I loved his "Tatja Grimm's World" for its depiction of a human of "superhuman" intelligence. There's a bit of dialog where the one character tells the other about information theory in a sentence - and the other groks it like Shannon did. In the same genre is "Understand" by Ted Chiang. For me good science fiction (if it's not for the physics or math) is often about the believable alien or superhuman intelligence.
