I see that Lee Smolin has a new book coming out:
Time Reborn: From the Crisis in Physics to the Future of the Universe. I haven't followed physics in recent years as closely as I used to (and may again) but I'm confident this will be a highly interesting book. Smolin is an excellent writer and an intriguing, independent thinker on physics and more. I interviewed him back in 1999 for a
Reason article and
reviewed his book
The Trouble With Physics: The Rise of String Theory, The Fall of a Science, and What Comes Next, also for Reason, in 2007.
