Although Lu Zhou does not understand the economics, but in Princeton this place, any division/discipline of studying and math has relations, more or less can have some relations with the person of study math. 虽然陆舟并不了解经济学,但在普林斯顿这种地方,凡是研究和数学扯上了一点关系的学科,或多或少都会和钻研数学的人扯上一些关系。 Especially economic type of thing. 尤其是经济学这种东西。 Either is born the activities of new social product relations or human civilization further expands, otherwise through the traditional fundamental research method, is very difficult to create the novel theory. 要么诞生一种新的社会生产关系或者人类文明的活动范围进一步扩大,否则通过传统的理论研究方法,已经很难在创造出新颖的理论了。 Therefore, wants to make the outstanding research results, the math can be said as only outlet of the modern economists. Although this condition was denounced by the traditional economist to show off the behavior of numbers game, but it truly helped this industry solve the issue of innumerable postgraduate candidate graduation and employment. 因此,想要做出杰出的研究成果,数学可以说是现代经济学家们的唯一的一条出路。虽然这种状况被传统经济学家诟病为卖弄数字游戏的行为,但它确确实实帮助这个行业解决了无数博士生毕业和就业的问题。 In fact, grew in the domain of theory barbarically so many years, the math regarding any computing science is a being too deep to see the bottom mine tunnel, can unearth the valuable thing, all looked the scholar who other domains how utilizes and improves these mathematical instrument that tempers from the innumerable difficult problems, and integrates in it own disciplines and branches. 事实上,在理论的领域野蛮生长了这么多年,数学对于任何计算科学来说都是一座深不见底的矿洞,能不能从中挖掘到有价值的东西,全看其他领域的学者如何去运用并改良那些从无数难题中锤炼出的数学工具,并且将其融入到自己的学科领域中。 Therefore, although Lu Zhou is not interested in the economics specially, but whenever his 3 : 00 pm appears when a cafe in Institute for Advanced Study building, occasionally will then have the professor who is engaged in the economic research chitchatted with him on own initiative, and exchanged to discuss some with him is not that difficult mathematical problem. 因此,虽然陆舟对经济学不是特别感兴趣,但每当他下午 3 点出现在普林斯顿高等研究院一楼的咖啡厅中时,偶尔便会有从事经济学研究的教授主动与他攀谈,并与他交流探讨一些不是那么难的数学问题。 Stayed those years in Princeton, the economic big cow that Lu Zhou has had to do, both hands could not count. 在普林斯顿待了那么些年,陆舟打过交道的经济学大牛,两只手都数不过来了。 Do not say that these have taken the Nobel prize big shot, even «Nature», " Science » quantity withstand/top the editor of publication to relate greatly great with him. 更不要说那些拿过诺贝尔奖的大佬,甚至于就连《Nature》、《Science》量大顶刊的编辑都和他关系不浅。 As long as is the intelligence quotient normal person, will not brave to offend a risk of such big shot, goes to a diploma and degree card of card master's degree student...... 但凡是个智商正常的人,都不会冒着得罪这么一位大佬的风险,去卡一个硕士生的毕业证和学位证…… Why wants this communication author as for Lu Zhou...... 至于陆舟为什么一定要这个通讯作者…… The communication author who he cares about only paper actually not, does not want to make Xiao Tong that teacher occupy him purely to be cheap. 倒不是他在意区区一篇论文的通讯作者,纯粹是不想让小彤的那个导师占他便宜罢了。 Although still some worries, but saw the multipurpose brothers saying that Xiao Tong also no longer insisted, asked after under parents' situation also had good that he crossed recently, then in hungry under the urging of Lu Zhou, made the telephone call longingly. 虽然仍然些担心,但见万能的老哥都这么说了,小彤也就不再坚持,问了下父母们的情况还有他最近过的好不好之后,便在饿得不行了的陆舟的催促之下,恋恋不舍地挂了电话。 After the notebook closes, Lu Zhou that stretches oneself, pulled out cell phone to select to go, then selected the paper that Xiao Tong that has not completed, looked one after another. 将笔记本电脑合上之后,伸了个懒腰的陆舟,掏出手机点了个外卖,然后便点开小彤那篇未完成的论文,一行一行看了起来。 Makes me take a look...... seems like Interesting?” “让我瞧瞧……好像有点意思?” Although the Bewley model he did not understand very much, but has no difference related to the part of math with the mathematical work of elementary student to him. Bewley模型虽然他不是很了解,但涉及到数学的部分对他来说却和小学生的数学作业没什么区别。 After all, how complex model, not possible more complex than the system of plasma turbulence, is more chaos. But even the NS equation and model these two world-class difficult problems of plasma turbulent flow can be solved, only Bewley model, including does not have to the qualifications that he pulls on shoes. 毕竟,无论是多么复杂的模型,也不可能比等离子体湍流的系统更加复杂,更加混沌。而连NS方程和等离子湍流的模型这两个世界级的难题都能够解决,区区一个Bewley模型,连给他提鞋的资格都没有。 Regarding understanding of functional analysis, if he confessed second, no one can call first. 对于泛函分析的理解,若是他自认第二,那没人可以称第一。 However, occasionally pondered some simple issues, have the help regarding his research. 不过,偶尔去思考一些简单的问题,对于他的研究也是存在帮助的。 Goes not to deliver in any case, idles is also idling, using temporarily as was relaxes to be good. 反正外卖还没送过来,闲着也是闲着,权当是放松心情好了。 The right hand pinches the ball pen, the left hand is placing on the keyboard, crossed the material in appendix fast, pinches is ordinary in the wheel that the pen tip of Lu Zhou fingertip seems dances in the air, has ground one skewer of smooth and neat traces from the paper. 右手捏着圆珠笔,左手放在键盘上,快速将附件中的资料过了一遍,捏在陆舟指尖的笔尖就好似飞舞的车轮一般,从纸上碾过一串流畅而工整的痕迹。 Although simple, but before truly is very interesting mathematical problem......, who and I chatted in Princeton? Not was quite a little clear.” “虽然简单了点,但确实是个很有意思的数学问题……以前在普林斯顿的时候谁和我聊过来着?有点儿记不太清了。” Why...... must with the method of Lagrange multipliers to the optimal process in every does one step solve?” When calculates one, the pen tip in Lu Zhou book stopped slightly for several seconds. “……为什么要用拉格朗日乘子法对优化过程中的每一步进行求解?”当计算到某一块的时候,陆舟书中的笔尖略微停顿了几秒。 However, merely is only several seconds. 不过,也仅仅只是几秒钟而已。 Definitely can with the endogenous method of lattice......” think aloud that whispered, Lu Zhou front one line of steps will cross out, wrote down one line of mathematical formulas. “完全可以用内生网格法吧……”自言自语地嘀咕了一句,陆舟将前面的一行步骤划掉,重新写下了一行算式。 Endogenous method of lattice also troubled, optimized the original mathematical model directly, at least can save over 20% tedious operations...... also perhaps is 25%.” “内生网格法也麻烦了点,直接对原数学模型进行优化,至少能节省掉20%以上的繁琐运算……也没准是25%。” This issue is even the difficult problem is really far. 这种问题实在是连难题都谈不上。 The inspiration of spewing out, will shatter shortly kept off in the goal line beforehand city wall. 喷涌而出的灵感,顷刻之间冲垮了挡在终点线之前的城墙。 Wrote down the last line of mathematical formulas, Lu Zhou depended backward on the office chair, pulled down the screen of notebook slightly, making the prerequisite camera aim at own several scratch papers. 写下了最后一行算式,陆舟向后靠在了办公椅上,微微压低了笔记本的屏幕,让前置摄像头对准了自己的几张草稿纸。 Xiao Ai, helping me reorganize.” 小艾,帮我整理一下。” Refers to the Bewley model while convenient, gives my new model to translate a new algorithm to come out.” “顺便参照Bewley模型,给我的新模型编译一个新的算法出来。” Xiao Ai: Receives ~ gave Xiao Ai to be good!( ?)】 小艾:【收到~交给小艾好了!(?)】 Almost and Lu Zhou turns the page the speed to be equally quick, in completed calculating procedure scanning Xiao Ai most in a short time, conducted the reorganization to the entire mathematical model quickly, and possible existing problem or is the slip of the pen and so on place labels, presented in the Lu Zhou front. 几乎和陆舟翻页的速度一样快,在最短时间内完成了计算步骤扫描的小艾,很快对整个数学模型进行了整理,并且将可能存在问题或者是笔误之类的地方标注出来,呈现在了陆舟的面前。 Lu Zhou swept one simply, confirmed after the labelling region does not have the issue, selected toward the computer under. 陆舟只是简单地扫了一眼,确认标注区域没有问题之后,朝着电脑点了下头。 The quick data was uploaded situated in the Jinling Higher Research institute's underground quantum computer, almost after is the data transfer is completed , the short several seconds, the data of feedback then passed from the quantum computer. 很快数据被上传到了位于金陵高等研究院地下的量子计算机中,几乎是数据传输完成之后短短数秒的时间,反馈的数据便从量子计算机那边传了过来。 Xiao Ai: 【The algorithm translation is completed!()】 小艾:【算法编译完成!()】 Xiao Ai: Compares through the Group 12777 piezoelectric intelligent beam examines, improves the mathematical model the numerical computation result and original model basically tallies, the relative dispersion drops 13%, the operation efficiency promotes 21%.?( ^? ^ *)】 小艾:【通过12777组随机参数进行对比检验,改进数学模型的数值计算结果与原模型基本吻合,离散度下降13%,运算效率提升21%。?(^?^*)】 The relative dispersion of computed result means that what he is not very clear, but the operation efficiency promoted 21% basically to conform to his expected result. 计算结果的离散度意味着什么他不是很清楚,不过运算效率提升21%基本上符合了他预期的结果。 The words saying that comes the checking calculation master's thesis with the quantum computer, can plant with the cannon hits the feeling of fly? 话说用量子计算机来验算硕士论文,会不会有种拿大炮打苍蝇的感觉? Ok, does not manage. 算了,不管了。 Who wants him, only then such a younger sister? 谁要他只有这么一个妹妹呢? Let alone now Su Sheng electrical bill not valuable...... 何况现在苏省的电费也不值钱…… Thinks of here, Lu Zhou looked that continued to order to the computer. 想到这里,陆舟看向了电脑继续下令道。 Helps me edit a mail, sent together the algorithm and mathematical model pack.” “帮我编辑一封邮件,把算法和数学模型打包一起发过去好了。” Xiao Ai: Good master!()】 小艾:【好的主人!()】 Sees this skewer of air bubble following face writing, Lu Zhou thinks anything suddenly, then says, right, does not remember stopper your face writing and expression package in the mail, sent normally the mail on the line.” 看到这串气泡后面的颜文字,陆舟忽然想起来什么,接着开口说道,“对了,记得别在邮件里面塞你的颜文字和表情包,正常地把邮件发出去就行了。” Xiao Ai: SIGMA( ° д ° ;) 小艾:【Σ(っ°Д°;)っ】 Lu Zhou: „......?” 陆舟:“……?” Actually although is not very clear Xiao Ai this expression wants to express what meaning, but Lu Zhou does not hope that because of several face writing or the off-line expression packages, destroyed itself big charming intelligent reliable elder brother's the image in the younger sister mind. 虽然不是很明白小艾这个表情究竟是想表达什么意思,但陆舟并不希望因为几个颜文字或脱线的表情包,破坏了自己在妹妹心目中高大帅气聪明可靠的哥哥的形象。 The mail sent for almost five minutes. 邮件发出去过了差不多五分钟。 His mailbox then received the reply of Xiao Tong. 他的邮箱便收到了小彤的回信。 Although the mail content is very short, even short to only had three characters...... 虽然邮件内容很短,甚至短到了只有三个字符…… 【???】 【???】 Saw these three question marks, the Lu Zhou corners of the mouth brought back a self-satisfied smile. 看到这三个问号,陆舟嘴角勾起了一丝得意的笑容。 To come, Xiao Tong has not expected, he only used for one hour, so difficulty the issue gave the solution. 想来,小彤是没有料到,他只用了一个小时的时间,就把如此“困难”的问题给解决了吧。 Said, going that this one hour, I selected how has not arrived.” “说起来,这都一个小时了,我点的外卖怎么还没到。” Rubbed the belly, Lu Zhou took out cell phone, is preparing for delivering meal telephones, actually discovered that own going had been received and signed for before 20 minutes unexpectedly. 揉了揉肚子,陆舟取出了手机,正准备给送餐员打个电话,却发现自己的外卖居然已经在二十分钟前就被签收了。 fuck? 卧槽 Who gave the lead(er) my going? 谁把我的外卖给领了? A moment ago problem solving time extremely invested, he has not noticed the reminder of cell phone. 刚才解题的时候太过投入,以至于他根本就没有注意到手机的提醒。 When a Lu Zhou face compels ignorant, the gate of office noisy three knocks, then saw to carry Wang Peng of pack box to walk. 就在陆舟正一脸懵逼的时候,办公室的门口响了三声敲门声,然后便看见拎着打包盒的王鹏走了进来。 Your yellow Men chicken rice,” will think of the plastic bag of pack box to place on the table, Wang Peng sighed saying that we did hit to discuss the line? You want to eat any me to give you to buy, later can we not select to go, this increases our work difficulties purely.” “你的黄焖鸡米饭,”将装着打包盒的塑料袋放在桌子上,王鹏叹了口气说道,“咱们打个商量行吗?您想吃啥我给您去买,以后咱们能不能别点外卖了,这纯粹是增加我们的工作难度。” Person one hungry was easy to finish up,” put out a hand to take out the pack box from the plastic bag, Lu Zhou smiled embarrassed, „...... said that how was you to deliver.” “人一饿了就容易完事儿,”伸手从塑料袋里取出了打包盒,陆舟不好意思地笑了笑说,“……说起来,怎么是你送上来的。” Wang Peng: I deliver will compare the security.” 王鹏:“我送会比较安全。” Lu Zhou: This meaning is, did my safety level enhance?” 陆舟:“这意思是,我的安全等级又提高了?” Wang Peng hesitated, selected under. 王鹏迟疑了下,点了下头。 Un.” “嗯。” This matter also has nothing to conceal. 这种事情本身也没什么好隐瞒的。 Like the Controlled Nuclear Fusion research was in the critical phase initially the time, the local military region reassigned a even/including directly, is responsible for the security work of his place of residence, adjusted the normal level to the Pangu fusion reactor access electrical network. 就像当初可控聚变研究进入关键阶段的时候,当地军区直接抽调了一个连,负责他居住地的安保工作,一直到盘古聚变堆接入电网才调整到了正常水准。 Now when although did not have the initial Controlled Nuclear Fusion research was so exaggerating, the international form did not have that little while so to be initially stern, but carbon base chip thing is concerning the future of domestic semiconductor industry after all, careful point right. 现在虽然没当初可控聚变研究时那么夸张,国际形式也没当初那会儿那么严峻,但碳基芯片这东西毕竟关乎着国内半导体行业的未来,小心一点还是没错的。 Hears this un, Lu Zhou broke off the hand of chopsticks to stop immediately, looked at Wang Peng one silently. 听到这声“嗯”,陆舟掰开筷子的手顿时停住了,默默地看了王鹏一眼。 When Wang Peng looked by this look is a little bewildered, Lu Zhou coughed to say lightly. 就在王鹏被这眼神看的有点儿莫名其妙的时候,陆舟轻咳了一声开口说道。 „...... Haven't you done that type...... tastes one and so on matter?” “……你没干那种……尝一口之类的事情吧?” Although is far from cleanliness/mysophobia anything, or possibly also truly a little cleanliness/mysophobia...... 虽然谈不上洁癖什么的,或者可能也确实有点儿洁癖…… Only if on the dining table eats meal indifferently, in addition others have touched food, he psychologically in physiology being able to get down mouth. 除非是饭桌上吃饭无所谓,除此之外别人碰过的食物,他无论是心理上还是生理上都是下不去口的。 How possibly?!” By Lu Zhou these words choking, Wang Peng coughed two to recover consciousness, this anything age, which also had to try the poisonous this view. However the hygienic aspect you do not need to worry actually, Dr. face/color has made the simple chemical examination, the hygienic aspect surely does not have the issue.” “怎么可能?!”被陆舟这句话给呛到了,王鹏干咳了两声才缓过来,“这都什么年代了,哪还有试毒这种说法。不过卫生方面你倒是不用担心,颜医生做过简单的化验,卫生方面肯定是没有问题的。” Lu Zhou: „......” 陆舟:“……” MMP! MMP! Originally took my going also to make an chemical examination, I said how to deliver was so slow! 原来是拿着我的外卖还去做了个化验,我说怎么送的这么慢呢! Almost did him to fling a difference to comment backhandedly. 搞得他都差点反手甩一个差评过去了。 But hears Wang Peng this explanation, Lu Zhou was more puzzled immediately. 只不过一听到王鹏这解释,陆舟顿时更纠结了。 Before delivering, unexpectedly crossed the hand of Dr. face/color...... 送过来之前居然过了颜医生的手…… This fellow has the criminal record...... 这家伙可是有前科的啊…… Lu Zhou still remembers, one year ago this goods drink the cola matter secretly. 陆舟依然记得,一年前这货偷喝自己可乐的事情。 It is not right, should say that was the clear(ly) strong past drinks. 不对,应该说是明强过去喝的。 Thinks of here, looks Lu Zhou that goes, is lost in thought. 一想到这里,看着外卖的陆舟,不禁陷入了沉思。 Eats does not eat? 吃还是不吃呢? Really puzzled...... 真是纠结……
