I gave a talk yesterday at the Center for Inquiry branch here in LA. It was a popular-level spiel on The Origin of the Universe and the Arrow of Time; click for slides. If I had been thinking, I would have advertised the existence of the talk before I had given it, rather than afterward. Either that, or I was trying to smoke out time-travelers.


But the real reason I'm even bringing it up is to give credit to this great YouTube video, found via Swans on Tea. I was literally zipping through blogs yesterday morning while drinking coffee and preparing for the upcoming talk, when up popped this wonderful illustration of entropy and the arrow of time, which naturally I showed at the talk. And it features a kitty. (Schrodinger has his own cat, why shouldn't Boltzmann?)
