Earlier this month I posted about *Quantum Reality* (2020), Jim Baggott’s recent book about quantum realism. Now I’ve finished another book with a very similar focus, ** Einstein’s Unfinished Revolution: The Search for What Lies Beyond the Quantum** (2019), by

**Lee Smolin**.

One difference between the books is that Smolin is a working theorist, so he offers his own realist theory. As with his theory of cosmic selection via black holes (see his 1997 book, *The Life of the Cosmos*), I’m not terribly persuaded by his theory of “nads” (named after Leibniz’s monads). I do appreciate that Smolin himself sees the theory as a bit of a wild guess.

There were also some apparent errors that raised my eyebrows.
