Volume 1: Student Life Chapter 95: The stretching posture is so beautiful
Chen Zhou returned to his seat and found that Yang Yiyi was concentrating on reading the textbook and had not noticed that he had returned.
Chen Zhou looked at the time. It was already 3:28 in the afternoon.
They stayed in the library for nearly two and a half hours.
Chen Zhou looked at Yang Yiyi again, then raised his head, took a sip of the spiritual potion, and devoted himself to studying complex functions again.
This time no one disturbed him, and Chen Zhou studied the contents of the textbook eagerly.
Chen Zhou closed the textbook only after finishing all the questions in Exercise 2 of Chapter 2.
Through the use of psychotropic potions during this period , he found himself spending more and more time studying in immersive mode.
Even after the effects of the psychiatric potion wore off, he was still immersed in the book.
Chen Zhou guessed that it was the mental potion that enhanced the active learning habits. Maybe one day he would be able to get rid of the mental potion and achieve that immersion mode relying solely on his own learning habits.
Chen Zhou turned his head to look at Yang Yiyi beside him. The girl was still concentrating on the math textbook.
He poked Yang Yiyi with his hand, and Yang Yiyi turned her head away with a confused look on her face.
"Are you hungry?" Chen Zhou asked softly.
"Ah?" Yang Yiyi didn't react for a moment.
Chen Zhou pointed to his watch, and Yang Yiyi noticed that it was almost 6 o'clock.
"Hmm~" Yang Yiyi stretched, then stood up and said, "Let's go."
She found that Chen Zhou did not move. She looked at Chen Zhou strangely and found that Chen Zhou was blushing.
Yang Yiyi just remembered that when she stretched just now, her clothes were stretched tight on her body. What on earth did this guy see? !
A blush instantly appeared on her face, and she slapped Chen Zhou hard: "What... are you thinking about?!"
Chen Zhou touched his nose awkwardly, stood up, took Yang Yiyi's hand, and left the library.
On the way to the cafeteria, Yang Yiyi thought of what happened in the afternoon and asked, "Chen Zhou, do Professor Wu and Professor Zhang want to talk to you about something?"
Chen Zhou replied: "Professor Wu asked me why I was studying complex functions and whether I had finished learning calculus. I told him the truth. Then, Professor Wu enthusiastically invited me to join their research group. Professor Wu praised my strong learning ability, so I couldn't refuse and had to join them."
"Just brag, I don't believe it." Yang Yiyi said with a smile.
"Hehe. Well, actually..." Chen Zhou told Yang Yiyi the actual situation.
After hearing what Chen Zhou said, Yang Yiyi was happy for Chen Zhou, but she still said, "It's a good thing to be able to join the research project in your freshman year. You should help the two professors."
"Yeah, I think so too." Chen Zhou nodded and said, "It should be a very simple topic, so they let me join. But it's a good thing that I can get some training."
"Yeah." Yang Yiyi agreed with Chen Zhou's idea and approved of Chen Zhou's current mentality.
After Chen Zhou experienced the psychological distress caused by the chemical biology experiment, his mentality became more stable.
After finishing their meal, they walked hand in hand to the lakeside of Yanda University, feeling the breeze blowing on their faces, bringing a cool feeling of early summer.
The lake of Yanda is the most famous scenic spot of Yanda.
Chen Zhou looked at Yang Yiyi, and thought of the girl stretching, and said softly: "Yiyi, you are so beautiful..."
But Yang Yiyi didn't hear it. She was staring at the ripples on the lake reflected by the lights.
Chen Zhou and Yang Yiyi admired the lake view for a while, then walked towards the library to continue reading.
Chen Zhou and Yang Yiyi didn't come out of the library until closing time.
"Yiyi, tomorrow is the 65th National Day, shall we go watch the military parade?" Chen Zhou suggested on the way back to the dormitory.
"Okay." Yang Yiyi agreed happily. After thinking for a while, she asked, "Why didn't uncle and aunt come over to play during the National Day?"
Chen Zhou said, "Originally, there was a military parade on National Day this year, and I wanted them to come and have some fun and watch the parade. But I asked them several times, and they both said they were busy at home and didn't want to come. Well, let's wait for the next opportunity."
"That's such a pity. A military parade only happens once every five years." Yang Yiyi said regretfully.
"Then, will your mother come?" Chen Zhou thought of the woman who smiled at him at Wanxi Station.
Yang Yiyi: "She doesn't have time either."
Chen Zhou: "Then let's just do it the two of us and shoot more videos."
Yang Yiyi said disdainfully: "Hey, your photography skills are so bad that the fireworks are blurry."
Chen Zhou: "You're talking nonsense, that's clearly a blur effect..."
Yang Yiyi: “…”
Chen Zhou sent Yang Yiyi downstairs to the dormitory: "Go to bed early tonight, see you tomorrow morning."
"Yeah, you too." Yang Yiyi thought of something else and added, "Don't stay up late reading."
"Okay, got it." Chen Zhou waved his hand and turned to walk towards his dormitory.
It's impossible not to stay up late. Don't you see Li Li is still writing furiously?
How can you make up for the time lost in playing without staying up late?
Chen Zhou returned to the dormitory, took out the complex function textbook from his backpack, and prepared to continue studying.
He has already read the middle of the third chapter. If he works harder, it won't be a problem to finish all of it within three days.
He raised his head and took a sip of the mental potion.
Chen Zhou opened the yellow textbook and was quickly immersed in it.
Although the content of the complex function textbook is not much, it is relatively difficult.
Through this period of self-study, Chen Zhou felt fortunate that he chose to study advanced mathematics as the first task after the system was activated.
Although Advanced Mathematics is not a textbook for mathematics majors, it is a very comprehensive basic textbook that can lay the foundation for the study of many mathematics professional textbooks.
This is also one of the reasons why Chen Zhou’s self-study results are very good.
"...Cauchy inequality, suppose f(x) is analytic in the area Ω, and in Ω |f(x)|≤M, then AZo∈Ω, 0＜r≤dist(Zo,aΩ), always |f(n)(Zo)|≤n!M/r^n..."
While looking at the Cauchy inequality in the textbook, Chen Zhou wrote down the content and its proof on a piece of draft paper.
This has always been Chen Zhou's habit. When reading, he takes notes with a pen to deepen his understanding of the knowledge content.
The contents of Chapter 3, Cauchy's theorem and Cauchy's inequality, are basically all new knowledge, and Chen Zhou soon filled up his draft paper.
By the time he finished reading the third chapter, he had already filled three pages of draft paper.
These draft papers are all A4 paper.
Next is Exercise 3, which has a total of 35 questions, and the last two questions are marked with *.
Chen Zhou used the knowledge he had just acquired today to solve these exercises, while also improving his proficiency in the knowledge.
Chen Zhou finished the previous questions smoothly, except for the last one which was a little troublesome.
"Let f:D(0,1)→D(0,1) be an analytic mapping. Prove that for any smooth curve γ in D(0,1), s(f(γ))≤s(γ), where s(γ) denotes the non-Euclidean length of the curve γ."
Chen Zhou thought for a moment and began to write the proof on a piece of scratch paper: "Proof: Analytical mapping f..."
By the time Chen Zhou finished writing, it was exactly 12 o'clock in the evening.
Chen Zhou stretched his body and thought that Professor Wu would send some information to him, so he said to Li Li who was still reading, "LiLi, can you lend me your computer?"
"Oh, open it yourself, the password is 123456." Li Li pushed the computer to Chen Zhou.
He watched Chen Zhou turn on the computer, log into his email, and then download a compressed package.
Li Li asked curiously, "What did you just order?"
Chen Zhou replied: "Information sent by Professor Wu."
Li Li: "Professor Wu? Why did he send you the information?"
"It's the research material for the topic." Chen Zhou unzipped the compressed file downloaded from the email, opened the folder, and pointed at the material on it. "It's an applied research on the mutual penetration and integration of advanced algebra and mathematical analysis."
Li Liwei frowned, with a big question mark on his face, and leaned his head forward.
