At noon, Zhang Weiping called and asked him to prepare for the afternoon small class.
Xu Chuan packed up the information, sorted out his thoughts, and came to the mathematics room in advance, and found that Zhang Weiping was already waiting for him here.
"Don't be nervous, don't be afraid, just treat it as your normal communication with your classmates and teammates."
Zhang Weiping smiled and comforted Xu Chuan, not to feel too much pressure.
In fact, this can be regarded as a platform he provided Xu Chuan to let the mathematics professors in the mathematics room get familiar with him, so that he can find some mathematics professors for advice when he encounters problems in his studies in the future.
As for the questions and explanations, the core manuscript provided by Xu Chuan has been very clear.
After all, this is not something very cutting-edge or complicated. Most mathematics professors can successfully understand it after getting the core manuscript.
Xu Chuan nodded and responded. If this was applied to an ordinary student, even a doctoral student would be extremely nervous.
After all, the mathematicians involved in deciphering the encrypted messages are all top mathematics professors in the country. It is not easy for a senior high school student to explain his knowledge to these professors who can be his teachers.
But to him, it was nothing.
The physics conferences and mathematics conferences he held before his rebirth brought together some of the top leaders in the world. In comparison, the level of today's conferences was really average.
However, he attaches great importance to it because this is a good opportunity to solve the information war.
...
At 1:30 in the afternoon, there was no curtain or conference room in the mathematics room. A dozen mathematics professors gathered around a makeshift table and chatted, just like the way housewives in rural areas gather to gossip and chat on a daily basis.
"Ahem, okay, everyone is here, let's start."
Zhang Weiping cleared his throat, coughed and then continued: "We are all old acquaintances, so I won't introduce you to them, but I'd better be careful later and don't scare our classmate Xu Chuan. After all, he is only a senior in high school. .”
Hearing this, the mathematics professors sitting together became lively.
"Old Zhang, look at what you said. It's too late to protect me, so why are you so scared?"
"Senior year of high school. At that time, I could only play cards in the dormitory."
"Student Xu Chuan, are you interested in studying at Shuimu University? You can ask for whatever conditions you want. Our Shuimu University is the number one university in the country."
Professor Wang Yuan from Shuimu University looked at Xu Chuan with a smile and invited.
"Oh, you old guy, you Shuimu are not as good as our P University in terms of mathematics. If you want to come, you must come to our P University. Xu Chuan, come to P University, I will personally take you!"
P Academician Zhou Jianlin of the University of Science and Technology raised his eyebrows and immediately retorted.
"Okay, what's there to argue about? Today's theme is not about robbing people! Don't listen to them, Xu Chuan, the mathematics department of Dongshan College is also very strong."
Professor Wei Anran from Dongshan College approved the top two and then joined the job robbing industry.
"Ahem, you guys are a bunch of old guys, please stop scaring people, and you'll be more excited."
Zhang Weiping glanced at the mathematics professors sitting around and rolled his eyes. He knew that this was the result.
However, after being interrupted like this, the atmosphere in the math room became a lot more lively.
After adjusting the atmosphere in the mathematics room, Zhang Weiping looked at Xu Chuan and said:
"Okay, let's start here now, Xu Chuan, don't be nervous, just treat it as normal. After all, you just saw the character of these old people."
"In this way, you first briefly describe the core idea of the simplified method you developed to solve the Dirichlet function, and then if others have questions, ask them. If you have an answer, just reply. It doesn't matter if you can't answer it. Don't worry about it. .”
Xu Chuan nodded, sorted out his thoughts, and explained the process of getting inspiration from "Progress in Physics" and then studying the damped free vibration equation and Dirichlet function.
He didn't focus on the core proof process. This thing was in the manuscript he listed two days ago. Everyone must be familiar with it by heart.
"...This is the entire process of solving the Dirichlet function using the simplified method."
After confirming that nothing was missing, Xu Chuan finished his presentation and waited for the big guys sitting around to ask questions.
"I didn't expect that classmate Xu Chuan's achievements in physics would be so high."
"He is an all-rounder in mathematics and physics. He is more suitable for our P University."
"..."
Seeing this group of people coming again, Zhang Weiping interrupted directly: "Okay, if you have any questions, ask them quickly. Don't waste time. After solving this problem, he still has to attend the national training."
After being corrected again by Zhang Weiping, everyone changed the topic to mathematical problems.
However, for this group of big guys sitting here, understanding the core of the simplified method to solve the Dirichlet function is not a problem. Only the mathematical experts involved in modeling raised two questions.
"Student Xu Chuan, I would like to ask, according to your core, if you use the simplification method to solve the Dirichlet function modeling, from converting the Dirichlet function to integrating, and then to solving, there are a total of thirteen differences in these two steps. The steps and solutions, right?”
Xu Chuan nodded. These were clearly written in the previous core document.
"Can we optimize it further? What I mean is whether the solutions can be arranged in sequence according to the corresponding solution range."
The mathematical expert in modeling asked: "Because for a mathematical model, if repeated operations and multiple selections are required, this will increase a lot of computing power."
"So prioritizing core solutions with a wide range of adaptability in the first group can reduce the demand for computing power in digital analog."
Xu Chuan nodded and said, "That's no problem. I can sort it out when I get back."
"Then I'll trouble you."
.......
After a brief meeting to deal with some problems in establishing digital models, Xu Chuan grabbed Zhang Weiping.
"Teacher Zhang, wait a moment."
As he spoke, he took out a stack of manuscript paper from the bag he had brought with him and handed it over.
"These are some of the answers I came up with when I was studying math problems these past two days. I can't figure out some of the problems. Can you help me?"
He burned all the original detailed manuscript papers, which he had newly written last night.
It is a preliminary compilation of the laws behind these encryption cores. It only provides two or three ideas and some problem-solving data that are relatively consistent with his current knowledge.
In order to disguise it, he also listed some unfinished data.
But this should be enough to inspire the mathematicians in the Information Security Department.
"okay."
Zhang Weiping took the manuscript paper, flipped through it, and prepared to give some advice to this mathematical genius.
"It's normal that you can't solve this problem, because this is the subject direction for doctoral graduates. This function needs to use Riemann's lemma to integrate both sides at the same time, and then turn it to L'Hôpital's law..."
"Huh? Have you split those encryption functions? It's interesting. Separate the transcoding system from the math problems, and then do the questions..."
"This idea..."
As the manuscript paper came into his eyes, Zhang Weiping became more and more surprised as he browsed the information. From the beginning, he could answer the questions left by Xu Chuan and provide guidance. Gradually, he fell into deep thought, and his brows furrowed unconsciously. got up.
A way to find the mathematical laws behind these encrypted messages gleamed in his mind.
Looking at Zhang Weiping who was deep in thought, Xu Chuan smiled at the corners of his eyes.
He knew that on his manuscript paper, Zhang Weiping had already found the path leading to the answer.
.......
