The Elegant Universe (book)
Brian Greene The Elegant Universe (1999). About string theory, Excellent overview of Newton --> Einstein --> Planck, and summary of problems with the Standard Model: the incongruity between general relativity and quantum theory. Although Greene goes to great lengths to stress what isn't known, he more than half convinces me that string theory (or one of them, anyhow) is right. For one thing, he explains the hidden dimensions so well. However, absent experimental data, and absent any near future likelihood of getting any, the whole thing is beginning to look suspiciously like medieval scholasticism: spinning elegant and consistent theories about matters that can't be observed. Except of course that in principle string theory is experimentally confirmable, unlike theories about angels.... Oh well, it's fun, and it suggests all sorts of SF story ideas. *** (1999)
