When Lu Zhou arrives in No. 1 lecture hall, the public lecture has started. 当陆舟抵达一号报告厅的时候,报告会已经开始了。 Stands before showing theater curtain ppt, a beard and hair all white old person pushed the eyeglasses on bridge of the nose, the correct use sound spoke the thing that some Lu Zhou cannot be understanding completely at a moderate pace. 站在放映着幕布的ppt前,一位须发皆白的老人推了推鼻梁上的眼镜,正用不紧不慢地声音讲着一些陆舟完全听不懂的东西。 However, although he cannot understand completely, but the scholars under stage actually hear to be very earnest, even is deluded. 不过,虽然他是完全听不懂,但台下的学者们却听得很认真,甚至于如痴如醉。 This made Lu Zhou think about his public lecture actually, whenever he when held the public lecture, the audience under stage basically were also this look, this condition. 这倒是让陆舟想起了他自己的报告会,每当他在开报告会的时候,台下的听众基本上也是这个眼神,这个状态。 Is a expert. 是个高手啊。 Is so thinking at heart, Lu Zhou has not treated in the entrance, quickly looked for a vacancy to sit in the last row of position. 心里如此想着,陆舟没有在门口多待,很快在最后一排的位置找了个空位坐了下来。 In fact, that doctor the view of named Vyse was exaggerating, although the person in lecture hall were truly many, but also was insufficient unable to find and must sit the degree on corridor to a position many. 事实上,那个叫威斯尔的博士的说法还是夸张了点,虽然报告厅里的人确实很多,但还不至于多到一个位置都找不到、必须坐在走廊上的程度。 But few are not many in several people who under the platform sit, basically wears very thick eyeglasses, and appearance very young. This kind of person has the issue or the goal listens to the public lecture, regardless in the lecture hall has the seat, basically sits there. 而寥寥不多在讲台下席地而坐的几个人,也基本上都戴着很厚的眼镜,并且模样非常非常的年轻。这类人都是带着问题或者目的来听报告会的,无论报告厅里有没有位子,基本上都是坐在那里。 After finding the position, Lu Zhou that sat down extended the neck to look at one, later then turned out cell phone, before discovered, that paper that and Xiao Tong cooperated reviewed, while branched out part of energy to listen to two Professor Joseph's explanation. 找到位置之后坐下的陆舟伸着脖子四下望了一眼,随后便翻出了手机,一边找出以前自己和小彤合作的那篇论文回顾,一边分出一部分精力听两句约瑟夫教授的讲解。 the theory of lu-bewley model part, he has basically forgotten. Although this gadget to economic circles as if a little important appearance, but to him, small gadget that also causes conveniently, therefore simply has not put at heart. lu-bewley模型部分的理论,他基本上已经忘了。虽然这玩意儿对经济学界似乎有点重要的样子,但对他自己而言,也就是随手弄出的小玩意儿,因此也根本没有搁在心里头。 However now takes to review the paper, he is quick then the core of paper is the part of mathematical model, successfully picked. 不过现在把论文拿出来重新回顾了一遍,他还是很快便将论文的核心内容即数学模型的部分,给成功地捡了起来。 This keeping one eye on way to people, biggest possibly is two does not flatter, where has not attended. 这种一心二用的方式对于一般人来说,最大的可能就是两头不讨好,哪边都没顾上。 But regarding frequently for Lu Zhou that the time-saving does, he has almost soon been used. 但对于经常为了节省时间而这么干的陆舟而言,他几乎都已经快要习惯了。 Still remembers before , works as that little while of professor in Princeton, not only keeps one eye on, he even can three use wholeheartedly, asked the issue in the hearing time. 还记得以前在普林斯顿当教授的那会儿,不只是一心二用,他甚至能一心三用,在听得时候提出问题来。 Stands on the stage leisure is saying, sees Professor Joseph who wipes the luminous spot from the back row of platform, suddenly knitting the brows head. 站在台上慢条斯理的讲着,从讲台的后排看见一抹光点的约瑟夫教授,忽然皱了皱眉头。 The ray that cell phone screen sends out is actually not obvious, even can say , if not stares toward there specially is looking, may not notice. 那手机屏幕发出的光芒其实并不明显,甚至于可以说如果不是特别往那里盯着看的话,都不一定会注意到。 However, is staring at him in everyone meticulously, was anticipating he in lecture hall that continues to speak downward, a person has actually buried to brush a petty action to the cell phone screen, even if away from is far, even if sat in the last row, in his angle of view still so conspicuous. 然而,在所有人都一丝不苟盯着他,期待着他继续往下讲的报告厅中,一个人却一直埋着头对着手机屏幕刷个不停的小动作,就算是隔着再远、哪怕是坐在了最后一排,在他的视角里也是如此的显眼。 Although plays cell phone at the public lecture is not the rare matter, but he has been very repugnant this behavior, this will make him have an own research results might as well cell phone attractive feeling. 虽然在报告会上玩手机不是什么罕见的事情,但他一直都很反感这种行为,这会让他产生一种自己的研究成果还不如手机有吸引力的感觉。 However, Joseph also knits the brows merely, then disregarded that to make his uncomfortable person. 不过,约瑟夫也仅仅只是皱了皱眉,然后便无视掉了那个令他不爽的人。 If this is in his classroom, he will definitely invite that person who plays cell phone goes out, but here is the academic conference, he impossible, because this small matter loses the time of other scholars, does not have school grades type of thing to be the threat...... 如果这是在他的课堂上,他肯定会请那个玩手机的人出去,但这里是学术报告会,他不可能因为这点小事儿耽误其他学者的时间,更没有学分这种东西能作为威胁…… Lu Zhou at this moment, has not noticed, oneself because of this common movement, were given by some economic big cow unexpectedly repugnantly. 此时此刻的陆舟,并没有注意到,自己竟然因为这个不起眼的动作,被某个经济学大牛给讨厌了。 However if he knows that the reason, will not definitely know whether to laugh or cry to this venerable's eyesight. 不过若是他知道缘由的话,肯定会对这位老先生的眼力哭笑不得。 Let alone feels the conscience to speak, his is not playing cell phone, but reviews the preamble! 更何况摸着良心说话,他这可不是在玩手机,而是回顾前文啊！ However, even if made him know, perhaps Lu Zhou will not care. 不过,就算是让他知道了,陆舟恐怕也不会太放在心上。 First he is not the economic sphere scholar, two arrived at him now this degree, kept thinking about his person 1000 not to have 800, did not miss such a two...... 一来是他又不是经济学领域的学者,二来到了他现在这个程度,惦记着他的人没有一千也有八百了,根本不差那么一个两个…… Read from beginning to end the paper, the part of mathematical model, is the theory part. 将论文从头到尾看了一遍,无论是数学模型的部分,还是理论部分。 Looked that later Lu Zhou received cell phone, was planning how interestingly listens to this Professor Joseph to appraise own mathematical model, the result has not thought that he just focused 看完了之后的陆舟将手机收了起来,正饶有兴趣地打算听听这位约瑟夫教授是如何评价自己的数学模型的,结果没想到他刚刚将注意力放在了台上,这位老先生的下一句话却是差点让他没吐血。 „We know, recently the economic sphere was born a quite novel mathematical model, its creator is well-known Fields rewards winner Professor Lu Zhou, through made the improvement based on classics bewley model, saved massive tedious computations, and makes the result of analog computation more precise......” “我们都知道,最近经济学领域诞生了一个相当新颖的数学模型,它的创作者是知名菲尔茨奖得主陆舟教授,通过在经典的bewley模型的基础上进行了改进,节省了大量繁琐的计算,并且让模型计算的结果更加精确……” „I did not deny that this mathematical model is very attractive , I did not deny.” “我不否认这个数学模型很漂亮,诸位,我并不否认。” Observed the situation lecture hall, Professor Joseph with the serious tone , to continue saying that „, although I am the supporter of new economy trade theory, uses the math as the auxiliary means frequently, assists my quantitative study to economic theory, again what I must result in stress, the math in the economics merely is only the auxiliary means that seems like our is ‚macroeconomic forum’ rather than ‚accountant finance forum’.” 环视了一眼报告厅的现场,约瑟夫教授用严肃的语气,继续说道,“虽然我自己就是新经济贸易理论的支持者,也经常用数学作为辅助工具,来辅助我对经济学理论的量化研究,但我必须得再次强调的是,在经济学中数学仅仅只是辅助工具而已,就好像我们这是‘宏观经济论坛’而不是‘会计金融论坛’。” In the conference site resounded the friendly laughter. 会场内响起了友善的笑声。 Regarding the joke that the venerable plays, many people approve very much. 对于老先生开的这个玩笑,不少人还是很认同的。 Truly, the present new economy scholar relies on the computer more and more, relies on the mathematical instrument more and more, even Nobel economics more and more turns into „Nobel math prize” trend. 确实,现在的新经济学者越来越依赖计算机,越来越依赖数学工具,甚至就连诺贝尔经济学都越来越有变成“诺贝尔数学奖”的趋势。 It looks like in the scholars of conservative faction, this simply was too stupid. 在保守派的学者中看来,这简直是太愚蠢了。 Stopped the moment, Professor Joseph continues to say. 停顿了片刻,约瑟夫教授继续说道。 „The significance of economics is to study the rule of human economic activity, namely the creation of value, transforms the rule that and realizes, rather than numbers game. We are the economists, is not the financial accountant.” “经济学的意义是研究人类经济活动的规律,即价值的创造、转化、实现的规律,而不是数字游戏。我们是经济学家,也不是什么金融会计师。” „This public lecture, although is themed the lu-bewley model, the content that but I then must speak may many disappointed,” deeply looked at a Professor Krugman who sits in the seat near the top, line of sight, in this esteems the lu-bewley model vigorously same stayed for several seconds for the scholar who on rewarded the winner, Joseph continued saying that „I the center of gravity of public lecture, will place to lu-bewley model revelation of shortcoming on.” “这场报告会虽然是以lu-bewley模型为主题,但我接下来要讲的内容或许会让不少人失望,”深深看了一眼坐在靠前座位的克鲁格曼教授,视线在这位大力推崇lu-bewley模型的同为诺奖得主的学者身上停留了几秒,约瑟夫继续说道,“我会将报告会的重心,放在对lu-bewley模型的缺点的揭示上。” „In my opinion, these shortcomings are fatal!” “在我看来,这些缺点是致命的！” Instance that the voice drops, in the lecture hall spread immediately the sound of talking in whispers. 话音落下的瞬间,报告厅里顿时传开了窃窃私语的声音。 Regarding the critique of Professor Joseph, Lu Zhou, although just started almost not to spit blood, but after hearing these contents that behind him said that the expression returned to actually normal. 对于约瑟夫教授的这番批判,陆舟虽然刚开始差点没吐血,但听到他后面说的那些内容之后,表情倒是恢复了正常。 He is a mathematician, to the economic sphere is completely a layman, even if really has the fatal flaw, that is still the indisputable matter. 他本身就是一名数学家,对经济学领域完全是个门外汉,就算真的存在致命的缺陷,那也是无可厚非的事情。 Let alone what this Professor Joseph criticizes is only the economic value of his lu-bewley model, had not said that his mathematical theory is the existing problem. 何况这位约瑟夫教授批判的只是他那个lu-bewley模型的经济学价值,并没有说他的数学理论是存在问题的。 Regarding this Lu Zhou does not care completely. 对此陆舟完全不在意。 Along with him said. 随他说去吧。 When he depended 就在他将后脑勺重新靠回了椅子上的时候,正好听见坐在他旁边的两个模样看起来很年轻,像是在读博士的学者,正小声窃窃私语交流着。 „Professor Krugman did not discuss the lu-bewley model in his new paper? Looked that his attitude is as if opposite with Professor Joseph?” “克鲁格曼教授不是在他的新论文中就讨论了lu-bewley模型的吗？看他的态度似乎和约瑟夫教授正好相反？” „This also with saying! Professor Krugman and Professor Nash's relations have been good! Is the supporter of mathematical economics theory. He most classical viewpoint is, thinks that the exquisite economic model has certainly the aesthetic sense in mathematical significance...... he to seem like the ability in mathematics very general appearance.” “这还用说吗！克鲁格曼教授和纳什教授的关系一直不错！算是数理经济学理论的支持者。他最经典的观点就是,认为优美的经济学模型一定具备着数学意义上的美感……不过他本人好像数学能力很一般的样子。” „This public lecture looked like Interesting.” “这场报告会看来有点意思了。” „Yes, Professor Krugman at the scene! These words of Professor Joseph, perhaps in other words...... he listened a while ago the response of that paper to him who!” “是啊是啊,克鲁格曼教授就在现场吧！约瑟夫教授的这句话,没准就是说给他听的……对他前段时间那篇论文的回应！” „Pitifully, compared with Professor Joseph, the position of Professor Krugman lowered a point! «Economics» author Samuelson, said that feels ashamed of one's inferiority!” “可惜,比起约瑟夫教授来说,克鲁格曼教授的咖位还是低了一点！就连《经济学》的作者萨缪尔森,都表示自愧不如！” Listened to the low voice exchanges of these people, the eyebrow of Lu Zhou to select gently upwardly under. 听着这些人的小声交流,陆舟的眉毛轻轻向上挑了下。 Professor Krugman also in lecture hall? 克鲁格曼教授也在报告厅里？ These words were Joseph said listened specially to him? 这些话是约瑟夫专门说给他听的？ Although does not understand the argument of economic circles very much, but always felt that the matter as if gradually is becoming interesting...... 虽然不是很懂经济学界的争论,但总感觉事情似乎正在渐渐变得有意思起来…… Sits in the lecture hall, the expression of Professor Krugman is somewhat stiff. 坐在报告厅里,克鲁格曼教授的表情有些僵硬。 These words of Professor Joseph, hit his face without doubt. 约瑟夫教授的那些话,无疑是打了他的脸。 Somewhat cannot calm down, Xiao Tong cannot bear finally asks low voice: „Professor, lu-bewley model...... real existing defect?” 有些沉不住气,小彤终于还是忍不住小声问道:“教授,lu-bewley模型……真的存在缺陷吗？” „Did not say,” Professor Krugman shakes the head, „I think was nothing flaw......, but Joseph this old fogy, perhaps he regarding the mathematical model of economics actually compared with my one set, he discovered issue that what I have not discovered also perhaps.” “不好说,”克鲁格曼教授摇了摇头,“我认为是没什么缺陷的……但约瑟夫这老家伙,他对于经济学的数学模型却是比我更有一套,也许他发现了什么我没有发现的问题也说不定。” Andes teaches also nods, approved the view of own old friend Professor Krugman. 安迪斯教授也是点了点头,算是认同了自己的老朋友克鲁格曼教授的说法。 „Also must listen again, perhaps the situation is not bad.” “还得再听听,也许情况没那么糟糕。” Professor Krugman the expression is dignified. 克鲁格曼教授表情凝重。 „Yes, but must listen again.” “是啊,还得再听听。” Professor Joseph on stage continues saying that simultaneously in the floor book of symbol pen with hand in the blank slate in the key part that is explaining once for a while. 台上的约瑟夫教授继续讲着,同时用手中的记号笔在白板上时不时地板书着讲解的重点部分。 „It is well known, bewley model, because overcame the random dynamic general equilibrium frame intrinsic shortcoming, therefore however gradually becomes the mainstream method of macroeconomic study, the lu-bewley model the improvement, for example use endogenous method of lattice ’ and other mathematical instruments, replaced the method of Lagrange multipliers based on this ‚ to the optimal process in every step conducts to solve these to operate tediously......” “众所周知,bewley模型由于克服了随机动态一般均衡框架的内在缺点,因此而逐渐成为宏观经济研究的主流方法,lu-bewley模型在此基础上加以了改进,比如利用‘内生网格法’等诸多数学工具,代替了拉格朗日乘子法对优化过程中的每一步进行求解这些繁琐操作……” „However, this also made the bewley model lose his original rigorous.” “然而,这同时也让bewley模型失去了他本来的严谨性。” 【F ( x , y , z ) = ag 3,1 + bg 3,2 + g 3,3...... x , y , z ≥ 0......】 【f(x,y,z)=ag3，1+bg3，2+g3，3……其中x,y,z≥0……】 【......】 【……】 As his explanation continues to conduct, the mathematical formula also printed one after another in the blank slate. 随着他的讲解持续进行着,一行一行算式也印在了白板上。 Stopped the symbol pen in hand, Professor Joseph then looked to the lecture hall, continued to say. 停下了手中的记号笔,约瑟夫教授回头看向了报告厅,继续说道。 „If introduces the kpr utility function to examine regarding type 3, problem that can in the obvious discovery model have.” “如果对于式三引入kpr效用函数进行检验,可以明显的发现模型中存在的问题。” „A moment ago just like also I said that the lu-bewley model has the fatal flaw theoretically, at least needs to make the large scale revision.” “也正如我刚才所说的,lu-bewley模型在理论上存在着致命的缺陷,至少需要进行大幅度的修改。” „My narration had finished, if there is a question, can raise.” “我的讲述已经结束了,如果有疑问的话,可以提出来。” Conference site completely silent peace. 会场鸦雀无声的安静。 As if a needle falls on the ground can hear. 仿佛一根针落在地上都能听见。 Said these words time, Professor Joseph looked at a direction of Professor Krugman, sees him to look the appearance that a blackboard face compels ignorant, pulled under the corners of the mouth gently. 说这句话的时候,约瑟夫教授看了一眼克鲁格曼教授的方向,见他看着黑板一脸懵逼的样子,不禁轻轻扯了下嘴角。 High under stands sentences. 高下立判。 This fellow has not even kept up with his explanation speed. 这家伙甚至都没跟上他的讲解速度。 Although he had not planned and this fellow compares anything, but esteems the lu-bewley model the view is quite discontented regarding this fellow. 虽然他本来也没打算和这家伙比较什么,只是对于这家伙推崇lu-bewley模型的论调相当不满。 Also thinks this fellow can mention anything, has not thought that an issue cannot ask. 原本还以为这家伙能讲出什么东西来的,没想到连个问题都问不出来。 Thinks of here, on Joseph's face, appeared a light disappointment, and loneliness of several experts. 想到这里,约瑟夫的脸上,浮现了一丝淡淡的失望,以及几丝高手的寂寞。 Can hit does not have! 一个能打的都没有！ In he took the paper to pile on the teacher's desk, prepared to wait a while no one to raise hand again, did not waste the time time, made his unexpected hand, actually lifted from the back row. 就在他拿着论文在讲桌上摞了摞,准备再等一会儿没人举手,就不浪费时间了的时候,一只令他意想不到的手,却是从后排举了起来。 „My a little issue wants to ask.” “我有点问题想问。” As this sound conveys from the back row of lecture hall, big lecture hall, instantaneous lively...... 随着这声音从报告厅的后排传来,偌大的报告厅,瞬间热闹了……
