A quick note: This week, the BBC posted the second of Stephen Hawking's Reith Lectures focusing on Black Holes. And, once again, they've animated the presentation with some fun chalkboard illustrations. You can watch Part 1, “Do Black Holes Have No Hair?” here. And now Part 2, "Black Holes Ain't as Black as They Are Painted," above. Hawking is getting a little playful with his grammar, isn't he? Enjoy.
