I’m trying something new here, starting with this post: I’m blogging the Feynman Lectures on Physics, chapter-by-chapter (approximately). For those of you unfamiliar with the Feynman Lectures, they’re a classic set of introductory college physics lectures given by the great Richard Feynman 50 years ago at Caltech, compiled into book form. But despite their provenance, the books are not really introductory. They’re more like a rite of passage…Read more "Blogging the Feynman Lectures"
I’ve been out on the East Coast for the last two weeks, and I’m headed back west later today. While I was out here, my friends Yuko and Conrad put me in touch with Rym and Scott, who run GeekNights, and I ended up recording an interview with them. They posted it as a podcast, and you can listen to it here….Read more "GeekNights Interview"
The Second Law of Thermodynamics — entropy never decreases in a closed system — is among the more famous laws of physics. If you’re reading this blog, I’d be surprised if you’ve never heard of entropy before. You’ve probably also heard that entropy has something to do with disorder, and that the Second Law basically says that the universe tends toward disorder, but that’s not quite what the second law says — entropy isn’t really the same thing as disorder, though they’re related.
So what’s entropy? To answer that, I’ll steal a little bit from Kurt Vonnegut…Read more "Entropy and Billy Pilgrim"
