Closing tabs

A conversation with Randall Munroe, including a fascinating description of the origin of the What If? series (via GeekPress):
It actually started with a class. MIT has a weekend program where volunteers can teach classes to groups of high school students on any subject you want. I had a friend who was doing it, and it sounded really cool -- so I signed up to teach a class about energy, which I always thought was interesting, but which is a slippery idea to define. I was really getting into the nuts and bolts of what energy is, and it was a lot of fun -- but when I started to get into the normal lecture part of the class, it felt kind of dry, and I could tell the kids weren't super into it. And then we got to a part where I brought up an example -- I think it was Yoda in Star Wars. And they got really excited about that. And then they started throwing out more questions about different movies -- like, "When the Eye of Sauron exploded at the end of The Lord of the Rings, and knocked people over from this far away, can we tell how big a blast that was?" They got really excited about that -- and I had a lot more fun doing it than I did just teaching the regular material.
So I spent the second half of the class just solving problems like that in front of them. And then I was like, "That was really fun. I want to keep doing it."
