BTRIPP's review of Charles Seife's "Decoding the Universe: How the New Science of Information Is Explaining Everything in the Cosmos, from Our Brains to Black Holes" (909 words) This is some extraordinary science writing explaining the effort to recast modern physics as information science. Seife does a marvelous job of explaining some mind-bending concepts. Seife has you from hello: the first line of his book is: "Civilization is doomed." His witty quotes and epigrams at the start of each chapter such as this limerick from A.H. Reginald Buller help sum up the themes of this book: "There was a young lady named Bright, Whose speed was far faster than light; She set out one day, In a relative way, And returned on the previous night." Would this be possible? Seife provides user-friendly explanations of some of the basic theories of physics, including entropy, light speed, quantum entanglement, complementary particles, uncertainty, decoherence, and black holes, all from the perspective of information theory. Information theory, he claims is "the third great revolution of twentieth-century physics." The laws of thermodynamics, relativity, and quantum theory, are all actually theories of information, and Seife explains why this is so. He answers the question of whether a tree still falls in the forest if no one is able to hear it (yes, he says) and reviews theories of how "spooky action at a distance" could make sense. He even gives a reasonable rationale for multiple-universe theories, explaining that if "stars and galaxies and creatures are cut off from us by some sort of barrier that blocks information" they will, in essence, be inhabiting a "different" universe. (i.e., the problem lies more in our traditional conception of "universe" than with the physical possibilities.) His explanations, which often include helpful illustrations, are couched in examples and analogies that will benefit the physics novice, but with the added connection of information theory will not be boring to more advanced readers either. He assures us that some of the most improbable paradoxes of physics have now been proven experimentally and can be explained by information theory. He does not inflict mathematical equations on readers, although occasionally he states somewhat apologetically that the reader just has to take in on faith that a really big equation makes some statement true, or at least, allows for accurate predictability. I admit to not understanding everything in the book, but Seife made the effort of trying interesting and enjoyable. ("What kind of liberation would that be," Seife quotes James Joyce as writing, "to forsake an absurdity which is logical and coherent and to embrace one which is illogical and incoherent?") I would highly recommend this book for any level of reader. (JAF) A pretty simply written account of information theory, arguing for its universal applicability. sem resenhas | adicionar uma resenha
Amazon.com Book Description (ISBN 067003441X, Hardcover)As Charles Seife reveals in this energetic new book, information theory, once the province of philosophers and linguists, has emerged as the crucial science of our time, shedding new light on the mysteries of physics, the nature of space and time and the creation and destruction of the universe itself.With his gift for making cutting-edge science accessible and entertaining, Seife explains how theorists came to understand that information is not a construct of the mind but a fundamental element of the physical world, something that sits inside every living cell and surrounds every black hole in the cosmos. It exists, like energy, even if there is no life to observe it. Starting with the breaking of the Enigma code during World War II and building momentum with the computer revolution, information theory has taken its place at the forefront of theoretical physics as scientists begin to use it to reconcile the paradoxes of relativity and quantum mechanics that have puzzled theorists since Einstein. Lucid and exhilarating, Decoding the Universe probes the mind-boggling advances that are taking us to the brink of a new understanding of the universe.
