I like to think of thermodynamics as an open problem. Consider the
rate of heat propagation in a solid. It is extremely slow. While sound
might travel through a solid rod in a millisecond the heat could take
minutes to propagate. The slowness does not mesh with the
interpretation of heat as vibrating matter. I find little discussion
in this context. I think that as gravity or mass has been redeclared
an open problem so will heat be.

As an antireference I use Kittel's 5th edition of Introduction to
Solid State Physics, where phonon theory is presented. No discussion
in terms of time related behaviors takes place. Heat capacity and
conductivity are studied, a mean free path is discussed, but the
extremely divergent behaviors between mechanical lattice vibrations
and heat in terms of propagation in time are not discussed.

I'm sorry I've not responded very directly to Pentcho's OP, but I do
like where he is going.
Thanks Pentcho.
