoint is that for all inertial observers with Minkowski coordinates, Maxwell's equations posit the speed of light to be...

JJames Hasty reacted to Sagittarius A-Star's post in the thread I Why measure the speed of light in one direction? with Like.
You could write Maxwell's equations in the following primed coordinates (given any inertial coordinate system x,y,z,t). $$x' = x \ \ \ \...

JJames Hasty reacted to Dale's post in the thread I Why measure the speed of light in one direction? with Like.
In general, you like to try to validate your theories against experiment. However, in this case the one way speed of light is a...

JJames Hasty posted the thread I Why measure the speed of light in one direction? in Electromagnetism.It may be shown from the equations of electromagnetism, by James Clerk Maxwell in the 1860’s, that the speed of light in the vacuum of...

JIt is worth noting that in some specific cases the two family of "slanted" grid lines drawn in the diagram may result as orthogonal...
