Are there other dimensions beyond our own? Is time travel possible? Can we change the past? Are there gateways to parallel universes? All of us have pondered such questions, but there was a time when scientists dismissed these notions as outlandish speculations. Not any more. Today, they are the focus of the most intense scientific activity in recent memory. In Hyperspace, Michio Kaku, author of the widely acclaimed Beyond Einstein and a leading theoretical physicist, offers the first book-length tour of the most exciting (and perhaps most bizarre) work in modern physics, work which includes research on the tenth dimension, time warps, black holes, and multiple universes. The theory of hyperspace (or higher dimensional space) - and its newest wrinkle, superstring theory - stand at the center of this revolution, with adherents in every major research laboratory in the world, including several Nobel laureates. Beginning where Hawking's Brief History of Time left off, Kaku paints a vivid portrayal of the breakthroughs now rocking the physics establishment. Why all the excitement? As the author points out, for over half a century, scientists have puzzled over why the basic forces of the cosmos - gravity, electromagnetism, and the strong and weak nuclear forces - require markedly different mathematical descriptions. But if we see these forces as vibrations in a higher dimensional space, their field equations suddenly fit together like pieces in a jigsaw puzzle, perfectly snug, in an elegant, astonishingly simple form. This may thus be our leading candidate for the Theory of Everything. If so, it would be the crowning achievement of 2,000 years of scientific investigation into matter and itsforces. Already, the theory has inspired several thousand research papers, and has been the focus of over 200 international conferences. Many leading scientists believe the theory will unlock the deepest secrets of creation and answer some of the most intriguing questions of all

評分有趣,深入淺齣。
評分Unification of theories in higher dimensions. 其實蠻期待最後能在哲學和宗教層麵多討論一些(喂人傢是物理科普書。寫得很生動,對我這種layman很友好,不過中間還是讀得有點吃力,怪我基礎知識太缺乏瞭。
我春节回家时坐飞机,本来飞机是下午3:20起飞,结果居然等到晚上8:20才飞。我坐在机场,没有什么事好做,就把这本书看完了。 想到买一本这样的书完全是受《生活大爆炸》的影响,想搞清一下谢耳朵同学平时研究的倒底都是些什么学问,在douban上查了一上,好像是说这本最好懂,...
評分最近持续的焦虑,导致我一直在思考人活着的意义...究竟我们为什么而活?不同的人会有不同的回答,而我一直在寻找答案,曾经我以为我已经找到,活着就是为了那些在意你关心你的人,如果你消失,会有人很伤心很难过,为了他们好好地活着。 但又不是这么简单。 《超...

評分读《超越时空》(加来道雄著)有感 现代科学理论知识常常超越于同时代大多数人的理解。翻开我们的物理习题册,不难发现基础教育仍然停留在基于牛顿定律和电磁场的应用与理解。然而截止至20世纪,人类前沿的科学家们早已展开了对时空第四维、第五维、甚至十维空间的探讨与论证...
評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...
