czetie: For those that want a lighter version, but still in Deutsch's own words, pick up a copy of the current New Scientist.What makes this exceptionally interesting is that many leading physicists have suspected that information plays a fundamental role (clues include the entropy result for black holes, among others); Deutsch and his collaborator Marletto have done the really hard part of expressing these suspicions in explicit form.It's not unrelated that Deutsch is a proponent of the Many Worlds interpretation of QM, which when properly understood is actually an interpretation about information (not really about branching universes as popularly explained).
BigLuca: Have you read his new-ish book, The Beginning of Infinity? I was thinking of getting it. Seems more philosophy than hard science, but that might be better for the interested amateurs out there like me.
UTD_Elcid: I'm not sure about the information theory parts, but the writer seems weak on the the mathematics of conservation on energy. The conservation of energy principle says that all energy in a close system is a constant. Seem like a "mathematical truth" to me, at least as it relates to the physical world.
RedZoneTuba: To paraphrase Hawkeye Pierce, "Very good, Deutsch, your theory is concise, informative, and makes no sense whatsoever."(Theoretical Physics makes my brain hurt.)
