I'm the top student in Conan, but I'm actually an onmyoji.

“Do these big shots like to test juniors so much? "

Sagawa Yan complained in his heart. He also knew that his disadvantage was caused by his young age. Unless he showed his hard power to prove himself, this kind of doubt would always exist.。

“Master Shimura, please come up with the question," he said confidently.

Ishida looked on anxiously. In the Sakura Country, where hierarchies are obvious, Goro Shimura, as a teacher, spoke, and he was not qualified to object.。

“Sagawa, come on. "

Master Shimura walked to the blackboard, thought for a moment, and scribbled down the topic, "Prove that when 2^ (2^n) < P < 2^ (2^ (n + 1)), MP has 2^ ( n+1)-1 are prime numbers, and the relationship between P and n is the maximum and minimum...”

This question is the first step to prove the conjecture raised in the paper.。

“Master Shimura, what are you doing??”

“I think your conjecture is very likely to be correct, so don’t you want to prove it yourself? I can only take the first step to solve the problem of Mersenne prime numbers for you. "

Shimura Goro's kind smile returned to his face and he encouraged.

Sagawa Yan stood in front of the blackboard and let this test test what he had learned in three years. He

picked up the chalk in his right hand, his thoughts were empty at first, and then suddenly focused, As he started writing vigorously, the infinite prime numbers were magnified infinitely under his writing on the blackboard, and they were infinitely condensed in the line of expressions.。

“I see them, they are there, waiting to be discovered! "

The rules among prime numbers, the relationship between maximum and minimum, and the derivation process gradually became clear on the blackboard. Ishida on the side was a little confused, but Goro Shimura nodded

repeatedly and looked at Yan Sagawa's back. Also full of appreciation, the figure of a senior slowly overlapped with him。

“There are talented people coming out from generation to generation, the next generation is to be feared, the next generation is to be feared! "

The test given by Shimura has been forgotten by Yan Sagawa. After taking the first step, he naturally went to the second step. What he is doing now is the proof of Mersenne prime numbers, trying to pick off this bright diamond in number theory. .The

blackboard gradually filled up, but Sagawa Yan’s chalk stopped, and his thoughts were stuck.…

“Okay, that's it for now, I have complete confidence in your ability. Goro

Shimura saw his state and came to the rescue, "You have already exceeded the test I gave you, and you have reached the second or even third step. Maybe after you study in depth, I can really see you." The day the Mersenne primes were solved. "

At this time, it was already 2 o'clock in the morning. Goro Shimura yawned. After all, he was almost 70 years old and his energy was a little low. "You can rest at my place tonight. We will go directly to borrow a large machine tomorrow. computer。”

“It's really disturbing. "

None of the three mentioned the issue of going to school, as if it was not an issue worth discussing.

While Sagawa Yan went to wash up, Shimura Goro pulled Ishida to the side.。

“Ishida, you did a good job this time and cultivated a good seedling.。”

“Everywhere, it is Sagawa-san's own efforts. However, this is the first time I have seen a student like Sagawa for so many years of teaching. He is extremely talented and works very hard. He is simply a treasure given to our Yamato nation by Amaterasu. "

Teacher Ishida couldn't help but praise when he thought of getting along with Sagawa Yan.

Shimura Goro seemed to be recalling something in his eyes, and after a while he said, "The back view of him just writing on the blackboard reminded me of a person. In him, I seem to see senior Kunihiko Kodaira. shadow. "

Ishida was surprised. This evaluation is higher than his own. After all, Sakura Country will produce a treasure from time to time, a beauty that appears every few thousand years, but it is different to say that it looks like Kunihiko Kodaira. Who is Kunihiko Kodaira

? It can be said that he is the number one mathematician in Sakura Country. He is the only winner of the Fields Medal and the Wolf Prize in Mathematics in the country. He wrote high school mathematics textbooks that are still in use today.。

“I didn’t expect you to think so highly of him,” Ishida said blankly.。

“He deserves my evaluation," Goro Shimura said affirmatively。

…

A night of silence.

The next day,

led by Goro Shimura, the three of them came to the computer center of Toto University.

As the number one university in the country, the large computer school has。

“Just give them the data you want to calculate and come back in the afternoon to get the results."

After a few simple words, Shimura Goro left. As a professor at the School of Mathematics, he was still very busy.。

“Sagawa, this is a rare opportunity, so just walk around the school by yourself. Anyway, you will come to class in the second half of the year. Take it as a way to familiarize yourself with the school in advance. Teacher, I will go and catch up with old classmates. "

Ishida went to find his old classmate with a red face, but Sagawa Yan always felt that that old classmate was actually his old lover.。

“Speaking of which, as a nearly 30-year-old senior single, Mr. Ishida must have been waiting for that old lover. "

Sagawa Yan thought darkly.
