The top-notch movie queen wears books, disguises herself as a man and is handsome all over the world

Anderson's tone was very exaggerated and very proud: "Of course, that was the great Professor John, but your Chinese geniuses are also very powerful. They solved Zhou's conjecture at the age of seventeen, and Professor John Wish was still in the academic seminar. It said that I am looking forward to meeting that young man from your country."

Qin Jingyu continued to ask: "So the academic lecture upstairs is Professor John Wish?"

As soon as he finished speaking, even Shen Tu, Chen Shaochuan and others became nervous. It was an honor to meet this great mathematician.

Anderson shook his head: "No, no, no, today's lecture is not Professor John. Professor John has not given a lecture for a long time except for the Zhou Conjecture seminar last month. Today is just a regular lecture for top students in the Department of Mathematics, but the topic very interesting."

Everyone couldn't help but feel disappointed when they heard that Professor John was not here. Qin Jingyu was also slightly disappointed, but she thought she would see him sooner or later.

So he asked again: "What is that interesting topic?"

"Twin Primes and Goldbach's Conjecture."

After saying that, He Qian expressed no interest. Chen Shaochuan finally reacted and looked up.

Qin Jingyu's eyebrows twitched. Sure enough, coincidences are everywhere in the world.

Shen Tu thought to himself, "Oh no!" and looked at Qin Jingyu. He had seen this kid studying twin prime numbers on the plane yesterday.

Sure enough, seeing the kid's eyes shining, Shen Tu coughed slightly and reminded that the purpose of coming to Princeton University this time was to compete.

After hearing Shen Tu's reminder, Qin Jingyu closed his shining eyes.

Before she could ask again, Chen Shaochuan asked: "Can we observe the lecture?"

Qin Jingyu couldn't help but look at Chen Shaochuan. Could this madman also be interested?

Anderson reminded: "This kind of lecture is open. Students from all departments of the school can attend it. If you want to attend the lecture, please bring your admission ticket and keep quiet."

Qin Jingyu raised his eyebrows. She couldn't hold it in any longer. Shen Tu held her shoulders and whispered, "Do business first."

Qin Jingyu shrugged helplessly, okay!

Then Shen Tu smiled and said to Anderson: "Please continue to take us to visit the school, thank you."

Princeton University covers an area of ​​several thousand acres. They spent nearly two hours and only visited less than half of it. Of course, the main purpose is not to visit the entire school, but to familiarize yourself with the distribution of the school and the examination room routes, so as to avoid not being able to find the examination room when the time comes.

The rest of the time was for free activities. After Shen Tu saw that they were familiar with the examination room and route, he waved his hand and let them go. Of course, he did not forget to remind someone that the competition was the real business.

Qin Jingyu privately promised not to delay the competition, so Shen Tu could rest assured that she would go.

Knowing that she was going to attend the lecture, Chen Shaochuan said that he would also go with her. He was also very interested in this lecture. He Qian saw that they both wanted to go. She was not familiar with the place in this university where top students gathered. There’s no point in going back to the hotel, so let’s go together and experience the learning atmosphere of Princeton University.

The three of them went to the lecture theater together and found that there were quite a lot of people coming to listen to the lecture. The lecture theater, which can accommodate hundreds or even thousands of people, was almost full. As far as the eye could see, almost all the lecture halls were filled with people.

Even though there were so many people, the entire classroom was very quiet, with almost no one speaking except the main speaker on the podium.

Finally, I found a few empty tables in the last row. After I sat down, I noticed someone I knew.

Of course, not an acquaintance.

He has brown amber eyes, very fair skin, and is wearing the blue and white uniform of Country K. He is the same Ethan whom he met in the hotel yesterday.

Unexpectedly, he also came to attend the lecture.

Ethan heard a voice next to him and looked sideways. After seeing the team uniforms on Qin Jingyu and others, he recognized them as players from the Chinese team and nodded slightly in a friendly gesture.

Qin Jingyu also nodded in return.

When He Qian saw Ethan up close, she just wanted to bark like a marmot, but she held on. Foreigners have racial advantages, especially K country, which is famous for its many handsome men and beautiful women. Their superior silhouettes and three-dimensional facial features are perfect. statues of gods.

Ethan is of mixed race, with Chinese blood, so he has an oriental softness about him, but he is also handsome enough to make his debut.

He Qian looked at Ethan, then at her teammate Qin Jingyu, and sighed, these two people are simply the representatives of handsome men from the East and the West. Look at Chen Shaochuan, a minority, wild and tough handsome, who can match such a There are many handsome guys watching the same lecture. Even if you don't understand, you will still make money just by admiring the handsome guys.

And He Qian really couldn't understand the content of the lecture. Her understanding of twin prime numbers and Goldbach's conjecture was very one-sided. Even the popular search about the Chinese genius boy solving Zhou's conjecture was popularized by the People's Daily. , and then I realized that there are so many awesome conjectures in mathematics.

She thought she was not the only one who didn't understand, so she turned her head to look at Chen Shaochuan and Qin Jingyu. When she saw the two of them focusing on each other, she realized that she was the only one who didn't understand! ! !

I had heard from Anderson that today’s lecture would be organized by graduate students from the Department of Mathematics, but when I arrived, I discovered that in addition to the students, there was also a professor from the Department of Mathematics at Princeton University.

It is written on the blackboard: Any integer greater than 5 can be written as the sum of three prime numbers, n>5: When n is an even number, n=2+(n-2), n-2 is also an even number, and can be decomposed into two The sum of prime numbers; when n is an odd number, n=3+(n-3), n-3 is also an even number...

This is Goldbach's conjecture.

On the other side is the twin prime conjecture.
