The central theme of the book is the way all these forms of ordered space were reshaped by the project of unification and how, at the same time, that unification was constrained and...(展开全部)

Einstein said that the most incomprehensible thing about the universe is that it is comprehensible. But was he right? Can the quantum theory of fields and Einstein's general theory of relativity, the two most accurate and successful theories in all of physics, be united in a single quantum theory of gravity? Can quantum and cosmos ever be combined? On this issue, two of the wor...(展开全部)

A brilliantly clear and penetrating exposition of developments in physical science and mathematics brought about by the advent of non-Euclidean geometries, including in-depth coverage of the foundations of geometry, the theory of time, Einstein’s theory of relativity and its consequences, other key topics.

作者：艾萨克·阿西莫夫（1920-1992） 俄裔美籍作家，被全世界的读者誉为“神一样的人”；美国政府授予他“国家的资源与自然的奇迹”这个独一无二的称号，以表彰他在“拓展人类想象力”上做出的杰出贡献。 阿西莫夫是一个全知全能的作家，其著作几乎覆盖人类生活的一切方面，上天下海、古往今来、 从恐龙到亚原子到全宇宙无所不包，从通俗小说到罗马帝国史，从科普读物到远东千年历史，从圣经指南，到科学指南，到两性生活指南，每一部著作都朴实、严谨而又充满幽默风趣的格调，为了尽情发挥自己诙谐搞笑的天赋，他甚至还写过一本《笑话集》。 到了晚年，他开始变得“好色”，出版了一系列两性话题的“黄书”。 他提出的“机器人学三定律”是当代机器人研究的基本法则，他预言了今天的生物科技，预言了互联网时代的数字图书馆，预言了人类将进行太空殖民。 终其一生，阿西莫夫最引以为豪的则是：《银河...(展开全部)

High above the planet Florinia, the Squires of Sark live in unimaginable wealth and comfort. Down in the eternal spring of the planet, however, the native Florinians labor ceaselessly to produce the precious kyrt that brings prosperity to their Sarkite masters. Rebellion is unthinkable and impossible. Not only do the Florinians no longer have a concept of freedom, any disruptio...(展开全部)

Henri Lefebvre has considerable claims to be the greatest living philosopher. His work spans some sixty years and includes original work on a diverse range of subjects, from dialectical materialism to architecture, urbanism and the experience of everyday life. The Production of Space is his major philosophical work and its translation has been long awaited by scholars in many d...(展开全部)

Maintaining the standard of excellence set by the previous edition, this textbook covers the basic geometry of two- and three-dimensional spaces Written by a master expositor, leading researcher in the field, and MacArthur Fellow, it includes experiments to determine the true shape of the universe and contains illustrated examples and engaging exercises that teach mind-expandin...(展开全部)
