Query: On the practical application of negentropic polarization of
  thermodynamically equilibrium photon gas   In the course of the analysis of the axiomatic principles underlying
statistical physics, the assumption about the limited correctness of the
postulate of equiprobability of all available microstates of a closed system
was tested. Earlier, the result of simulation modeling of the most probable
stationary state of a stochastic isolated system, inside which isotropic
monochrome radiation spontaneously acquired anisotropic polarization, was
obtained (later the presence of such an effect was confirmed by a natural
experiment). This article considers an already practically significant variant
of suchlike a system. The conditions for the appearance of polarization
anisotropy in a thermodynamically equilibrium medium initially filled with
isotropic Planck radiation are predicted. Important consistent pattern of the
applied mathematical model are noted.
