With such compelling and provocative novels as Red Planet Blues , FlashForward and The WWW Trilogy, Robert J. Sawyer has proven himself to be “a writer of boundless confidence and bold scientific extrapolation” ( New York Times ). Now, the Hugo and Nebula Award-winning author explores the thin line between good and evil that every human being is capable of crossing… Experimenta...(展开全部)

罗伯特·J·索耶是加拿大最有影响力的科幻作家，自1990年发表第一部长篇小说《金羊毛》以来，已经出版了二十多本科幻小说，多次获雨果奖、星云奖等各种重要的科幻奖项，被誉为“加拿大科幻的教长”。 索耶的科幻小说涉及多种主题，从平行时空、太空侦探到电脑狂魔、恐龙复活，想像奇伟，异彩纷呈，代表作除了“恐龙文明三部曲”外，还有《计算中的上帝》和《星丛》等。 “恐龙文明三部曲”包括《远望》、《化石猎人》和《异族》，充分展现了索耶强大的写作能力和独特的风格，被纽约公共图书馆评为当年“最佳青少年丛书”。

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)
