A new edition of the New York Times bestsellernow a three-part Nova special on PBS-TV coming in Fall 2003: a fascinating and thought-provoking journey through the mysteries of space, time, and matter. Now with a new preface (not in any other edition) that will review the enormous public reception of the relatively obscure string theorymade possible by this book and an increased number of adherents amongst physicists The Elegant Universe "sets a standard that will be hard to beat" ( New York Times Book Review ). Brian Greene, one of the world's leading string theorists, peels away the layers of mystery surrounding string theory to reveal a universe that consists of eleven dimensions, where the fabric of space tears and repairs itself, and all matterfrom the smallest quarks to the most gargantuan supernovasis generated by the vibrations of microscopically tiny loops of energy. Today physicists and mathematicians throughout the world are feverishly working on one of the most ambitious theories ever proposed: superstring theory. String theory, as it is often called, is the key to the Unified Field Theory that eluded Einstein for more than thirty years. Finally, the century-old antagonism between the large and the small-General Relativity and Quantum Theory-is resolved. String theory proclaims that all of the wondrous happenings in the universe, from the frantic dancing of subatomic quarks to the majestic swirling of heavenly galaxies, are reflections of one grand physical principle and manifestations of one single entity: microscopically tiny vibrating loops of energy, a billionth of a billionth the size of an atom. In this brilliantly articulated and refreshingly clear book, Greene relates the scientific story and the human struggle behind twentieth-century physics' search for a theory of everything. Through the masterful use of metaphor and analogy, The Elegant Universe makes some of the most sophisticated concepts ever contemplated viscerally accessible and thoroughly entertaining, bringing us closer than ever to understanding how the universe works.
弦论是为了解释物质的本质而提出的概念和数学模型。质子和中子的质量似乎就是两个数值而已,但是在弦论的解释下,他们却和整数建立了完美的联系。弦论在数学上的美感是让我深深感到震撼的。我相信,一个成功的终极理论模型,必然是具有形式主义的美感,简洁而深刻。此书较深入...
评分弦论不是物理,或者说也不是科学,因为完全无法证伪。 科学其实就是找规律。打个比方,大家都做过的按规律填数。物理学通常的方法是找规律,等差、等比、指数、对数还是什么别的规律? 但是还有一个耍赖的方法,你写出来5个数,要填第六个,我就列一个五元方程组,解出来五个参...
评分因为迷TBBT的耳朵同学,于是想了解弦论,被推荐看这本书。说实话,开始没抱什么希望。俺天生就是个对物理很排斥的人,以前看过《时间简史》当时觉得我这么有限的脑容量,这辈子都不想和这些东西有什么关联~~ 这本书倒真出乎意料~~作者没有用任何的数学公式,也没有什么拗口复杂...
评分这本讲弦论的书挺开脑洞的。对于一个还没有办法被证实或者证伪,更像是一套数学框架的理论,能讲成这样已经很好了。当然我看完还是不懂弦论。最大的收获其实是怎么想象理解高维空间,另外用弦论去修正标准宇宙模型那部分也很脑洞大。 不过需要吐槽的是感觉作者写到最后不知道...
评分原书大致内容:当旋转圆盘上的人测圆周长度时,它的尺子发生了洛仑兹收缩,测的周长会比静止时大,这样周长/直径>圆周率,这样的说明是因为空间扭曲了。具体参考原本: 但如果说它测的那段圆周距离也发生洛仑兹收缩呢,测得周长也应该不变。作者后面也有解释,相对圆盘外静止...
