Dale reacted to Greg Bernhardt's post in the thread Site Usability nitpick -- Hyperlinks should be underlined with
Like.
I have no argument against this. I'll schedule some time to look at this. -
Dale replied to the thread Site Usability nitpick -- Hyperlinks should be underlined.No worries, Greg should weigh in because he is the one who can fix it if needed.

Dale replied to the thread Site Usability nitpick -- Hyperlinks should be underlined.@Greg Bernhardt I agree with @DaveC426913 that your color scheme should be made accessible, if it is not already. I am not sure the...

Contrast between body and link text would pass against a white background but it fails against PF's light grey background...

Dale replied to the thread Site Usability nitpick -- Hyperlinks should be underlined.It appears to me that they are currently distinguished by both color and brightness, as per G183. @Greg Bernhardt can you tell us what...

I'd add the qualifier coordinate speed in both SR and GR is invariant in inertial frames since the 4-velocity of light, like any...
-
Dale replied to the thread A 1-Way Speed of Light.As both @Ibix and @PeroK said, the difference between SR and GR in this respect is that speed can only be compared locally. In both SR...
-
The two way speed of light is only guaranteed to be invariant for inertial observers. Your apparatus is not inertial. The difference...

General Relativity entails general curved geometries, but locally the geometry is Minkowski - technically, it's a Minkowski tangent...

Dale replied to the thread A 1-Way Speed of Light.And its value is independent of R. It does not become small for large R

Dale reacted to Demystifier's post in the thread I Transformation for Lemaitre coordinates with Like.
More generally, for two system of coordinates ##x## and ##y##, one has ##x^{\mu}=f^{\mu}(y)##, so $$dx^{\mu}=f^{\mu}_{,\nu}(y)dy^{\nu}$$...

Dale reacted to FactChecker's post in the thread I Understanding the historical shift away from absolute simultaneity with Like.
In general, you should separate the goals of clear understanding of physics versus knowing the history. There were many confused people...

Clock synchronization is inherent in any experiment to measure the one-way speed of light, which is the very title of this thread. So...

In my opinion arguments over or about the one way speed of light are pretty much a dead end, but rereading the post I see Peter was...
