The second law of thermodynamics is not a council of despair

"What the second law of thermodynamics states, roughly speaking, is that 'things' are getting more random all the time.


The relentless march of randomness
So if we set up a particular situation and then let the dynamics evolve it into the future, the system will evolve into a more random state as time progresses. We must expect that according to the second law things are getting progressively more and more random, but this represents an overwhelming probability, not quite an absolute certainty.


Nevertheless we can state we can state with a considerable amount of confidence that we shall experiene an entropy increase - in other words an increase in randomness."
