comment What sort of experiment would directly test time reversal invariance?
If space-time is discrete in ultimate analysis, a violation of Lorentz invariance is not unthinkable. But would this also mean a violation of CPT? Probably depends on the kind of theory.

Thanks, I corrected.

comment Why won't my door close in the winter?
Just checked the climate of Kazan on the wiki page and it is indeed a humid continental climate. I must say though, it's not clear to me if the OP is saying that the door doesn't close because it is too small to fit or too big to fit?

comment How can I stand on the ground? EM or/and Pauli?
Yes, but it's still only the answer to the question of stability of matter, which is only a subproblem within the larger question that the OP asked. I think sigoldberg1 made a good job of analysing the question at a higher level, but it is clear that explaining each step is a huge task in itself.

Right, Mach was indeed the most well-known opponent. I upvoted your answer.

Or in baseball. Even in soccer.

comment Which experiments prove atomic theory?
On the contrary, Boltzmann was an advocate of the atomic hypothesis. He actually implemented it in his mathematical research of the mechanical foundation of thermodynamics. He even introduced quantization of energy before Planck as a tool of computation.

comment Deriving the speed of the propagation of a change in the Electromagnetic Field from Maxwell's Equations
Basically, the form of the equation. As Marek puts it in his answer, it's the d'Alembert wave operator. It's a thoroughly studied operator and the spectrum is well-known. In other words, the behaviour of the solutions is known to be waves moving at velocity the square root of the coefficient in front of the Laplacian (if the coefficient in front of the double time derivative is 1).

Actually, there is an experiment by Perrin related to this which has been pivotal in the acceptance of the atomic hypothesis. I think Perrin got the Nobel Prize for it by the way.

comment Ising model for dummies
Maybe something for Marek, since he's trying to understand the 'Onsager solution' better.

comment CPT and heat equation
@dmckee: Of course, I didn't mean to give an exhaustive explanation. In fact, I left my explanation open to many attacks on purpose. I hope that Boy will think further and come to these questions by himself. But a thorough answer would indeed need a thorough course in statistical mechanics.
