In the morning 8 o' clock half, in the lecture amphitheater the position has been filled quickly. 上午八点半,阶梯教室里位置已经快坐满。 Lu Zhou looked for a position in the back row, sits down very much low-key. 陆舟在后排找了个位置,很低调地坐下。 Arrived 8 : 50, lecture amphitheater in full house, but also some people move in the stool from the next door classroom, sits listens on the aisle. 到了8:50,阶梯教室里座无虚席,还有人从隔壁教室搬来凳子,坐在走道上听讲。 Even not only this school, the people in next door several colleges, ran over to rub the class. 甚至不只是本校的,就连隔壁几个院校的人,都跑过来蹭课了。 Can look, the popularity of this Professor Ren Changming is truly big. 看得出来,这位任长明教授的人气确实不小啊。 The 9:00, the course formally starts, sees the venerable on platform, Lu Zhou more looks more looks familiar, always felt that has had casual acquaintance. But separated too, in addition possibly changed clothes, he really cannot think where has seen. 9:00,讲座正式开始,看着讲台上的老先生,陆舟越看越眼熟,总感觉有过一面之缘。但隔得太远,再加上可能换了身衣服,他实在是想不起来在哪里见过了。 PPT starts to show, sits in nearby big elementary school younger sister, stopped and another side roommate finally chirp the speech, puts out a hand in the package to take to write down with the pen. PPT开始放映,坐在旁边的大一小学妹,总算是停止了和另一边的室友叽叽喳喳讲话,伸手去包里拿笔记和笔。 At this time, she saw nearby Lu Zhou, suddenly gawked under. 这时候,她看到旁边的陆舟,忽然愣了下。 Looked at several, she asked low voice: „Schoolmate, are you Lu Zhou?” 多看了几眼,她小声问道:“同学,请问你是陆舟吗？” Lu Zhou gawked, nod: „Yes.” 陆舟愣了下,点头:“是啊。” Female student eyes one bright, the tone asked slightly excitedly low voice: „You...... are you 13 numbers should class of Lu Zhou?” 那女生眼睛一亮,语气略微激动地小声问:“你……您是一三届数应一班的陆舟吗？” „What matter is...... has?” “是……有什么事吗？” „No, all right.” The elementary school younger sister hurries to shake the head to say. “没,没什么事。”小学妹赶紧摇头道。 Is all right you to ask me to do! 没事你叫我干什么！ Lu Zhou is speechless, opens the small book, starts to take the note. 陆舟无语,翻开小本本,开始做笔记。 „......” “……” Lu Zhou: „......” 陆舟:“……” Does not know that is his misconception, always thought that nearby two big elementary school younger sisters are visiting him secretly, but also whispers excitedly low voice, directs the low voice discussion. 不知道是不是他的错觉,总觉得旁边的两个大一小学妹在偷偷看他,还兴奋地小声交头接耳,指指点点小声议论。 Lu Zhou sighed in the heart. 陆舟在心中叹了口气。 This worry as celebrity? 这就是身为名人的烦恼吗？ Feeling...... 感觉…… Also good? 还不错？ Is good has not discussed because of them is too long, the quick topic rushed to other place. 好在她们也没议论太久,很快话题就跑到了别的地方。 Lu Zhou shielded the disturbance automatically, focuses on course. 陆舟则是自动屏蔽了外界的干扰,将注意力集中在了讲座本身上。 Happen, was the professor just to end the prologue, he has not leaked hears a lot of contents. 正好,任教授刚刚结束开场白,他也没漏听到很多内容。 „...... We know, the prime number only includes the natural numbers of two factors, on your possibly Junior High School time has carried the first 100 vegetarian mathematical tables. But the twin prime, refers to the differential value is 2 prime numbers is right, namely p and p + 2 with are right for the prime number. For example 3 and 5, 5 and 7, 11 and 13, 17 and 19. With increasing of number, can the observed twin prime to be getting fewer and fewer.” “……我们都知道,素数是只含有两个因子的自然数,你们可能上初中的时候就背过前一百位的素数表。而孪生素数,是指差值为二的素数对,即p和p+2同为素数对。例如三和五、五和七、11和13、17和19等。随着数的变大,可以观察到的孪生素数对越来越少。” „In 100 has 8 twin primes to be right, but 501 to 600 this sectors, only has 2 pairs. With enlargement of prime number, the next prime number leaves a prime number to be getting more and more far, but also is famous and an important suspicion with the Goldbach's conjecture asserted, exists infinitely many to the prime number, they only differ 2, for example 3 and 5,5 and 7, and even this......” “100以内有八个孪生素数对,而501到600这个区间,只有二对。随着素数的增大,下一个素数离上一个素数应该越来越远,但是与哥德巴赫猜想同样著名和重要的一个猜想断言,存在无穷多对素数,它们只相差二,例如三和5,5和七,乃至这个……” At this point, is the professor on the blackboard, wrote down one line of numbers. 说到这里,任教授在黑板上,写下了一行数字。 【Something went wrong × 2195000-1 and Something went wrong × 2195000 + 1】 【[Not Found]和[Not Found]】 Has turned head, he smiles , to continue to say. 回过头,他笑了笑,继续说道。 „Having the infinite many differential values is 2 prime numbers, this is famous Twin Prime Conjecture.” “存在无穷多个差值为二的素数,这就是著名的孪生素数猜想。” So far, is some shallow knowledge that the professor said that even to the twin prime issue Lu Zhou of deep research, was unable to be very easy to follow. 到目前为止,任教授说的都是些粗浅的知识,即便对孪生素数问题没有过深入研究的陆舟,也能很容易跟上。 Other big new students are also same, no matter the math department is also the amateur of non- math department, is listening interestingly earnestly. 其它的大一新生们也是一样,不管是数学系还是非数学系的业余爱好者,都饶有兴趣地认真听着。 However quick, the content of course started to penetrate. 不过很快,讲座的内容开始深入了起来。 „...... Twin Prime Conjecture, is the difficult problem of puzzle mathematics circles. However last year, in view of the research of this issue, presented the breakthrough progress.” Was the professor to smile, turns the PPT next page, continued saying that „Chinese mathematician, Mr. stretch/open Yitang proved the attenuated form of twin prime, found had the infinite many difference to be smaller than 70 million prime numbers to be right, thus on the path of Twin Prime Conjecture this key issue, made the breakthrough of growing out of nothing.” “……孪生素数猜想,一直是困扰数学界的难题。不过就在去年,针对这一问题的研究,出现了突破性进展。”任教授笑了笑,翻到了PPT的下一页,继续说道,“华裔数学家,张义堂先生证明了孪生素数的一个弱化形式,发现存在无穷多个差小于7000万的素数对,从而在孪生素数猜想这个重要问题的道路上,实现了从无到有的突破。” At this point, was the professor to push the eyeglasses, blackboard writing on blackboard proof process of Mr. stretch/open. 说到这里,任教授推了推眼镜,在黑板上现场板书了张先生的证明过程。 【Defines theta ( n ) = lnn, if n is the prime number ; Defines theta ( n ) = 0, if n is the divisible number. Takes function lambda ( n ) =......, defines S1 ( x ) =......, S2 ( x ) =......】 【定义theta(n)=lnn,如果n为素数;定义theta(n)=0,如果n为合数。取函数lambda(n)=……,定义S1(x)=……,S2(x)=……】 【Tries to prove S2? ( log3x ) S 1 & amp ; gt ; 0......】 【求证S2?(log3x)S1>0……】 【......】 【……】 Looks formula that on that blackboard increases unceasingly, the students who previously can also understand, instantaneous compelled ignorant. 看着那黑板上不断增加的公式,先前还能听懂的学生们,瞬间懵逼了。 For example sits by Lu Zhou that elementary school younger sister, a face „who am I?” „Where am I at?” „I in dictation what?” Expression. Probably missed obviously for one second, what actually the feeling misses is the whole world...... 比如坐在陆舟旁边那位小学妹,一脸“我是谁？”“我在哪？”“我在听写啥？”的表情。就好像明明只是错过了一秒钟,却感觉错过的是整个世界…… Lu Zhou can actually with the mentality of taking office professor. 陆舟倒是能跟上任教授的思路。 Simple, that Mr. stretch/open selected a lambda function ingeniously, successfully proved to k & amp ; gt ; = 3.5 * 10 ^ 6, conclusion S2? ( log3x ) S 1 & amp ; gt ; 0 establishment. 简单的来讲,那位张先生巧妙地选取了一个lambda函数,成功证明了对k>,结论S2?(log3x)S1>0成立。 As the matter stands, before listing , a 3.5 * 10 ^ 6 prime number comes out as the acceptable set row, then can further show, has the infinite many difference to be smaller than 70 million prime numbers to be right. 这样一来,列出将前3.5*10^6个素数作为可接受的集合列出来,便可以进一步证明,存在无穷多个差小于7000万的素数对。 „According to the proof method that Mr. stretch/open leaves behind, by the present, k & amp of Mr. stretch/open ; gt ; = 3.5 * 10 ^ 6, had been reduced k & amp ; gt ; = 50. In other words, 70 million this digits were reduced 246. The remaining work, needed the successor to be completed,” “根据张先生留下的证明方法,截至到现在,张先生的k>,已经被缩小到k>。也就是说,7000万这个数字被缩小到了246。剩下的工作,就需要后来者去完成了,” At this point, is the professor to smile, lost chalk on the teacher's desk, „perhaps, completed this historical work great, will appear among everyone present.” 说到这里,任教授笑了笑,将粉笔头丢在了讲桌上,“也许,完成这一历史性工作的伟大者,会出现在在座的各位中间。” „On the day of I anticipate very much!” “我很期待那天！” pa pa! 啪啪啪！ Bursting into thunderous applause. 掌声雷动。 Under the stage the audience enthusiastically applaud. 台下听众热烈鼓掌。 No matter has understood, at this time followed to applaud is right! 不管听没听懂,这时候跟着鼓掌就对了！ Naturally, many people understood, on the face appeared the thinking deeply expression. 当然了,还是有不少人听懂了的,脸上浮现了深思的表情。 For example Lu Zhou. 比如说陆舟。 Twin Prime Conjecture is only introduction, the course of this half popular science nature is not the academic conference, lies in stimulating the students with emphasis regarding the enthusiasm of math. 孪生素数猜想只是个引子,这种半科普性质的讲座不是学术报告会,重点还是在于激发学生们对于数学的热情。 Was the professor from Twin Prime Conjecture talk about the Goldbach's conjecture, talked about the current home to play the theory of numbers development recent situation from the Goldbach's conjecture, as well as some comparison fronts research results. 任教授从孪生素数猜想讲到了哥德巴赫猜想,又从哥德巴赫猜想谈到了当今国内玩数论发展近况,以及一些比较前沿的研究成果。 Has saying that in this senior professor belly some truly ink. 不得不说,这位老教授肚子里确实有些墨水。 Can some obscure things, the beginner who even spoke still be able to listen with great interest. 能把一些晦涩的东西,讲的即便是初学者也能听的津津有味。 However the content of course latter half, compared with the content of first half, the nutrition was actually short were too many, Lu Zhou has not listened carefully. At this moment, his thoughts also stay above the proof of that Twin Prime Conjecture. 然而讲座后半段的内容,比起前半段的内容,营养却是少了太多,以至于陆舟根本都没怎么仔细听了。此时此刻,他的心思还停留在那个孪生素数猜想的证明上面。 Was recalling previous time the discovery in library, stares on the blackboard Lu Zhou of mathematical formula to deeply frown, during is dark felt that discovered anything, the flash of but always soon holding, making it from referring to the seam sneaks off...... 回想着上次在图书馆中的发现,盯着黑板上算式的陆舟眉头紧锁,冥冥之中感觉发现了些什么,但总是在快要抓住的一瞬间,让它从指缝中溜走…… The course ended quickly. 讲座很快结束了。 The student council person took the list to go to the first row, started to count the registration. 学生会的人拿着名单去了第一排,开始统计签到。 Lu Zhou signs, wants to hurry to the library impatiently, actually sat by him that big elementary school younger sister blocking a moment ago. 陆舟签完到,迫不及待地就想要赶去图书馆,却是被刚才坐他旁边的那个大一小学妹给拦住了。 „Senior, Senior, waits, that can, add your buckle buckle?” “学长,学长,等一下,那个,可以加下你的扣扣吗？” Does not want to waste the time, Lu Zhou one string of press press writes on scratch paper that conveniently, in she handed over, then does not continue to speak the opportunity that to her, in that study younger sister's dumbfounded line of sight, left rapidly. 不想浪费时间,陆舟随手将一串扣扣号写在了她递来的草稿纸上,然后根本不给她继续说话的机会,在那个学妹目瞪口呆的视线中,迅速走掉了。 However just went out, he by a person blocking. 然而刚一出门,他又被一个人给拦住了。 This person is not others, being professor who had the course a moment ago. 这个人不是别人,正是刚才开讲座的任教授。 From the smiling face on that venerable face, he should wait for his a while in the entrance of lecture amphitheater. 从那位老先生脸上的笑容来看,他应该在阶梯教室的门口等了他一会儿。 „Hehe, the young fellow, we met.” “呵呵,小伙子,咱们又见面了。” Lu Zhou:??? 陆舟:？？？ Have we seen? 我们见过？ Where has probably truly seen...... 好像确实在哪里见过…… Has not waited for Lu Zhou to respond, this lets the venerable to continue to open the mouth. 没等陆舟反应过来,这位任老先生又继续开口了。 „Is young fellow, interested in developing toward the rocket on?” “小伙子,有没有兴趣往火箭上发展？” Was just still pondering twin prime Lu Zhou of issue, then by this sudden issue having a scare. 刚还在思考着孪生素数的问题的陆舟,便被这突如其来的问题给吓了一跳。 mother, is this is the astronaut by oneself? 尼玛,这是让自己去当宇航员？ Where this can be good! 这哪能行啊！ Lu Zhou smiles awkwardly: „, Professor, I have not wanted to ascend the sky.” 陆舟尴尬一笑:“呃,教授,我还不想上天。”
