Unification of theories in higher dimensions. 其实蛮期待最后能在哲学和宗教层面多讨论一些(喂人家是物理科普书。写得很生动,对我这种layman很友好,不过中间还是读得有点吃力,怪我基础知识太缺乏了。
评分写得很有趣
评分有趣,深入浅出。

加来道雄,美籍日裔物理学家,纽约市立大学城市学院理论物理学教授。他毕业于哈佛大学,而后获得加州大学伯克利分校哲学博士学位。他是《超越爱因斯坦》(与特雷纳合著)、《量子场论》和《超弦导论》诸书的作者,还曾担任广播电台每周一次一小时科学节目的主持人。
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
书刚刚到货的时候,看着厚厚的书页和密密麻麻的字,总觉得自己会看不下去。但是看了之后发现,真的引人入胜,尤其是前半部分描述四维时空,每读完一部分总要停下来回味思考一番,读完也是感觉意犹未尽。 在古代我们不能通过仪器观察到整个地球的时候,肯定会觉得地球是个球体是...
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...
评分在高维中探索时间旅行,超弦理论统一十维宇宙,物理学定律将在高维中得到简化! 超空间理论认为:我们的宇宙存在于四维时空以外的更高维度;它预言了超空间的精确维度是十维;它可以将所有已知的自然力统一起来;它可以计算时空曲率及打开虫洞所需的精确能量;它的高级表现形式...
评分黎曼: 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...
评分如果黎曼-爱因斯坦-卡鲁查-克莱因等老师的方向是正确的、那么如果在我们可以观察的空间中存在不平坦、这可能就足以说明更高维数是一定存在的、而不只是、比如说、是为啦在理论计算上的需要 也就是说、即使更高的维数不可观察、但是只要可观察的空间是不平坦的、那么这就足以说...
