Chapter 56 Teacher?

Wu Tong is not arrogant enough to feel that at his level as a beginner, he feels that he can challenge the world's problems.

However, Wu Tong comprehensively completed the basics of each section of mathematics a few years ago. After coming to Peking University, he continued to study and research number theory, and naturally came into contact with materials and papers on various conjectures in several rounds of sections.

Of course, general problems do not bother Wu Tong. It would be false to say that Wu Tong is not interested in conquering the world's difficult conjectures. Anyone who studies mathematics has the ambition to conquer the world's conjectures.

She had just read and studied many books and papers on the number theory section. It was inevitable that she had also started an in-depth study of the prime number section. There were few people who studied number theory who were not obsessed with prime numbers, and she was not that exception.

Among integers greater than 1, a number that is divisible only by 1 and the number itself is a prime number.

The new development of twin prime numbers in later generations, which Wu Tong vaguely dug out from the memory of his previous life, should be 13 years ago. Mr. Zhang Yitang, who was teaching in country M at that time, proved that there are infinitely many pairs of prime numbers, and the difference is less than 7000 million.

Although 7000 million is a large number, this result holds true. It is the first time that someone has formally proved that there are infinite pairs of prime numbers whose distance is smaller than a certain value.

It's just that twin prime numbers get harder and harder as they go forward, and Mr. Zhang has only advanced so far!
The International Society of Mathematicians, through Mr. Zhang’s method, reduced the number 7000 million to 246. Mathematicians around the world who are interested in this want to keep trying. By selecting an appropriate function, they hope that one day they can The gap narrows to the number 2.

However, the step from 246 to 2 is still as high as a mountain, strangling mathematicians all over the world.

What is even more regrettable is that Professor Zhang still used mostly classical mathematical techniques, which were not very innovative and caused some controversy at the time.

At that time, because it was a breakthrough by a Chinese mathematician, domestic news headlines took turns to broadcast it, and Wu Tong was somewhat impressed by this.

If I remember correctly, Mr. Zhang used his improved sieving method at the time. Although Wu Tong has no way to break the conjecture of twin prime numbers, she already has an intuitive judgment based on the deduction instinct of the stele of enlightenment. According to the sieve method, this way is blocked!
Professor Zhang's contribution to the twin prime number conjecture is indelible, but he is still unable to complete the breakthrough of this world problem.

After Wu Tong carefully deduced the arguments of various methods in different papers, she had some ideas in the parts that had been deduced, and she wrote down a few more lines of formulas. This was an argument based on her own ideas.

She tentatively continued to deduce a few more steps, but the ideas were too scattered and could not be connected into a line. She still needed to continue to study and study.

The twin prime conjecture is indeed a world-class conjecture. When she is doing college questions now, there is basically no stumbling, extracting the question stems, and her thoughts are smooth. Faced with this problem, she still deeply feels the lack of knowledge. The road is bleak.

Wu Tong didn't intend to eat a big fat piece of paper in one bite. No matter how difficult the question was, there was always an answer. She couldn't give the answer now. It could only be that she didn't learn enough.

Holding the draft paper for the deduction, Wu Tong stood up and wanted to find more information in this area, the sieve method, the round method, Li Qun?still···

Wu Tong's mind was still immersed in constant deductions, and all walking was left to instinct.

It's only the fifteenth day of the first lunar month, and there are still a few days before the start of school. There are very few people in the Beijing University Library, and the mathematics section is even rarer.

Every time Wu Tong came, it was almost always at a fixed location, and the route was so familiar that he could reach it with his eyes closed.

Wu Tong, who was still immersed, instinctively walked to the bookshelf she wanted, and was about to go around to the other side to get the information she saw.However, when she turned a corner, Wu Tong, who didn't expect there to be anyone else in the area, discovered that there was someone on the opposite side who had the same goal as her.

The lights in the library lengthened the tall figure of the visitor, and also cast a faint shadow of Wu Tong at this end.Wu Tong and the visitor stopped in time and sidestepped each other to avoid an unprepared collision. However, in the critical moment, the draft paper in Wu Tong's hand fell to the ground like snowflakes.

"Sorry, I wasn't paying attention when I was walking, didn't I bump into you?" It seemed like she almost bumped into someone?
Wu Tong came back to his senses in shock, his first reaction was to apologize, he shouldn't let indulging in deduction just now, occupy all his attention, and believe in instinct.

As she raised her head, a cold and sharp face appeared in Wu Tong's eyes. She was stunned for a rare moment. This was an outstanding face that could cause a [-]% turn-around rate when someone walked out casually. In ancient times, it would have definitely turned heads. Able to throw fruit and profit carts.

However, although Wu Tong has not yet reached the saintly state of Lanyan Skull, except for the surprise of seeing beautiful things, she is not too obsessed with it. She is very calm. The beauty of mathematics has occupied her life except for her family. Thoughts.

After apologizing, Wu Tong knelt down to pick up her draft paper.

Lu Xiao pinched the center of his brows lightly, and a pair of gold-rimmed glasses hung on his tall nose bridge, which added a three-pointed elegance, calmness and profoundness to him.

It was also he who lost his vigilance, bent his knees and squatted down, collected the draft paper beside him, and picked it up. A series of derivation formulas came into his eyes. Is this...a prime number?

"I was also distracted! A special form of the twin prime number conjecture under the Ponia Conjecture? Can't you go on with the sieve method?" After glancing at the top-level derivation formula, Lu Xiao handed the draft paper in his hand to Wu Tong, and Lu Xiao slowed down In a tone of voice, he asked softly.

The delicate eyebrows moved slightly, how long has he been out of the laboratory?Have the children of today begun to challenge the conjectures of the world?
Wu Tong still has a childish face, which can be seen at a glance. Which professor's child is this?The origins of family education and the successors are there!

"Yes, sir!" Wu Tong couldn't define the identity of the person opposite, so he chose to use the honorific title of sir.

Said to be a senior with a graduate degree or above, intuitively, the temperament of the person opposite is not quite like a school student!It is said that it is a professor from Peking University, but the age of the person opposite seems a bit too young!However, youth is not the criterion for defining a person's ability. She can see her research direction from a few messy derivation formulas at a glance. The person on the other side has a strong mathematical foundation. It should be the person she has seen so far with the strongest mathematical foundation. that's it!
Lu Xiao pondered for a moment, then gently pushed the glasses on the bridge of his nose.

"Perhaps, the way is beyond the sieve method. Hibbert's topological method to prove that prime numbers are infinite. Perhaps, you can try this direction?"

Lu Xiao raised his hand, took down a book from the top of the bookshelf and handed it to Wu Tong, "This is Zellberg's supplementary research on sieve theory using topological methods. I hope it can inspire you!"

Topology?What are some properties of geometric figures or spaces that remain unchanged after continuously changing shape?

In an instant, the distance between the library's lamps, the bookshelf, and the people opposite seemed to constitute the golden triangle ratio in the spatial composition. From the perspective of the viewer, pure geometric images rotated in Wu Tong's mind, and the soft light of the enlightenment stele spread out. .

Ripples of thoughts rippled in Wu Tong's mind, and white doves seemed to fly away with inspiration. She seemed to have grabbed a little bit of silk that could string the broken chain into a beautiful pearl necklace.

"Thank you, teacher!" Wu Tong borrowed the book to thank him.

She determined that such a level of knowledge was basically not something that ordinary students could possess.With the gentle guidance, the layer of fog that had just shrouded her eyes was lifted away, revealing a little light.

Even if she guesses wrong, it doesn't matter. A person who knows something is a teacher. Being able to give her guidance is enough to prove that someone's knowledge is better than hers. A person who knows something is a teacher. It's not a bad thing to call her a teacher!
