Some sadness. The very first words on the back cover of the paperback edition, after PHYSICS, are:

"The Holy Grail of modern physics is the theory of 'quantum gravity'. It is a search for a view of the Universe that unites two seemingly opposed pillars of modern science..." et cetera. Let's unpack these two sentences. The first mentions the Holy Grail, which I think is not the right analogy for a mathematical description of spacetime. I seem to remember the Holy Grail as the one identified by Indiana Jones as the unassuming ceramic cup Jesus drank out of. No disrespect to Jesus, but it's a bummer that Basic Books feels like they need to market Lee Smolin the way they market the Da Vinci Code.

The book itself is delightful. I like this Lee Smolin.

Many worlds, with a hypothetical observer outside them? No, one world, with many observers.

The universe is made of processes, not things.
