an eternal golden braid
Hofstadter's grand epos is full of math, music and other codes, but also full of stories that make a lot of technical details graspable for laymen. I was actually excited about what was told while reading parts of the book. The main topic is self-reference: how it can acome about and what it means if a system (organism or artifact) can refer to itself.
