(And thank you, I'm glad you enjoyed What is Real? so much! I knew this new book wouldn't necessarily appeal to everyone who liked my first one, but I had to follow my heart. And I do think that the style and tone is similarly friendly & fun, even though the subject matter is pretty different.)
Yes, I think it was the similarity in tone and style contrasted so starkly with the different depths of the ideas (I read the first and the second within two weeks) that made it such an 'experience'. Very much enjoyed it, worked as a lovely companion to Lee Smolin's Einstein's Unfinished Rev'n.
