That is also how they measure the two-way speed of light. They ignore any acceleration and therefore assume orthogonal axes. If they do it for the two-way speed of light, it should be done the same for the one-way speed of light.

I said synchronization is impossible using two clocks. That does not imply it is impossible using one clock.

Fizeau's experiment is about a moving medium. The medium does not move in the above. Not relevant.

No, you're assume that the one-way speed of light cannot be measured without two clocks.

If Snell's law wasn't isotropic, then all the optics in the world would need constant adjustment as the world spins around. Since this is not necessary, Snell's law is isotropic.

Your example has two clocks. The above experiment has only one clock. The Wikipedia page discusses the problem of synchronizing two clocks. Not a problem here since there is only one clock.

Snell's law measures if it is isotropic.

Snell's law states that the refractive index is isotropic.

Snell's law states that it is a percentage.

There is only one clock in the experiment.

By using Snell's law, this possibility is removed.

Most physics is described using orthogonal axes. You still haven't specified what is wrong.

True, the one-way speed of light cannot be measured with two clocks. The above experiment uses only one clock.

Physics is not about choice. It's about measurements. Your comment is unclear. Please specify which measurements you think are wrong.

To measure the two-way speed of light, a pulse of light is sent thru a vacuum to bounce off a mirror and return. By knowing the distance to the mirror and how long the pulse takes to travel, the two-way speed of light can be calculated. To measure the one-way speed of light, place a transparent...
