Taking a small break from versification this week, and have been completely absorbed by The Physics of Superheroes by James Kakalios. It's a physics text of sorts, in that the science is solid and thoroughly explained, but it's also documentation of a love affair with comics. It asks and answers the question "Could this happen?" about many comics from the Golden and Silver eras, with examples of plausible and, well, miraculous physical happenings depicted in those glorious 4-color pages.
I'm not a huge comics fan (though I do enjoy a good Iron Man from time to time), but the enthusiasm Professor Kakalios shows for both his heroes and his equations is enough to carry me - and you - through his 400 pages quickly. He's an eloquent and talented writer.
And yes, I am a geek.
