The school year has started, and the campus of Yanbei University has begun to become lively, and even the Mathematics Research Center has become more lively.

Director Tian didn't lie to him when he said that, for example, some elective courses in the School of Mathematics are directly related to research. Moreover, the research center has also specially opened an intensive basic mathematics course for senior undergraduates in the School of Mathematics.

Of course, if Qiao Yu wants to go to these courses, he can also attend them at any time. Of course, it is not just these courses. Whether it is Yanbei University or Huaqing University, as long as it is a mathematics course, he can attend it as long as he wants to. . There is no need to go through the trouble of registering online to take classes. Anyway, he doesn’t need those credits and grade points for the time being.

Tian Yanzhen's request for him in the past six months is still that he only needs to finish reading those books.

Qiao Yu also used practical actions to make Tian Yanzhen feel that he did not need to worry too much about his closed disciple.

On Sunday night, Qiao Yu will carefully prepare a copy of his reading experience, and then send it to his tutor early on Monday morning. Of course, Qiao Yu will not forget to send one copy to his master's grandfather on Monday morning. Then he will receive two comments. From then on. It can be seen from the annotations on his reading experience that his two mathematics tutors have done in-depth research on these basic mathematics books. Many details that he has not noticed will be reminded in the annotations.

In order to thank Chen Zhuoyang for his help during this period, Qiao Yu specially invited this senior Chen to have a big meal in Huaqing's cafeteria.

Not only because the small building he lives in finally has hot water, but it even allows him to secretly run to the second floor to take a shower at night when no one is around. It is also because Senior Brother Chen helped him collect various college entrance examination teaching aids. The cost of mailing it back alone cost Qiao Yu more than three hundred yuan, including many internal review papers for senior high school subjects from the best high schools in Beijing.

Their scarcity can be explained by the fact that most of the teachers who wrote these papers have the experience of being selected into the national college entrance examination question group many times. After that big meal, Senior Brother Chen also became more attentive to Qiao Yu.

Because he accidentally noticed that the balance in Qiao Yu's Huaqing Card was a little too scary.

Let's put it this way, if someone steals Qiao Yu's card, the amount of money in it will lead to a starting sentence of more than ten years. Chen Zhuoyang did the math casually and concluded that even if Qiao Yu eats three meals a day in the Huaqing cafeteria from now on, In ten years, you may not be able to use up the remaining balance in your card.

Money is not everything, but it can really measure a degree of favor.

The favor from Grandpa Shi is so terrifying that Chen Zhuowen can no longer envy him. He just feels that the gap between people is too big and there is no comparison at all. He now really believes that if Qiao Yu holds his thesis Ask Mr. Yuan to help me change it. Maybe Mr. Yuan will take action himself.

Really, Chen Zhuoyang also wants to find a chance to call Teacher Yuan "Grandpa".

It's a pity that there is really no chance. Of course, if there is a chance, Chen Zhuoyang feels that he may not be able to shout out.

The difference between Qiao Yu's youthful face and his half-bald appearance is really big. When Qiao Yu calls him Grandpa, people can feel the beautiful relationship between grandfather and grandson. He calls out Grandpa Shi, I may be able to hold back from vomiting, but I’m not sure what others will think of me.

The talent is not comparable, and there is no age advantage..

In terms of mathematics, it is easy to prove that he should just cling firmly to his younger brother's thigh. A doctor of mathematics who does not want to engage in scientific research lowers his head in order to graduate and does not complain! On the other hand, although school has started, Lao Xue has also started to be busy. Even though I got up, I still took time to check on Qiao Yu every day.

Sometimes I just come to take a look, and sometimes I come to give Qiao Yu some advice, such as helping him plan some courses that he needs to attend every day. After all, I am in Yanbei, and it would be a waste of resources not to attend the classes at all.

Qiao Yu did listen to the advice, but there were fewer courses in the School of Mathematics, and more elective courses in the School of Physics next door. They were mainly concentrated on the two courses of quantum mechanics and mathematical physics methods. Not that Qiao Yu has no plans to develop in the direction of physics, at least for the time being, but Qiao Yu feels that broadening his knowledge appropriately will be beneficial to him.

In particular, some concepts in physics can slightly restrict his infinitely divergent thinking. After all, physics does not have the same degree of freedom as mathematics.

As we all know, even in mathematical analysis, infinite divergence is a headache, because it means that the result may not be defined. For example, the divergence series cannot produce a finite sum, which directly causes the mathematical model to lose its practical meaning. In addition to these daily In addition to the courses, in the two weeks after the school started, Director Tian asked him twice to clarify his doubts, and the teacher from across the street called him three times.

One of them was on the same day. In the morning, Director Tian was helping him solve his doubts. During lunch, Senior Brother Chen suddenly brought a birthday cake, and Lao Xue also came over specially to give a birthday gift. Qiao Yu, who had a premonition, was called over by Senior Senior in the afternoon. , and sure enough, I celebrated his birthday again.

Yes, in the first year of coming to the capital, on February 3rd, Qiao Yu’s sixteenth birthday, he had two birthdays in a row from noon to evening. He spent the noon at Yanbei University and the evening at Huaqing University. Graduated from college.

When he returned to Yanbei University in the evening and called Qiao to criticize his mother for not calling him on his birthday, Qiao Xi scolded him and woke him up with a few words: "Are you sorry? How often have you not been at home? You have a lunar birthday? Do you want me to remind you? You have already celebrated your birthday this year before going to the capital, and I even ordered a cake for you!"

Yes, his birthday on the lunar calendar is on the 29th day of the twelfth lunar month. Because when he was a child, his birthdays were always arranged by his grandfather, and his grandfather only recognized the lunar calendar... So Qiao Yu had three birthdays in the year when he was sixteen.

The other time I was asked by Grandpa Shi to go to the north of Qing Dynasty to send Professor Zhang Shuwen, who had met him once, back to the United States.

It was also at this time that Qiao Yu learned that Professor Zhang was actually a professor and doctoral supervisor at Princeton University. He only had the title of visiting professor in Huaqing. He would come to Huaqing about once or twice a year to complete some agreed lectures. As well as doing some academic exchange activities at Grandpa Shi’s Mathematics Research Center.

In addition, Grandpa Shi also introduced Professor Guo to him. Professor Guo Zhenggong was also a student of his Grandpa. He currently serves as the director of the School of Mathematics at Huahai University. He is Qiao Yu’s senior uncle by seniority. In fact, Qiao Yu has already been online for a long time. I investigated the reasons and process of the conflict between my teacher and my grandfather.

The details on the Internet are not very detailed, but the process is still there. For Qiao Yu, the biggest gain is probably that he discovered that his grandfather, who was usually kind to him, was actually quite fierce when he was young, with a particularly hot temper. However, regarding the things mentioned on the Internet, Qiao Yu felt that it was just a battle of spirits, so he also showed great respect for his uncle.

As Xue Song said, the grudges of the previous generation are not his fault.

Of course, if anyone on both sides sees him uncomfortable, then I'm sorry. Qiao Yu thinks that if he loses his temper, he can actually be quite fierce. Well, he must be as fierce as Grandpa Shi when he was young, and he must learn all the skills.

Fortunately, both Professor Zhang and Professor Guo were quite friendly to him, but at present, Professor Guo mostly did it for Mr. Yuan's sake, and that kind of friendly politeness was often accompanied by a touch of alienation and disdain. Qiao Yu could feel it, but didn't care.

People are not renminbi, and it is impossible to be liked by everyone. It was said in the ethics and rule of law class that the key point is to grasp the main contradiction. The attitude of a senior uncle is irrelevant. On the contrary, Professor Zhang, who was quite strict with him that day, was still quite strict. , but I told him a lot of things, all of which were practical.

His words were full of protection. Before leaving, he also suggested to Qiao Yu that if he was willing, he could go to the Institute for Advanced Study in Princeton as an exchange doctor in a few years to study for one or two years and get in touch with some more advanced foreign students. Mathematical thinking, broaden horizons.

Qiao Yu naturally agreed very well, but he felt that it might have been necessary in the past, but now that he has two major document databases in Yanbei and Huaqing, there is really no need to go out and communicate face-to-face with foreign bigwigs.

In fact, Qiao Yu has always felt that paper communication is more efficient, because high-end papers really don't have so much nonsense, and all the proof processes are clear at a glance. It is enough for him to understand the mathematical ideas of the author of the paper. In short, Qiao Yu feels that his work at Yanbei University Life was still very comfortable.

Most of the time every day is spent reading books and papers, and occasionally going out to attend a few classes. Moreover, this kind of peaceful life is very rewarding.

In terms of learning, Qiao Yu's progress in just two weeks can be said to be very amazing. Yes, it must be described as amazing. After all, it can satisfy both academicians at the same time, and there is a bit of surprise in the joy, which is enough to explain Qiao Yu's learning. How capable he is. Even the two bosses support him to take more classes at the Institute of Physics.

In addition, Qiao Yu discovered through observation that Teacher Lan really did not lie to him. Whether it was Yanbei or Huaqing, there were really few girls in the School of Mathematics and the School of Physics and Astronomy.

Even if there is, it doesn't seem to have caught up with Qiao Yu's aesthetics.

I have nothing to do but go to the nearby Weiming Lake for a walk. You can always see a lot of eye-catching seniors.

It seems that there is a reason why many math people around me, including Teacher Lan, Lao Xue, Senior Brother Chen, etc., are still single at a very young age.

I didn’t have much contact with female classmates, and all of them had to focus on those boring numbers when they were young. It’s strange to have a girlfriend.

The only thing that worries Qiao Yu is probably scientific research. His research on the proposition he proposed before seems to have entered a dead end. What he thought he could show off in front of his mentor and grandpa now seems like

It was like a piece of chicken rib, which made him feel that it was tasteless and a pity to throw away.

But overall, life is quite peaceful and fulfilling. This peaceful and fulfilling life is suddenly disrupted by a group of friends.

Because Qiao Yu has been too lazy to talk in the friend group for a long time, this group of three people has gradually become deserted, and no one has made any comments for a long time. After all, everyone is actually quite busy.

But on Tuesday of the third week of February, that guy Yu Yongjun suddenly started to go crazy in the group @Qiao Yu.

"@蛷 Linfeng Damn it, Damn it, Damn it, the first phase of special training this year is really at Yanbei University! Boss, you are invincible!" "Please, Boss, come out and say something. Let me pay my respects."

Show me your heroic appearance."

"Don't abandon me, boss. You have forgotten that I helped you carry a gun back then, and I also helped you fight against that idiot Yu Wei. Seriously, come out and say whatever you want. Without your instructions,

I can't even breathe!" I have to admit, the little fat guy started running really fast. Within a few minutes, he posted dozens of messages in the group, half of which were @ 青宇.

The direct effect is that the phone vibrates twice after a while.

Unable to bear the disturbance, Qiao Yu finally picked up her phone, quickly scrolled through Yu Yongjun's crazy words, and then sent an angry expression to the group. "Boss, you are finally out!"

"I'm busy! I have to study! I have to do research!" Qiao Yu sent a serious expression wearing sunglasses.

"No, boss, you can't just focus on studying and forget that you still have a life! And we! You immerse yourself in the ocean of knowledge every day and arm your mind with culture. After a long time, in addition to that little knowledge, you also have

What's left?" We haven't seen each other for several months, and this fat man is still the same as before... shameless and irritable.

But don't say it yet, don't say it yet, it will really work...

Qiao Yu obviously felt that these days were very fulfilling, but when the fat man said these words, he suddenly felt that his life was a little bit empty. Yes!

During this period of time, he was so busy studying that he actually forgot that life still needs some simpler and pure happiness. Especially when he was constantly being hit by scientific research projects, he actually forgot that he was also a top student who could hit others.

Yes! Now he spends most of his time studying on his own, and even the joy of hitting his classmates has been temporarily deprived of him.

The most annoying thing is that when you look around you, there are no enemies for the time being, but only friends.

His fellow seniors all took special care of him when they met him. As for his peers..., there seemed to be no peers around him. So he felt unhappy all of a sudden, and the next moment Qiao Yu also started to use his hand speed very quickly.

.

"Don't worry, I'm studying a very important mathematical problem. Do you know Schulz's theory of quasi-complete spaces and the problem of upper bound estimation of rational points on curves? Oh, you definitely don't understand, but it doesn't matter. You just need to know how to put these

The combination of the two will be my recent research topic.

By the time everyone goes to participate in IMO, I will probably be able to conquer this topic. Then you will know that I have not only gained knowledge, but also gained the admiration of the mathematics community and rewards from teachers.

By the way, I may also gain tons of envy, jealousy, and hatred... Well, thinking about it this way, I am actually a little jealous of you two. You live a more fulfilling life than I do, and you don't have to experience the coldness of high places.

Loneliness, but maybe this is the fate of genius."

Yu Yongjun: "!!!" Chan Zhimixue: "???"

Yes, Yu Yongjun sent nearly a hundred messages in the group, but failed to blow up Yu Wei. Qiao Yu directly blew up Yu Wei with just one message. It can be seen that this guy has been peeking at the screen and just refused to come out.

His voice was still as arrogant as usual.

Qiao Yu suddenly felt a little sorry for Yu Wei, because he suddenly thought of Senior Brother Chen. In the field of mathematics, if you are not talented enough, it seems that the longer you persist, the greater the blow you will suffer.

"Huh? Yu Wei, you are here again. I thought you had given up on mathematics. Although discussing IQ is a serious topic, have you ever thought about the possibility that even CMOs cannot get full marks in the exam, so they may not be suitable for studying mathematics?

? (serious face)" Before Yu Wei could reply, Yu Yongjun jumped out first: "Brother, your attack is a bit broad, and it has also hit your most loyal little brother."

Qiao Yu immediately replied: "It's okay. You can learn calculations and mathematics in the future. I've found out everything for you. This thing is very simple. If you can add, subtract, multiply and divide, you can do this. But Yu Wei is different. He

He must be a man who wants to learn algebraic geometry. If you don't believe me, you can ask him, but his IQ may not be enough to study this field.

Oh, by the way, Yu Wei, don’t think too much. I’m not saying you are stupid. In fact, you are quite smart. You are as smart as my brother with a Ph.D. But in this field, smartness is not enough. The requirement for IQ is higher than smartness.

It needs to be higher. For example, your IQ is 160, which is far higher than normal people, but this field requires an IQ of 200, do you understand?"

After posting this, in order to prove his sincerity, Qiao Yu posted another serious expression to the group.

What can I say, after all, he is a brother in the friend group. Qiao Yu really can't stand by and watch a rich second-generation brother choose to jump into the fire pit of mathematics instead of considering going home and inheriting hundreds of millions of assets. But then again

When he came back, he had heard his senior fellow students talk about the lives of many great mathematicians these days. Most of them were really rich second generations, the kind whose families had mines and no shortage of money.

After all, if you get stuck in the research direction of basic mathematics and theoretical mathematics, you may live a lifetime of mediocrity...especially in foreign countries, such as the Earth Science and Technology Center Western University.

A little trivia: Unless you are a particularly well-known scholar at Western University, the salary of professors teaching at Western University is not very high. The median annual income of professors is only more than 80,000 US dollars, and this is pre-tax income.

After personal deductions, after paying taxes in the state of residence, as well as various social security and medical insurance, there is probably only more than 50,000 US dollars left. Calculating the monthly income of less than 5,000 US dollars, it is considered quite poor.

As for associate professors and assistant professors, their salaries are even lower.

Not being famous means that you won't be often invited to give lectures outside, and it will be even harder to get projects.
