I'M OFF to the Edinburgh book festival. No time for blogging this morning. I'll try to fit some in this evening.

UPDATE (7:45 pm): We heard a very good lecture by Cambridge astrophysicist John D. Barrow on the history of Cosmic Imagery. But the venue was disappointing. The tent where the lecture was held was suffocatingly hot and all the doors were kept closed (to keep noise out?). I've not been to the book festival before, but I would have expected better planning. Oh, and we bought some books too.
