In 9.3, page 255, I say that we were in Marrakesh watch the Nobel announcement on 8 November. This was of course 8 October. On the plus side I am grateful to Peter Higgs and Peter Jenni for pointing this out to me – it is an honour to have such distinguished readers. I have no idea why I got this wrong; quite apart from knowning the Nobel date rather well (and writing about it on the same day!), it was a memorable trip to Marrakesh all in all. Here are some photos to prove it.
