It's 2001 now... so all the mathmaticians can now just shut up already! :]
I spent the New Year's holiday with family in Vermont. My dad cracked me up: he read an article in the local paper, then asked me if I'd ever heard of Arthur C. Clarke.
Considering I've been a lifelong science fiction reader, that was a bit like asking a mountain climber if they've ever heard of Everest.
