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, uttering vague murmurs and arching against him again.
He must be really tired this time, after all, the school beauty Song used a fatal scissor kick on him last night.
The eldest brother locked up He Jinyin, and He Jinyin locked up the eldest brother.
Xu Qingzhou put one hand behind his head, enjoying the quiet morning.
Half an hour passed.
The girl in Xu Qingzhou's arms stirred and woke up. He slowly closed his eyes and pretended to sleep, a little curious about this girl's first reaction after getting up.
Song Yao opened her eyes and looked at Xu Qingzhou carefully, and found that he was still sleeping. She couldn't help but breathed a sigh of relief. Thinking of the madness last night, her face was burning.
A serious person like her has been led astray by this bad guy.
Song Yao cursed secretly in her mind and got up slowly. She didn't know where her clothes and pants were missing. After searching for a long time, she finally saw her clothes on the ground at the end of the bed.
All dirty.
She could only get out of bed and go to the closet to find clean clothes.
After everything was put on and she turned around, Song Yao froze. It turned out that the person who had been sleeping soundly just now was looking at him with wide eyes, a naked smile in his eyes.
In broad daylight, naked.
Haha, pretending to be cold again.
Xu Qingzhou asked with a smile: "Won't you 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.
"Are you tired?" Song Yao still asked 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."
The arrogant person has been pinned down on the bed by Song Yao and beaten wildly.
After finishing the content of the Polignac conjecture index sum, Xu Qingzhou put it aside and concentrated on his thesis. In mid-October, Professor Gu called and agreed with Xu Qingzhou to defend on November 2.
So in the following time, Xu Qingzhou was working on his thesis, mainly focusing on the theory of renormalization groups.
Some people have commented that in terms of function, the renormalization group is like sweeping a house of garbage under the carpet without completely removing it.
There is some truth to this. The starting point of renormalization is the renormalization of the wave function. This seems legal, but when we study the renormalization carefully, we will find that the renormalization actually redefines the entire field. .
It is not studying the original field "discussing the matter", but quietly changing the field to study.
Of course, just as Professor Gu told him last time, absolute perfection cannot be pursued in many things, and the actual value of a research tool cannot be evaluated arbitrarily.
At the very least, renormalization groups are widely used, whether in the calculation of quantum field theory or in the currently popular condensed matter physics, which shows that they are quite valuable.
Xu Qingzhou first used path integral to calculate the amplitude, and then calculated 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 renormalized group flow.
October has passed, and the day for the defense has quickly arrived.
8am.
"Thesis, Water Glass"
Song Yao was muttering to herself as she was helping Xu Qingzhou check the contents of her bag. She asked for leave from Professor Li Daiyue and wanted to accompany Xu Qingzhou for his defense.
Xu Qingzhou was sitting on the sofa peeling oranges, and found that the school beauty Song was more nervous than the respondent himself. He smiled and comforted: "Don't worry, I have brought everything."
Regarding the undergraduate defense, I can talk about it with my eyes closed.
Song Yao checked the things, then walked over and snatched half of the oranges that Xu Qingzhou had peeled.
"After you finish your defense today, you will have graduated with a bachelor's degree. When you graduate with a master's degree next year, you will go to study abroad."
"I can wait." Xu Qingzhou said that if he goes out, he is confident that he can get his diploma in one year. Of course, getting the certificate is relatively simple, but the most important thing is to get more exposure to cutting-edge mathematics knowledge.
"How can we wait?" Song Yao curled her lips, 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 is willing to let you go directly?" Song Yao is Professor Li's treasure now. He teaches everything he has and takes it with him at all times. He can't wait to pour all his knowledge into Song Yao's head.
"I am an exchange student, it's not like I won't come back."
Seeing Song Yao finish eating the oranges, Xu Qingzhou picked up a freshly washed grape and handed it to her mouth.
Song Yao held the grape in her mouth, bit it into pieces, and winked at the sourness, "Hiss~ It's so sour~"
"I was deceived by that eldest sister. This catty of grapes is all sour." Xu Qingzhou was indignant.
"You know sour ones?"
Xu Qingzhou nodded: "I just tasted two."
"Then give it to me?"
I really want to give this guy two lumps.
But Song Yao still held back. She already doubted whether this guy had a physique that would make him happy when he was beaten. He knew that he would be beaten by her, but he still enjoyed it and she couldn't let him succeed.
Xu Qingzhou said with a smile: "You can't just blame me."
pia~
So, Xu Qingzhou ate a set of Tathagata Palms from Song Yao.
After packing up at home, seeing that it was almost time, the two of them changed their clothes and got ready to go.
In November, it was the day when the first snow fell in Kyoto. The temperature was low, so both of them put on thick clothes.
Song Yao was wearing a white sweater, and her slim body was immediately revealed.
Xu Qingzhou leaned against the shoe cabinet, admiring the beautiful figure of Song school beauty.
Seeing that Xu Qingzhou was looking at her again, Song Yao zipped up her coat to cover her beautiful body, and clenched her fists. This guy was about to answer, and he was still acting so carelessly.
Xu Qingzhou shrugged innocently. I never get tired of the school beauty Song.
At the beginning of November, there was still some time before heating, but after all, it was much hotter inside the house 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's still a little cold, and there are puffs of hot air exhaling.
Xu Qingzhou took one of Song Yao's hands and put it in his pocket. The two of them went straight to the defense classroom without stopping.
At 9:40 in the morning, Xu Qingzhou and Song Yao arrived at the 2021 classroom of the Mathematical College on time.
"Brother Tong."
Xu Qingzhou and instructor Zhu Sitong greeted each other.
"Are you ready?" Looking at the boy who walked in, Zhu Sitong sighed in his heart. He only entered the school in September last year and graduated in November this year. No one can compare with this speed.
Based on this kid's achievements, it would not be too much to directly award him a doctorate.
However, there is no precedent for this.
"Well, that's it."
Xu Qingzhou nodded slightly.
After greeting Zhu Sitong, he went to the stage to prepare for his defense, while Song Yao went to sit in the corner of the lecture theater first.
November 2, 10 am.
The defense teacher is already in place.
Professor Gu Zhizhong, Academician Wang Lin, and Academician Chu Jiangfeng from the Institute of Mathematics.
Academician Ma Liangzai, Professor Zhao Shengwen and Academician Yang Bing of the Academy of Physics.
The lineup is quite strong.
Seeing that the time had come, Xu Qingzhou slowly exhaled and called up the homepage of the PPT.
Now, I can almost bring my undergraduate career to an end.
