In the early 2000s I read The Elegant Universe and I recall it being one of my favorite popular books on physics that I’ve come across. I eagerly awaited this one, and unfortunately it never really resonated with me in terms of the content – it was less revelatory and more contemplative which one usually doesn’t come across in a hard science work. The physics covered is fairly standard for this genre and then you have what seems like a whole chapter on the importance of art. Now, this isn’t necessarily a bad thing, but it’s a bit clumsy here at least in my view. I would definitely pick up a future Greene book but hoping it would be less navel gazing and more on the latest in physics research.
