Already thoroughly familiar to the seasoned science fiction fan, Hyperspace is that realm which enables a spaceship captain to take his ship on a physics-defying shortcut (or "wormhole") to the outer shores of the Galaxy in less time than it takes a 747 to fly from New York to Tokyo. But in the past few years, physicists on the cutting edge of science have found that a 10-dimensional Hyperspace may actually exist, albeit at a scale almost too small to comprehend, smaller even than a quark; and that in spite of its tiny size, it may be the basis on which all the forces of nature will be united. This is the first book for a general audience on one of the latest, most exciting developments in modern science. In the past several years, theoretical physicists--the author among them--have discovered that the universe exists not merely in the four spacetime dimensions (3 of space + one of time) with which Einstein made us familiar, but rather as a ten-dimensional Hyperspace. Once the domain of the science fiction writer or the occultist, Hyperspace has recently been shown to be the only kind of space in which the laws of modern physics can be satisfactorily explained. Amazingly enough, many of the phenomena whose explanations have stymied 20th century physicists and cosmologists can now be perfectly clarified by using the ten dimensions of Hyperspace. Most importantly, Einstein's unfulfilled dream, the work on which he spent the last several decades of his life in vain--the unification of all the forces of nature--now sits waiting on the ten-dimensional doorstep of modern theoretical physicists. Michio Kaku--theoretical high-energy physicist, author, radio talkshow host, and nuclear disarmament activist--is one of the pioneers in the field of String Theory, which states that the basic constituents of our universe are not quarks or protons or electrons, but much smaller entities called "strings" or "superstrings", which vibrate--like violin strings--in 10 dimensional Hyperspace, and whose vibrations in different resonances are manifested in the elementary particles. In his book, Kaku takes the reader on a ride through Hyperspace to the edge of physics. On the way he gives crystal clear explanations of such formidable mathematical concepts as non-Euclidean Geometry, Kaluza-Klein Theory, and Supergravity, the everyday tools of the string theorist. Utilizing fascinating and often hilarious anecdotes from history, from art, and from science fiction, Kaku shows us that writers and artists--in addition to scientists--have been fascinated by multidimensional space for over a century. In fact, many of the weird effects created by such famous artists as Dali and Picasso can be explained and more appreciated with an eye on the fourth spatial dimension. Finally, Kaku shows us why the ability to master Hyperspace may be our only salvation from destruction at the end of space-time. This lively yet authoritative book is spiced with many whimsical illustrations in a style reminiscent of the late science writer George Gamow.

本來想給二星,想瞭一想,覺得還沒那麼糟,至少首次瞭解瞭超弦理論、十維空間……當然,未經證實的平行時空,是否存在,依然存疑。

此书梳理了黎曼几何→相对论→量子力学→弦论,这条近一百年的物理学逼近我们世界真相的道路,特别是几何空间→微观粒子→高维几何空间,这样一个在高维中将自然规律简化的曲折发展历程。 此书的优点在于,作者多年浸淫在现代物理的奇妙世界中,对主要理论的来龙去脉都异常清晰...
評分与这本书结缘既是一个偶然,也是一个必然。当年我大二的时候,在学校图书馆中找到了这本书,翻开第一页后,就被那几段开篇的文字深深吸引。我在图书馆中如饥似渴地阅读它,甚至读到困倦不堪趴在书桌上睡着了。也许是因为书的内容太过激动人心,我竟做了一个二类文明在四维宇宙...
評分两年前因为谢耳朵,想了解下他所从事的超弦理论,就买了《超越时空》,之后豆瓣“在读”的标志两年都没有发生更改,当时读到量子学说部分就读不下去了,觉得实在是艰深只好放弃,借着有人推荐的契机,终于又重新读起来,只觉得这次相遇是最好的时间,我有了一定的知识储备去理...
評分几年前因为东方秘封组的关系忽然对“超弦理论”有了兴趣 阐述弦理论最好的著作当然是B.格林写的《宇宙的琴弦》 某位数学狂人跟我说这位格林是当代数学最好的物理学家同时也是物理最好的数学家 虽说《宇宙的琴弦》定位就是科普读物 但还是要有一些数理基础才能看得懂的 而这本加...
評分黎曼: 1.他用高维空间简化了自然规律;即对他而言,电磁以及引力仅仅是由超维空间的褶皱或弯曲所引起的结果。 2.他讨论了虫洞的概念。黎曼切口是多连通空间的最简单范例。 3.他把引力表述为场。由于度规张量(借助于曲率)描述了空间任一点的引力,因此说当把度规张量用于引力...
