Entropy freaks me out. Infinity fascinates me. I can look at an asymptotic mathematical equation and feel vaguely uneasy. But the funny thing is--those things scare me, but they intrigue me at the same time. I knew how black holes worked when I was ten years old; I even taught myself about what equations were so I could work out the equations I read about in books about them. Black holes are beautiful, bizarre, fascinating, frightening; they follow from the laws of physics, and then break those same laws... they are the closest thing in the real world to a cosmic Cthulhu.
