Chapter 43: Invitation
Holding the answer sheet, Zhang Weiping's eyes looking at Xu Chuan were a little complicated, with surprise, doubt, and incredible......
Can a high school student really have such strong math ability?
If he gets a full score in the CMO national finals of the digital competition, he can still be classified as a genius, and it can also confirm that his basic mathematical skills are solid.
The answers and solutions on this piece of paper reflect the strength of his mathematical ability, and confirm that this is a complete demon.
Being stared at by Zhang Weiping with strange eyes, Xu Chuan was a little uncomfortable, coughed lightly, broke the embarrassment and asked:
"Is there any answer to the question? Teacher? ”
"No, no questions, excellent answers, and the answers are correct." Zhang Weiping shook his head and said.
"And why is this answer so strange?"
Xu Chuan asked with some curiosity: "These three numbers obviously do not conform to the law of solving the Dirichlet function. ”
"That's what I'm going to talk about next, but you'll have to wait a little bit."
With that, Zhang Weiping got up and left the office.
Xu Chuan frowned, a little unclear, but he vaguely felt something in his heart, so he waited quietly in the office.
After waiting for nearly ten minutes, Zhang Weiping came back.
After locking the office door to prevent someone from accidentally breaking in, Zhang Weiping pointed to the answer on the manuscript paper and asked Xu Chuan:
"Can you guess what these three numbers mean?"
Xu Chuan shook his head, this headless and brainless, who could have guessed?
He's not a fortune teller.
"These three sets of numbers are actually latitude and longitude and time."
Hearing this, Xu Chuan's pupils suddenly contracted, and he probably understood. However, he didn't speak, and waited for Zhang Weiping to continue to explain with a blank face.
Zhang Weiping paused, organized the language, and continued:
"Forget it, I'll just say it, after all, you're almost an adult, and your math ability is a little stronger than I imagined, and it's okay to tell you some things."
"You can also see that this question is a mathematical law problem, but it is actually an overseas intelligence intercepted by our country's Information Security Department."
Zhang Wei 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 p.m. on the 14th, there were activities and transactions of foreign forces in the place of 116.72 east longitude and 39.56 north latitude."
"Of course, that was many days ago."
"In fact, many times, the exchanges between countries are far less friendly than what you see on TV and on the Internet."
"For the sake of interests, in order to crush and control their opponents, many countries will do whatever it takes."
"Stealing, spying, buying, or illegally providing state secret information of all kinds is not uncommon, and these activities can bring huge amounts of damage or economic losses."
"Just like now, we have recently intercepted a lot of intelligence information from abroad, but these intelligence information uses a special encryption method."
"The math problem you just made is one of the ways to encrypt this information."
"But we're in trouble right now, because we intercept a huge amount of encrypted messages every day, and it takes a lot of manpower to decipher them, and as of now, we can't keep up with them."
"You should know that when it comes to information, the timeliness and accuracy of information is the most important thing."
"It's like calling the police to catch a thief, it takes a while for the police to get to the victim's house, and that time, it's enough for the thief to steal something."
"Even if the thief can be caught afterwards, the stolen property may be consumed, sold and never recovered."
"It's the same with information decipherment, when our side deciphers the encrypted information and arranges personnel to arrest the other party, the other party's activities have been completed."
"So we're always one step slower, and one step slower will cause huge losses."
"Now we are making a mathematical model for this kind of encrypted messages, trying to use the mathematical model to decipher those encrypted messages, but we are encountering many difficulties."
"And this new math method that you're using to do the problem is exactly what we need."
"I need your help, and the motherland needs your help."
Zhang Weiping briefly described the cause of the incident, these things were originally confidential, and it was impossible to say it to a high school student.
However, Xu Chuan is an exception, and the method he used to solve the problem tonight was very easy to understand the work of the Dirichlet function law problem.
This is a great help for mathematical modelling work, and although it is only a small part, its importance is undeniable.
So after being authorized and investigating Xu Chuan's family background, he revealed part of the information.
The Department of Information Security needs Xu Chuan's help, at least for him to explain clearly the key to solving the Dirichlet function by the simplified method.
Although he had already seen how to solve the problem, it was not enough.
A new mathematical idea, it often takes a while for everyone but the inventor himself to figure out what it is.
Just looking at the answers to the problem that applied this method twice is not enough to figure out the core.
And the best way to apply this new method in the early days was to find the inventor himself.
As for doubting whether this method was really researched 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 encryption problem in fifteen minutes, his doubts were dispelled.
Zhang Weiping really didn't expect that this national rally would give him such a big surprise.
He previously proposed to put the mathematical problems on the encrypted message into the Olympiad National Set and the college students' modeling competitions, the purpose of which was just to cultivate some mathematical talents in this area for the country, and to collect some information and data to assist the modeling work.
After all, the students who can make it to the finals of the National Mathematics Competition and the College Student Modeling Finals are the geniuses of geniuses.
Although these young people have the mathematical ability and the mathematical knowledge stored in their minds are far less than that of mathematics professors, don't underestimate the thinking of a genius.
Maybe some geniuses gave inspiration to someone?
Mathematics has always been the world of young people.
At the age of 24, Pete Schulz became the youngest 3C professor in Germania, and Tao Zhexuan became a tenured professor in the Department of Mathematics at UCLA at the age of 24.
If a mathematician does not contribute enough before the age of forty, it is unlikely that he will have made any mathematical contributions in his lifetime.
Many times, genius thinking and logic are unimaginable to ordinary people.
It's just that Zhang Weiping never thought that there would be such a genius in the Olympiad National Collection, a genius with the ability to teach mathematics comparable to mathematics, and also mastered a new mathematical method, which is of great help to information security modeling work.
