When Lu Zhou looks to this Indian little elder brother, this Indian little elder brother obviously also noticed him. 就在陆舟看向这位印度小哥的时候,这位印度小哥明显也注意到了他。 After Lu Zhou approached, the smiling face that his whole face bathes in fresh air, says with English greeting of curry taste immediately. 当陆舟走近了之后,他满脸如沐春风的笑容,立刻用咖喱味的英语招呼道。 „Hey, the buddy, your vision is good, are you also the theory of numbers direction?” “嘿,哥们儿,你的眼光不错,你也是数论方向的？” „Is. Made the person very much...... the shocking research results,” what understood him to say reluctantly, Lu Zhou read eye that poster, looked around, discovered that periphery and no one was interested the appearance here, then could not bear ask, „why can here no one?” “算是吧。很令人……震惊的研究成果,”勉强听懂了他在说啥,陆舟看了眼那张海报,又四处看了下,发现周围并没有人对这里感兴趣地样子,便忍不住问道,“可为什么这里没人？” „Because of ‚a native of Princeton’ arrogant with prejudice, they are unable to accept a locally born Indian to beat them in the math, even refuses to make me mount the stage preposterously to give a speech. It seems like in ocean one side friend can understand that my mood,” this skin slightly black India little elder brother cracks into a smile, puts out a hand, „lets, Nehru University master's degree student, your name?” “因为‘普林斯顿人’的傲慢与偏见,他们无法接受一个土生土长的印度人在数学上击败了他们,甚至毫无道理地拒绝让我上台作报告。看来还是同在大洋一侧的朋友更能理解我的心情,”这位皮肤略黑的印度小哥咧嘴一笑,伸出手,“迪让,尼赫鲁大学硕士生,你的名字？” Lu Zhou actually wants saying that I am not can understand your mood, because of my research results in fifth day the form display of public lecture, thinks, for does not stimulate this foreign friend, suppressed these words at heart. 陆舟其实想说,我并不是很能理解你的心情,因为我的研究成果将在第五天的以报告会的形式展出,不过想了想,为了不刺激这外国友人,还是将这句话憋在了心里。 „Lu Zhou, Jinling University,” has not proposed own degree, Lu Zhou puts out a hand to grasp grasping with him, then asked impatiently, „I can read your paper?” “陆舟,金陵大学,”没提自己的学位,陆舟伸出手和他握了握,然后便迫不及待问,“我可以看下你的论文吗？” „Paper in this, but I recommend you to look at that gadget,” patted clapped on one pack of papers, lets lose it in side, then carried out a bulk blank slate, wrote to draw above with the symbol pen, „process was a little troublesome, but the principle was very simple, you only needed to listen to me to explain, quick then can understand the mystery of jet braking math.” “论文在这,不过我推荐你看那玩意儿,”拍了拍手上的一叠纸,迪让将其丢在了旁边,然后搬出了一大块白板,用记号笔在上面写写画画了起来,“过程有点麻烦,但原理很简单,你只需要听我讲解一遍,很快便能理解反推数学的奥妙。” „Jet braking math?” The surprise sees this Indian little elder brother, Lu Zhou cannot bear tsukomi say, „you with jet braking mathematical proof? I also think that you study the algebraic number theory.” “反推数学？”诧异地看着这位印度小哥,陆舟忍不住吐槽道,“你是用反推数学证明的？我还以为你是研究代数数论的。” „Algebra is only the tool of research theory of numbers, is not the only way...... I know that these words possibly make you sound a little uncomfortable, after all your Mr. stretch/open for the algebra method showed that the twin prime bounded distance has a good start, but the certificate method that I put out, will mean he not only entered the impasse, but also led one group of mathematicians to enter the tomb together.” “代数只是研究数论的工具,并不是唯一途径……我知道这句话可能让你听起来有点不爽,毕竟你们的张先生为代数方法证明孪生素数有界距离开了个好头,而我拿出的这套证明方法,将意味他不但自己走进了死胡同,还带着一群数学家一起走进了坟墓。” Lu Zhou speechless say/way: „...... I have nothing uncomfortable, can you enter the subject a bit faster?” 陆舟无语道:“……我并没有任何不爽,你能快点进入正题吗？” Let hang the blackboard, then happily selected the eyebrow to Lu Zhou. 迪让将黑板挂了起来,回头对陆舟得意地挑了挑眉毛。 „Immediately good!” “马上就好！” In this Indian little elder brother , in the blank slate writes draws, Lu Zhou notices, many people the interested line of sight will go to here, and approaches toward here. 就在这位印度小哥在白板上写写画画的时候,陆舟注意到,不少人将饶有兴趣的视线投向这边,并且朝着这边靠近过来。 With curious at heart, stands in poster nearby Lu Zhou, looked following this Indian little elder brother's proof line. 怀着好奇的心里,站在海报旁边的陆舟,顺着这位印度小哥的证明思路看了下去。 Actually abstract, his mentality is very simple. 其实抽象来看,他的思路很简单。 First supposed that the twin prime is limited right, and supposes the biggest twin prime to for ( pn-1 , pn ). May know the prime number in pn to be limited, supposing is p1, p2 ... pn-1 and pn. 首先假设孪生素数是有限对,并且设最大的孪生素数对为(pn-1,pn)。可知pn以内的素数是有限的,设为p1、p2...pn-1、pn。 Then constructs big prime number p = ( p1p2p3 * ... * pn ) + 1 然后构造一个大素数p=(p1p2p3*...*pn)+1 Obviously p cannot from p1 to pn all prime number aliquots, forever 1, therefore p is the prime number. But likewise the card, p-2 = ( p1p2p3 * ... * pn )-1 obviously is also the prime number, any was eliminated to the pn prime number from p1 misses 1 forever. 显然p不能被从p1到pn的所有素数整除,永远余一,所以p是素数。同理可证得,p-2=(p1p2p3*...*pn)-1显然也是素数,被任何从p1到pn的素数除永远差一。 Because p is the prime number, p-2 is also the prime number, two constitute a pair of twin prime. 由于p是素数,p-2也是素数,俩个构成一对孪生素数。 Then the issue came, p and twin prime of p-2 constitution is right, „the biggest prime number to” is bigger than of initial establishment, thus denied ( pn , pn-1 ) to be right for the biggest twin prime. 那么问题来了,p和p-2构成的孪生素数对,比最初设置的那个“最大素数对”还要大,从而否定(pn,pn-1)为最大孪生素数对。 Looking like party is the same, regardless of more than ( pn-1 , pn ) big, forever can find ( pn-1 , pn ) bigger prime number is more right. 就像是爬梯子一样,无论(pn-1,pn)多大,永远能找到比(pn-1,pn)更大的素数对。 Thus overthrows in the supposition, „twin prime to is limited” this conclusion, in turn „twin prime to infinite” is right. 从而推翻假设中,“孪生素数对是有限的”这一结论,反过来“孪生素数对无限”便是对的。 The middle process also has, but the overall mentality is this. 中间的过程还有很多,但整体思路就是这样。 Lu Zhou saw the tail him in the process that on the blackboard displayed from the beginning. 陆舟将他在黑板上罗列的过程从头看到了尾。 What accidental/surprised is, he has not quoted any existing research results to solve this problem. 让人意外的是,他没有引用到任何现有的研究成果去解决这个问题。 This jump frame seeks the mentality of answer to be worth advocating. 这种跳出框架寻求答案的思路值得提倡。 However...... 但是…… Lu Zhou understands finally why no one responded him. 陆舟总算是明白,为什么没人搭理他了。 Big prime number p that „you construct, truly can not guarantee from p1 to the pn a series of prime number aliquot, but the prerequisite is pn is the biggest prime number. Clearly, you fell into a logical trap, how you showed that pn is the known biggest prime number?” “你构建的大素数p,确实可以保证不被从p1到pn的一系列素数整除,但前提条件是pn是最大素数。很明显,你掉进了一个逻辑陷阱,你如何证明pn是已知的最大素数？” Makes the eyebrow select: „What you have not seen clearly my first line write is what? In the twin prime to the limited situation, takes ( pn-1 , pn ) of the biggest twin prime to......” 迪让眉毛一挑:“你没看清我第一行写的是什么吗？在孪生素数对有限的情况下,取最大的孪生素数对(pn-1,pn)……” Lu Zhou: „2 * 3 * 5 * 7 * 11 * 13 + 1 = 30031.” 陆舟:“2*3*5*7*11*13+1=30031。” Hears Lu Zhou read this line of mathematical formulas time, in crowd that side surrounded, on the faces of many appeared suddenly, but also some people have obviously guessed correctly, this little while could not have borne smile low voice. 听到陆舟念出这行算式的时候,旁边围观的人群中,不少人的脸上浮现了一丝恍然,还有些人明显早就猜到了,这会儿已经忍不住小声笑了出来。 Also some people...... 还有人…… Is applauding low voice. 小声鼓起了掌。 Let be shocked, felt that some were not right, are frowning to ask: „What do you mean?” 迪让愣住了,感觉有些不对劲,皱着眉头问道:“什么意思？” Lu Zhou sighed: „30031 can dismantle is 59 and products of 5092 prime numbers, therefore this number is Princeton that the divisible number...... you are pay own expenses? Changing me is your professor, will not definitely help you fight for the funds.” 陆舟叹了口气:“30031可以拆解为59和509两个素数的乘积,所以这个数是合数……你是自费来的普林斯顿吗？换我是你的教授,肯定不会帮你争取经费。” Nearby some people blew a whistling. 旁边有人吹了声口哨。 „Ok, please shut up.” “好了,请你闭嘴。” Realized oneself violated preliminarily wrong, the face that lets became flushed the liver colored, tore off the poster crassly, forced in the backpack the thing on table. Nearby some people to his whistle, but he does not pay attention, did not return slides fast. 意识到自己犯了个低级错误,迪让的脸涨红成了猪肝色,骂骂咧咧地一把扯下海报,将桌上的东西塞进背包。旁边有人对他吹口哨,但他毫不理会,头也不回地快速溜了。 Lu Zhou somewhat shrugs reluctantly. 陆舟有些无奈地耸了耸肩。 Actually he also wants to tell this Indian little elder brother, from the angle analysis of mathematical logic, why cannot suppose ( pn-1 , pn ) is the biggest prime number is right, but the Indian little elder brother did not plan opportunity that very much obviously gives him to direct , can only give up. 其实他还想告诉这位印度小哥,从数理逻辑的角度分析,为什么不能设(pn-1,pn)是最大的素数对,不过印度小哥很明显不打算给他指点的机会,也只能作罢了。 Without can look lively, the crowd diverged quickly. 没有热闹可以看,人群很快就散去了。 One person remained, smilingly is visiting him. 只有一个人留了下来,正笑眯眯地看着他这边。 Looks at this, Lu Zhou discovered that somewhat looks familiar. 看着这位,陆舟发现有些眼熟。 Even the clothes have not traded, yesterday led him to find that blonde little elder sister in hotel. 连衣服都没换,正是昨天带他找到酒店的那个金发小姐姐。 Sees Lu Zhou to look to oneself, Morina selected the eyebrow, said: „Did first day get rid of a player?” 见陆舟看向自己这边,莫丽娜挑了挑眉毛,笑着说:“第一天就干掉了一位选手？” Helpless Lu Zhou lets go: „I pointed out his mistake, does make what issue?” 陆舟无奈摊手:“我只是指出他的错误,难道这么做有什么问题吗？” „No, similar matter is performing every time,” Morina bent the curved spit corner/horn, „here, but ‚arrogant’ Princeton, demonstrated here own research results, needed is not only a quick-thinking brain, but must have a carrying capacity enough powerful heart.” “没有,类似的事情每时每刻都在上演,”莫丽娜弯了弯嘴角,“这里可是‘傲慢’的普林斯顿,在这里展示自己的研究成果,需要的不仅仅是一颗思维敏捷的大脑,还得有一颗承受力足够强大的心脏。” Obviously, she heard the tail their dialogues from the beginning. 很显然,她将他们两个人的对话从头听到了尾。 Also is really the wicked interest...... 还真是恶趣味…… Lu Zhou actually has not noticed, when she stands here. 陆舟竟然没注意到,她是什么时候站在这里的。 Sees Lu Zhou not to speak, Morina continues to ask: „Are you mathematical formula that the scene wants to come out? Prepares ahead of time, comes to ambush specially his?” 见陆舟没说话,莫丽娜继续问道:“你是现场想出来的算式？还是提前准备好,专程过来狙击他的？” „Thinks casually, to the talent of Princeton, this should be very simple?” “随便想的,对普林斯顿的天才来说,这应该很简单吧？” Lu Zhou is also all right to this degree bored, he studies the math to not to find fault everywhere. 陆舟还没事无聊到这种程度,他学数学又不是为了到处找茬。 The Morina eyebrow lifted slightly under: „You to talent word possibly has some misunderstandings, the human brain manifest compared with the computer powerful in the logical thinking and creativity, rather than to the operation of floating number. If his topic-based group has under a person who understands a computer, helping his exhaustion method seek for the possible counter-example, he will not run to come to here to make fun from afar.” 莫丽娜眉毛微微抬了下:“你对天才这个单词可能存在一些误解,人脑比计算机的强大体现是在逻辑思维和创造性上,而不是对浮点数的运算。如果他的课题组有一个懂一点计算机的人,帮他穷举法寻找下可能出现的反例,他也就不会千里迢迢跑来这里闹个笑话了。” Lu Zhou: „If no right?” 陆舟:“可是没有如果对吗？” „Yes.” Morina purses the lips to smile, does not know where from fished out chewing gum, „can come one piece?” “是的。”莫丽娜抿嘴微笑,不知从哪摸出了一条口香糖,“要来一片吗？” Hesitant, Lu Zhou put out a hand to extract one piece. 犹豫了下,陆舟伸手抽出了一片。 „Thanks......” “谢谢……” Although some people told him do not accept food of stranger in childhood, but should not have the issue here? 虽然小时候就有人告诉他不要收下陌生人的食物,不过在这里应该没问题吧？ Saw Lu Zhou to accept the chewing gum, Morina pursed the lips to smile. 看到陆舟收下了口香糖,莫丽娜抿嘴微笑。 „Is impolite, since you accepted my small gift, then as the exchange, I hopes that you give me the email and fb account number.” “不客气,既然你收下了我的小礼物,那么作为交换,我希望你把电子邮箱和fb账号给我。” „Email can you, the fb account number I not have...... saying that the custom of which country this is?” “电子邮箱可以给你,fb账号我没有……说起来这是哪个国家的习俗吗？” Told only half, Lu Zhou suddenly has planted by the repertoire the feeling. 说到一半,陆舟忽然有种自己被套路了的感觉。 Morina smiles, said with the joking tone: „No, this is the gentleman demeanor.” 莫丽娜笑了笑,用开玩笑的口吻说:“不,这是绅士风度。”
