Question about QG books---Rovelli's in particular Fra posted this question: Does anyone have an opinion on wether Rovelli's book Quantum Gravity, is best up to date description of the fundamentals of the ideas on which Rovelli builds his LQG? Or should I read something else to complement this? I just ordered his book but haven't received it yet. I'm not sure if there are any revisions, but I think the one I ordered is printed, or reprinted 2005. I'd like to judge for myself his original line of reasoning and wording that leads to this construct. Would anyone recommend something else, to complement such an analysis? I'm not setting out to buy into anything, I rather want to analyse the logic behind his approach, and then I am curious to see if one can generalize the notion of spinnetwork to generic self-preserving information systems. Suggestions? papers? any other books? or is his book sufficient to give a fair representation of the logic of his reasoning (which is really my focus)? Comment would be welcome if anyone has have about using Rovelli's or alternative QG texts, such as Thiemann's.
