I really just want to be a scholar

Chapter 312 What is Ning Qingyun's gift?
Like most boys, Qin Ke doesn't care much about his birthday.

Of course, it is also difficult for him to forget his birthday, because usually his younger sister Qin Xiaoke's birthday is not long before it is his birthday.

Two weeks ago, he spared one day to go back to his hometown to celebrate his younger sister Qin Xiaoke's birthday. By the way, he bought her the latest fruit mobile phone as a 14 years old birthday present, and asked her to replace the four-year-old mobile phone.

And Qin Xiaoke also gave him Qin Ke's birthday gift in advance that day.

This is a famous brand belt. Qin Ke checked it online, and it actually costs more than 3000...

Qin Ke's whole body, except for the watch that Qin Xiaoke gave him last year, cost less than [-] yuan. Now a belt is more than six times the total price of his clothes, shoes and socks.

Qin Ke originally wanted to "educate" Qin Xiaoke not to spend money recklessly, but after careful observation, Qin Xiaoke really didn't spend money recklessly. He obviously had 40,000 yuan in royalties. In addition to buying some books to learn painting, two Aside from a skirt and a belt for his brother as a birthday present, he didn't even buy comic books or game discs, let alone a new mobile phone.

For this younger sister who has become more sensible, Qin Ke can only rub her hair pityingly, and is reluctant to say half a word.

……

Thanks to Qin Xiaoke's blessing, Qin Ke immediately remembered that his birthday was coming, and he remembered it very much - after all, he had a beautiful and lovely girlfriend this year.

Even the careless Qin Xiaoke remembered to prepare a birthday present for him, let alone the careful Ning Qingyun.

Last year when the two were just friends, Ning Qingyun bought a couple scarf for herself. What about this year?What surprises will there be?
To be honest, Qin Ke is still looking forward to it.

Especially on the afternoon of December 12rd (Friday), when Ning Qingjun suddenly said that he wanted to ask the school for a day off tomorrow, and that he had been asking for leave since the night of the 23rd, Qin Ke couldn't hide his excitement.

Could it be... will there be any additional benefits?

Although considering Ning Qingyun's shy personality, it is unlikely that benefits will be provided, but what if?After all, this is my birthday... Anything is possible!
Qin Ke was full of expectations.

As a result... On the night of the 23rd, Ning Qingyun took him home, had dinner with his grandma Chu Mimei, and then sent him out.

Qin Ke: "???"

That's it?What about benefits?

Qin Ke was disappointed, but still wanted to fight for it: "Jun'er, do you want to go back to Lvcuiyingju to study with me tonight? I think your knowledge of IChO still needs to be consolidated."

Ning Qingyun blushed, and seemed to see his bad intentions: "I want to take a break tonight, and it won't be too late to start the special training for the chemistry competition tomorrow."

Probably feeling a little apologetic, Ning Qingyun shyly kissed Qin Ke outside her house for the first time, and then pushed him outside: "It's getting dark, and the wind is blowing again, I don't know at night Will it snow, you should go back to Lvcuiyingju as soon as possible, let me know when it arrives, and we will contact you on WeChat."

Qin Ke turned his head three times a step, and saw that Ning Qingyun was just standing outside the door and waved at him with a pursed smile, without any intention of changing his mind.

Qin Ke reluctantly gave up.Under the current situation, it is probably not very useful to pretend to be pitiful. After all, grandma is at home, so how could Ning Qingyun stay in Lvcuiyingju for one night?

Look at the sky, it's a bit gloomy, the north wind howls past, shaking the light of the street lamps, and there are even fewer pedestrians on the road.

I hope it won't snow. I want to take Xiaobaicai out to play tomorrow.

Qin Ke hurried back to Lvcuiyingju through the night, and told Ning Qingyun through WeChat, and Ning Qingyun replied: "Then you have a good rest, I will accompany grandma to watch Peking Opera."

Um?Something's wrong, even if you watch Peking Opera with grandma, it doesn't prevent you from sending me WeChat messages. What's the matter with this attitude of forcibly interrupting the topic?

Qin Ke has neither clairvoyance nor binoculars, so he can't see what his girlfriend is doing at home, so he can only guess out of thin air what Ning Qingyun is planning.

Mysterious, could it be related to my birthday present?

The more Qin Ke thought about it, the more he felt it was possible, but since Xiaobaicai wanted to surprise him, he didn't need to guess wildly, just wait for the surprise with peace of mind.

Qin Ke restrained his mind, hummed a nursery rhyme, and after cleaning, he lay down comfortably on the sofa.

Today and tomorrow, he plans to take a holiday for himself, and put aside the matter of the Lime operating system for the time being. After all, it has been optimized to a great extent now. If it wasn’t for Principal Wen Jianzhao’s help with the copyright registration of software copyrights, it wouldn’t be right to release it now. no.

Let's watch my favorite math tonight to relieve boredom.

Qin Ke took out Shi Cunyuan's old mathematics notebook on Riemann's conjecture from his schoolbag, and read it carefully with relish.

This is not the first time he has read this math notebook, and every time he reads it carefully, he has a new experience.

When it comes to Riemann's conjecture, I believe that people who like mathematics will be familiar with it. Although it is not as famous as the famous Goldbach's conjecture, in fact it has a higher status in mathematics than Goldbach's conjecture.

This is a mathematical conjecture about prime numbers.

The so-called prime number, also called a prime number, refers to a number greater than 1 that cannot be divisible by other natural numbers except 1 and itself, such as 2, 3, 5, 7, 11, 13...

After the birth of the concept of prime numbers, the mathematical community believed for a long time that there was no simple law to follow in the distribution of all prime numbers, and some even asserted that prime numbers were irregular.

Until more than 160 years ago, the great German mathematician Bernhard Riemann proposed the famous "Riemann Hypothesis" in an eight-page paper on the distribution of prime numbers: the frequency of prime numbers is related to the Riemann ζ (pronounced zeta) function is closely related, and all prime numbers can be expressed according to a certain law by this zeta function.

以数学语言来描述，则是：“黎曼ζ函数ζ（s）非平凡零点（在此情况下是指s不为-2、-4、-6等点的值）的实数部份是1/2。即所有非平凡零点都应该位于直线1/2 + ti（“临界线”（critical line））上。t为一实数，而i为虚数的基本单位。”

This is the Riemann hypothesis, also known as the Riemann conjecture. So far no one in the world has proved that this conjecture is true, but it does not prevent it from being applied to many fields of mathematics under the assumption that it is true.

For example, many problems in function theory, analytic number theory, and algebraic number theory rely on the Riemann Hypothesis.

According to statistics, in the academic literature of modern mathematics, there are more than 1000 mathematical propositions based on the establishment of the Riemann Hypothesis (or its extended form).If the Riemann Hypothesis is proved, the more than 1000 mathematical propositions will be automatically upgraded to theorems; on the contrary, if the Riemann Hypothesis is disproved, at least half of the more than 1000 mathematical propositions will be invalid.

Because of its importance in mathematical theory, Clay Mathematics Research in the United States did not hesitate to list it as one of the world's seven major mathematical problems for rewards.Whoever proves the Riemann Hypothesis will receive a $100 million reward.

To prove the Riemann Hypothesis, one must first understand its core Riemann zeta function: ζ(s)=Σn^-1 (re(s)>1).

Shi Cunyuan has the complete translation of the eight-page Riemann prime number thesis in his notebook, and he also has a deep understanding of this Riemann function. Then he chose several directions to launch a general attack on the Riemann conjecture, including the Riemann zeta function. Null distribution assumption.

With Qin Ke's mathematics level of half a professional level at this time, it is a bit difficult to see Shi Cunyuan's mathematics notes, which shows how in-depth Shi Cunyuan's research on Riemann's conjecture was at that time.

Someone once said that mathematics is like a very arrogant goddess. It is not because you put in effort and sincerity that she will favor you. The biggest possibility is that you exhausted your energy and ended up with nothing. Did not touch.

Shi Cunyuan is like this.

In the end, Shi Cunyuan found that his several directions were all wrong, wasting a few years of youth in vain, and then he realized that he knew that manpower was limited and talent was limited, even if he was extremely poor, he would not be able to solve such a world math problem.So he gave up this world-class problem, and finally turned to teaching and educating people, passing on the torch.

Now this research result of his research on the wrong path for several years has been passed on to Qin Ke. Qin Ke must first thoroughly understand it and understand where it is wrong before he can find the right direction.

Of course, Qin Ke still has self-knowledge. With his professional level of mathematics, it is impossible to prove the Riemann conjecture. Only when he is promoted to the master level or even the master level can he be more confident.After all, mathematicians in history have continued to work hard for centuries, but have failed to achieve satisfactory results.

But this does not prevent Qin Ke from conducting in-depth research on this and writing a paper with great academic depth.

After two full hours of indulging in the world of mathematics, Qin Ke managed to understand one-tenth of the entire notebook.

"This Chinese translation of Riemann's prime number thesis, I wonder if there is any idea of ​​translating Riemann wrong?" Qin Ke stretched and sat up.

If you want to truly understand the thinking of the original author, the best way is to read the original version. Unfortunately, he does not understand German, so reading the original version is useless.

I don't know if other language subjects will be opened after the system's English subject is promoted to the top "special eight"?Such as German, French, Spanish, etc... After all, scientists come from all over the world, and any translation of their works will have a certain degree of distortion.

Qin Ke took out his mobile phone to check WeChat while muttering, but Ning Qingyun hadn't contacted him.

Qin Ke became more and more convinced that this girl was busy with something, and it must be related to his birthday, which made Qin Ke look forward to tomorrow even more.

After lying down for so long, his body became stiff. Qin Ke pushed open the sliding glass door of the hall and came to the balcony. The cold north wind blew in and refreshed him.

The space on the balcony is not too big, but it is more than enough for a set of Wing Chun. After all, it is a small and delicate kung fu.

So Qin Ke immediately decided to do a set of Wing Chun to stretch his body and activate his blood.

Qin Ke had learned his family's Wing Chun from his classmate Xiang Qi before, but the Wing Chun passed to him by the system was somewhat different from it, probably because the branches were different, and Qin Ke hadn't studied it either.

For him, Wing Chun is more interesting than Tai Chi, and that's enough.

After Xiaoniantou, Xunqiao, Biaozhi, and the wooden dummy pile method were played smoothly, Qin Ke was slightly sweating and felt refreshed. In fact, the professional-level Wing Chun boxing passed to him by the system also included the six-and-a-half stick method and the butterfly double. A knife, but he has no weapons, and such a long stick and double-edged swords are not needed in this society, so he didn't practice.

Anyway, it is produced by the system and will never be forgotten. Even if he does not practice for 20 or [-] years, he can still perform it handily when needed.

After practicing boxing again, Qin Ke, who was sweating all over, went to take a shower before going back to bed and lying down. The pointer of the time was about to point to midnight.

Just after midnight, the WeChat message finally rang.

The little green bamboo will grow taller: "Qin Xiaoke, I wish you a happy birthday!"

A very simple sentence, but it was sent at 00:00 on time. Obviously, the girl has been stuck in time.

The corner of Qin Ke's mouth curled up, and he was convinced of his guess again. Even sending this happy birthday was so carefully clicked, so what would Ning Qingyun's gift be?

　Thanks to "North Latitude 37" for the reward!
