Abstract

WHEN the collisions between the molecules of an ideal gas are taken into consideration, then the motion of the gas does not appear to be multiply periodic. It is therefore impossible to quantise this motion by means of the classical quantum theory. Moreover, in the treatment of the ideal gas by means of the new undulatory mechanics, hitherto only the impenetrability of the walls of the vessel has been taken into account, and not the reciprocal impenetrability of the molecules (E. Schrödinger, Phys. Zs., 27, 95, 1926). I propose to show here that, in the case of impenetrable moving mass-points, wavemechanics gives an exact and very elementary solution. Simultaneously we arrive at the relation mentioned in the title.
