Chapter 390 Suddenly I had a bad feeling
May passed quickly in a busy month.
Xu Qingzhou consulted materials, read papers, and made calculations every day in order to complete the knowledge of the Riemann hypothesis. At the same time, he also became a househusband for Song Xiaohua, occasionally making a delicious meal for her.
On June 3, Song Yao successfully completed the defense at the Law School. Thus, her undergraduate studies were officially over.
Next, she will participate in the master's and doctoral program jointly organized by Peking University and Harvard.
Everything is in order.
Xu Qingzhou was also able to contact his doctoral supervisor and tell him about his research direction. Unsurprisingly, the 63-year-old man remained silent on the phone for a full half minute.
Of course, although he was surprised, the old man did not object. He just asked Xu Qingzhou to think it over carefully and let him relax during this time.
Song Yao's mentor is Lucille Morton, who hopes that Song Yao will go there in mid-July to participate in the current project.
Like Song Yao, Xu Qingzhou flew from Chengdu to the United States on July 7, transferred in San Francisco, and then flew to Boston to report in advance.
However, before going abroad, the two will go home and stay for half a month.
By mid-June, Xu Qingzhou had almost finished collecting data and planned to test the waters by introducing the Reich metric based on the ideas that came to him while reading the data.
The Reich metric has been used by many scholars as a key tool in research related to the proof of the Riemann hypothesis.
This actually has something to do with Sir Atiyah's proof.
Sir Atiyah used bounded quantities in the physical sense in his proof, but proving the Riemann hypothesis itself involves proving that the Riemann zeta function is bounded, so his proof process is incomplete.
However, using the Reich metric, it may be possible to explicitly prove the boundedness of the Riemann zeta function.
Many people joked that when they saw Sir Theatia, they felt that this proof was hopeless.
Xu Qingzhou thought this thing was quite interesting, so he decided to give it a try, as a test of the waters.
He worked on the proof of the Riemann hypothesis, while Song Yao continued to help Li Dayue's project team.
On June 6, the four people in dormitory 28 gathered together again.
"Mr. Xu, congratulations." Xu Zhengyang and the other two raised their glasses.
Xu Qingzhou smiled and chatted with everyone. Looking at the familiar faces, he felt a little emotional.
After a few drinks, the atmosphere became more lively.
Xu Zhengyang looked at Zhai Ziqiang with gossip: "Old Zhai, you and Zhang Shuyi have such a good relationship, but you don't have any plans to develop further. You will be the only one in our dormitory who will be lonely for four years."
"She and I are just friends." Zhai Ziqiang said embarrassedly.
"嘁~"
The others groaned.
Xu Qingzhou said, "Old Zhai, there's still a year left, maybe we can have a twilight romance."
"What a fucking twilight romance, hahaha."
Kong Xianbo smiled, feeling deeply moved. His former roommates are all going to pursue a doctorate. As for envy and jealousy, it does not exist at all. After all, no one treats them as human beings now.
After chatting for a while, everyone started talking about future plans. Both Kong Xianbo and Zhai Ziqiang planned to continue their postgraduate studies.
Xu Qingzhou looked at Xu Zhengyang and asked with a smile, "Old Xu, you're almost a senior, are you still planning to go out and work?"
Xu Zhengyang nodded and shrugged, "I'm not a good student. I used to think about finishing my four-year undergraduate degree as soon as possible. Now that I've finally graduated, I might as well run."
"If you mention the courtyard house at home again, you will have to drink three cups as punishment," Kong Xianbo reminded.
"Bah~ What's the point of pretending with you guys? Am I the kind of person who likes to show off?"
Xu Zhengyang chuckled twice, paused, and sighed, "It doesn't matter whether I read this book or not. After all, there are two courtyard houses waiting for me to inherit when I return home."
"."
"Come on, Old Xu, have a drink." Xu Qingzhou held up the wine glass.
Kong Xianbo narrowed his eyes and said, "I've discovered a problem. After all the drinking, it seems that only Lao Xu has never been drunk, right?"
"Yeah, no, damn it, this guy has seen our ugly appearance, we can't let him leave standing today no matter what." Xu Zhengyang slapped his thigh.
"Brother Zhou, I toast to you!" Zhai Ziqiang showed his usual silly smile on his face.
Xu Qingzhou thought to himself that this was not good.
"Come on, Lao Xu, let's go too." Xu Zhengyang also came over with a cup.
Although they were clamoring to get Xu Qingzhou drunk, no one went too far. They just started bragging after getting a little tipsy.
Despite this, Xu Qingzhou was outnumbered three at once, and when he came out of the restaurant, his legs felt a little weak, and the other three didn't look much better.
The four of them came to the dormitory building together, and Xu Qingzhou quickly found the cold girl standing under the tree.
Song Yao also saw them, walked over, nodded, and greeted Xu Zhengyang and the other two.
"gone."
Xu Qingzhou held the soft hand and waved to the three people downstairs in the dormitory.
Facing separation, it would be a lie to say that there is no sadness, but Xu Qingzhou also understands that separation is the norm and many people will gradually disappear from life.
"When we graduate, I won't be the last one to leave."
Xu Zhengyang sighed repeatedly, and he could almost imagine how lonely it would be to be alone in the dormitory.
"I don't know when we'll meet next time."
Kong Xianbo also sighed as he looked at the two figures disappearing around the corner.
"There will always be a chance." Xu Zhengyang suppressed his sadness, let out a long breath, cheered himself up, turned around and said, "You two go back, I'm going to find Xiao Chen."
"Brother Yang, why are you still going so late?" Zhai Ziqiang was a little worried.
Xu Zhengyang said: "She's at the school gate."
"Oh, okay, then be careful on the road."
When Xu Zhengyang left again, Kong Xianbo and Zhai Ziqiang appeared at the dormitory door.
"Well, there are only two of us left."
Kong Xianbo was helpless, thinking that it seemed that being in a relationship did have its advantages, at least there was someone to accompany him when he was lonely.
Thinking about it, he shook his head secretly again.
Forget about falling in love. I don’t want to suffer the pain of love. Now is the age for learning and progress. What’s the point of falling in love?
It's good to be alone.
Old Zhai has been single for three years, and he has gotten through it all.
Good brother, I'm with you.
Kong Xianbo turned around and saw Zhai Ziqiang looking at him awkwardly with a silly smile on his face.
Wait, shit, I suddenly have a bad feeling.
Don’t be fooled by Old Zhai’s honest appearance. He is actually a silver-coin expert at killing people and destroying their hearts.
"Um. Brother Bo, I might have to go out for a while."
"."
Kong Xianbo felt as if struck by lightning and stood stiffly in place.
At this moment, just like at that moment.
On the campus path, a young couple was walking slowly, their shadows under the street lights occasionally intertwined.
Xu Qingzhou held Song Yao's hand in his pocket, and suddenly felt that this scene was somewhat familiar. He squeezed Song Yao's hand and said, "I remember that when I was a freshman, I was also drunk, and you came to pick me up."
"Someone is acting like a hooligan." Song Yao said unhappily.
"Yeah~" Xu Qingzhou recalled that time, smiled and said nothing.
Song Yao couldn't help laughing. At that time, she couldn't sleep because of this guy and kept wondering what he meant.
Xu Qingzhou turned around and asked, "Do you want to sit by the lake?"
Song Yao was a little tempted. The closer she was to leaving, the more she wanted to stay here. She was reluctant to leave, but she smelled the alcohol on her boyfriend and said, "You should go back. You've been drinking."
"After blowing for so long, they all woke up."
"Okay." The two turned at the intersection of Jingyuan Road and walked towards Weiming Lake.
The dusk was thick, and there were crowds of people on both sides of the river. The lake was sparkling, and there was the sound of gurgling water. Walking on the embankment, the breeze was blowing gently, and you could smell the scent of moist mud and algae.
"Has Professor Li's work been handed over?"
"Well, Senior Sister Han will be in charge of my part." Song Yao nodded and said, "Professor Li has contacted a senior sister who is studying at Harvard and asked her to help us find a few houses."
"Okay, that will save us a lot of trouble then."
Xu Qingzhou originally planned to stay in the dormitory for a few days after arriving there, and then spend some time to decide on a place to live.
MIT and Harvard are both located in Cambridge, Massachusetts. He has been there several times and is quite familiar with the places. At least he won't get lost.
When Song Yao went abroad to study, the person she was most concerned about, apart from Xu Qingzhou and others around her, was Li Daiyue. Everything was arranged perfectly.
After walking for a while, the two passed by Tzu Chi Temple and found a chair by the lake to sit down.
The shore of Weiming Lake, apart from those reading by the light, is occupied by quite a few couples, the kind that singles would secretly despise when passing by.
Xu Qingzhou closed his eyes and walked outside for a while, but the alcohol had not yet dissipated and he still felt a little tipsy.
The soft little hand restlessly hooked in his palm.
Xu Qingzhou said: "Are you seducing me?"
"I just thought you were asleep."
Song Yao curled her lips.
Xu Qingzhou snorted.
Song Yao looked around and saw that there was no one around. Her eyes darkened and she pounced towards Xu Qingzhou.
"Woo~"
After a while, the two separated, breathing heavily.
Song Yaohuan sat on Xu Qingzhou's lap, her eyes sparkling. This guy just wanted her to take the initiative. So she could take the initiative, it wouldn't be a loss anyway.
Several low voices were heard, and four girls took a shortcut from the small path to the lakeside. They seemed to be from the same dormitory, only seven or eight meters away from Xu Qingzhou and the others.
Moreover, one of the girls raised her chin to signal her companions to look at the kissing couple.
Xu Qingzhou was about to remind everyone that someone was coming, but School Beauty Song lowered her head again.
"."
Damn, I was raped again.
Xu Qingzhou suspected that the girl was actually drunk and that was why she was so aggressive.
However, he noticed that Song Yao's eyes were closed and her soft body was obviously tense.
Haha, stupid Song Yao is starting to try to cover up his mistake.
The four girls' voices suddenly became much quieter, their eyes quickly swept over Xu Qingzhou and Song Yao, then they quickened their pace, and only started talking normally again when they were a little further away.
Song Yao let go of Xu Qingzhou, secretly glanced at the person who just passed by, let out a long breath, patted her hot cheeks, turned around and glared at Xu Qingzhou.
"It's all your fault!"
"?"
The next day, Song Yao went shopping and eating with some of her roommates, while Xu Qingzhou went to say goodbye to some professors.
After coming out from Chu Jiangfeng's side, he turned a corner and went downstairs to Gu Zhizhong's office.
There are three people in the office, and Gu Zhizhong is looking at some documents.
Meng Bin was talking to a strange boy in a low voice, "From this equation, we can see that a(n) is a completely multiplicative function. In order to conveniently apply the Euler product formula, we need to show from the side that ζ(s) absolutely converges in this region. Hey, Junior Brother Xu."
"Senior Brother Meng." Xu Qingzhou greeted with a smile.
This senior fellow graduated with a master's degree this year, and it seems that he will continue his doctoral studies under Professor Gu Zhizhong.
I heard that my former senior brother Su Kewei went to Oxford University.
The boy was stunned at first, then became excited and stood there at a loss as to what to do.
Xu Qingzhou nodded slightly in greeting, then walked towards Gu Zhizhong.
"professor."
Gu Zhizhong took off his reading glasses and looked at Xu Qingzhou. His frowning brows relaxed and he said with a smile, "You haven't left yet. Sit down. Xuanyi, pour some water."
"okay."
The boy wanted to go, but Brother Meng, who was teaching him just now, was faster and said, "I'll do it, I'll do it."
Meng Bin took the lead and skillfully poured the water and handed it to Xu Qingzhou.
"Thank you, senior brother." Xu Qingzhou thanked him sincerely.
"It's my duty to serve tea to the boss." Meng Bin waved his hand and said with a smile. When Senior Brother Su Kewei was around, he couldn't even get the chance to pour water.
Gu Zhizhong smiled and shook his head, then asked, "I heard that you want to challenge the Riemann hypothesis?"
"Well, let's try it." Xu Qingzhou nodded.
Riemann Hypothesis?
Is that the Riemann hypothesis I was thinking of?
Meng Bin stared, feeling like his brain was short-circuiting.
At the side, the new boy also widened his eyes.
"The goals you set are becoming more and more scary."
Gu Zhizhong smiled and said, "If it were someone else, I might have to persuade him to think it over carefully. But as for you, I still say that you should not get stuck in a dead end. Don't be like those people who spend their whole lives on a mathematical conjecture."
"I remember everything you said."
Xu Qingzhou nodded and said.
An expression of admiration appeared on Meng Bin's face, and he secretly sighed that he was worthy of being his junior brother.
They all started with the Riemann hypothesis.
Awesome.
He thought of Professor Gu's ridicule three years ago, saying how embarrassing it would be to be surpassed by this junior fellow.
Is this embarrassing? It's normal to be crushed by a junior fellow student!
Gu Zhizhong nodded with a smile and said no more. This kid always set big goals, but they were really steady, which was completely beyond the mentality of a young man.
"You and classmate Song Yao are both going there. How is the accommodation? You have two senior brothers over there. You can contact them if you need anything."
"Thank you, Professor."
Xu Qingzhou smiled and said, "I've already found a house. It was recommended by Professor Li Daiyue's student. I'll go take a look and rent it if it's suitable."
This is the benefit of connections, there are acquaintances everywhere.
Gu Zhizhong nodded slightly, feeling relieved, and took a sip of tea, sighing: "It's good to go out and have a look. The bigger your horizons are, the bigger the world is. This is especially important for you young people."
It is hard to let go of such a good student, but this is an inevitable process for rapid improvement. Xia Guo is not the best in mathematics. He can only make progress by going out to experience the world and communicating with different geniuses. It is not advisable to work in isolation.
Xu Qingzhou answered yes and looked at the excited boy on the side, "Your new graduate student?"
"Yes, his name is Qin Xuanyi. He has always regarded you as his idol."
"Junior Brother Qin." Xu Qingzhou chuckled and nodded in greeting.
"God Xu!" Qin Xuanyi was excited.
Xu Qingzhou smiled helplessly, thinking that this name was too childish, "You should just call me Senior Brother Xu."
"Senior Brother Xu, please give me your guidance." Qin Xuanyi stood straight.
Gu Zhizhong smiled and shook his head: "Xuan Yi, you really need to learn more from your senior brother. You need to be calm and steady, and change your impetuous habits."
"I understand. I will definitely learn more from you, brother."
Xu Qingzhou stayed in Gu Zhizhong's office for half an hour before going home to continue packing.
