Whoops; sorry, I forgot this comment was here! Hint: it was Anathem. (I thought it was really good -- my favourite of his that I've read, although since upon reflection I realise that I've only read Cryptonomicon and like the first fifty pages of The Diamond Age, that's not as impressive as it might be. It required a lot of science fictional interpolative work but played fair about it and rewarded it, at least in my case, with a lot of delight.)
