Top Student at Their Peak-Chapter 227 - 108: The Future Qiao Yu-Qiao Xi’s Upper Bound Theorem!

The new semester has started, and Yanbei University’s campus has become lively, causing the Mathematics Research Center to become more bustling as well.

Director Tian didn’t lie to him. For instance, some elective courses at the School of Mathematics are conducted directly at the research center. Moreover, the research center also offers a mathematics foundational enhancement class for senior undergraduate students from the School of Mathematics.

Of course, if Qiao Yu wants to attend these courses, he can sit in at any time. Naturally, it’s not just these courses; whether at Yanbei University or Huaqing University, as long as it’s a mathematics course he wants to listen to, he can attend.

No need to bother with online registration for courses, after all, he doesn’t need those credits and grade points for now.

Tian Yanzhen’s request for him in this half-year is still just to finish reading those books.

Qiao Yu also, through actual actions, made Tian Yanzhen realize that he indeed didn’t need to worry too much about this closed-door disciple.

On Sunday night, Qiao Yu would seriously prepare a reading summary and send it to his mentor early on Monday morning. Of course, Qiao Yu also wouldn’t forget to send a copy to his grandpa on Monday morning. Then he would receive two annotated responses.

The annotations on the reading summaries showed that his two mathematics mentors had both conducted in-depth research on these mathematical foundational books. Many details he overlooked would be pointed out to him in the annotations.

During this time, to thank Chen Zhuoyang for his help, Qiao Yu specially invited this senior brother to a big meal at the Huaqing canteen.

Not just because hot water was finally available in the building where he lived, making it possible for him to sneak a shower on the second floor when no one was around at night. More so because the various college entrance exam materials that Senior Brother Chen helped him collect cost Qiao Yu over three hundred for postage alone, including many internal senior high school review papers from the best high schools in Beijing.

Their rarity is self-evident; the teachers who set these papers mostly have experience being selected into the national college entrance exam question setting teams multiple times.

After that big meal, Senior Brother Chen was even more attentive to Qiao Yu.

Because he inadvertently noticed that the balance on Qiao Yu’s Huaqing campus card was slightly terrifying.

Let’s put it this way, if someone stole Qiao Yu’s campus card, the starting penalty for the amount on it would be over ten years. Chen Zhuoyang casually estimated that even if Qiao Yu started eating at the Huaqing canteen from now for thirty years, he might not finish the balance on the card.

Money isn’t everything, but it truly can measure a degree of affection.

The affection from Grandpa Yuan is terrifying, Chen Zhuowen can’t even be envious anymore, only feeling that the gap between people is too vast to compare.

Now he truly believes that if Qiao Yu asked Elder Yuan to help revise his paper, Elder Yuan might personally lend a hand.

Honestly, Chen Zhuoyang also wants to try calling out "Grandpa Yuan" to see.

Unfortunately, there really isn’t an opportunity. Of course, if there were an opportunity, Chen Zhuoyang feels he might not be able to call out loud anyway.

Qiao Yu’s youthful face, compared to his already semi-bald appearance, is really too different. When Qiao Yu calls "grandpa," it evokes a beautiful relationship between grandfather and grandson, but if he called out to his grandpa, he might hold back from throwing up, but who knows what others would think.

Not as talented, and without the advantage of age...

When it comes to mathematics, it’s easy to prove that it’s best to hold on tightly to the junior brother’s leg. A math Ph.D. who doesn’t want to do research has to bow down to graduate, it’s not embarrassing!

On the other hand, although the semester has started and Old Xue is getting busy, he still makes time every day to check on Qiao Yu’s situation.

Sometimes it’s just a visit to see him, sometimes to give Qiao Yu some advice, like helping him plan some courses that are worth attending.

After all, being at Yanbei and not attending classes at all would be too wasteful of resources.

Qiao Yu indeed takes advice well, though he attends fewer classes at the School of Mathematics, whereas he attends more elective courses from the neighboring School of Physics. Mainly focusing on quantum mechanics and methods of mathematical physics.

It’s not because he wants to develop in physics, at least not for now. However, Qiao Yu feels that appropriately broadening his knowledge would be very beneficial for him.

Especially since some concepts in physics can somewhat constrain his tendency to let his thoughts diverge infinitely, after all, physics doesn’t have the freedom that mathematics does.

It is well known that even in mathematical analysis, infinite divergence is quite problematic, as it often means the result cannot be defined. For instance, a diverging series cannot produce a finite sum, directly causing the mathematical model to lose its practical significance.

Besides these regular courses, in the first two weeks after the semester started, Director Tian solved doubts for him twice, and on the opposite side, Grandpa called him over three times.

On one of these occasions, on the same day, Director Tian solved his doubts in the morning, at lunch time, Senior Brother Chen suddenly brought a birthday cake, and Old Xue also came over to deliver a birthday gift.

With a premonition, Qiao Yu was called over by Grandpa in the afternoon, and sure enough, he celebrated his birthday again.

Yes, the first year in Beijing, on February 3rd, the day of his 16th public calendar birthday, Qiao Yu celebrated his birthday twice from noon to evening. At noon at Yanbei University, and in the evening at Huaqing University.

When he returned to Yanbei University in the evening and called Qiao Xi to criticize his mother for not calling him on his birthday, Qiao Xi’s few words snapped him awake: "Are you serious? When have you ever not celebrated your lunar birthday at home? Do I still need to remind you? You already celebrated your birthday once before going to Beijing this year, and Keke even specially ordered a cake for you!"
