Caltech, String Theory, and Geek References

The show is set in Pasadena, home to the California Institute of Technology. String theory, super-asymmetry, the Expedition 31 mission to the International Space Station, the eventual Nobel Prize: science plays a real role here. Comics, Star Wars, Star Trek, Doctor Who, and Stuart Bloom's comic book store weave through the group's geek culture. Some of the hard questions require knowing about Stephen Hawking's or Wil Wheaton's appearances as themselves.
