Time Reborn
From the Crisis in Physics to the Future of the Universe
Lee Smolin
read on August 1, 2013

I need to revisit this book again later. I didn't have the time, focus, or energy to do it justice. The central idea is that time is the only immutable, constant force in the universe. Time moves in one direction, and has a beginning and an end, and every single other thing varies; e.g., all the "constants" of physics are not constant at all.

Everything about this book should appeal to me, but none of it did. I think it was over my head, and I got rather bored with it. I'm really not sure what the problem was, but it was pretty disappointing. I'm not ready to say it's a bad book - I don't think it is, but I couldn't really recommend it, yet. I'll give it another shot someday when I'm ready to take it more seriously.

Author Bio:

Lee Smolin (born June 6, 1955) is an American theoretical physicist, a faculty member at the Perimeter Institute for Theoretical Physics, an adjunct professor of physics at the University of Waterloo and a member of the graduate faculty of the philosophy department at the University of Toronto. Smolin is best known for his contributions to quantum gravity theory, in particular the approach known as loop quantum gravity. He advocates that the two primary approaches to quantum gravity, loop quantum gravity and string theory, can be reconciled as different aspects of the same underlying theory. His research interests also include cosmology, elementary particle theory, the foundations of quantum mechanics, and theoretical biology.
