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

on Monday

Shen Tu personally drove to Qin's house to pick him up. Sitting in the back of the car were Chen Shaochuan and He Qian. Neither of them were from the Imperial City. After the training camp, they had been arranged to stay in a hotel for the past two days.

The old man and Aunt Tan saw Qin Jingyu out, and Shen Tu helped put the luggage.

He Qian looked at the luxurious Chinese-style Qin House and couldn't help but sigh: "Qin Jingyu's family is so rich, the garden is so beautiful, and he has good grades and is handsome."

She didn't want to be a nymphomaniac, but Qin Jingyu was really handsome. She heard that during the basketball game on the last night of the training camp, many girls secretly took photos of Qin Jingyu dunking for her collection.

Chen Shaochuan glanced outside and then looked away.

What does the rich have to do with him?

Qin Jingyu said goodbye to Qin Hao and Aunt Tan, got into Shen Tu's car, and greeted the two people in the back row.

Shen Tu got into the car and said, "Let's go, fasten your seat belt."

The group arrived at the airport. The people accompanying them from the Hua Guo team were waiting for them early. After Assistant Wang took out the tickets and gave them to Qin Jingyu and others, he also gave two sets of clothes to the three of them.

The bright Chinese red and the flag on the chest all represent China.

He Qian directly said that she thought the team uniform was a bit ugly. Qin Jingyu remained neutral and said nothing. Chen Shaochuan didn't care. Anyway, it looked better than the white T-shirt he was wearing, and he could get two pieces of clothing for free.

Shen Tu explained: "This is a custom-made team uniform. You can put it on when you arrive in country M. This is an old tradition of our national team."

When He Qian heard it, it turned out to be the uniform of the national team. Looking at it this way, the clothes instantly had a patriotic filter. They were not ugly at all, they looked pretty good.

After Qin Jingyu stuffed the clothes into the suitcase, he checked the luggage in. Soon it was time to board the plane.

On the plane, Qin Jingyu's seat was next to Coach Shen Tu. His mobile phone was turned off on the plane, and he habitually took out the "Collection of Ancient and Modern Mathematical Thoughts" and manuscript paper that he brought with him.

Shen Tu inadvertently glanced at the formula of (p, p + 2) and k=1 on her manuscript paper. After being stunned for a moment, he pushed up his glasses and asked, "Twin prime numbers?"

Qin Jingyu closed the book and replied, "Well, I've been interested in it recently."

"It's guessed by the Zhou family..." Shen Tu said this and stopped for a moment, but Qin Jingyu became nervous. Shen Tu said slowly, "It's different but similar in approach."

All require understanding of the distribution of prime numbers.

Qin Jingyu glanced sideways at the young head coach next to him, "Coach Shen, do you know something?"

Shen Tu smiled slightly, "I don't know anything, but it is an honor for me to be your head coach."

They are all smart people.

Qin Jingyu was so smart, and Tang Yuxin was full of praise for the cat-and-mouse digital game he developed. Although the National Institute of Nuclear Science and Technology claimed that the genius boy who solved Zhou's conjecture was a talent of their mathematical research center, there are people with the same name and the same surname. A mathematical genius, he is now interested in twin prime numbers. What a coincidence.

Since someone is deliberately covering up, why should he expose it?

Besides, Qin Jingyu is no less talented in physics than in mathematics.

Therefore, he is honored to be the bishop of this young man who is known as a mathematical genius in China.

Shen Tu's words were not stated clearly, but there were hints everywhere. Qin Jingyu knew that he had lost his horse in front of the other fox. There was no explanation and everything was left unspoken.

They flattered each other and said, "I am also honored to be your coach's student."

……

During the remaining time, Shen Tu did not disturb Qin Jingyu, and Qin Jingyu returned to thinking.

The twin prime conjecture is the guess that there are infinite pairs of twin primes, but whether there are a finite number of twin primes or an infinite number is still an unproven problem.

She had read about the process of proving Goldbach's conjecture in the past two days. After all, they said that twin prime numbers are similar to Goldbach's conjecture, and the two are the same.

She had been misled in this way before, but after reading it, she realized that there was no direct connection between the two.

It is just a study of twin prime numbers and Goldbach's conjecture. The focus is not on proof, but on improving the theory of prime numbers. If Goldbach's conjecture was used to prove twin prime numbers, it would be too complicated and would require a lot of detours, and the results could not be guaranteed to be correct, so she passed the idea.

She used the sieve method used to prove Zhou's conjecture on twin prime numbers and found that it did not work.

She also asked Heliancheng for advice, and he said that the first method that came to mind was to use the method Euler used when proving that there were infinitely many prime numbers.

Maybe she could really try the method He Liancheng said.

她开始在稿纸上写下，设所有的素数的倒数和为：s=1/2+1/3+1/5+1/7+1/11+…

If there are a finite number of prime numbers, then the sum of the reciprocals is naturally a finite number.

Euler proved that this sum is divergent, that is, it is infinite, which shows that there are infinitely many prime numbers. Can she use this method to find the reciprocal sum of twin prime numbers?

她没有迟疑，继续在稿纸上写着，B＝（1/3+1/5）+（1/5+1/7）+……

Qin Jingyu was brainstorming rapidly, and by the time the voice announcement was made that the plane was about to land at an airport in Country M, her manuscript paper was already full of several large pages.

Seeing the final result, Qin Jingyu frowned dissatisfied. This countdown was a finite number.

it is wrong!

There is a very accurate general formula for twin prime numbers, which is based on a theorem: If the natural numbers q and q+2 are not divisible by any prime number not larger than the root (q+2), then q and q+2 are a pair of prime numbers, are called twin primes differing by 2.

This sentence can be expressed by the formula: =plm1+b1=……

Suddenly, she thought of something and continued to write that if she, for example, when k=1, q=2m+1, the solution is q=3 and 5, 5<32-2, then 3 and 3+2...and thus get 3 All twin primes in the square interval up to 3.

When she wrote this, it seemed that the number that had been bothering her for so long finally cleared up and she continued to write, k = 2 hours...

Suddenly, he was tapped on the shoulder.

Shen Tu glanced at her dense manuscript paper, couldn't help but sigh in his heart, and reminded: "We're here."

Qin Jingyu nodded and put away his pen. She has now found a clue to prove the twin prime conjecture, and she is not in a hurry.

Put away the pen and paper and get off the plane.
