During this time, Shen Qi was no different from ordinary single dogs in terms of life and study, attending classes, studying on his own, writing papers, and preparing materials for studying abroad.

The class is a physics class, and Shen Qi plans to continue to complete several physics major courses in this semester and get credits.

The SOS project office has become Shen Qi's one-man study room, and the project is nearing completion but has not yet been finalized, and the office can still be used.

Another S in SOS, Sun Erxiong occasionally came to the project office to communicate with Shen Qi for a while.

O went home to recuperate for more than a month, the office was empty, Shen Qi, who stayed behind, occasionally stared at the wall in a daze, Euler, Gauss, they didn't speak, just laughed.

"How's the recovery?" Shen Qi and Ou Ye sent a message, and the two of them chatted through their mobile phones for half an hour.

Ouye: "It's good. ”

Shen Qi: "Really?"

Oye: "It's okay. ”

Shen Qi: "Ouye, you have changed, you have learned to lie." ”

Oye: "Actually...... The recovery is so-so. ”

Shen Qi: "It seems that I can't treat you to Christmas dinner." ”

"It's a pity that I may not be able to go to Switzerland this winter vacation. Ou Ye sent this text message, with a string of tearful expressions, and the yellow emoji patterns were densely coded with dozens of them.

"Get your body good first, we can go to Switzerland at any time. Shen Qi comforted.

Ouye: "Well, what about you, how are you doing?"

Shen Qi: "The old three, class, running, writing papers. By the way, our SOS project is about to produce results, and the project paper will be published before the Spring Festival. ”

Ouye: "Great! Wait a minute, my mom told me to take my medicine, wait for me for a minute." ”

It was punctual, and a minute later, Ou Ye sent a message: "I'm back." ”

Shen Qi: "You don't seem to mention your mother very much, what kind of profession is she engaged in?"

Ouye: "Take care of the housework at home, take care of me, and occasionally go shopping. ”

Oh, full-time wife, Shen Qi returned: "Your family is very happy. ”

Oye: "My dad is prying the door, Mingchat, 88." ”

Old Ou pried the door of your boudoir? Typo right? It should be a knock?

Shen Qi put away her mobile phone and analyzed it from Ou Ye's text message, her mother told her to take medicine, and she said wait for me for a minute. Her dad knocked on the door, and she said we'll talk tomorrow, 88.

According to the preliminary judgment, Ou Ye's mother is responsible for boiling medicine, and his father is responsible for checking the post, and the family division of labor is clear.

This should be a harmonious and happy family of three, with a father earning money to support the family, a mother presiding over the housework, and a daughter studying in a prestigious school.

The fly in the ointment is Ouye's physical health.

On the days when Ou Ye went home to recuperate, Shen Qi had a dull life, and he always felt that something was missing.

This directly or indirectly affected Shen Qi's performance in the physics major exam, with only 98 points in electrodynamics and 95 points in quantum mechanics.

Last semester, Shen Qi took the exams of 7 required courses for physics majors, with an average score of 99.3 points, and six of them received perfect marks.

This semester, the final exams of electrodynamics and quantum mechanics that ended first, one scored 98 points and the other scored 95 points, but neither of them reached the average line.

Shen Qixin calculated the average score of the latest edition, 98.7.

This is his second degree in physics, and his current grades.

"It's falling, it's falling. ”

Looking at the report card, Shen Qi felt lost.

If it continues like this, the day you get your second degree in physics, you may not even be able to keep the psychological bottom line of an average score of 95 points.

"I've been in a bad state lately, I haven't scored a perfect score this semester, and my solid state physics score has just come out, 94 points, which is heartbreaking. In any course, I have never scored below 95, this is the first time. ”

Shen Qi complained to Ou Ye on WeChat: "Compared with mathematics, my physics is very bad, maybe I chose the wrong direction, mathematical physics is not suitable for me." ”

Ou Ye: "Isn't it, confused? This is not like the style of Big Brother Shen!"

Shen Qi: "Maybe, I'm lost again when I'm not in good shape." ”

Ou Ye: "Then with your average score of 98.2 in physics, how can you rank in the School of Physics?"

Shen Qi: "Temporarily ranked first, tied for first. ”

Oye: "!!"

Shen Qi: "???"

Ouye: "Wait a minute, it's time for me to take my medicine, a few minutes." ”

After the daily chat between the two was interrupted for a few minutes, Ou Ye resumed speaking: "I really want to go back to school." ”

Shen Qi: "Then you come back quickly, if you don't come back, Zhou Yu'an should surpass you, he has been fierce recently, and he has scored three perfect scores in the real function, differential geometry, and partial differential equations." ”

Oye: "!!"

Ouye: "Wait a minute, there's still a medicine I haven't taken, a few minutes." ”

After nearly two months of recuperation at home, Ou Ye missed a lot of math courses.

Although Ou Ye has a strong self-learning ability, Shen Qi thinks that he should help her.

Based on his own self-study experience and the teaching characteristics of the Department of Mathematics of Yan University, Shen Qi compiled a version of his learning experience and sent it to Ou Ye.

"In terms of real functions, in terms of practicality, Riemann integrals are sufficient. However, for the basic theory, the new theorem based on the countable additivity of the Lebeberg measure is in stark contrast to the conclusion based on the limited additivity of the Jordang capacity...... Ou Ye, think about the Fourier coefficient carefully, don't you have a leaf in your name, the leaf of Fourier. ”

"After Fourier, we have to talk about Euler. The four kings of differential geometry are Euler, Monge, Gauss, and Riemann, and this branch was laid by Euler, and Gauss and Riemann carried forward......"

"We have to look farther and deeper than the average student, and after introducing curvature into n-dimensional geometry, we can then consider specific manifolds on which finite spatial forms can be moved. ”

"Physical space is a special kind of manifold...... Do you still remember the closed Riemann surface I mentioned to you when we first met in the Golden Autumn Camp, and Klein tinkered with the Klein bottle on the basis of Riemann...... I'm sorry to go far, back to differential geometry......"

Shen Qi devoted his life's learning to the completion of this edition of "Learning Experience for Special Students of the Department of Mathematics of Yan University" very devotedly.

The length is not long, it is a condensation of the essence, and there is only one reader, only for Ou Ye's reference and learning.

Shen Qi is tailor-made for Ouye, which belongs to the private customized version.

Ou Ye was particularly moved, she repeatedly studied the benefits sent by Shen Qi as far as her body allowed, and stared at the documents in the computer for a whole day.

On Christmas Eve, Ou Ye still couldn't return to Yanda to have a Christmas dinner with Shen Qi after all.

At the Christmas Eve party, Shen Qi spent it with three roommates in the dormitory.

The four boys said okay, no one would bring their families, and it was a men's party.

After eating, he sang K, Zhou Yu'an, who has always been slamming the door, was abnormal, he was in a happy mood tonight, he was generous, and he spent hundreds of dollars to bear half of the cost of the dormitory activities.

"Friday hundred, women's clothing!"

"Friday hundred, women's clothing!"

"Friday hundred, women's clothing!"

Shen Qi, Cai Qing, and Luo Ji strongly asked Zhou Yu'an to wear women's clothes and sing.

In the five exams that have ended in the first semester of the sophomore year of the Department of Mathematics, Zhou Yu'an scored five 100 points in a row, and five hundred.

In addition to the three mathematics courses of real variable functions, differential geometry, and partial differential equations, Zhou Yu'an also scored full marks in his other two public courses.

Zhou Yu'an has become the new leader of the mathematics department, ranking first among regular students.

"Don't!

"Damn! Are you psychopathic! Why do I wear women's clothes?" Zhou Yu'an clasped his arms and curled up in the corner of the KTV box shivering, his coat had been stripped by three roommates, and only a close-fitting vest remained.

"Five big guys with 100 points in the exam in a row, you must wear women's clothes! Big guy women's clothes, big guy drink!" Shen Qi, who has never scored 100 points this semester, borrowed a set of princess clothes from the KTV manager.

Shen Qihu's body was shocked, with wine in his left hand and women's clothes in his right hand, he slowly walked in front of Zhou Yu'an......
