String theory is a developing branch of theoretical physics that combines quantum mechanics and general relativity into a quantum theory of gravity. The strings of string theory are one-dimensional oscillating lines, but they are no longer considered fundamental to the theory, which can be formulated in terms of points or surfaces too.

Since its birth as the dual resonance model which described the strongly interacting hadrons as strings, the term string theory has changed to include any of a group of related superstring theories which unite them. One shared property of all these theories is the holographic principle. String theory itself comes in many different formulations, each one with a different mathematical structure, and each best describing different physical circumstances. But the principles shared by these approaches, their mutual logical consistency, and the fact that some of them easily include the standard model of particle physics, has led many physicists to believe that the theory is the correct fundamental description of nature. In particular, string theory is the first candidate for the theory of everything, a way to describe all the known natural forces (gravitational, electromagnetic, weak and strong interactions) and matter (quarks and leptons) in a mathematically complete system.

Many detractors criticize string theory because it has not yet provided quantitative experimental predictions. Like any other quantum theory of gravity, it is widely believed that testing the theory directly by experiment would require prohibitively expensive feats of engineering. Whether there are stringent indirect tests of the theory is not yet known.

String theory is of interest to many physicists because it requires new mathematical and physical ideas to mesh together its very different mathematical formulations. One of the most inclusive of these is the 11-dimensional M-theory, and in the M-theory way of thinking, string theory requires spacetime to have eleven dimensions, as opposed to the usual three space and one time. The original string theories from the 1980s describe special cases of M-theory where the eleventh dimension is a very small circle or a line, and if these formulations are considered as fundamental, then string theory requires ten dimensions. But the theory also describes universes like ours, with four observable spacetime dimensions, as well as universes with up to 10 flat space dimensions, and also cases where the position in some of the dimensions is not described by a real number, but by completely different type of mathematical quantity. So the notion of space-time dimension is not a fixed thing in string theory: it is best thought of as different in different circumstances.

String theories include objects more general than strings, called branes. The word brane, derived from "membrane", refers to a variety of interrelated objects, such as D-branes, black p-branes and Neveu-Schwarz 5-branes. These are extended objects that are charged sources for differential form generalizations of the vector potential electromagnetic field. These objects are related to one-another by a variety of dualities. Black hole-like black p-branes are identified with D-branes, which are endpoints for strings, and this identification is called Gauge-gravity duality. Research on this equivalence has led to new insights on quantum chromodynamics, the fundamental theory of the strong nuclear force.

每个周二夜晚的8：20到8：30的十分钟是舒爽而轻快的，除去周一晚是法定聚餐夜之外，在80分钟的古希腊哲学的熏陶之后思想总如脱缰的野马一样奔驰，如海潮一般翻涌不息。正如前一句比喻句一样，这种修辞手法很有古希腊的感觉。

每个这个夜晚的这个十分钟，阿飞会跟你谈onto、being、普罗太哥拉、阿奎那等等专有名词，以及企图用语言的方式驳倒关于“真理越辩越明”这一论题，以彰显其学院派的风格。阿飞的学院派属性由来已久，可追溯到这个学期初他请教西方文论的李克的那一刻，李克师以一句“你有没看过柏拉图《理想国》的第十卷第一章”完胜阿飞君。此后，阿飞奋发图强，从他最终蹦出来的哲学专业词汇我一个都不认得。

关于哲学的对话我一路处于下风，但是我的有点在于思想之奔逸，在阿飞开始论述什么是诠释学的时候我以侧面攻击之：“你知道什么是薛定谔的猫吗？”往往这样的问题会让我立于不败之地，继而我开始他那本《什么是生命》（我也没读过）开始谈起，然后扯出沃森和克里克和双螺旋结构，在说出沃森和克里克的PH.D与生命科学无关，这几个关键词基本可以让你在外行人面前显得足够见多识广。如果对方困兽犹斗企图回光返照回问你“那什么是薛定谔的猫”的时候，你就需要将薛定谔的猫的小故事理解清楚，最好能够用英语说出薛定谔的名字（这点我暂未能做到），然后在清楚地表达出“叠加状态”、“衰变”等几个术语，这基本可以使得你在这场学术交锋中大获全胜。

这个方法的唯一一个缺点就是对手也很容易掌握，所以在你问“什么是薛定谔的猫”之后对方有可能用相同的句式来一个“那什么是**”的句型予以反击，这种方法在古希腊被称为反诘法。（今天刚学的词汇）因此，你需要具备良好的心理素质和灵巧的应变方法，当然最需要的就是强大的词汇量，无论是什么学科，只要你认为对方不够专业。接下来的词汇大战中可能会出现自然主义，休克疗法，克尔凯郭尔，孙子兵法，孙武兵法等等，当然最好还是能掌握多门语言然后用最native的原词表达会让你在心理上增加多一份优势。

值得一提的是需要避免一些同音词带来的误解，诸如“衍射”和“颜射”——一个是物理学光学范畴，另一个可以联系到佛洛依德精神分析论；还有一词多义的现象，诸如“打枪”——第一个意思可以可能涉及空气动力学，另外一个自然是生理学范畴。

今夜的十分钟，在科技楼偶遇同斋的斋友（非佛学范畴的斋友），然后和阿飞君和陈枫君将其雷得外焦内嫩，飘逸的话题让50m回宿舍的路对他来说变得如光年般远，对我们来说如芥子之间。这朴素的相对论思想最终让他说了一句“你们太能吹了”或者类似的句子戛然而止，我还未来得及“如今就业形势困难多掌握一门知识就是多一种求职手段”的现实意义的话语做一个总结他便消失在云雾的海桐当中。

最后，在海桐楼下看到老大和阿jo正用猫粮轻易诱拐一只猫咪的之后，我脑海中突然蹦出个词来“人性的，太人性的”，然后再自我纠正，“哦，是猫。”

曾在《今日先锋》中看到一个叫胡吗个的人写的一篇《唱片、小说、DV带，最后我们谈厨艺》，觉得这种跳跃式的组合与本文暗合，因此，拟此篇名为《哲学、生命、艺术，最后我们谈谈吹水》

nothing

It is for it is impossible for it not to be.Non-being you can not recognize it and you can not speak of it.It is same thing that can be and can be thought.

越长越大，勇气却越来越小。这种勇气不关坐过山车，而关漂泊。我年少时听闻家乡某已成功多年的商人把座驾卖光、房屋抵押，准备第二次创业。那时我似乎认为没什么大不了的。时至近年，当我不再是十七八岁的“小火子”的时候回想起那位邻居，发现那样的勇气实属难得。我想需要一连排的排比句才能抒发我对时光和勇气一同流逝的感慨。

有人说可以选择是人生最幸福的事情。还有人说太多的选择是人生痛苦的根源。上帝是否真如老钱所说是顽皮的小孩，在不断推翻你的积木的同时为你制造出不同形状的积木，让你一次次重构你的城堡的时候增加它的可能性。当你已经没有年少的勇气的时候每逢分岔路口都会踌躇良久，害怕顾此失彼。我怀疑其实人生是有终极价值的，那便是在你完成固定数量的选择之后。而大多数人无法达到的原因是因为在选择中浪费了时间。

《肖申克的救赎》里，弗里曼说：“海明威说过，这个世界是美好的，是值得我们去奋斗的。我只相信后边一句。”同时我想起另外一句话，丁尼生（Tennyson）所说：“时间和命运产生软弱，但需要意志坚强。”

总觉得今天过得特别的丰富，其中包括了收稿费，吃早餐，洗衣服（机洗），打羽毛球，喝佳得乐，和pt志欣阿飞吃小炒，在路边吃菠萝，练字，朗读诗歌，dictation等一系列事件。

今夜星空朗朗，一弯新月在天。就在我朗读诗歌之中，对面宿舍人称红榴斋的歌声穿行树叶而至，在这个有风的夜晚。

今晚朗诵的诗歌是《春江花月夜》。
