Gödel, Escher, Bach: An Eternal Golden Braid
Douglas Hofstadter
Douglas Hofstadter
For a classic book dealing with “big” topics like math, music, and philosophy, it’s surprisingly accessible because Hofstadter is able explain complex things in the simplest way possible, which is a hallmark of great writing (not to mention great intellect).
My aptitude in math is slightly above average at best (and way below among my fellow geeks, who tend to be good at stuff like that), so I think you’ll be fine when you do decide to crack it open.
