A review by zachcarter
The Elegant Universe: Superstrings, Hidden Dimensions, and the Quest for the Ultimate Theory by Brian Greene

4.0

After revisiting this ~10 years after I first discovered it, I think my appreciation for and skepticism of it both increased in pace with one another. I think the most compelling and intriguing (to me) unification born of string theory is the black hole/elementary particle connection: as a Calabi-Yau space undergoes a space-tearing conifold transition, a black hole becomes increasingly massless until you get transmutation (a Calabi-Yau phase transition) to a massless photon, which - per string theory - is just a single string vibrating in a fixed pattern! That to me is worthy of the title: Elegant.

As this was written after the relaunching of the second wave of excitement around string theory, you can tell Brian is really trying to sell it. At times, I found it a little annoying, focusing too much on what X or Y physicist has to say about the potential of the theory. Focusing more on the facts, the limitations, the successes, and the failures would have made it a bit more succinct and less of a “promotional” feeling.

But for what we knew in 1999, and looking at how much more we know now, I think this book held a lot of promise and hope for the future of theoretical physics, and works really well as a primer to some more recent scholarly work.
