While reading a scientific paper for thermodynamics (Ted Jacobson, Entropy from Carnot to Bekenstein, arXiv:1810.07839 [physics.hist-ph]) I came up to a reference of Boltzmann’s (and later on Planck’s) notion that entropy corresponds to the logarithm of the number of microstates compatible with a macrostate, and that entropy is maximized in equilibrium. Given that, one can…
