After receiving the reply of Lu Zhou, Carlson basically does not have any hope, the matter of millennium difficult problem award also put aside. 收到了陆舟的回信之后,卡尔森基本上已经不抱任何希望,千禧难题大奖颁奖的事情也就这么搁置了下来。 Small Said. 说. However, does not know that was who discloses the news, Clay Institute cancelled the original promulgation plan the news to pass on. 然而,也不知道是谁走漏了消息,克雷研究所取消原定颁奖计划的消息就这么传了出去。 Moreover finally passes on is passing on, passed on Lu Zhou to refuse to receive an award. 而且最后传着传着,就传成了陆舟拒绝领奖。 After the ns equation was solved, many media have been paying attention to that about millennium difficult problem 1 million US dollars posting a reward. After all regarding most people who do not pay attention to the math, whether the ns soluation of equation exists is shown, is far from 1 million US dollars having shocking...... 自从ns方程被解决之后,不少媒体一直都在关注着那个关于千禧难题的一百万美元的悬赏。毕竟对于并不关注数学的大多数人来说,ns方程解是否存在被证明,远远没有一百万美元更具冲击性…… New York Times reporter writes to comment. 《纽约时报》记者撰文评论。 【...... Refuses to receive 1 million US dollars posting a reward of after Russian mathematician Perelman, China mathematician Lu Zhou also rejected 1 million US dollars reward. The millennium difficult problem seems lingering a mysterious spell, did the person who unties these propositions, lose finally to the interest of money?】 【……继俄国数学家佩雷尔曼拒绝领取一百万美元的悬赏之后,华国数学家陆舟同样拒绝了一百万美元的奖励。千禧难题仿佛萦绕着一股神秘的魔咒,解开这些命题的人,最终都失去了对金钱的兴趣?】 When received this newspaper from the hand of Hardy, Lu Zhou after looking, then threw into the trash can it conveniently, shakes the head to say. 当从哈迪的手中接过这份报纸,陆舟在看完了之后,便将它随手扔进了垃圾桶,摇头道。 Simply is the utter nonsense, when I had said refuses to receive an award? I make Clay Institute wait, because I am very busy, recently could not find the time to fly again a Paris.” “简直是一派胡言,我什么时候说过拒绝领奖?我只是让克雷研究所等一等,因为我很忙,最近抽不出时间再飞一趟巴黎。” Hardy: Professor, you are because cannot find the time to receive an award, therefore turned down the Clay Institute bonus?” 哈迪:“教授,您是因为抽不出时间去领奖所以才推掉了克雷研究所的奖金吗?” Lu Zhou emphasized said: Postpones.” 陆舟强调了一句说道:“是推迟。” Hardy shrugs reluctantly: Good, postpones...... the professor, actually my some suggestions, but does not know that should say.” 哈迪无奈地耸了耸肩:“好吧,是推迟……教授,其实我有个建议,只是不知道该不该说。” Lu Zhou looked at his one eyes: What suggested?” 陆舟看了他一眼:“什么建议?” Excuse me flexure the back of the head, Hardy said shyly with a smile, I mean, if you really cannot find the time, can send me to go to Paris to receive an award for you. Your research is very busy, but I do not mind one go far from home......” 不好意思地挠了挠后脑勺,哈迪腼腆地笑着说道,“我的意思是,如果您实在抽不出时间,可以派我去巴黎替你领奖。您的研究很忙,但我是不介意出一趟远门的……” Lu Zhou: „......” 陆舟:“……” This fellow...... 这家伙…… Recently was too idle? 最近是不是太闲了? ...... …… About the rumor, regarding Lu Zhou is only a small interlude. 关于外界的传言,对于陆舟而言只是一段小插曲。 He who is busy with the plasma turbulence research, may not have the time to go to what press conference, clarifies this bored matter specially. 正在忙于等离子体湍流研究的他,可没有时间去开个什么新闻发布会,专门去澄清这种无聊的事情。 Besides promulgates this to see the matter, the ns equation to the trouble that he brings and is not only only the excessive attention of media, there are from other aspects. 除了颁奖这见事情之外,ns方程给他带来的麻烦并不仅仅只是媒体的过度关注,也有来自其它方面。 For example, since he leads Fields to reward comes back after Brazil, in his mailbox then crowded the invitation that mails from various places. 比如,自从他带着菲尔茨奖从巴西回来之后,他的邮箱里便塞满了从各种地方寄来的邀请函。 And some from domestic and foreign research agency , some university from mathematical division/discipline global ranking top100, some even at all not from the academic circle, but came from some soap opera dramatic team and some talk-show...... 其中有的是来自国内外研究机构,也有的是来自数学学科全球排名top100的某所大学,更有的甚至根本不是来自学术界,而是来自某个电视剧剧组和某个脱口秀节目…… Throws these mails after entirely Xiao Ai processes, Lu Zhou feels with ease. 将这些邮件统统扔给小艾去处理之后,陆舟感觉轻松了许多。 Mail this in user-friendly rejection as well as on dispose rubbish, Xiao Ai simply like his intimate small cotton-wadded jacket, after he demonstrated several times, now is getting more and more handy. 在人性化的拒绝以及处理垃圾邮件上这点,小艾简直就像他的贴心小棉袄,在他示范了几次之后,现在已经越来越得心应手了。 Arranges after these trivial matters is appropriate, Lu Zhou continues to return to the research work, started the research to plasma turbulence issue. 将这些琐事安排妥当之后,陆舟继续回到了研究工作中,开始了对等离子体湍流问题的研究。 What is worth mentioning is, the difficulty of turbulent flow issue came from two categories of issues mainly. 值得一提的是,湍流问题的困难主要来自于两大类问题。 Complexity that the first kind came from the system and environment, multiplicity of this complex from turbulent motion system. 第一类来自于系统与环境的复杂性,这种复杂性来自湍流运动系统的多样性。 Taking spacecraft for instance, with the flight altitude and speed, even is the region and change of material surface temperature, the spacecraft gas environment and macroscopic mechanical environment constantly changes. 以航天器为例,随着飞行高度、速度、甚至是区域、材料表面温度的变化,航天器所处的气体环境以及宏观力学环境是不断变化的。 As for the second kind of complexity, then originates from the methodology of classical physics. 至于第二类复杂性,则是来源于经典物理的方法论。 The traditional return to original state discussed from most basic component Move out of motion of matter, among interaction rule Move out from basic components established the movement the evolution equation. This sounds like very simple, after all many formulas of classical physics even have no need for the method of advanced mathematics. 传统的还原论都是从物质运动的最基本组元出发,从基本组元之间的相互作用规律出发建立运动的演化方程。这听起来似乎很简单,毕竟经典物理的很多公式甚至连高等数学的方法都用不着。 However in physics, many complex. 然而在物理中,“多既复杂”。 Similarly taking flight vehicle for instance, a Boeing 747 surrounding flow field will contain 10 ^ 15 ~ 10 ^ 24 Microfluidics, makes the dynamical analysis to each Microfluidics, and considered perturbation that creates mutually, even if using completely global all computers, is still very difficult to complete so huge computation load. 同样以飞行器为例,一台波音747周围的流场将包含10^15~10^24个微流元,对每一个微流元做力学分析,并且考虑彼此之间互相造成的扰动,即便是将全球所有计算机全部用上,也很难完成如此庞大的运算量。 All models of researchers who therefore make the Fluid Mechanics analysis mostly, establishes are phenomenological, the different scholars use the similar D method, even can obtain the entirely different result. 所以大多数做流体力学分析的研究人员,所建立的一切模型都是唯像的,不同的学者使用同样的d方法,甚至能得到截然不同的结果。 Also therefore, engineering seal theory -based the turbulent flow D computation, is called art frequently, rather than science. 也正是因此,基于工程化封闭理论的湍流d计算,常常被称为是“艺术”,而非科学。 People study so infatuated regarding smooth and existence of ns soluation of equation, not only and wants to know the solution that cannot seek actually whether exists, but places hopes in the mathematician to be able, when studies this equation, can anything. 人们对于ns方程解的光滑性与存在性研究之所以如此的痴迷,并不仅仅是想知道那个求不出来的解究竟是否存在,而是寄希望于数学家能够在研究这个方程的时候,能够得到点什么。 It perhaps is a computation subsonic area and structure quantity of speed of sound area boundary, perhaps is suitable approximate weak form of one in the limited range, obtains as for Lu Zhou, is the l manifold and processing of differential Geometry method to the partial differential equation. 它也许是一个计算亚音速区和音速区边界的构造量,也许是一个在有限范围内适用的近似弱形式,至于陆舟得到的,则是l流形以及微分几何方法对偏微分方程的处理。 Regarding the Stellarator internal plasma, the first kind of issue said but actually fortunately. Although said that the plasma under high thermobaric condition is unstable, but the mechanical environments of various entire plasma circulation macroscopically components are also at least even. 对于仿星器内部的等离子体来说,第一类问题倒还好说。虽然说处在高温压状态下的等离子体是不稳定,但至少整个等离子体环流在宏观上各组分的力学环境也是均匀的。 As for the second kind of issue, is the core difficult is. 至于第二类问题,则是核心困难的所在。 However, here difficulty also merely regarding average person. 不过,这里的困难也仅仅是对于一般人而已。 When Lu Zhou utilizes in the l manifold the ns equation, and based on the differential Geometry method after these experimental data mathematical modeling, discovers the entire work, although filled complex, but he has not actually imagined is so difficult. 陆舟将l流形运用到ns方程中,并且基于微分几何方法对那些实验数据建立数学模型之后,发现整个工作虽然充满了复杂,但却并没有他想象中的那么困难。 The time passes by day-by-day, the calendar opened the new page. 时间一天天过去,日历翻开了新的一页。 In early September. 九月上旬。 Sits in the office of Princeton Higher Research institute, the Lu Zhou eye will not permit to stare at the computer screen, the pen in hand writes to draw on the paper once for a while. 坐在普林斯顿高等研究所的办公室里,陆舟目不准将地盯着电脑屏幕,手中的笔时不时在纸上写写画画着。 When he knocked the last line of mathematical formulas on the computer, finally long exhales, puts down clamped in the fingertip ball pen. 当他在电脑上敲下了最后一行算式,终于长出了一口气,放下了夹在指尖圆珠笔。 Handles!” “搞定!” Hears the voice of professor, a Hardy face compels to raise the head ignorant, looked at each other one with nearby Qin Yue, then lowers the head silently. 听到教授的声音,哈迪一脸懵逼地抬起头,和旁边的秦岳对视了一眼,然后又默默地低下头去。 Jellicoe and Vera threw the line of sight of worship to Lu Zhou secretly, particularly the latter, in the eye seems glittering the small star. 杰里科和薇拉则是偷偷地向陆舟投来了崇拜的视线,尤其是后者,眼中仿佛闪烁着小星星。 Although does not know that the professor is doing, but always feels very fierce appearance. 虽然不知道教授在干什么,但总觉得很厉害的样子。 As for Wei Wen, is writing the master's thesis, regarding this is aloof. Regarding devoting to this year's graduation will start to read abundant him next year, these things are immaterial. 至于魏文,正在写硕士论文,对此无动于衷。对于有志于今年毕业明年开始读博的他来说,这些事情都是无关紧要的。 In brief, the professor studies any flamboyant thing and that's the end...... 总之,教授又研究出什么牛逼的东西就是了…… Has not noticed students' response, Lu Zhou inspected own mathematical model fast, then the data copy to the USB, having the USB half step to leave the office. 并没有注意到学生们的反应,陆舟将自己的数学模型快速检查了一遍,然后便将数据拷贝到了u盘中,带着u盘快步离开了办公室。 To the inferential reasoning of equation by the work that the human brain then can complete, if related to the solution of value, the computation load of that terrifying then goes beyond the category that the manpower can hope to attain. 对方程的推导是凭借人脑便可以完成的工作,但一旦涉及到数值的求解,那恐怖的计算量便超出了人力所能企及的范畴。 In order to verify his mathematical model, to collect the first-hand simulation data, he needs Super Computer now. 为了验证他的数学模型,同时也为了收集到第一手的模拟数据,他现在需要一台超算 The quicker the better! 越快越好! ...... …… As North American richest university not one, Princeton filthy rich not only manifests, in being willing to spend to dig on the person, manifests to the construction of campus hardware. 作为北美最有钱的大学没有之一,普林斯顿的财大气粗不仅仅只是体现在舍得花钱挖人上,更是体现在对校园硬件设施的建设上。 Although is situated in the Princeton small town of undistinguished appearance, but here has everything expected to find to the Super Computer center from the plasma physics laboratory. 虽然坐落在其貌不扬的普林斯顿小镇,但这里从等离子体物理实验室到超算中心却是应有尽有。 Thus it can be seen, the financially solid alumni association supports in the back, regarding a university how important. 由此可见,有一个财力雄厚的校友会在背后支持,对于一个大学来说是多么的重要。 The school in Princeton with Super Computer, the full title for John Norman supercomputer research center, here mainly makes the coherence physics, the plasma physics and simulator study in celestial mechanics wait aspect. 普林斯顿的校用超算,全称为约翰诺曼超级计算机研究中心,这里主要做凝聚态物理、等离子体物理、天体力学等等方面的模拟研究。 Although in the person of Lu Zhou understanding, there is a David similar this parallel computing domain expert, but the anton strong operational capability only manifests in the computational chemistry domain, the performance in general computation domain is not ideal. 虽然在陆舟认识的人中,有大卫肖这种并行计算领域的牛人,但anton强大的运算能力仅仅体现在计算化学领域,在通用计算领域的表现并不理想。 Let alone David similar, is not necessarily interested in the plasma physics or the Fluid Mechanics simulation, therefore Lu Zhou has not troubled him. 更何况大卫肖本人,对等离子体物理或者流体力学模拟也不一定感兴趣,所以陆舟也就没有麻烦他。 Filled in the application form after Nassau hall, Lu Zhou does not have the waiting to be very long, attained the authorized application of school authorities quickly. 在拿骚堂填写了申请表格之后,陆舟没有等待很久,很快拿到了校方的批准申请。 Any with the research project that the pppl laboratory links up with, the examination is most rapid. 任何与pppl实验室挂钩的研究项目,审批都是最迅速的。 Let alone is a Fields rewards the winner. 更何况是一位菲尔兹奖得主。 Brought the written document to go to John Norman Super Computer center, Lu Zhou found director Amer Professor Green of research center, explained own purpose in coming to him. 带着书面文件来到了约翰诺曼超算中心,陆舟找到了研究中心的主任阿迈尔格林教授,向他说明了自己的来意。 After listening to the request of Lu Zhou, Green's eyebrow selected selecting surprisedly. 听完了陆舟的请求之后,格林的眉毛惊讶地挑了挑。 Unbelievable...... you determined that you haven't cracked a joke? Did you in the plasma turbulence for Stellarator succeed in building the mathematical model?” “难以置信……你确定你没有开玩笑?你为仿星器中等离子体湍流成功建立了数学模型?” Although he is not Physics, but still knows that this is a how astonishing matter. 虽然他不是物理学家,但依然知道这是一件多么惊人的事情。 Lu Zhou sighed, shook the requisition in hand: From fool's day also a half years, I determined that I am not cracking a joke.” 陆舟叹了口气,晃了晃手中的申请书:“距离愚人节还有半年,我确定我不是在开玩笑。” Professor Green rubbish, uses the computer that begins to affect, that model do you bring?” 格林教授没有废话,打开了工作用的电脑,“那个模型你带着吗?” Lent money u on the table, Lu Zhou said: Naturally.” 将u盘放在了桌子上,陆舟说道:“当然。” Received the USB to insert on the computer, after opening inside document, looks at the data and image in computer screen, Green felt beard stuble on chin, pondered over a moment later said that with all due respect, this looked very difficult. I did not determine that our John Norman is capable of withstanding this magnitude operation, you need perhaps is summit of Ridge National Laboratory...... does not have the means this CAD model simplification one?” 接过u盘插在电脑上,打开里面的文件之后,看着电脑屏幕中的数据和图像,格林摸着下巴上的胡渣,思忖了片刻之后说道,“恕我直言,这看起来很难。我不确定我们的约翰诺曼有没有能力承受这种量级的运算,你需要的恐怕是橡树岭国家实验室的summit……就没有办法将这个模型简化一下吗?” Lu Zhou shakes the head: This is most Jane/simple form that I can achieve.” 陆舟摇了摇头:“这已经是我能够做到的最简形式了。” Good, you represent the pppl laboratory to create a Gordian knot to us,” Professor Green is transferring the pen in hand, thought said a moment later, algorithm part I can solve, but, do not count on that this work can be completed in a short time.” “好吧,你代表pppl实验室给我们出了个难题,”格林教授转着手中的笔,思索了片刻之后说道,“算法部分我可以解决,不过,你不要指望这个工作能在短时间内完成。” Lu Zhou nods: I know. Moreover, I will provide the help to you.” 陆舟点头:“我知道。而且,我会向你们提供帮助。” Professor Green said with a smile: This is must, after all we do large-scale parallel computing, is not the plasma physics expert.” 格林教授笑着说道:“这是必须的,毕竟我们是搞大规模并行计算的,可不是等离子体物理专家。”
