And so, a model (motivated by physically observed phenomena) and a set of tools to analyze the model lead to testable predictions, which...

Because the light moves at ##c## with respect to any inertial observer.

I'm not sure what you mean. Surely the pulse is always moving from one part of the apparatus to another? You certainly can consider a...

I wouldn’t read that into the question. This question can be answered in GR (as I did above) even though GR is non-Machian

Geometrically it is for the same reason that an angle requires two straight lines but a curved line can make definite angles with...

Centrifugal forces cannot be experienced. They produce no measurable effect. They are only mathematically inferred due to motion.

Hi. I’m studying GR on my own. Perhaps we could talk privately? I’ll sent you a DM.

It is not generally true that the E field in a conductor is 0. It is only true in the electrostatic limit where the current density is zero.

There has been an influx of math and physics people into a number of biological sub-fields. Areas like genetics (like Watson and Crick...

I guess I took the diagram too literally then. In this case I agree with @Dale that the mechanism proposed by @jbriggs444 is quite...

I'm really glad you posted this and shared the quote from @jbriggs444. I did read his post, but maybe, since I was reading a lot of...

This sounds like the most likely hypothesis. It could be tested by comparing a bag with trapped air and a bag with all air removed. It...

Here is some of a special issue of Genetics of articles using math: Many of the articles are open access. They can be seen here...

Investigating the history of math or the philosophy of math is not exactly the same as using math. A more convincing reference would...

The idea is that with water on all sides, the clay is effectively sealed. Any air in the lump of clay cannot escape without forming a...
