I honestly don't know what subjects I'm interested in! I wouldn't have originally said "quantum physics," but reading Stephen Hawking was what gave me this idea in the first place, so who knows? I like things that make me say "Wow, REALLY?" Though biography might depress me, reading about too many people who are More Awesome than me-- it depends. If they come by their Awesomeness later in life, maybe. And don't have terribly depressing childhoods.
