Jonathon, being a huge nerd and a big linguistics guy, are there any examples of linguistics in science fiction that you've really liked?
I recently read "The Story of your Life" by Ted Chiang, which is about a linguist learning the language(s) of aliens that come to earth. I really liked the story, but I wondered if the linguistically competent around here would just roll their eyes at it.
There's also BABEL-17, which relies heavily on the old theory (which I cannot name, but which you should recognize) which says that the way we think is shaped by our language.
