good old CEGEP physics-obsessed times...
評分前後看得很快,第二部分看得很痛苦,Nemesis滅絕論很有意思
評分本來想給二星,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。
評分量子和弦還是不能怎麼理解,但是有公式的都查著資料自己推導證明瞭一遍,我真覺得自己是物理天纔啊!書的結構很適閤文科生,裏麵的東西也都能看懂,推薦。

加來道雄,美籍日裔物理學傢,紐約市立大學城市學院理論物理學教授。他畢業於哈佛大學,而後獲得加州大學伯剋利分校哲學博士學位。他是《超越愛因斯坦》(與特雷納閤著)、《量子場論》和《超弦導論》諸書的作者,還曾擔任廣播電颱每周一次一小時科學節目的主持人。
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.
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...
評分人类关于物质本性的讨论,从古希腊时期就已经不停地讨论了。事实上,或许生活在这个世界上的每个人都曾经──至少可能在小时候──问过自己,我是谁,这个世界是由什么组成的,这个世界之外是什么样子的。 这样的问题或许在绝大多数成年人眼里看来毫无意义,他们只需要知道这是...
評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...
