Oh no. Damn. I was always hoping I'd get him to autograph something for me. :(

Seems to go back to a FB posting. I'd be more skeptical, but the guy was 97.

Okay, well, I sincerely hope the poster got it wrong. Smullyan's retrograde analysis books got me into logic.

One of my heroes. Though I never had much of a head for logic.

Haha, well, I read your tweets and I sincerely doubt that. Here's to hoping Smullyan hasn't gone to Valhalla just yet!

I'm good at, roughly, the semantic side of math--visualization/process/structure. I suck at syntactic manipulation.

I can do the early puzzles easily but when he really gets the machinery going my eyes glaze over.
