  The problems with an emergent approach to quantum statistical mechanics are
discussed and shown to follow from some of the same sources as those of quantum
measurement. A wavefunction of an N atom solid is described in the ground and
excited eigenstates with explicit modifications for phonons. Using the
particular subclass of wavefunctions that can correspond to classical solids we
investigate the localization properties of atomic centers of mass motion and
contrast it with more general linear combinations of phonon states. The
effectively large mass of longer modes means that localization present in the
ground state persists on excitation of the material by macroscopic coherent
disturbances. The "thermalization" that arises then follows from the long term
well defined motion of these localized peaks in their 3N dimensional harmonic
wells in the same fashion as that of a classical solid in phase space. Thermal
production of photons then create an internal radiation field and provides the
first dynamical derivation of the Planck distribution from material motions.
Significantly, this approach resolves a long standing paradox of thermalization
of many body quantum systems from Schr\"{o}dinger dynamics alone.
