Query: An Survey of Computer Science Presented by One of the Field's Finest

Reading this book helped me to remember why I got into computer science in the first place: it's a whole lot of fun. As Alan Perlis admonished us, we musn't ever lose that.All of Don Knuth's books express how fun computer science is, but this one does it in a smallish paperback form with content that's easier to digest as bedside or subway reading than some of his other more famous volumes.
