"Mr. Xu, Lou Song contacted me via WeChat, asking if you have time recently, and would like to discuss some issues with you."

Hearing that Lou Song wanted to find him, Xu You naturally had no reason to refuse.

"Understood, I will reply to him personally in a while."

"Okay, Teacher Xu."

Speaking of Lou Song, Xu You hasn't seen him for a while.

This was not what Xu You wanted, but he was busy with matters related to the moon landing project during this period, and he really couldn't get away.

Because of his professional relationship, Lou Song did not directly participate in the moon landing project, but occasionally chatted with Xu You about some academic issues.

This time Lou Song took the initiative to contact him, there must be some important new discovery that he wants to share with him.

After finishing the work at hand, Xu You got in touch with Lou Song.

Listening to Lou Song's tone on the phone, it seems that this matter is very important, so Xu You and Lou Song agreed to meet in the afternoon.

"Normally, Lou Song wouldn't be in such a hurry. Otherwise, Lou Song wouldn't contact me through Cui Ying."

Thinking of this, Xu You felt more and more that Lou Song's discovery this time should not be simple.

When the appointed time came, Lou Song appeared in front of Xu You's office on time.

"Teacher Lou, please come in."

"Okay, please trouble Teacher Cui."

Lou Song walked into Xu You's office, and when they saw each other, they both looked at each other and smiled.

It's been nearly a decade since the two first met at a competition.

During this period, the two have achieved countless achievements in their respective fields, and their identities have also undergone great changes.

What has not changed is their awe of knowledge and their hearts of exploration.

"Tell you good news, Riemann guesses that I have completed half of the proof."

Hearing Lou Song's words, Xu You was also very excited.

"No wonder you are in such a hurry this time. Can you show me the idea of ​​the proof?"

"certainly."

Since Lou Song came to find Xu You in person, naturally he would not shy away from Xu You.

Lou Song turned on his computer and explained his thoughts to Xu You.

"In fact, the key to proving the Riemann Hypothesis does not necessarily lie in the derivation from the Riemann function, but also from the domain of definition of Re(s). Here, I use two theorems, which are negative real numbers The square root theorem, and the imaginary number generation theorem.”

"Theorem of imaginary number generation?" Xu You asked in surprise.

As we all know, when all negative real numbers are square rooted, an imaginary number will be produced.

For example, the imaginary unit i is the result obtained by calculating the arithmetic square root of -1.

"Yes. We can obtain the following series of formulas through the proof process of negative real number square root theorem and imaginary number generation theorem."

Lou Song quickly explained his thinking, omitting a lot of processes in the middle, even a professor in the Department of Mathematics may not be able to follow Lou Song's thinking.

However, this speed is just right for Xu You.

"So that's the case, this is really a wonderful way of thinking."

After listening to Lou Song explaining his whole train of thought, Xu You couldn't help but nodded vigorously.

Lou Song's thinking is very special, it can be said that it provides a new way of thinking for proving the Riemann Hypothesis.

Even if the proof of Riemann's conjecture has not been completely solved, at least half of the work has been completed.

"Lou Song, can you tell me how you came up with this method?"

Xu You has already understood Lou Song's train of thought, but he still hasn't figured out how Lou Song got such an inspiration.

This feeling is like after reading the analysis of the topic, I understand that the topic can do this, but I don’t know why I can find this direction.

"Actually, it can't be said that it's entirely my credit. Fulong's fan quantum machine gave me a lot of help."

"What? You've figured out how to get a quantum computer to solve a complex math problem?"

"I can't say that yet, but at least I have begun to learn how to use quantum computers as an auxiliary tool for solving mathematical problems."

Next, Lou Song described in detail how he used quantum computers to help him solve various complex mathematical problems.

Listening to Lou Song's idea of ​​using a quantum computer, Xu You nodded and sighed again and again.

"It turns out that you hope that quantum computers can learn mathematics like humans, and become a 'mathematician' with a certain foundation first. In this case, it will be much easier to solve mathematical problems."

"That's right, this is actually roughly the same as the idea of ​​artificial intelligence learning Go. It's just that mathematics is different from Go, and there is no clear winner or loser. There are still more difficulties for artificial intelligence to learn mathematics. "

What Lou Song can do now is not to completely let the quantum computer solve all the problems like the previous Suanjing artificial intelligence.

But just let artificial intelligence solve some small problems, and the big direction still needs to be controlled by humans.

Even so, this is a very big breakthrough in the history of mathematics.

"Now my thoughts on artificial intelligence have completely changed. I don't think it is impossible for artificial intelligence to surpass humans in mathematics, and I don't think there is any regret in it. Since the invention of computers, humans have been relying on They went to solve math problems." Lou Song said.

"Yes, in fact, human beings have been making various tools to help themselves solve complex problems. As early as two thousand years ago, our ancestors invented the abacus, which can be regarded as the 'calculator' used by human beings in the early days Yes. Since they are all tools invented by ourselves, it is only natural for us to use them."

Lou Song nodded again and again after listening, expressing that this is indeed the truth.

After talking about what Riemann conjectured, Lou Song did not leave immediately, but continued:

"This is the first thing I came to you today. Next, there is one more important thing."

Xu You was taken aback when he heard the words, and couldn't help frowning slightly.

Xu You also felt that Lou Song's ability to discover the proof direction of Riemann's conjecture was indeed very important, but it was not so important that he needed to see Xu You immediately.

Even if I tell Xu You about this a few days later, it won't have any effect.

Sure enough, Lou Song has some more important things to do this time.

"What is it, tell me quickly."

"Remember when the Sam Fed suddenly announced a rate hike a while ago?"

Xu You didn't expect that what Lou Song wanted to talk to him about was actually related to Sam's interest rate hike.
