By the way, I never realized that to be nonbelieving, to be an atheist, was a thing to be proud of. It went without saying as it were. - Erwin Schrödinger

Boltzmann’s equation is well illustrated by that example. The gradual ‘spreading out’ of the sugar over all the water available increases the disorder D), and hence (since the logarithm of D increases with D) the entropy.

To the physicist – but only to him – I could hope to make my view clearer by saying: The living organism seems to be a macroscopic system which in part of its behaviour approaches to that purely mechanical (as contrasted with thermodynamical) conduct to which all systems tend, as the temperature approaches the absolute zero and

Even if I should be right in this, I do not know whether my way of approach is really the best and simplest. But, in short, it was mine.
