I spent a long weekend in Whitby recently and I recommend it. Over the weekend the name Penrose came up again and again. I had packed Roger Penrose's "The Emperor's New Mind" in another forlorn attempt to finish the book. I needn't have worried. As I sat at dinner at the wonderful Magpie Café, a young bearded Englishman at another table explained the entire thesis enthusiastically to a young bearded Frenchman. My eagerness to overhear this conversation meant that I missed some of my hostess' remarks about...yes...Penrose, but I discovered she meant the English Surrealist painter and poet Roland Penrose. A visit to the Whitby bookshop yielded science fiction I hadn't read before, "White Mars" by Brian Aldiss and...sorry, you guessed...Roger Penrose.
