I listened to the author of this new book this morning, along the lines of The Physics of Star Trek and a few others.
The author is an actual physics teacher, and has fun using the series to explain some concepts.

Along the same line, in the popular "..... and Philosophy" series, we have "Fear and Loathing in Sunnydale:
Amazon.com: Buffy the Vampire Slayer and Philosophy: Fear and Trembling in Sunnydale (Popular Culture and Philosophy): Books: James B. South,William Irwin
Both should be fun reads.
