Chapter 292 I don’t know who was begging for mercy last night
morning.
When Xu Qingzhou woke up, Song Yao, who usually got up very early, was still sleeping soundly. She seemed to be disturbed by Xu Qingzhou, and she uttered vague mumblings and nudged him again.
He must have been really tired this time, after all, School Beauty Song had used a deadly scissor kick on him last night.
The eldest senior brother locked up He Jinyin, and He Jinyin locked up the eldest senior brother.
Xu Qingzhou put one hand behind his head and enjoyed the quiet morning.
Half an hour passed.
The girl in Xu Qingzhou's arms moved and woke up. He slowly closed his eyes and pretended to be asleep. He was a little curious about the girl's first reaction after waking up.
Song Yao opened her eyes and looked at Xu Qingzhou carefully. She found that he was still sleeping. She couldn't help but breathe a sigh of relief. When she thought of the madness of last night, her face felt hot.
She is such a serious person but was led astray by this bad guy.
After cursing inwardly, Song Yao slowly got up. She had no idea where her clothes had been thrown away. After searching for a long time, she finally found her clothes on the floor at the end of the bed.
All dirty.
She could only get out of bed and look for clean clothes in the closet.
After putting on everything, Song Yao turned around and froze. It turned out that the person who was sleeping soundly just now was looking at her with eyes wide open, with a naked smile in his eyes.
In broad daylight, naked.
Haha, pretending to be cool again.
Xu Qingzhou asked with a smile: "Want to lie down for a while?"
Song Yao said expressionlessly: "It's already 9 o'clock."
"Aren't you tired?" Xu Qingzhou asked with a smile again.
"Are you tired?" Song Yao asked back expressionlessly.
Xu Qingzhou adjusted his sleeping position, put his hands behind his head, and said, "I don't know who was begging for mercy last night. It was wrong, wrong."
The guy with the bad mouth was pinned to the bed and beaten up by Song Yao.
After finishing the content of the exponential sum of Polignac's conjecture, Xu Qingzhou put it aside for the time being and concentrated on his thesis. In mid-October, Professor Gu called and agreed with Xu Qingzhou to have the defense on November 10nd.
So in the following period of time, Xu Qingzhou was busy working on his papers, mainly on the renormalization group theory.
Some have commented that, in effect, the renormalization group is like sweeping a roomful of trash under the carpet without removing it completely.
This makes sense. The starting point of renormalization is the renormalization of the wave function, which seems to be legal. However, when we study renormalization carefully, we will find that renormalization actually redefines the entire field.
It is not studying the original field "just on the facts", but quietly changing the field to study.
Of course, just as Professor Gu told him last time, many things cannot pursue absolute perfection, and the actual value of a research tool cannot be evaluated arbitrarily.
At the very least, the renormalization group is widely used, both in the calculation of quantum field theory and in the currently popular condensed matter physics, which shows that it is quite valuable.
Xu Qingzhou first used path integral to calculate the amplitude and then extrapolated and truncated the normalized coupling constant.
At the same time, the functions inside are modified and new coupling constants are introduced. The set of trajectories generated from different initial parameter values is called the renormalized group flow.
October passed and the day for the defense soon arrived.
8: am.
"Paper, water cup"
Song Yao was muttering to herself as she helped Xu Qingzhou check the things in his bag. She had asked Professor Li Daiyue for leave so that she could accompany Xu Qingzhou to the defense.
Xu Qingzhou was sitting on the sofa peeling an orange. He found that School Beauty Song was even more nervous than himself, the respondent. He smiled and comforted her: "Don't worry, I've brought everything."
As for the defense during my undergraduate studies, I can talk about it with my eyes closed.
Song Yao checked everything before trudging over and snatching away the half-peeled orange that Xu Qingzhou had just peeled.
"After your defense today, you will graduate from your undergraduate program. When you graduate from your master's program next year, you will go study abroad."
"I can wait for you." Xu Qingzhou said that if he went out, he was confident that he could get his diploma in one year. Of course, getting a certificate was relatively simple. The important thing was to get more exposure to cutting-edge mathematical knowledge.
"How can I wait for this?" Song Yao pouted, ate an orange, thought for a while, and said, "If I can graduate early, I can also apply to be an exchange student."
"Professor Li, are you willing to let you go directly?" Song Yao is now Professor Li's treasure. He teaches her everything he knows and keeps her by his side at all times. He wishes to pour all his knowledge into Song Yao's head.
"I'm an exchange student, it's not like I won't be coming back."
Seeing Song Yao finish eating the orange, Xu Qingzhou picked up a freshly washed grape and handed it to her mouth.
Song Yao held a grape in her mouth, bit it, and squinted her eyes because of the sourness, "Hiss~ It's so sour~"
"I was cheated by that big sister. All these grapes are sour." Xu Qingzhou was indignant.
“You know the sour kind?”
Xu Qingzhou nodded: "I just tried two."
"Then give it to me?"
I really want to give this guy two lumps.
But Song Yao still held back. She had begun to doubt whether this guy was happy when being beaten. He knew that he would be beaten by her, but he still enjoyed it. She couldn't let him succeed.
Xu Qingzhou smiled and said, "You can't just be jealous of me."
pia~
So, Xu Qingzhou was hit by Song Yao's Tathagata Palm.
After packing up at home, seeing that it was almost time, the two changed their clothes and prepared to leave.
In November, it was about to snow for the first time in Kyoto. The temperature was low, so both of them changed into thick clothes.
Song Yao was wearing a white sweater, which revealed her slim figure.
Xu Qingzhou leaned against the shoe cabinet, admiring the beautiful figure of School Beauty Song.
Seeing Xu Qingzhou looking at her again, Song Yao zipped up her coat to cover her beautiful body and clenched her fists. This guy is about to defend his thesis, but he is still so nonchalant.
Xu Qingzhou shrugged innocently. He could never get tired of looking at the outfit of School Belle Song.
It was early November and there was still some time before the heating came on, but the house was still much hotter than outside. As soon as I walked out of the building, the cold wind blew into my clothes.
The sun has come out, but it is still a bit cold, and I exhale puffs of hot air.
Xu Qingzhou took one of Song Yao's hands and put it in his pocket. Without stopping, the two of them went straight to the defense classroom.
At 9:40 in the morning, Xu Qingzhou and Song Yao arrived at classroom 2021 of the School of Mathematics on time.
"Brother Tong."
Xu Qingzhou greeted instructor Zhu Sitong.
"Are you ready?" Looking at the boy who walked in, Zhu Sitong felt so emotional. He just entered the school in September last year and graduated in November this year. This speed is unparalleled.
With this kid's achievements, it wouldn't be excessive to directly award him a doctorate degree.
However, there is no precedent for this.
"Well, all right."
Xu Qingzhou nodded slightly.
After greeting Zhu Sitong, he went to the stage to prepare for the defense, while Song Yao went to sit in the corner of the classroom.
March 11, 2 am.
The defense teacher is already in place.
Professor Gu Zhizhong, Academician Wang Lin, and Academician Chu Jiangfeng from the School of Mathematics.
Academician Ma Liangzai, Professor Zhao Shengwen, and Academician Yang Bing from the Institute of Physics.
The lineup is quite powerful.
Seeing that the time was up, Xu Qingzhou slowly exhaled and brought up the homepage of the PPT.
Now, I can almost put an end to my undergraduate career.
