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

Although there is a difference in age between the two, they have the same views on mathematics and arithmetic, and it is a shame that they met so late.

So Qin Jingyu nodded without hesitation, "Of course."

John Wish found two more goblets, Qin Jingyu poured red wine, clinked the glasses, and said, "Taste how it tastes."

Qin Jingyu tasted the Chinese food made by Felice and spoke highly of it, but after all, it was from abroad and the ingredients were different, so after all, it was not as good as the domestic food.

After listening, John Wish said: "Hahaha, if I have the chance, I will definitely go to your country of China, not for anything else but for the delicious food of your country of China."

In country M, which is known as a food desert, she is very confident in Chinese food. "I believe that Professor, when you go there, you will definitely live up to your expectations for food."

……

After drinking and eating, Professor John invited Qin Jingyu to his study.

There was a room full of books and documents, as well as many masterpieces by John and his teacher. She was like a mouse in a rice vat, dazzled.

Professor John originally studied number theory, and the Riemann Hypothesis belonged to analytic number theory. She thought that it was impossible for Professor John not to do research in this area.

Sure enough, when she asked, Professor John led her to a bookshelf like a child offering treasures.

All of the above are about various materials collected by Professor John about the world-famous mathematical problem Riemann Hypothesis, as well as his own research results. However, overcoming the Riemann Hypothesis has always been a big problem of the century, even for Professor John Wish. , I did study the Riemann Hypothesis in the early years, but I gained very little, so I left it there.

"So, after Zhou's conjecture was solved, you have been studying the Riemann Hypothesis, but you accidentally solved the twin prime numbers?" John Wish asked in surprise.

Qin Jingyu scratched the back of his nose, "That's true, but it's not an accident. There are similarities between twin prime numbers and the Riemann Hypothesis."

John Wish was shocked at how smart his mind was. It seemed that the future academic world would definitely be the battlefield for this Chinese boy.

However, he agreed with Qin Jingyu's words, "Qin, have you ever thought that all mathematical problems have something in common."

Since it is a difficult problem composed of numbers, how come they have nothing in common?

While Qin Jingyu was stunned, Johannwish continued: "After Riemann completed his studies at the University of Gottingen, he went to the University of Berlin. At the University of Berlin, he received guidance from many world-class mathematicians, especially Dirichlet's He has the greatest influence.

Later, he returned to Gottingen University and began to write a research paper about him. He met my teacher's teacher again. "

Having said this, John Wish found it very interesting, smiled, and continued: "Later, under the guidance of my teacher's teacher, the paper was completed very smoothly. At that time, a revolution in mathematical concepts was approaching its climax, and mathematics The focus is no longer on calculations, but on systematically understanding abstract concepts..."

The so-called function is a rule, and this rule does not necessarily require algebraic formulas to specify. As long as the rule takes a certain type of object and generates a new object from it, it is a function.

There is no need for John Wish to tell what happened later. Qin Jingyu also found out when he checked the information. Later Riemann published a paper entitled, "On the Number of Prime Numbers Less than a Given Value" and proposed "Riemann guess"

In one of the problems, a mathematician proved that there are infinitely many prime numbers. Another type of problem about the law of prime numbers is very difficult, and two of them have not been solved. They are the twin prime conjecture and Goldbach's conjecture.

Goldbach's conjecture has been proven long ago, and only twin primes are left. Now, the twin primes were also solved by Qin Jingyu two days ago.

Although it has not yet been compiled into a paper and sent to SCI for review, John Wish, as one of the anonymous professors reviewing the journal, has witnessed the entire process of unraveling the conjecture.

From the perspective of his professional knowledge, Qin Jingyu's proof process was perfect. And he had to lament once again that even he could hardly compare with this seventeen-year-old boy's use of the sifting method.

It was another long night of talking, and Professor John seemed to have regarded Qin Jingyu as his old friend. It was not until the sky was bright outside and Phyllis came over to clean up and make breakfast that the two of them ended.

She gained a lot from this night's communication. If it weren't for this opportunity, she might still have to go around in circles on the Riemann Hypothesis, so even if she didn't sleep all night again, she was still energetic.

However, Professor John was an old man in his sixties and couldn't bear to stay up late all the time, so after breakfast, Qin Jingyu said goodbye.

But before leaving, she took the liberty of asking Professor John for a signed book of his own works.

Professor John invited her to come back tomorrow. Qin Jingyu regretfully told him that she had stayed in country M for a few more days and booked a flight to return to the country tomorrow.

After Professor John learned that she was going back to China tomorrow, he was very reluctant to leave her. After all, Qin was from China. Once she left, he didn't know when he would see her next.

But Qin Jingyu didn't think so. She believed that she would become a student at Princeton University before too long, but she had not told Professor John Wei about this yet. It would surely be a surprise when she came to Princeton.

After leaving John Wish and returning to the hotel, she was not in a hurry to catch up on her sleep. The exchange last night made many ideas pop up in her mind. She didn't know if this would have any effect on solving the Riemann Hypothesis.

-

After staying up for two long nights, Qin Jingyu fell asleep wearing an eye mask on the plane back to China. He only woke up when he landed.

Putting the baseball cap on his head, he got off the plane and walked out of the airport. When he was about to call a taxi, he met an acquaintance outside the airport.

The other party shouted: "Master Jingyu."

"Uncle Yi." Qin Jingyu subconsciously looked around, but did not see a familiar figure.

Yi Zheng seemed to have guessed who she was looking for. Yi Zheng smiled and said, "No need to look for it. Mr. Bo is waiting for you in the parking lot."

She was stunned and asked doubtfully: "Is it such a coincidence?"

Bo Hanting also just returned to the Imperial City?

Yi Zheng: "No. Mr. Bo made a special trip to pick him up at the airport."

"How did you know about my flight?" No one had told anyone except Professor John about her return to China today.

Yi Zheng: "Master Jingyu, it's too easy for us to obtain your flight information."

She frowned slightly, but she said nothing and followed Yi Zheng to the parking lot.
