内容简介

　　Recent years have brought a revival of work on string theory, which has been a source of fascination since its origins nearly twenty years ago.There seems to be a widely perceived need for a systematic, pedagogical exposition of the present state of knowledge about string theory. We hope that this book will help to meet this need. To give a comprehensive account of such a vast topic as string theory would scarcely be possible,even in two volumes with the length to which these have grown. Indeed,we have had to omit many important subjects, while treating others only sketchily. String field theory is omitted entirely (though the subject of chapter 11 is closely related to light-cone string field theory). Conformal field theory is not developed systematically, though much of the background material needed to understand recent papers on this subject is presented in chapter 3 and elsewhere.

性价比很高 书是正版的，之前有过担心滴。内容还行吧，尽管我没觉得有多充实。冲着是名人写的，书的质量还行就不挑剔了。卖家发货挺快的，第二天就收到了。书还是不错的，精装外壳，发货速度真心的快，评价晚了，书不错，应该再早点看的。推荐看，只是粗浅认识了一下，已经感觉到自己逻辑思维更加清晰。好书，受益匪浅，如果不好好研究一下此书，绝对是人生一大遗憾。这天女友打电话问我借本书，说她写作需要参考，我说我家没有，但我可以帮你找。我一边接电话一边就上网搜索，很快找到，立马告诉她网上京东有。她说我不会在网上买书啊。我嘲笑她一番，然后表示帮她买。很快就写好订单写好她的地址发出去了。果然第二天，书就送到她那儿了。她很高兴，我很得意。过了些日子，我自己又上网购书，但下订单后，左等右等不来。以前从来不超过一星期的。我正奇怪呢，刘静打电话来笑嘻嘻地说，哎，也不知道是谁，心眼儿那么好，又帮我订了好几本书，全是我想要的，太好了。我一听，连忙问她是哪几本？她一一说出书名，晕，那是我买的书啊。原来我下订单的时候，忘了把地址改过来，送到她那儿去了。这下可把她乐死了，把我先前对她的嘲笑全还给我了。不过京东送货确实很快。我和女友都很满意。好了，废话不说。|好了，我现在来说说这本书的观感吧，坐得冷板凳，耐得清寂夜，是为学之根本；独处不寂寞，游走自在乐，是为人之良质。潜心学问，风姿初显。喜爱独处，以窥视内心，反观自我；砥砺思想，磨砺意志。学与诗，文与思；青春之神思飞扬与学问之静寂孤独本是一种应该的、美好的平衡。在中国传统文人那里，诗人性情，学者本分，一脉相承久矣。现在讲究“术业有专攻”，分界逐渐明确，诗与学渐离渐远。此脉悬若一线，惜乎。我青年游历治学，晚年回首成书，记忆清新如初，景物历历如昨。挥发诗人情怀，摹写学者本分，意足矣，足已矣。现在，京东域名正式更换为JDCOM。其中的“JD”是京东汉语拼音（JING DON|G）首字母组合。从此，您不用再特意记忆京东的域名，也无需先搜索再点击，只要在浏览器输入JD.COM，即可方便快捷地访问京东，实现轻松购物。名为“Joy”的京东吉祥物我很喜欢，TA承载着京东对我们的承诺和努力。狗以对主人忠诚而著称，同时也拥有正直的品行，和快捷的奔跑速度。太喜爱京东了。|给大家介绍本好书《我们如何走到这一步》自序：这些年，你过得怎么样我曾经想过，如果能时光穿梭，遇见从前的自己，是否可以和她做朋友。但我审慎地不敢发表意见。因为从前的自己是多么无知，这件事是很清楚的。就算怀着再复杂的爱去回望，没准儿也能气个半死，看着她在那条傻乎乎的路上跌跌撞撞前行，忍不住开口相劝，搞不好还会被她厌弃。你看天下的事情往往都是一厢情愿。当然我也忍住了各种吐槽，人总是要给自己留余地的，因为还有一种可能是，未来的自己回望现在，看见的还是一个人。好在现在不敢轻易放狠话了，所以总算显得比年轻的时候还有一分从容。但不管什么时候的你，都是你。这时间轴上反复上演的就是打怪兽的过程。过去困扰你的事情，现在已可轻易解决，但往往还有更大的boss在前面等你。“人怎么可能没有烦恼呢”——无论是你初中毕业的那个午后，或者多年后功成名就那一天，总有不同忧伤涌上心头：有些烦恼是钱可以解决的，而更伤悲的是有些烦恼是钱解决不了的。我们曾经在年少时想象的“等到什么什么的时候就一切都好起来了”根本就是个谬论。所以，只能咬着牙继续朝前走吧。

书的质量勉强吧，基本是油印，算不得影印。封皮太薄，果然是普通版。但是对于弦理论的知识来说，值得这个价了，英文版。
