When I am reborn, I just want to be a top student

After saying that to the outside world, Wang Donglai no longer paid attention to information from outside.

Instead, he was busy with one thing, which was to develop an exam registration system.

At the same time, Wang Donglai also plans to record the answers to the questions he prepared this time in the system. In this way, he can also pass the initial screening by the machine and save a lot of energy.

After all, they are recruiting graduate students themselves. Now that it has become a big deal, there must be many people who will choose to sign up for the two hundred thousand yuan.

When the number of people increases, it becomes troublesome to review the test papers.

It just so happens that we can use high-tech technology to solve this problem.

As for whether anyone would cheat in the open-book exam, Wang Donglai was not worried about that.

Because mathematics is different from other majors, if you know it, you know it, and if you don’t know it, you don’t know it.

The test paper he will give this time will not have many questions, only three.

But these three questions were specially thought out by him. If you don’t reach the mathematical level that he approves of, it would be impossible to solve them.

Even if someone could do it easily, his or her status would have to be at least a mathematics professor.

Such a scholar would naturally not help others cheat for the sake of two hundred thousand yuan.

The reason is very simple. After taking the written test, Wang Donglai will also conduct an interview.

If you perform poorly in the interview, it means there is a problem with the written test. If news of cheating comes out at that time, it will be more trouble than gain.

not to mention.

Wang Donglai also had another idea, which was to make the test questions this time a little more difficult, with the purpose of testing rather than selection.

With this thought in mind, Wang Donglai kept moving.

A simple system for registering for the exam was quickly written.

After completing the system, Wang Donglai did not hesitate and sent it directly to the office of the president of Tangdu Jiaotong University.

This time, the registration is handled by Tangdu Jiaotong University.

After all, recruiting graduate students is an academic matter, and it is somewhat inconvenient to let Galaxy Technology handle it.

After obtaining the registration system, Tangdu Jiaotong University asked for instructions and immediately announced the news to the public.

soon.

The number of applicants increased rapidly.

Among them, there are those who really want to be Wang Donglai's graduate student, and there are also many who are just filling in the numbers for fun.

Ten thousand!
fifty thousand!

One hundred thousand!

As the number of registrations soared to 100,000, it sparked another wave of discussion.

"The latest news is that the number of applicants has exceeded 100,000. The competition is too fierce!"

"In my opinion, 100,000 people is probably not the limit. It may even increase further!"

"There are millions of applicants for graduate school every year. One hundred thousand is just a drop in the bucket!"

"I heard that there are only three places for graduate students this time. Doesn't that mean the rest of you will just be cannon fodder?"

"Let me be honest. Among the 100,000 applicants, 5,000 of them are math majors, which is already considered high. I estimate that 99% of them choose to sign up just for fun."

"I can prove that I am one of the 100,000 applicants. The reason I chose to sign up is to witness how difficult the questions Wang Donglai set are."

"It's an open-book exam, and they claim that as long as you pass it, you can get 200,000 yuan. I want to see how many people can get this 200,000 yuan!"

"If I change to another professional field, I guarantee that I can broaden Wang Donglai's horizons!"

"Why call me Wang Donglai? Call me Wang Shen!"

"I regret that I was born a year earlier. Now I am a second-year graduate student!"

"I'm more curious about what the questions will be like in the test paper. Will they come up with a world-class problem?"

"..."

There are all kinds of people on the Internet, and there are all kinds of comments.

In the field of mathematics among universities, there is also great attention paid to Wang Donglai's recruitment of graduate students.

Mathematics is different from other majors. If you are talking about undergraduate studies, you may just choose a major randomly after the college entrance examination, or it may be a decision made in the heat of the moment.

But when I reached graduate school, I really fell in love with mathematics.

Moreover, I have great talent and can develop in the field of mathematics. Otherwise, I would not be able to pursue postgraduate studies.

Who is Wang Donglai?

He became famous overnight in his twenties!

It has won many top international awards and received important honors in other fields.

Adams Chemistry Award, Second Prize of National Science and Technology Progress Award...

The world's difficult mathematical problems proved by Wang Donglai include the ABC conjecture, Zhou's conjecture, the distribution law and precise formula of Mersenne prime numbers, etc.

Among them, Wang Donglai's ideas for proving difficult mathematical problems are still being studied, and the continuous publication of papers is proof of this.

The old "Emperor of Mathematics" Grothendieck has passed away, but in the eyes of many people, Wang Donglai is a new sun that is about to rise.

Again.

Too young!
Otherwise, the mathematics academic circle would have long been dominated by Wang Donglai.

Now, I heard that Wang Donglai is going to recruit graduate students.

This means that as long as you are selected by Wang Donglai this time, you will be the first batch of students under Wang Donglai, and the relationship will naturally be the closest.

It not only represents academic progress, but also represents the improvement of academic status.

Just write Wang Donglai's name on your paper or resume and you will receive super-standard treatment.

So, this led to a very embarrassing situation.

That is, for this registration exam, not only senior students are signing up, but even some first- and second-year graduate students are also interested.

The brave ones mustered up the courage and carefully raised the issue to their mentors.

Surprisingly, faced with such a situation, the instructors were very easy to talk to. They first agreed to the registration and then reported the matter to their superiors.

Finally, the universities communicated with each other and reported to the competent authorities.

After an urgent discussion, the universities received a reply that students would not be prohibited from registering for the exam and everything would be decided after the exams.

……

Yanda, School of Mathematical Sciences.

Wei Shen walked to the door of the dean's office, knocked gently, and then pushed the door open and walked in.

Tian Gang in the office was busy handling matters at his desk with his head down. When he heard the sound of the door being pushed open, he looked over.

"Dong Yi, why are you here? Have you finished the homework I assigned to you? That's great. I have another question I just wrote in my hand. You can take it and review it!"

Tian Gang said this and prepared to take action.

At this time, Wei Dongyi spoke up and said, "Teacher, I want to sign up to see what kind of questions Professor Wang will ask. I can also take this opportunity to see how big the gap is between me and my peers."

In fact, Tian Gang thought of this when he saw Wei Dongyi coming in.

As the dean of the School of Mathematical Sciences of Yan University and an academician of the Chinese Academy of Sciences, Tian Gang’s IQ cannot be bad.

Before Wang Donglai came out of nowhere, Tian Gang had always been very satisfied with Wei Dongyi's performance. He had shown an IQ above average since he was a child, and he had a special talent for mathematics.

After entering university, he was no longer obsessed with material things. He would sit in the library all day with a bucket of water and a few steamed buns. His attitude towards learning was very serious.

Therefore, Tian Gang decided early on to accept Wei Dongyi as a graduate student, and to allow him to study for a master's and doctoral degree simultaneously.

However, when Wang Donglai appeared out of nowhere.

Wei Dongyi's performance is a bit disappointing. In terms of academic achievements, the two are not at the same level at all.

At that time, Tian Gang had thought about recruiting Wang Donglai to Yanda, but Yanda and Wudaokou tried twice but failed to accomplish this, so he gradually gave up the matter.

However, Tian Gang still chose to recruit Wei Dongyi as his student to study for a master's and doctoral degree simultaneously.

Wei Dongyi is three years older than Wang Donglai, but their achievements and status in the academic field are very different.

Now that Wang Donglai wants to recruit graduate students, Wei Dongyi naturally cannot remain indifferent.

Therefore, Tian Gang was not surprised to hear Wei Dongyi's words.

"I knew you would come to me."

"Being able to study with Wang Donglai is also a good opportunity for you."

"I have to admit that Wang Donglai's academic achievements far exceed mine. You are all young people and have more common topics. If you study with him, it will be more helpful to your future!"

When Tian Gang said this, Wei Dongyi spoke up and said, "Teacher, I don't plan to change my mentor. I just want to see the gap between me and him. It would be best if I could communicate with him more and learn from him."

Hearing what Wei Dongyi said, Tian Gang didn't show it on the surface, but he secretly breathed a sigh of relief in his heart.

In fact, he was not willing to send his students abroad.

"Actually, this is very simple. In two days, Professor Wang will come to Yanda for exchange and study, just like he did in Wudaokou in the first half of the year. I can make some arrangements then, and you can just follow him and learn well!"

"You should also prepare well for this registration exam and get a good score when the time comes."

Wei Dongyi nodded and said, "Well, I will do my best!"

"Okay, then go down and get ready!"

Tian Gang waved his hand, signaling Wei Dongyi to go down.

Watching Wei Dongyi go down, Tian Gang shook his head, sighed softly, and his expression was a little complicated.

“The waves behind the Yangtze River push the waves ahead!”

……

There are only two days to register.

The exam officially began at twelve noon on the third day.

Because it was an open-book exam, the test questions were released shortly after the exam started.

There are three questions in total.

In the first question, "Can a chair be placed steadily on an uneven ground?", change the line connecting the four legs from a square to a rectangle, and keep the rest the same. Try to construct a model and solve it.

When this question was circulated, many people read it several times but still did not understand what it meant.

And that's not even the most important thing.

The most noteworthy thing is that this question is specially marked with a label of "simple and easy question".

Yes, this label appears directly on the test paper.

For the second question, the label changed to 'slightly difficult'.

Disks with a certain radius are processed using rectangular plates of known size. Several simple and effective arrangement methods are given to process as many disks as possible.

As for the third question, it is even simpler.

Use a ruler and compass to construct a square whose area is equal to the area of ​​the known circle.

As soon as these three questions were asked online, they attracted great attention.

however.

As time goes by, no one has said anything useful about these three questions.

As for the reason, it couldn't be simpler.

In 2015, the bachelor's degree rate in my country was still 1.6 per thousand, which means that only three people out of two thousand people had a bachelor's degree.

The number of people with master's and doctoral degrees is even smaller.

As for the three questions Wang Donglai asked, if you are not an undergraduate majoring in mathematics, you probably won’t even be able to understand them.

It can even be said that students majoring in professional mathematics are just scratching the surface.

If you want to solve it, or solve part of it, it depends on your real ability.

After all, this exam is an open-book exam, and you can go online to look up information and read papers.

Since such conditions can be given, it means that you have absolute confidence in these three questions.

When people who know the subject see these three questions, they frown at the first moment.

There is no other reason, it’s just too difficult!

Each question is more difficult than the last.

If you can solve the last question, you can publish it directly in the top international mathematics journals, no pressure at all!
And you will get some awards for it.

From this we can see how difficult the three questions Wang Donglai asked this time are.

To be honest, Wang Donglai considered the difficulty when he wrote these three questions.

This was also intentional on his part.

After all, he was recruiting graduate students who came to learn from him, not scholars to discuss academic matters with him.

The increased difficulty is mainly to be able to see the candidates' thinking and process of solving the questions, so as to make accurate judgments and select candidates with potential.

As for those who joined in the fun, Wang Donglai didn't consider their psychological trauma at all.

After seeing these three questions, netizens paused for a while before speaking out.

"I know every Chinese character, why don't I understand their meaning when they are combined together?!"

"Don't talk about you. I was the same. I watched it over and over again, but I didn't understand it at all!"

"I finally understand why we dare to take open-book exams. For questions like this, even if I were asked to copy, I would have nowhere to copy!"

"A large reward for the top student. I am willing to offer a reward of 100,000 yuan for the solutions and answers to these three questions. I will never regret it!"

"I'll offer a reward of 150,000 for the answer and the solution. As long as it can help me pass, the price is negotiable!"

"My goodness, all the abacus beads are flying!"

"I have a piece of inside information. I heard that the higher-ups intend to let Professor Wang be the one who sets the questions for this postgraduate entrance examination. This means that this year's postgraduate entrance examination questions may be set by Professor Wang!"

"It doesn't matter. I just don't believe that anyone can solve such a problem. Whether everyone can do it or no one can do it, the result is actually the same!"

"Real-name verification, I'm a graduate student in the Department of Mathematics at Shanghai Jiao Tong University. I just looked at these three questions and my mind is broken. I have no idea at all!"

"It's over. If my professor knew that I couldn't even solve the first, the easiest of the three questions, I would probably have to delay my graduation!"

"Strongly condemned, professional players are not allowed to participate!"

Various comments have made the difficulty of the test paper a hot word on the Internet platform. (End of this chapter)
