Earth Sound Earth Signal is a study of energies in aesthetics and the arts, from the birth of modern communications in the nineteenth century to the global transmissions of the present day. Grounded in the Aeolian sphere music that Henry David Thoreau heard blowing in telegraph lines and in the Aelectrosonic sounds of natural radio that Thomas Watson heard in telephone lines, t...(展开全部)

The long-awaited new novel by the award-winning, bestselling author of Startide Rising and The Uplift War--an epic novel set fifty years from tomorrow, a carefully-reasoned, scientifically faithful tale of the fate of our world. "One hell of a novel . . . has what sci-fi readers want these days; intelligence, action, and an epic scale".--Isaac Asimov's Science Fiction Magazine....(展开全部)

TIME IS RUNNING OUT Decades from now, an artificial black hole has fallen into the Earth's core. As scientists frantically work to prevent the ultimate disaster, they discover that the entire planet could be destroyed within a year. But while they look for an answer, some claim that the only way to save Earth is to let its human inhabitants become extinct: to reset the evolutio...(展开全部)

This text is a comprehensive introduction to the main ideas and techniques of the field of quantum computation and quantum information. Until now, the rapid rate of progress and its cross-disciplinary nature have made it difficult for newcomers to the field to obtain a broad overview of the most important techniques and results. Michael Nielsen and Isaac Chuang ask the questio...(展开全部)

Quantum physics is notable for its brazen defiance of common sense. (Think of Schrödinger's Cat, famously both dead and alive.) An especially rigorous form of quantum contradiction occurs in experiments with entangled particles. Our common assumption is that objects have properties whether or not anyone is observing them, and the measurement of one can't affect the other. Quant...(展开全部)

Simple enough for students yet sufficiently comprehensive to serve as a reference for working physicists, this classic text is celebrated for its clarity and coherence of presentation as well as the author’s fluid and literate style. Subjects include a detailed treatment of formalism and its interpretation, an analysis of simple systems, symmetries and invariance, methods of ap...(展开全部)
