JJames Hasty replied to the thread I Synchronizing clocks in an inertial frame if light is anisotropic.I agree this works, but only because you have defined the convention for the 1-way speed of light in both directions.

Just to clarify the point, I drew the following diagram. The base grid ##(x,t)## represents of course the standard inertial coordinate... -

That is good work. It is much more difficult to do than it appears at first glance. -

Yes, as far as I can tell the key point is that basically, before the exchange of light signals between observer A and B takes place, it... -
JJames Hasty replied to the thread I Synchronizing clocks in an inertial frame if light is anisotropic.The purpose of my post was to demonstrate a way to synchronize two clocks located in the same inertial frame. I thought this would be...

Indeed, if I am reading my notebook correctly the Lagrangian for a free particle in an Anderson synchronized frame is $$L=-(\dot... -

I'd like to expand on my earlier point. Suppose we have some frame in which Newton's laws work. Two equal masses moving in opposite... -

As long as you don't believe that your clock synchronization has any physical significance, in particular as long as you don't address... -

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...

Like.
This must be true, because the definition of such coordinates is based on the Einstein clock synchronization, that means on the...
