F*ck? 握草？ God Lu? 陆神？ Idol! 偶像啊！ Sees that person that stands, opens celebrates has almost not fallen the eyeglasses on the ground. 看到站起来的那人,张中庆差点没把眼镜掉在地上。 Thinks this big shot sat in oneself classroom unexpectedly listened to such half-day class, his mood at this moment was really pleasantly surprised, looked like the lottery ticket simply. What startled has not noticed completely, what is happy is goes out can boast, we also rewarded the person who the big shot has attended class. 一想到这位大佬竟然坐在自己教室里听了这么半天的课,他此刻的心情真是又惊又喜,简直就像是中了彩票。惊的是完全没有注意到,喜的是出门可以和人吹牛,咱也是给诺奖大佬上过课的人了。 However, has mixed emotions at heart, but Lu Zhou that although in opening celebrates to no feeling. 不过,虽然张中庆的心里百感交集,但陆舟到没什么感觉。 The classroom is also one of the academic exchanges places. 课堂本身也是学术交流的场所之一。 Before Princeton, he also came up to say for oneself by own student frequently. 以前在普林斯顿的时候,他也经常让自己的学生上去替自己讲。 At least in his opinion, exchanges academic does not divide the position and honor height. 至少在他看来,交流学术是不分地位、荣誉高低的。 „Professor land invited.” Professor stretch/open gives the hand signal of invitation immediately, give away the platform respectfully. “陆教授请。”张教授立刻做了个请的手势,恭敬地让出了讲台。 „Does not use such politely, I happen to am only a little idea.” “不用这么客气,我只是正好有点想法。” Looks the movement that he modestly declines, Lu Zhou smiles embarrassed. 看着他谦让的动作,陆舟不好意思地笑了笑。 Continued the smalltalk to lose the time. 继续客套太耽误时间了。 Person who he does not love the smalltalk. 况且他本身也不是爱客套的人。 Arrived at the blackboard advance party to decide, Lu Zhou picked up a chalk. 走到了黑板前站定,陆舟拾起了一支粉笔。 „This issue is not the undergraduate student can be solved, besides needs the thorough understanding of the quantum color dynamics, but also needs deep grasping to the functional analysis.” “这种问题不是本科生能解决的,除了需要对量子色动力学有着深入的了解之外,还需要对泛函分析有着较深的掌握。” Stopped for two seconds, Lu Zhou continued saying that „, but, actually did not have everyone to imagine was so complex.” 停顿了两秒,陆舟继续说道,“不过,其实也没大家想象中的那么复杂。” Saying, chalk seal in hand on blackboard, Lu Zhou blackboard writing while the calculation said. 说着,将手中的粉笔印在了黑板上,陆舟一边板书一边演算道。 „From field theory Move out, makes Feynman diagram, can obtain using the Feynman rule computation scattering amplitude......” “从场论出发,作费曼图,利用费曼规则计算散射振幅能得到……” 【Im =( ig2 / | p'-p | 2 + m φ 2) 2 m ^ ss' 2 m δ ^ rr'】 【im=(ig2/|p'-p|2+mφ2)2m^ss'・2mδ^rr'】 【......】 【……】 „Mφ expressed that the quality of corresponding boson, g came from interaction Rumsfeld measures the coupling constant. Previous calculating procedure union with Professor stretch/open, can obtain v ( q ) through the scattering cross section......” “其中mφ表示相应玻色子的质量,g来自于相互作用拉氏量中的耦合常数。与张教授先前的计算步骤结合,可以通过散射截面求得v(q)……” 【V ( q) =-g 2 /( | Q | 2 + m φ 2)】 【v(q)=-g2/(|q|2+mφ2)】 Writes about here, Lu Zhou stopped the chalk in hand, then looked to the lecture amphitheater, or a face compelled or earnest ignorant the students of listening, smiles. 写到这里,陆舟停下了手中的粉笔,回头看向了阶梯教室里,或一脸懵逼或认真在听的学生们,笑了笑说。 „The above is simple, the following step will use some skills.” “以上都还算简单,不过接下来的这一段步骤会用到一些技巧。” Students: „......” 众学生:“……” mmp! mmp！ Where was simple??? 到底哪里简单了？？？ Stands in that looks at to celebrate is also bewildered. 站在旁边看着的张中庆也是一脸茫然。 He cannot understand actually not, but is he really cannot believe, some unexpectedly people can infer in such a short time these thing scenes. 倒不是他看不懂,而是他实在不敢相信,竟然有人能在如此短的时间内把这些东西现场推导出来。 This person calculates does not need to spend the time to cross the brain? 难道这人计算都不需要花时间过脑的吗？ If so, that was also too terrifying...... 如果真是这样,那也太恐怖了…… Has not made any stay, said that Lu Zhou of those words, turned around to face the blackboard again, said superficially. 没有做任何停留,说完了那句话的陆舟,转身再次面向了黑板,轻描淡写地说道。 „Makes the Fourier contrary transform to it!” “对其做傅里叶逆变换！” The chalk rubs the blackboard the sound is getting quicker and quicker, of standing celebrates the expression is also shock even more. Under student as for stage, then looks at the blackboard at a loss, even if has turned the textbook ahead of time study the tyrant, is facing that complex computational process, is still a face helpless expression. 粉笔摩擦黑板的唰唰唰声越来越快,站在旁边的张中庆表情也是愈发的震撼。至于台下的学生,则是茫然地看着黑板,即便是早已提前翻完了课本的学霸,面对着那复杂的计算过程,也是一脸不知所措的表情。 But at this moment, Lu Zhou has not noticed their expression actually, has completely immersed in own world. 而此时此刻,陆舟倒是没有注意到他们的表情,已经全然沉浸在了自己的世界中。 Indeed, this is the things of some foundations, but did not have the foundation to attend the meeting to appear in the degree on sample question or examination paper. 诚然,这都是一些很基础的东西,只是还没有基础到会出现在例题或者考卷上的程度。 However with thorough ponders of these foundation issues, as the step on blackboard are getting more and more, that clear(ly) in his heart became aware is also getting more and more clear. 然而随着对这些基础问题的深入思考,随着黑板上的步骤越来越多,他心中的那一丝明悟也越来越清晰了。 Why can the strong acting force only affect in the extremely short distance? 为什么强相互作用力只能作用在极短的距离？ Changes a view, is what lets the nucleon, only then can form the atomic nucleus under the short distance extremely? 或者换个说法,是什么让核子只有在极短距离下才能形成原子核？ Answer obvious...... 答案显而易见…… 【......】 【……】 【V ( r ) =-g 2 / 4 π r e ^(- mφr)】 【v(r)=-g2/4πr・e^(-mφr)】 The chalk in hand stops, looks at the mathematical formula on blackboard, Lu Zhou says slowly. 手中的粉笔停下,看着黑板上的算式,陆舟缓缓开口说道。 „What electromagnetic interaction exchange is the photon, the quality of photon is zero, therefore regarding electromagnetic interaction, V direct proportions and 1 / r.” “电磁相互作用交换的是光子,光子的质量为零,所以对于电磁相互作用来说,v正比与1/r。” „Among the nucleon what provides the nuclear potential is the meson of function in nucleons, the quality is about 200 mev, leading into the computation can estimate, only then distance in 10 lost/carrying 14 power of exponent magnitudes. The nuclear potentials of function among two protons, can counter-balance the electromagnetism repulsion between protons, has the fusion reaction.” “为核子提供核力的是作用在核子之间的介子,质量约为200mev,带入计算可以估算出,只有距离项在十的负十四次方这个数量级上。作用在两质子之间的核力,才能抵消质子间的电磁斥力,发生聚变反应。” The applause starts to resound from the first row. 掌声从第一排开始响起。 Like whipping the ocean waves of shore, is proliferating to the back row. 如同拍打着岸边的海浪,向后排扩散。 Professor stretch/open of standing , is not applauding voluntarily. 站在旁边的张教授,也是不自觉地鼓起了掌。 Regarding most students, possibly watches the fun. 对于大多数学生来说,可能只是看了个热闹而已。 But to him, he actually saw one type about the nuclear potential distance, simpler solution method...... at least compared with that two succinct many that he remembers. 但对于他而言,他却是看到了一种关于核力距离,更简便的求解方法……至少比他记得的那两种简洁的多。 Unbelievable, these are in less than ten minutes, complete on the spot...... 难以置信,这些都是在不到十分钟的时间里,现场完成的…… At this moment shock in his heart, perhaps only then he was clear. 此时此刻他心中的震撼,恐怕只有他自己才清楚了。 Meanwhile, on platform. 与此同时,讲台上。 Although the classroom had been filled up by the applause, but stands Lu Zhou before blackboard, at this moment still immersed in own world, when the applause stops, completely has not noticed. 虽然教室已经被掌声填满,但站在黑板前的陆舟,此刻仍然沉浸在自己的世界中,以至于当掌声停下,都全然没有注意到。 Regarding previously that simple issue, calculated these step to finish. 对于先前那个简单的问题而言,计算到这一步就已经结束了。 However, the issue that he ponders actually is not only only this. 然而,他所思考的问题却不仅仅只是这个。 According to the quantum field theory and viewpoint in quantum color dynamics, four big fundamental forces and traditional granules can achieve the unification. 根据量子场论、量子色动力学中的观点,四大基本力和传统粒子是可以达到统一的。 For example, when the time and space different positions, the weight/quantity of electric field can construct the operator of non- exchange, when constructs the Hilbert space that these operators affect, traditional granule- for example the electron, can be explained for the quantization of Dirac Field. 比如,在时空不同位置时,电场的分量可以构造成非交换的算子,当构造这些算子所作用的希尔伯特空间时,传统的粒子-例如电子,可以被重新解释为狄拉克场的量子化。 But then, the difference between field and granule then vanished. 而如此一来,场与粒子之间的差别便消失了。 With a succinct mathematical formalism, like the weinberg-salam-glashow weak electronic unification theory, could describe the electromagnetic force and weak acting force with some unified way, describes strong interaction, and the electromagnetism action achieves the unification it? 能否用一种简洁的数学形式,像weinberg-salam-glashow弱电统一理论,用某种统一的方式描述了电磁力与弱相互作用力那样,去描述强相互作用,并且将其和电磁作用力达成统一？ Replied that this issue cannot solve the miniaturization of Controlled Nuclear Fusion, impossible to bring innovation in any degree to the existing Controlled Nuclear Fusion technology, but the intuition told Lu Zhou, if can solve this problem theoretically, could to solve this problem provides a clue, or mentality...... 回答这个问题不能解决可控聚变的小型化,也不可能对现有的可控聚变技术带来任何程度上的革新,但直觉告诉陆舟,如果能够从理论上解决这个问题,或许可以为解决这个问题提供一条线索,或者说思路…… Naturally, wants to achieve this point is not easy. 当然,想要做到这一点不容易。 For example, the strong acting force and weak acting force are different, it has a very typical problem...... 比如,强相互作用力和弱相互作用力不同,它存在一个很典型的问题…… The bell sound, Lu Zhou motionless standing there, seems to be pondering anything as before. 下课铃声响了,陆舟依旧是一动不动的站在那里,似乎在思考着什么。 Sees Lu Zhou not to respond, in opening celebrates is not good to announce arbitrarily finishes class, does not dare to disturb his mentality. 见陆舟没反应,张中庆也不好擅自宣布下课,更不敢打扰到他的思路。 Crossed for probably ten minutes is so long. 就这么过了大概十分钟那么久。 Stares on the blackboard an all various professions succinct mathematical formula, Lu Zhou was thinking aloud suddenly results in says. 盯着黑板上一行行简洁的算式,陆舟忽然自言自语似得开口说道。 „How to explain existence of Mass Gap with the mathematical linguistics?” “如何用数学语言解释质量间隙的存在？” Hears this issue, opened celebrates gawked subconsciously, immediately became flushed the face, student resulted in likely made excuses some little time. 听到这个问题,张中庆下意识地愣了下,随即涨红了脸,像个学生似得支支吾吾了好一会儿。 „...... This, I really cannot.” “……这个,我真不会。” „I have not asked you, you definitely cannot......” “我没问你,你肯定不会……” Thought aloud that is saying, left behind the mathematical formula of full blackboard, Lu Zhou turned around to leave the classroom, left behind the stunned professor and student. 自言自语地说着,留下了满黑板的算式,陆舟转身离开了教室,留下了一脸错愕的教授和学生。 This issue no one can reply him. 这个问题没有人能回答他。 After all, this is at present in the particle physics most difficult propositions one of the about unified field theory. 毕竟,这可是目前粒子物理中关于统一场论的最难命题之一。 Is the international mathematics circles is also recognized, one of the seven big millennium difficult problems...... 同时也是国际数学界公认的,七大千禧年难题之一……
