Probably known to most people, but "Guns, Germs, and Steel" by Jared Diamond turned me on to a lot of things. The work covers many topics, including history, geography, evolution, giving a very wide view, which serves as a good starting point to start exploring some of these topics deeper.

Ages ago, "Gödel, Escher, and Bach" turned me from a kid who liked computers into someone very into music, math, philosophy, and literature. It does a great job of showing the reader the joy of playing with abstract concepts across several fields, including writing.
