for anyone interested in string theory, Lee Smolin just wrote an interesting critique of it: The Trouble With Physics. amazon.com basically, Smolin argues that a lot of string theory is ad hoc and not really science. Heinz said there were "several" string theories. in fact there are hundreds of thousands, maybe millions, of theories. string theory relies on Calabi-Yau manifolds, and Yau himself estimated their number at more than 100,000. Smolin critiques the ad hoc and arbitrary manner in which parameters are assigned values (set them to match the data, as opposed to coming up with a theory that predict what the data will be like Einstin did with Special Relativity). science has advanced over the centuries through establishing falsifiable hypotheses which make predictions about the world, then conducting experiments to see if the predictions come true. that's not what string theory does. Smolin also criticizes modern academic theoretical physics for what he sees as a conformist, groupthink approach. another book criticizing string theory humorously sums it up in its title: Not Even Wrong amazon.com
