  The foundations of statistical physics may today be characterized as a battlefield between a dozen or so different schools, each firmly dug into their own trenches, e.g.: ergodic theory, coarse-graining, the approaches of Markovianism, interventionism, BBKGY, or Jaynes, Prigogine, etc. Still, many of the protagonists of these schools, regardless of their disagreements, frequently express their debt to ideas first formulated to Boltzmann. Even to those who consider the concept of ensembles as the most important tool of statistical physics, and claim Gibbs rather than Boltzmann as their champion, it has been pointed out that Boltzmann introduced ensembles long before Gibbs. And those who advocate Boltzmann while rejecting ergodic theory, may similarly be reminded that the latter theory too originated with Boltzmann himself.
