"There is something special about this year's college mathematics competition... Who came up with this question?"
Office of the Dean of the School of Mathematics.
Looking at the line of calculations written on the blackboard, Wang Shuangquan touched the stubble on his chin with his right hand, and a solemn look appeared in his eyes.
Standing next to him is Professor Li Xuesong from the Department of Mathematics, a leading figure in pure mathematics in China, and one of the examiners of the National College Student Mathematics Competition in early September.
"It seems to be Professor Liu Shoufeng from the Xia Guo Institute of Mathematics."
"It was actually this old guy who asked the question..." A look of surprise appeared on Wang Shuangquan's face, and he nodded and said, "No wonder..."
Mathematics is the foundation of science, and Xia State, founded on science and technology, attaches great importance to mathematics. Every year, it holds national events such as the National College Student Mathematics Competition, which is mainly for college students majoring in mathematics. The winners are expected to be directly admitted to the national key universities. research unit.
Usually, in order to increase the score, the last big question is often asked by professors from the Xia Guo Institute of Mathematics.
But no one expected that no one from the entire examination committee could solve the last big question of the year.
Even among these people, Professor Liu Shoufeng himself is included.
As a member of the main examination committee, Professor Li Xuesong still remembers how the old man played tricks on him with an innocent face when he found him -
"I never thought this question would be so difficult. It suddenly occurred to me that it seemed interesting, so I wrote the test paper."
Now it seems that this question is quite beautiful.
Maybe it will become a mathematical conjecture by then.
Mr. Liu Shoufeng himself was happy and gave up, but he suffered a lot from the examination committee of their competition.
Just like that, half a week has passed since the end of the exam, and the answer to this question is still a mystery...
Seeing that Dean Wang Shuangquan did not respond for a long time, Professor Li Xuesong asked tentatively.
"What do you think of this question?"
"I don't have a good idea yet, but my intuition tells me that the answer shouldn't be difficult?" Wang Shuangquan thought for a moment and shook his head, "Let me think about it for two more days... Speaking of which, where is the Yanjing Institute of Mathematics? ?”
The Yanjing Institute of Mathematics can be regarded as another major mathematics research institution in Xia State. Unlike the Xia State Institute of Mathematics, which focuses on applied mathematics research, the Yanjing Institute of Mathematics mainly studies pure mathematics.
It is obviously better to leave this kind of number theory problem to experts.
"The questions have just been sent to them. They are probably holding a seminar at the moment."
Dean Wang nodded and touched the stubble on his chin.
"That should be stable."
"Hey, I thought it was my ability that had declined before, but I didn't expect that even you, old man, couldn't figure it out. It seems that the problem still lies in the question itself."
Looking at Professor Li Xuesong smiling there, Dean Wang felt a little embarrassed and coughed.
"What do you mean I can't figure it out... Didn't you just get it from me?"
"Haha, I don't care, anyway, I feel balanced in my heart!" Li Xuesong laughed and waved his hand, "No more nonsense, I'm going to class, there will be a high math section in a while, and there are two classes of homework waiting for me. ."
"Homework? You shouldn't be assigning this question as homework, right?"
"It's just a question for thinking. I don't ask them to do it. They can only do as much as they can."
Looking at this unreasonable old thing, Wang Shuangquan laughed and said, "Aren't you bullying others?"
If he had this ability, he would have already been sent to Yanda University with his first grade score in the National Mathematics Competition. Although Jiangcheng University is also among the top 10 universities in Xia State and even the world, its resources are still a little inferior to those in Yanjing.
"Bullying people? Haha, I think the pressure is not tight enough! These freshmen who have just come to the university are like ducks in the mountains. They have no discipline at all! The mental outlook of today's students is far worse than what we did back then. , It’s true that one generation is inferior to the other!”
As he spoke, Li Xuesong shook his head.
Looking at his old friend, Dean Wang coughed dryly and said.
"Each generation has its own way of living, so don't always rely on the old calendar to ask today's students. Ask yourself, would you rather your grandson live in the old calendar, or in the new era?"
"Can it be the same? How old is my grandson?" After all, he couldn't tell the leader. Li Xuesong muttered and changed the topic, "It's almost time, I'll go back first."
Dean Wang smiled and nodded.
"go Go."
It happened that this question was quite interesting, and he wanted to think about it quietly for a while.
Maybe it can be solved soon
Although it seems quite challenging...
…
Ding ding ding—
"Hiss... Why hasn't Hao Yun come yet?"
Seeing Lao Li who had already walked into the classroom with the bell ringing, Zheng Xueqian looked around anxiously and whispered to Liang Ziyuan who was sitting next to him, "Isn't this guy overslept?"
He wasn't worried about Hao Yunque's absence from class. The main reason was that he helped occupy the seat too far forward, leaving the book alone and awkward. Especially this kind of small class with only two classes is even more annoying.
Liang Ziyuan: "... maybe."
"Damn it, please tell me if you don't come."
Zheng Xueqian complained in a low voice and took away the book on the table before receiving a blank look.
"Please be quiet during class."
Li Xuesong, who knocked on the blackboard and walked up to the podium, dropped the advanced mathematics textbook in his hand on the podium, put his hands behind his back and looked like a worldly expert.
"The academic committee of Class 1801 accepted the homework."
As soon as I heard that homework was being collected, the classroom suddenly became filled with sighs and sighs. The top students sitting in the front row looked at each other, but they only saw helpless expressions in each other's eyes.
"Did you write it?"
"I didn't write it."
"This question is too difficult..."
"Yes, yes, I can't write it at all!"
"I still have to hand in my homework. Isn't that question a reflection question..."
"It's over, it's over."
Seeing the reaction of the students in the audience, Li Xuesong didn't make any expression on his face, but he laughed twice in his heart.
Can't do it
What a coincidence!
He Ping, who was sitting in the first row, bit his thumb and looked at the three to five pages of draft paper on the table, frowning and not saying a word.
Zhou Xuan, the little fat man sitting next to him, poked his arm nervously with a pen and asked in a low voice.
"He Shen, have you written it out?"
"No… "
"Holy shit, you can't even do it?"
First place in the province in the National High School Mathematics Competition!
He can't even do it? !
This guy doesn't play games in the dormitory. He just sits on the bed and reads some difficult books all day long.
However, after hearing that He Ping had not written it down, Zhou Xuan breathed a sigh of relief and was not as nervous as before.
What's the saying
D!
If one or two people didn't write, that's the problem of those one or two people. But if everyone didn't write, then it's not everyone's problem, but the problem with the topic.
He Ping was not as optimistic as his roommate. He Ping didn't even bother to talk to him. He continued to stare at the question in his draft book and meditate hard, as if he had got into trouble.
No wonder…
After all, no matter how you look at it, this is an extremely simple question.
But the strange thing is that he has tried everything, but he just can't do it!
Seeing the sad expressions of the students in the audience, Li Xuesong couldn't be too happy.
He never thought that these future coders could solve such a problem.
Ah!
I want you grandsons not to take my lessons seriously!
Do you know you regret it now
However, to be happy, the teacher’s dignity still needs to be displayed.
After trying very hard to squeeze out a trace of disappointment from his eyebrows, the balding old man comforted everyone with a pretentious tone.
"It doesn't matter if you can't write it out. You can hand it over as much as you write, at least let me see your thoughts. Class 1 Academic Committee, go and collect it, even if you just write an explanation."
After hearing these words, the students who were handing in homework finally got some movement, and hesitantly handed over the homework book with only one question in their hands.
There were also those who had never done homework before. They were even more relieved. They simply took the homework of their deskmate and copied the questions, and then wrote the solution in the blank space.
Looking at the homework that had been collected in less than a while, Professor Li Xuesong smiled inwardly, but he clicked his tongue and shook his head.
"Seeing that one or two of you didn't pay attention to the lecture, and some of you came late and left early, I thought you all had learned it. I didn't expect that not even one of you could solve such a simple question."
"Students of this class, I really don't know how you studied in high school!"
Hearing this sentence, all the students in the class looked ashamed.
To be honest, strictly speaking, no one who can sit in this classroom is a scumbag in the true sense of the word. Not to mention beating up the overseas friends recruited from the international class, but at least in mathematics, physics and chemistry, none of them scored low.
Therefore, such soul torture is undoubtedly a bit heartbreaking for them.
Especially for a certain top student who had won the provincial first prize and almost entered Shuimuyan University, it made him so uncomfortable that he wanted to bite off his thumb.
Why can't I write it? ?
This is so impossible!
Seeing that Lao Li on the podium had already opened the cover of the advanced mathematics textbook, he had no intention of talking about this question that he had been thinking about for half a week and couldn't figure it out. He Ping knew that he could not wait any longer, and suddenly started to answer. The chair stood up.
"Teacher, I want to know the answer to that question!"
Zhou Xuan, who was sitting next to him, was startled by his roommate's actions and quickly stuffed his phone into the drawer.
Wang Ziyi and Yuan Gaofei were the same, looking at He Ping blankly, wondering what kind of plane he was making.
Coincidentally, the same thing happened to Li Xuesong standing on the podium.
Upon hearing this question, the expression on his face suddenly froze.
"Answer, the answer? Haha, you can't answer such a simple question, you still have the nerve to ask me the answer," after all, Jiang is still hotter. Li Xuesong was caught off guard and showed a little timidity, but he quickly covered it up with a serious face. , and said, "I will give you the answer in a while, and you can think about it carefully."
When He Ping heard that he would have to wait a few days before announcing the answer, He Ping's originally emotionless face suddenly twisted with a trace of pain for the first time.
"Teacher! Please! Just tell me."
"Well, those who know how to talk will talk about it. In two days... I'll give you some time to think about it. Actually, this question is just for you to get your bearings. It is not the focus of our advanced mathematics class. Even if you don't know the answer-"
"I beg you! I haven't slept well for half a week..."
Seeing He Ping suddenly holding his head in pain, Zhou Xuanren sitting next to him was stunned.
Damn it
Is this crazy
There was a burst of ** in the classroom.
Many people started talking in confusion.
"Who is that person?"
"I heard he was the top student in class 1 who won the first place in the math competition!"
"Damn it! Why did Shu Jingsheng major in software?"
"Who knows, no matter what they read, don't you think it's outrageous to throw questions to us that we can't even save one grade on?"
"It turns out that people can really be driven crazy by mathematics..."
It wasn't just the people in dormitory 402 who were dumbfounded, Li Xuesong who was standing on the podium was also dumbfounded.
This guy…
Could it be that he was stimulated
I felt a little timid in my heart. This was the first time for the balding old guy to see this situation, so he hurriedly tried to change the subject.
"That classmate, I understand that you are very curious about knowledge, but please sit down first. We are going to class soon. If you have any questions, we can wait until after class. By the way, I forgot to call your name just now. Let's call your name now. …”
He Ping looked uncomfortable and still refused to sit down.
Obviously this guy was stimulated. Now he was not only fighting with himself, but also with the whole class.
Just when Li Xuesong hurriedly opened the roll call list, hurried footsteps suddenly came from outside the corridor.
Then the back door opened a crack, and a figure carrying a shoulder bag was seen trying to sneak in from the outside.
Of course Li Xuesong would not miss such an obvious big black rat.
If he usually turned a blind eye, college mainly relies on self-consciousness. Which teacher could be like the father and mother in high school
But who wants today to be such an unlucky day
It hit the muzzle of the gun!
Li Xuesong, who was worried about not having a chance to find a way down, suddenly turned his face into a chopping board, showed a different momentum, and shouted loudly like chopping meat and vegetables.
"The late one at the back."
"Stand up for me!"
The sound was like shouting from a trumpet.
Hao Yun, who had just taken a few breaths and was about to sit down when he pulled out his chair, almost couldn't catch his breath and was completely confused...
