Stag's Leap is a stunningly poignant sequence of poems that tells the story of a divorce, embracing strands of love, sex, sorrow, memory, and new freedom. In this wise and intimste telling——which carries us through the seasons when her marriage was ending——Sharon Olds opens her heart to the reader, sharing the feeling of invisibility that comes when we are no longer standing i...(展开全部)

It is now forty years after Mao Zedong’s death and the end of the Cultural Revolution, and more than fifty years since the Great Leap Forward and the Great Famine. During this time, the collective memory of these events has been sanitized, reduced to a much-diluted version of what truly took place. Historical and sociological approaches cannot fully address the moral failure th...(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)

在线阅读本书 Beginning students of quantum mechanics frequently experience difficulties separating essential underlying principles from the specific examples to which these principles have been historically applied. Nobel–Prize–winner Claude Cohen–Tannoudji and his colleagues have written this book to eliminate precisely these difficulties. Fourteen chapters provide a clarity of org...(展开全部)

This textbook on "Quantum Electrodynamics" is a thorough introductory text providing all necessary mathematical tools together with many examples and worked problems. In their presentation of the subject the authors adopt a heuristic approach based on the propagator formalism. The latter is introduced in the first two chapters in both its non relativistic and relativistic versi...(展开全部)

Quantum gravity is perhaps the most important open problem in fundamental physics. It is the problem of merging quantum mechanics and general relativity, the two great conceptual revolutions in the physics of the twentieth century. The loop and spinfoam approach, presented in this 2004 book, is one of the leading research programs in the field. The first part of the book discus...(展开全部)

Quantum gravity poses the problem of merging quantum mechanics and general relativity, the two great conceptual revolutions in the physics of the twentieth century. The loop and spinfoam approach, presented in this book, is one of the leading research programs in the field. The first part of the book discusses the reformulation of the basis of classical and quantum Hamiltonian ...(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)
