Oh! I've been meaning to check out this book after reading his essay in another book (Curious Minds) about scientists explaining how they became, um, scientists.
Anyway, thanks for the reminder about Phantoms. There's also a series of lectures he did for the BBC that I've been meaning to listen to, if you haven't already heard them, though there's probably repetition/overlap. Here's the link anyway: http://www.bbc.co.uk/radio4/reith2003/lecturer.shtml
