Chapter 401 Birthday Wish: Beat Xu Qingzhou Every Day
Xu Qingzhou saw through Song Yao.
He found that it seemed unclear who was the hunter and who was the prey, and they were fishing for each other and then taking the bait.
With a sigh in his heart, Xu Qingzhou followed the principle of cooperating when necessary and asked with a smile, "Do you want to drink something?"
Song Yao handled it very well and said "hmm" in a cold manner.
Xu Qingzhou nodded, but then he remembered that School Beauty Song would have her period at the beginning of the month, so he asked first, "Is there anything wrong with you drinking these days?"
"I'm very good."
Song Yao continued to speak coldly.
"The supermarket is too bad, go buy it outside."
Xu Qingzhou understood immediately, and followed happily behind, pushing the shopping cart.
Song Yao walked in front with brisk steps and her high ponytail swinging back and forth.
Xu Qingzhou stared at the slender figure in front of him, and was shocked. When this girl was aloof, she looked like she was out of touch with the world. Who could have seen the ferocity of her pressing him on the sofa and ravaging him?
Finally, when paying the bill, he took a box of small umbrellas from the side and threw them in.
Tonight is destined to be a bloody battle, so it’s better to take more equipment to be prepared.
The two came out of the supermarket. Xu Qingzhou was carrying two large bags of things. He muttered to Song Yao, "You are obviously very strong."
"I'm a girl." Song Yao held a cup of milk tea.
"In the past, someone could lift a suitcase weighing dozens of kilograms, but now..."
Xu Qingzhou didn't continue talking because his girlfriend had already raised her right hand and made a fist gesture. To be honest, this was not a big deal, she just wanted to tease Song Yao.
Just now she said that she was a weak little girl, but her words broke down.
Song Yao bit the straw and recalled carefully. It seemed that she really became lazier after having a boyfriend. When she was in high school, she did everything by herself.
but.
She has a boyfriend now.
It was impossible before, but now we have this guy
She glanced at the boy next to her.
His expression was calm, he didn't even take a breath, he didn't look tired at all, it was obvious that he was just asking for a beating.
"I want to drink too."
"You just said you didn't want it."
"Just one bite."
Song Yao handed her milk tea to Xu Qingzhou's mouth, and then watched the man take a big sip, and only one third of the milk tea was left in the cup.
"Xu Qingzhou!"
Song Yao stared.
"Gulu~"
Xu Qingzhou swallowed the milk tea and looked at Song Yao innocently: "What's wrong with me?"
"."
At the intersection, the two went to a wine store and bought a bottle of red wine.
6 pm.
The hot pot in the living room was already bubbling with steam.
There was a small four-inch cake next to it.
Light the candles, blow out the candles, and make a wish.
The two of them have a strong sense of ritual.
Xu Qingzhou smiled and asked, "Happy birthday. What's your wish?"
"Our parents are healthy and safe. The second wish, Mr. Xu, I am making this for you."
Song Yao's eyes sparkled when she spoke.
"You made a wish for me?" Xu Qingzhou was touched and couldn't help asking, "What did you make a wish for?"
Song Yao said gently, "Well I hope I can beat you up every day."
"."
"Teacher Song, your second wish is a bit perverted." Xu Qingzhou was speechless. He didn't know what kind of wish this was for him. What was certain was that this girl's wish was definitely not this.
Song Yao snorted softly and cut the cake in half. The four-inch cake was just right for two people. She picked up a piece of cream and licked it, squinting her eyes to feel the happiness brought by the sweetness.
The first wish is true. I hope my parents, Aunt Wang, and Uncle Xu are all in good health.
The second one is very simple, it is just a little girl’s wish, that she and Xu Qingzhou can be together forever.
The two of them were halfway through their meal when they received a call from Song Shisong and Zhang Junli. Seeing that their daughter had both hotpot and cake, the couple felt relieved.
I wished my daughter a happy birthday and hung up the phone without disturbing the two young people's life.
Rongcheng.
Song Shisong put down his phone and turned to look at the family portrait on the wall. "My daughter has grown up."
Nearby, Zhang Junli was looking through photos of her daughter in the group, and she also felt a little surprised that her daughter was already 21 years old.
"21 years old. In another year, I will be old enough to get a marriage certificate." Song Shisong muttered to himself again.
"Yes. Wait a minute, Old Song, your daughter is only 21 years old."
Zhang Junli nodded at first, but soon realized something was wrong. It is unlikely that young people nowadays get married so early.
"That's right, let them plan it themselves." Song Shisong said with a dry cough.
"And she's much more lively than before, which is good now."
Zhang Junli nodded with satisfaction. In the past few years, she was always worried that her daughter was too introverted and would have difficulty finding a boyfriend. Now, she no longer has this worry.
The mother-in-law looks at her son-in-law, and the more she looks at him, the more satisfied she becomes.
Song Shisong had the same idea.
This boy Xu Qingzhou is impeccable in all aspects, and most importantly, my daughter likes him.
After sighing for a while, Song Shisong checked the time on his phone and said, "I won't eat lunch at home."
Because it was more than ten hours earlier than Xu Qingzhou and his team, it was already Sunday morning.
"Huh?" Zhang Junli frowned. She said last night that she would take a day off today?
Seeing his wife's expression change, Song Shisong quickly explained, "Lao Xu said he found a good fishing spot, so I just happened to go check it out today."
Hearing this, Zhang Junli nodded and her frown relaxed. Due to a change in position and his age, her husband has finally not been as busy as before these past few days. He doesn't have to be on the front line of everything like before, so fishing is just right for him to rest and recuperate.
I'm almost an old man, it's time to do some relaxing activities like this.
Boston.
When Xu Qingzhou came out of the shower, Song Yao was chatting with Ding Jiahui on her phone. She said, "The logic of dealing with problems and the learning atmosphere are quite different from those in China. Although I have been here for a short time, I have really learned a lot."
"I'm so envious. Guo Ziyang and I will make some plans and come visit you guys. We haven't even been abroad yet."
"Okay, we'll take you two for a good stroll then."
After Song Yao finished drinking, her pretty face was still flushed. She was still wearing a white camisole today, revealing her two white and slender legs. When she spoke, her legs were bent and folded together.
Seeing Xu Qingzhou coming out, she hugged her legs together to make room for him, and then put her in Xu Qingzhou's arms again.
Xu Qingzhou held Song Yao's legs and listened to the conversation of the two little sisters.
Although it is only the beginning of August, Guo Ziyang and Ding Jiahui have both returned to school, one is busy with a project, and the other is looking for two internships.
"Yeah, I'm also used to the fact that the people I meet so far are all very kind."
Song Yao and Ding Jiahui talked about the people they came into contact with here.
Xu Qingzhou's thoughts drifted away. In his previous life and now, he has spent many years abroad. His biggest feeling is that real discrimination is not some kind of verbal offense, but two words: ignore.
Just pretend you don't exist.
pia~
There was a slapping sound in the living room.
Xu Qingzhou came back to his senses and looked at his hands blankly. He was so excited that his hands unconsciously moved upwards.
Song Yao slapped someone's claws away from her skirt.
Xu Qingzhou touched his hand and sighed: "I'm used to it."
Song Yao gritted her teeth, her boyfriend really deserved a beating!
"Yaoyao, what's that sound?"
Ding Jiahui asked in confusion on the phone. "Nothing."
Song Yao shook her head and continued the topic with Ding Jiahui, chatting about the different customs and cultures of the two countries. After 5 minutes, she hung up the phone.
"Today is a good day." Xu Qingzhou's fingertips stroked across Song Yao's calf.
Song Yao looked up at Xu Qingzhou. As soon as her boyfriend opened his mouth, she could guess what he wanted to say.
"We can have something else, huh?" Xu Qingzhou hinted.
"Xu Qingzhou, it's my birthday, not yours." Although she said this, Song Yao's heart was pounding, and the tension and excitement rushed up again.
If Xu Qingzhou forced himself.
"It's your life."
Xu Qingzhou said as a matter of course: "I'll help you."
"No."
Song Yao looked away, feeling a little guilty.
Xu Qingzhou narrowed his eyes.
creak.
Song Yao was pushed down on the sofa.
"Xu Qingzhou! Um~"
In the corner, Ermao moved his ears, looked up, then lowered his head and lay down to sleep.
After a long time.
Two heavy gasps were heard in the bedroom.
Song Yao's eyes were moist, and her voice was soft and sticky, "Xu Qingzhou, if you dare, I will bite you."
"Hmm~"
12 pm.
Xu Qingzhou was coming out drying his body, and in front of the sink, Song Yao was gargling.
"I have rinsed it four times already."
Xu Qingzhou reminded.
Song Yao turned around and glared at the guy fiercely.
Xu Qingzhou shrugged and looked at the slender figure of Song Xiaohua.
"Xu Qingzhou!"
“It’s still early.”
"."
After a bloody battle, the two men lay down exhausted to rest and did not get up from the bed until 10 o'clock the next day. The next morning, Xu Qingzhou was dragged away and beaten.
12 o'clock noon.
Song Yao's expression was still sour. She looked at the person humming in the distance and wanted to pull him over to beat him up again.
You shouldn't drink and you shouldn't make decisions at night.
Song Yao felt annoyed.
Xu Qingzhou handed a glass of water to Song Yao and said sincerely: "If you really can't figure it out, I'll help you next time."
"."
After pulling Xu Qingzhou aside and ravaging him severely, Song Yao finally felt better.
The two heated up some leftovers from last night and then went about their own business.
Professor Morton gave Song Yao two days off.
The application of discounted cash flow method and real option valuation method.
I have reviewed more than 20 pieces of information in the past two weeks, and I need to write an analysis report almost every week.
Xu Qingzhou seemed to be more relaxed here.
Most doctoral students will choose to work on their supervisor's project. After all, no matter how you look at it, working under a supervisor is the wisest choice, even though it will still be very busy.
But Xu Qingzhou has his own projects and can arrange his time freely.
The teaching assistant work will not start until September.
He now occasionally goes to Professor Roberts to ask questions about math, and the rest of the time he basically spends time in the library reading materials or doing calculations on the Riemann hypothesis.
Two weeks passed.
Every step is difficult.
Although the progress was slow, Xu Qingzhou already had a basic idea of the proof.
First, three proposition inequalities are introduced in the proof.
By coupling the inequalities, it is ideally possible to find that if the Landau-Siegel zero holds, there will be a contradiction.
To put it in simple terms.
For a finite real number sequence χn, how to prove that it is not non-negative?
This is why we need to prove that at least one of the χn will not be less than 0.
To give a simple example, there exists an even number n, and we can now use p(n) to define such a characteristic function.
Here n is a prime number, ρ(n) is equal to 1, otherwise, ρ(n) is equal to 0, thus obtaining a sequence.
In fact, a lot of things in analytic number theory can be reduced to this problem.
In short, in the end, Xu Qingzhou needs to prove that the calculated result is less than 0.
For example, the Goldbach conjecture can eventually be reduced to a sequential order, and we can infer whether there is a number less than 0 in the sequence. If so, the Goldbach conjecture is correct.
Of course, this is only true in theory at present. If it were as simple as Xu Qingzhou thought, the Goldbach conjecture would not have become a century-old problem.
But unfortunately, there is no way to prove that it is less than 0. The most we can do is to find that zn is close to 0. Xu Qingzhou also found that the calculated result will be less than ε multiplied by something.
Even a lot of zn can be found.
These days, Xu Qingzhou plans to use the calculus of variations and the integral equation to find the largest characteristic root.
Although it seems difficult, Xu Qingzhou has a good attitude.
For example.
If the various problems of the Riemann hypothesis that need to be solved are a huge pile of dirt, then the Landau-Siegel zero-point conjecture can be regarded as an excavator. Solving it will increase the speed of demolishing the pile several times.
The weakened version of the Landau-Siegel zero-point conjecture that Xu Qingzhou is working on now is equivalent to a shovel.
Using it to solve the Riemann hypothesis will be very slow, even inefficient, but it is at least some progress.
Monday morning.
As soon as Xu Qingzhou turned on his computer, he saw a new email.
[Xu, I heard that you came to MIT to study. Congratulations. Recently, when I was looking at the data, I found some interesting phenomena, which may be related to undiscovered new particles. If you are interested, we can cooperate.]
[I will be on a business trip to Boston University for 4 days. If you are interested, we may be able to meet.]
The owner of the email is Kunris Richard.
Xu Qingzhou recalled carefully and remembered who this person was: a physics professor at Princeton and a scholar from the French group when he participated in the LHC quantum collider laboratory.
Xu Qingzhou was also invited to study for a doctorate at the École Normale Supérieure in Paris.
Particles.
Xu Qingzhou leaned back in his chair.
Real collision experiment data is open to researchers from all over the world.
The LHC's computer network, which integrates thousands of computers in hundreds of data centers around the world into global computing resources, will facilitate the storage and analysis of the huge amounts of data that the LHC will collect.
So everyone can access it.
Interesting.
The Riemann hypothesis is making slow progress, but I can study something new to relax my brain.
Moreover, studying particle physics really gives me a feeling of exploring the world and grasping the truth of the world.
Thinking about it, Xu Qingzhou opened the email and agreed on a meeting time and place with the other party.
