**Abstract:**
Present-day fundamental physics is a torso: Macroscopic bodies satisfy classical
physics (Cl), non-relativistic (NR) for beta , special-relativistic (SR)
for beta , and general-relativistic (GR) when strong gravity is not excluded.
Submacroscopic bodies - molecules, atoms, nuclei, and all the elementary
particles - satisfy instead the laws of quantum physics (Qu) according to which
their propagation is field-guided. (Qu) applies to a particle iff its (linear)
size s is at most comparable to its de Broglie-Dirac length, . Fundamental
physics can therefore be divided into six categories, labeled respectively
by NR, SR, GR and Cl, Qu. In each of them, both box thermodynamics and
magneto-thermo-hydrodynamical systems of equations can be derived, describing
the system's conservation laws, equations of motion, and growth of (coarse-grained)
entropy. On phase space, the inequivalence of (Cl) and (Qu) can be
traced to the Poisson bracket equalling the Moyal bracket only to first order
in , and to non-local distribution functions. The missing 6th box GR, Qu
coincides with Hasselmann's yet unexplored metron approach.
