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.
极其优秀的科普著作。三体只不过是这本书的小说化的改写。二十年后中国才翻译这本书,太晚了。 p9 从树木和山脉到恒星本身,只不过是超空间中的振动。平行宇宙中的蛀洞或者管道网的可能性是存在的。 p3 我想知道上帝怎样创造了这个世界,对这样或那样的具体现象我不太感兴趣。...
评分当代物理学的发展历史可以概括为两大趋势和力量,第一股力量,即物理学渐渐由可以感知的世界发展到不可以感知的世界,从可以感知的变量发展为不可感知的变量。以光的传播为例,先前物理学家认定光是一种波,但是波的传播需要介质,于是物理学家假定有一种看不见的“以太”存在...
评分为什么地球人至今寻找不到其他星际文明? (327页到329页书摘) 一种解释是,地球智慧生命史(百万年),相对于宇宙时间尺度(数十亿年)而言,只是一瞬间;因此有理由假设许多智慧生物在人类存在之前已经消亡,也有更多星际文明尚未发展起来。 另一种解释是,当我们在田野中散...

评分十年前就看过了这本书。已经忘记了到底是为的什么买的这本书,可能只是随便一翻,随后就翻到了那个现在看来也超牛无比的一个人在时空中旅行成为了自己的生父、生母、女儿、儿子以及安排自己进行时空旅行的人。这就是鼎鼎大名的Robert Heinlein的All you zombies,他是写过《星...
本来想给二星,想了一想,觉得还没那么糟,至少首次了解了超弦理论、十维空间……当然,未经证实的平行时空,是否存在,依然存疑。
评分量子和弦还是不能怎么理解,但是有公式的都查着资料自己推导证明了一遍,我真觉得自己是物理天才啊!书的结构很适合文科生,里面的东西也都能看懂,推荐。
