comment At the atomic level, is heat conduction simply radiation?
Conventional understandings are challenged only when the question demands so (if it is at the boundary of physics). For the scope of @Alraxite's question, the standard definition of atom suffices. Using "ultimately we don't know the answer" for every question is too overkill.

comment quantum explanation of doppler effect
hi @Ron in your answer physics.stackexchange.com/a/29361/1814 . "Galilean invariance of the Schrodinger equation: this part is not done in any book, I think only because Dirac omitted it from his. It is essential to know how to boost wavefunctions. Since Feynman derives the Szchrodinger equation from a tight-binding model (a lattice approximation), the Galilean invariance is not obvious at all." -> I think you need to add the fact that specifically, we are doing a lorentz boost to the canonical momentum in the wavefubction?
