Three Roads to Quantum Gravity
2 journalers for this copy...
Using these starting points, Smolin gives an overview of what we've learned that can help formulate quantum gravity theories or help disprove those that are wrong. The resulting theories that are not obviously wrong are loop quantum theory and string theory.
Smolin does a fair job explaining them to a scietifically-aware audience (I know a thing or two about physics, so I can't speak to how well he does for a completely general audience). It's not a bad book, though I can't help but wonder if it will horribily outdated in a few years. (Of course, it may take longer than that to develop experiments capable of testing these theories.)
I also was happily surprised about the idea of a traveling book.
I found this one outside Ballroom B on May 31 2005 at the Minneapolis Convention Center at the American Astronomical Society meeting in Minneapolis. I first go read it more carefully, take it with me to the Netherlands and will find a good place to release it again.
