I've just finished up Lee Smolin's second book Three Roads to Quantum Gravity and am about 1/3 through his latest book The Trouble with Physics. While doing a bit of side research on Smolin's thoughts, I ran across an interesting NPR discussion from 2006 where Smolin and string theorist Brian Greene discussed modern physics. You can have a listen here: Physicists Debate the Merits of String Theory.
