The previous talk in the series is here. The next talk in the series is here.
This is an introduction to the concept of entropy (in the information-theoretic sense of the word). In the next few talks I shall say more about the concept and give a few non-obvious applications of entropy to combinatorial problems. We give the entropy axioms, then see a few simple consequences of the axioms.
