This is my favorite lecture. It is addressed to anyone who has heard about “entropy of mixing”.
It is more of an “educational”, or pedagogical character, than a research topic. I have given this lecture more than 30 times, all over the world. In most places the audience enjoyed it. And, of course, I have had a lot of fun too. The main idea is that, contrary to what is written in most textbooks, mixing of ideal gases, in itself does not change any thermodynamic property of the system. Hence, thermodynamically speaking, it is a “non-process”. The informational-theoretical aspects of mixing and assimilation is discussed - be ready for some stunning conclusions!
