Regarding mathematics, there is such a long-standing saying, it is like this, "mathematics is the queen of natural science", the meaning of this sentence is very easy to understand, whether it is physics, chemistry, or even biology, it is inseparable from the progress of mathematics, especially the theoretical progress of physics and chemistry, which is accompanied by the progress of mathematical theory, it can be said that without the support of mathematics, all other natural sciences will be eclipsed.

In the mathematical community, there is also such a saying, that is, "number theory is the crown on the head of the queen of mathematics", which concisely explains the importance of number theory in the discipline of mathematics, especially in the 21st century, the emergence of many side disciplines of mathematics is actually a derivative of number theory, it can be said that number theory has enriched the depth of mathematics.

As for the Goldbach conjecture, there is another saying, "The Goldbach conjecture is the brightest pearl in the crown".

So to put it together, it is said that mathematics is the queen of all natural sciences, number theory is the crown on the queen's head, and the Goldbach conjecture is the brightest pearl in the crown.

Since 1742, Goldbach put forward such a famous conjecture in a letter to the great mathematician Euler at that time, more than 300 years have passed, and no one has been able to give the complete proof process of this conjecture so far, only a few mathematicians through their own efforts. Step by step, it is approaching the final conjecture.

Goldbach's conjecture is actually quite simple, with only a dozen words: any even number greater than 2 can be written as the sum of two prime numbers.

But it is such a simple description that many mathematicians have not been able to come up with a proof process throughout their lives. Even Euler at the time admitted in a reply to Goldbach that this proposition seemed to be correct, but he could not give a rigorous proof. At the same time, Euler proposed another proposition: any even number greater than 2 is the sum of two prime numbers, but he did not prove this proposition.

At present, there are four ways to study Goldbach's conjecture, namely primes, exception sets, the three-prime theorem for small variables, and the almost Goldbach problem. One of the most common is the prime-numbering method.

We can often say that Chen Jingrun proved "1+2", in fact, he refers to the prime number method, using the prime number method, Goldbach's conjecture will eventually prove the problem of "1+1", but unfortunately, so far it has only reached the level of "1+2", and no one can give the follow-up proof.

Some time ago, a high school student on Zhihu used a few pages to claim that he had proved Goldbach's conjecture, which once caused heated discussions on Zhihu, but it was soon proven that his proof process was incorrect, and the matter was over.

But throughout the ages, the proof of Goldbach's conjecture has never stopped.

The teacher's inadvertent suggestion made Tao Li suddenly realize that although Yang Zhongming's seven major problems in world mathematics are also very challenging, compared with the Goldbach conjecture, Tao Li is obviously more inclined to the latter, because the Goldbach conjecture is too famous.

Many people may not have heard of any of the seven problems, but Goldbach's conjecture is familiar, and no matter how bad it is, the "1+2" proved by Chen Jingrun is also known to many people.

"I see, thank you. Tao Li quickly made a decision in his heart, since he wanted to do it, then make a big news!

Goldbach conjecture, that's it!

"No, what are you going to do, Mr. Tao, why are you so mysterious?" Seeing Tao Li so excited, Yang Zhongming became more and more curious, and couldn't help but ask again.

"I'll tell you later, I don't have a score in my heart for the time being. Tao Li smiled mysteriously, but still didn't announce the news to everyone.

Although there is a system, but Goldbach's conjecture is a super problem that has plagued mankind for more than three hundred years, even if he redeems his points for its proof process, Tao Li probably won't be able to understand it for a while, let alone teach these processes to others, or wait until he understands it.

"Teacher Tao is definitely planning something big again!"

"The level has reached the point of Goldbach's conjecture and the seven major problems, is this matter a little too big?"

"I can't imagine it, if this is announced, is it that Mr. Tao is no longer at the same level as us?"

"It's just like Teacher Tao is on the same level as you now! Teacher Tao won't dump you a few streets!"

…………

Seeing that Tao Li was silent, the rest of the teachers couldn't help but start laughing.

Tao Li just smiled and didn't answer, because next, he really wanted to do a big deal!

Now that the specific direction of research has been chosen, the next thing Tao Li has to do is to find the students to train. It is definitely inappropriate from the current high school sophomore class, after all, they are only high school students, and their theoretical knowledge is too different.

And at present, the most suitable ones are naturally Zhang Xingchen and Zheng Tongya, who have graduated from Yenching University and returned to school. The content of the two of them in undergraduate studies is mainly mathematics, coupled with Zhang Xingchen's solid mathematical skills and super scientific research spirit, it is the most suitable to choose the two of them.

In this way, Tao Li immediately summoned Zhang Xingchen and Zheng Tongya and came to the conference room next door.

"I'll just say that I came to you two to guide you to complete a paper, a paper that is enough to shake the entire mathematical community. Tao Li sat opposite the two of them, and said with a blazing look in his eyes.

"Papers?"

"And it's a paper that shook the entire mathematical community?"

Zhang Xingchen and Zheng Tongya glanced at each other, and they both saw the surprise in each other's eyes. They have known Tao Li for so long, and they know that Tao Li is not the kind of person who makes a lot of nonsense, since Tao Li told them so, it means that he must be sure again.

And writing papers, Tao Li is not the first time to guide them, when they were still in high school, Tao Li guided them to publish papers.

"That's right, but the amount of information in the question is a bit large, I'm afraid you can't bear it. I don't know if you're mentally prepared. Tao Li deliberately sold a pass and said.

Zhang Xingchen and Zheng Tongya became more and more curious, what is so mysterious?

"Teacher Tao, just say it, no matter what you say, the two of us are also people who have seen the world. Zhang Xingchen smiled and said.

"yes, how much information can be there! I'm OK with the stars. Zheng Tongya also patted his chest and said.

"Then I'll leave it at that. Tao Li took a deep breath, then looked at the two people, and said solemnly,

"This time I want to take you to write a paper in the direction of proving the Goldbach conjecture. ”
