 I got this note from Ted recently: "After my coding talks in the fall, several people asked me if I had seen the PBS show on codes produced by Singh, the guy who wrote "The proof" about Wiles solution of Fermat's last theorem. I hadn't. Just before Christmas Anne and I were in a book store and I saw the book based on the show called "the code book". She got it for me. I read it and it is GREAT. If you have any interest in codes at all, or know students who are, I recommend it."
