Great Country Academician

Holding the answer sheet, Zhang Weiping looked at Xu Chuan with mixed eyes, full of surprise, suspicion, and disbelief.

Can a high school student really have such a strong mathematical ability?

If he got a full score in the CMO national competition, he can still be classified as a genius, and it can also prove that his basic skills in mathematics are solid.

The answers and problem-solving ideas on this piece of manuscript paper reflect the strength of his mathematical ability and prove that this is a full-fledged monster.

Being stared at by Zhang Weiping with strange eyes, Xu Chuan felt a little uncomfortable, coughed lightly, and broke the embarrassment and asked:

"Is there any question for the answer? Teacher?"

"No, there is no question. It is an excellent answer, and the answer is correct." Zhang Weiping shook his head and said.

"Then why is this answer so strange?"

Xu Chuan asked curiously: "These three numbers obviously do not conform to the law of solving the Dirichlet function."

"That's what I'm going to say next, but you have to wait for me a moment."

With that said, Zhang Weiping got up and left the office.

Xu Chuan frowned, not knowing why, but he vaguely felt something in his heart, and waited quietly in the office.

After waiting for nearly ten minutes, Zhang Weiping came back.

After locking the door of the office to prevent anyone from accidentally breaking in, Zhang Weiping pointed to the answer on the manuscript paper and asked Xu Chuan:

"Can you guess what these three sets of numbers mean?"

Xu Chuan shook his head, who would have guessed that it was headless?

He is not a fortune teller.

"These three sets of numbers are actually latitude and longitude and time."

Hearing this, Xu Chuan's pupils suddenly shrank, and he probably understood. But he didn't speak, and waited for Zhang Weiping to continue to explain with a blank face.

Zhang Weiping paused, organized his language and continued:

"Forget it, let me just say it directly. After all, you are almost an adult, and your math ability is beyond my imagination. It's okay to tell you something."

"This question, you can also see that it is a mathematical law question, but it is actually an intelligence letter."

Zhang Weiping said slowly.

"These three sets of numbers represent 116.72 east longitude, 39.56 north latitude, and 12:25 noon on the 14th!"

"It means that at 12:25 noon on the 14th, there were activities and transactions at 116.72 east longitude and 39.56 north latitude."

"Of course, this was many days ago."

"Actually, in many cases, the reality is far less friendly than what you see on TV and the Internet."

"For the sake of profit, in order to defeat and control the opponent, many people will do whatever they can."

"Just like now, we have intercepted a lot of intelligence information in the near future, but these intelligence information use a special encryption method."

"The math problem you just made is one of the ways to encrypt these information."

"However, we are in trouble now, because a large number of encrypted messages are intercepted every day, and deciphering these encrypted messages requires a lot of manpower. As of now, our manpower can no longer keep up."

"You should know that when it comes to information, the timeliness and accuracy of the information is the most important thing."

"It's like calling the police to catch a thief. It takes a while for the police to arrive at the victim's house, and that's enough time for the thief to steal something."

"Even if the thief can be caught afterwards, the stolen property may be consumed, sold and never retrieved."

"The same is true for information deciphering. When we decipher the encrypted information and arrange personnel to arrest the other party, the other party's activities will have been completed."

"So we are always one step slower, and one step slower will cause huge losses."

"Now we are making a mathematical model for this encrypted message, trying to use the mathematical model to decipher those encrypted messages, but we have encountered many difficulties."

"And this new mathematical method that you used to solve the problem is exactly what we need."

"I need your help, and the motherland also needs your help."

Zhang Weiping gave a brief and rough description of the origin of the matter. These things were originally confidential, and it was impossible to tell a high school student.

However, Xu Chuan is an exception. The method he used to solve the problem tonight is extremely convenient to understand the work of the Dirichlet function law problem.

This is of great help to mathematical modeling work. Although it is only a small part, its importance is beyond doubt.

So after obtaining authorization and investigating Xu Chuan's family background, he disclosed some information.

The Information Security Department needs Xu Chuan's help, at least the key to solving the Dirichlet function by the simplified method he explained clearly.

Although he has seen the solution to the problem, it is not enough.

A new mathematical idea, in addition to the inventor himself, it often takes a while for others to figure out what is going on.

Just looking at the answers to the problems using this method twice is not enough to figure out the core.

And if you want to apply this new method freely in the early stage, the best way is to find the inventor himself.

As for doubting whether this method was really developed by the high school student in front of him, he still had it at first, but after Xu Chuan used this method to solve the encrypted problem in fifteen minutes, the doubt was dispelled.

Zhang Weiping really did not expect that this National Assembly would give him such a big surprise.

He previously proposed to put the math problems on encrypted messages into the Olympiad National Contest and college student modeling competitions. The purpose was just to cultivate some mathematical talents in this area for the country, and to collect some information and data to assist in the modeling work. .

After all, the students who can reach the finals of the National Competition and College Modeling are all geniuses among geniuses.

Although these young people's mathematical ability and mathematical knowledge in their minds are far inferior to those of mathematics professors, don't underestimate the thinking of a genius.

Maybe which geniuses gave a certain inspiration?

Mathematics has always been the domain of young people.

Pete Schulz became the youngest 3C professor in Germany at the age of 24, and Terence Tao became a tenured professor of UCLA's Department of Mathematics at the age of 24.

If a mathematician does not make enough contributions before the age of forty, it is basically unlikely that he will make any mathematical contributions in his life.

In many cases, the thinking and logic of geniuses are beyond the imagination of ordinary people.

It's just that Zhang Weiping never thought that such a genius would appear in the National Mathematical Olympiad, a genius who has the ability to teach mathematics, and also masters a brand-new mathematical method, which is of great help to the information security modeling work.
