Math professor returns to routine

Chapter 509: Formula Change

Friday night.

Tang Wan copied the compressed package of the plan document, pasted it into the vx chat box, and clicked send.

As the notification of successful sending appeared, Tang Wan leaned back and collapsed on the chair like a deflated ball.

"Finally finished!"

This week was the most tiring week for Tang Wan since she entered college.

The new semester has just started, and the daytime classes are almost full. At night, I either work in the student union or take elective courses, and then I go running after that.

At the same time, the lecture publicity plan was always following closely behind. Since it was the first time I was involved in it, I was unfamiliar with many things and even had no idea what to do. I could only look up information everywhere and cross the river by feeling the stones.

Fortunately, the difficult days are finally over.

After submitting the plan, I can take a break for a while.

As for whether the subsequent plan would be rejected, Tang Wan didn't bother to care. She would deal with it later and just lie down and let it rot for now.

If you don't rest, you will be ruined.

Tang Wan closed her computer, picked up the phone next to her, and sent a message to Lu You.

……

the other side.

Lu You stood at the podium at the front of the classroom, long sleeves lifted up, writing on the blackboard with chalk in hand, and giving a lecture in an orderly manner.

offstage.

Gong Qing, Zhang Zhichuang and Bi Yangde sat upright with serious expressions, and from time to time the sound of pens scratching across paper could be heard.

There were four other people in addition, Xiao Liang and his three graduate students.

"You three should read more and learn more, especially his teaching ideas. Mathematics is a field that is too broad and too deep to be explored far by the power of a few people. As researchers in this field, we cannot just learn knowledge by ourselves, but also consider how to pass it on so that more people can learn and lead them to join our ranks..."

The three of them turned into a timer, and Xiao Liang read along as they nodded.

To graduate students, a supervisor is their immediate superior and the one who provides them with food and clothing. His words may be useless, but their subordinates must listen to him, or at least pretend to listen on the surface.

Lu You spoke for more than ten minutes before stopping. The entire blackboard was filled with densely packed characters.

"You three should add him on WeChat later. You will be responsible for the group discussion afterwards."

Regardless of whether the three agreed or were willing, Xiao Liang stood up and walked to the podium.

"You spoke very well. Thank you for your hard work." Xiao Liang said with a smile.

"Thank you for the compliment, Professor." Lu You responded modestly, his heart remaining calm.

As a professor in my previous life, I have done a lot of teaching, imparting knowledge and answering questions. Although I am not very good at it now, I am certainly very proficient at it through practice.

Lu You stepped down from the podium and sat back in his seat.

Xiao Liang continued with what Lu You said, gave a deeper explanation, and raised new questions to guide the extension of thinking.

Xiao Liang only touched upon most of the questions briefly, allowing everyone to take notes on the ones they were interested in and go back to explore and study on their own, without elaborating too much.

Twenty minutes passed.

Xiao Liang felt that he had almost finished speaking, so he put the chalk back into the chalk box and brushed the dust off his hands.

Teaching requires a moderate degree of relaxation and gradual progress. If too much knowledge is thrown out at once, students will not be able to remember it at all and the teaching will be in vain.

"That's enough for today. get out of class dismissed."

Everyone packed up their belongings.

Lu You took out his cell phone and turned on the screen.

Two messages popped up one after another, one from twenty minutes ago and the other from fifteen minutes ago.

[Ai Fei: Have you finished your group discussion? ]

【My beloved concubine: I will go find you now. 】

Lu You edited the message and replied immediately.

【Husband: It just ended. 】

【Husband: Where are you? I will go find you. 】

【My beloved: Don’t be in a hurry.】

[My beloved: I am waiting for milk tea. ]

[My beloved: Take your time~(∠ω<)]

Tang Wan said there was no rush, so Lu You naturally didn't rush either, and he slowly and methodically put away the draft papers and stationery on the table.

After putting everything away properly, Lu You touched the table to make sure nothing was left out. He fastened the magnetic buckle of his backpack and was about to stand up when a faint light fell from above his head.

Looking up, I saw that the person coming was one of the three graduate students under Xiao Liang.

He is very tall and thin, with a crew cut, wearing glasses, delicate features, a smile on his lips, and a cheerful and sunny temperament.

"Hello, junior, can I spare you a few minutes?"

Zhang Zhichuang and the other two all looked at him curiously.

"Senior, if you have something to say, just tell me." Lu You said politely.

The boy was obviously a straightforward person. He took out his cell phone and showed the QR code to Lu You.

"Add me as a friend on WeChat. The professor said that we will be in charge of the group discussions together with you in the future."

"Ok."

Lu You took out his mobile phone again, opened vx, scanned the QR code, and the corresponding personal business card popped up on the main interface.

The avatar is the official logo of CSGO, and the name is Superman.

This guy might be a scoundrel!

Click to send a friend request. The next second, the request is approved and the friend relationship is successfully established.

"Junior, let's communicate and study together when we have time!" The boy waved his hand and left happily.

Lu You also put away his cell phone, put on his schoolbag, and left with Zhang Zhichuang and others.

Passing by the podium, Lu You deliberately stopped and said goodbye to Xiao Liang.

"Professor, let's go."

"Okay, pay attention to safety on the road."

Walk out of the classroom, around the corner and into the stairwell.

Zhang Zhichuang seemed to have broken free from a layer of restraint and sighed to the sky.

"Professor Xiao is really good at torturing people! He throws a bunch of questions that are beyond the scope of the syllabus, not only does he not give any hints, but he also requires us to give presentations on stage during the group discussion next week. Does he think that all of us are as good as Brother Lu?"

His words were full of resentment towards Xiao Liang.

"Be content! At least Professor Xiao only asked us to pick one problem to study instead of all of them." Bi Yangde put his hands in his pockets, teasing with self-mockery.

"Professor Xiao hasn't even asked us to truly solve the problem yet." Gong Qing added.

Zhang Zhichuang took two steps and squeezed next to Lu You, winking at him.

"Brother Lu, you must have decided which problem you want to study, can you guide me?"

"Do you know why the school holds a school discussion group every week and has professors to guide us?" Lu You asked back.

"please say."

Zhang Zhichuang acted as if he was listening attentively, and Gong Qing and Bi Yangde also pricked up their ears to listen attentively.

"Because the high school learning model is not applicable to college. The purpose of high school learning is very simple, there is only one, under the unified standard, to stand out from the crowd. How to do it? Two words, practice questions.

There is a circle drawn on the top. Students will continuously fill themselves up through learning, making their own area bigger and trying to cover the circle as much as possible. The larger the area covered, the higher the score they will get. This process is called practicing questions.

The four of us were recommended to Capital University through math competitions. It may seem that the method is different from the college entrance examination, but in essence, the two are still part of the same framework. Limited knowledge scope, repeated practice questions, direct and crude score competition, the higher the score, the lower the score, the lower the score.

In college, exams still exist, but they are no longer the only purpose of learning, but one of the criteria for measuring personal ability. If you still only know how to solve problems, you can only get a good GPA on paper, but it will not help you in other aspects, such as management, handling affairs, and interpersonal relationships.

The essence of doing practice questions is just to walk back and forth on the road that predecessors have walked, but what schools want is talents who can stand on the shoulders of predecessors, look far into the distance, and have the ability to explore independently, think independently, discover, analyze and deconstruct problems. "

Lu You's lengthy speech successfully touched Bi Yangde and Gong Qing, and they both looked thoughtful.

Zhang Zhichuang is like a piece of wood, and he won't listen to anything.

"Brother Lu, after all this talk, are you going to take me with you or not?"

"You really don't understand what people are saying!" Lu You sighed, feeling helpless and too lazy to say more. "When you learn to think about how to solve a problem the first thing you do, I will take you with me."

As the words fell, the group walked out of the gate of the teaching building.

Under a street lamp not far away, a figure stood alone, looking at them quietly.

"Someone is looking for me. I'll leave first. See you on Sunday."

After watching Lu You walk away for a distance, Zhang Zhichuang nudged Gong Qing with his elbow and asked, "Old Gong, what do you think Brother Lu meant?"

The scene where Lu You and Tang Wan meet under the street light touched the soft spot in Gong Qing's heart, and he couldn't help but think of his girlfriend who was thousands of miles away.

Just as he was thinking about it secretly, he was interrupted by Zhang Zhichuang's voice, and Gong Qing's face immediately turned bad.

"Ask, ask, ask, ask everything. Are you a kindergarten kid? Can't you figure it out on your own?"

"Tsk, you have relatives here, and you are so angry?" Zhang Zhichuang turned his gaze to Gong Qing again, "Xiao Bi, come and talk to your uncle."

Bi Yangde didn't let his imagination run wild and replied, "The master's meaning is actually very straightforward. He hopes that you will seek his help in the process of solving the problem, rather than asking him for help as soon as you encounter difficulties without thinking about it."

"That's it? He could have just said it directly, why is he hinting at it?"

"I guess the great god never thought that you couldn't understand Chinese."

……

Under the streetlight.

Lu You stopped in front of Tang Wan and wanted to pinch her face, but then he saw her holding a milk tea in her hand, a straw in her mouth, and her cheeks were puffy, so he gave up the idea.

If it sprays out and stains your clothes, it will not be a good thing.

"How long have you been waiting?"

Tang Wan's cheeks shrank and there was an obvious swallowing movement in her throat.

"Just arrived."

"What did you drink?"

Tang Wan shook the cup, making a gurgling sound. "Blueberry yogurt shake, with milk jelly, green rice balls, and popping pearls."

"Have you prepared my share?"

"Of course." Tang Wan raised her hand. There was a green thermal bag hanging below her. The surface of the bag had a celebrity endorsement printed on it. "It's the same as mine, but it's less sweet."

"I knew that my baby has me in his heart!" Lu You took the bag with a smile.

"You're welcome!" Tang Wan raised the corners of her mouth, revealing an innocent smile, "Just use more strength when you chisel me tonight."

Lu You pasted the seal of the bag, which had just been torn half open, back on and returned it to Tang Wan in its original state.

"I have always been upright. I would not bother to sell myself in such a lowly business!"

Tang Wan's smile deepened, her index finger touched Lu You's chest, her eyes half-closed, "Little man, do you think that if you don't accept my kindness, you won't have to eat tonight? I tell you, no way! You must feed me tonight."

Since struggling is futile, just face it calmly.

Lu You opened the package, took out the milk tea, inserted the straw, and took a big sip.

The sweetness of blueberries, the sourness of yogurt, the soft and fragrant green rice dumplings, the bursting texture of popping balls, and the cool and stimulating smoothie are all intertwined and blended together, creating a full sense of layering.

The only drawback is that mixing the milk jelly and the popping beads together can easily clog the straw.

"Then let's go! Go for a run first, then go home and work after you're done."

"Ah~ Do you want to run on the weekend too?" Tang Wan pouted, looking reluctant.

“Is Friday red on your calendar?”

"Oh, can't you take a day off?" Tang Wan leaned close to Lu You, raised her index finger, and looked at him from bottom to top, "One day, just one day!"

Lu You's heart was shocked, but his face remained unmoved. He said in the tone of a teacher teaching a student: "If you run one more day now, you will run one less day in the future. If you work harder now, the physical test next month will be easier. Don't you understand such a simple truth?"

Tang Wan's smile gradually disappeared and her tone became colder.

"Lu You, do you know that sometimes you really..."

"I found a music restaurant and bar. I'll treat you after your run."

"It's so adorable!"

Tang Wan stood on tiptoe and kissed Lu You on the lips, but they separated in an instant.

"What are you waiting for? Let's go to the playground! I can't wait to run!" Tang Wan put her arm around Lu You and hurriedly pulled him forward.

"Why are you in such a hurry? The playground is always there, and it won't grow legs and run away."

"My stomach is rumbling and I need a midnight snack!"
