And with that, the thread will remain closed. Thanks to all who provided responses.

Yes, you are. You've claimed more than once in this thread that your observations "contradict the textbooks". No, you're not. Claiming...

Excellent. Most of the suggestions you have received can be done with kitchen equipment. This is simply not correct. I have been a peer...

This is no paradox, it is standard experimental science. Well-considered and carefully-executed controls are critical to good...

The volume expansion from water to ice is an intrinsic property of water specifically under the constraint of negligible confining...

These solution wave functions must be zero outside the box. They are not simple sinusoids functions. Their momentum wave functions do...

The wavefunction is zero outside the box, so you don't strictly have two exact but opposite momenta. Also, these two momenta are further...

If you define ##e^x## as the inverse of ##\ln x##, you are making use of the definition of the term "inverse", which says that, given a...

If the "second derivative is (just) enough to detect it" then it means you are measuring curvature. :) The geodesic deviation equation...

This is tidal gravity. It is curved spacetime, not flat. It is physical gravitation and cannot be removed by a change of reference...

But, as has already been pointed out, none of this can be done within a single locally flat patch. You have to look at a region large...

Not for fictitious forces. For non-fictitious forces, it holds even in curved spacetime. But... Nothing to do with tidal gravity...

No, it doesn't; indeed, it's easier in GR, because in GR, "gravity" is a fictitious force! In other words, a "fictitious force" in GR is...

Yes.

In SR, yes. In GR, no--in GR the laws have to look the same in all frames, not just inertial frames.
