Here's a link (http://scienceblogs.com/pharyngula/2007/03/whats_the_matter_with_colorado.php) for further background on the teacher. Utterly amazing.
Also funny, the cover of his book is supposed to depict DNA.
The author discussing the cover art with the artist: I want a close up of DNA on a blue background.
artist: So, a double helix right?
author: No, it's like a ladder, twisted in loops, you obviously haven't had any science classes.
artist: Well, I guess not.
