Summary
DescriptionErgodic hypothesis w reflecting rays.jpg
English: Rays bounding off a truly smooth surface (a) do not satisfy the ergodic hypotheses, as one would expect of rays under the ergodic hypothesis (b). The impossibility of creating a 'tunnel' that uses reflections to create an imbalance in the particle density between (c) and (d) is a cornerstone of classical thermodynamics.
