Staying Awake.

I'm alternating reading about entropy and Boltzmann's law with Winnie, in order to stay awake. (Winnie wakes me up for Boltzmann, who puts me back asleep.)

Ah, the wisdom of Pooh. First sentence of chapter 1: "Eines Tages, als Pu der Bär nichts anderes zu tun hatte, dachte er, er könnte eigentlich etwas tun..." (Translation: "One day, when Pooh the bear had nothing else to do, he thought, he could actually do something.")

If you don't have anything to do, find something. :)
