Shiloh, Mercina and I got back to New Haven today. Even though school doesn't start until Monday, I decided to start the semester off right by doing some larnin on the Youtube. If you're looking for a good time, watch this video of Richard Feynman discoursing on, among other things, how fire is recycled sunshine and trees assemble themselves from thin air. But "how is it the tree is so smaht?" Wonder no longer -- Richard Feynman will tell you.
