"We have arrived at the Jin Ling University station. Passengers who get off at this station, please take your belongings with you and get off in order …"
The reminder floating above his head awakened Lu Zhou from his memories of the past.
At the same time, the real-time navigation system opened by the holographic glasses was also printed with the arrival reminder pop-up window.
After turning off the holographic panel floating in front of him, Lu Zhou stood up from his seat and followed the flow of people out of the car. He set foot on the place where he once spent his youth with excitement and anxiety.
However, when he stepped out of the station and the sun shone on his face, Lu Zhou was stunned.
This place …
Where is this place?
It was completely different from the Jin Ling University in his memory. The familiar sycamore path was gone, and gardening drones were floating on the lawn. The silver-white buildings on both sides of the road had no function. Even the shape of the teaching building was completely different.
Lu Zhou pushed the AR glasses on the bridge of his nose and set the label of the mathematics department laboratory building. However, the navigation cursor in front of him was divided into three different paths.
Three laboratory buildings?!
When he saw the feedback from the navigation system, Lu Zhou was shocked.
When did the mathematics department become so rich?
Just when Lu Zhou was in a dilemma and didn't know where to go, he was suddenly hit on the back.
Although it was an unexpected hit, Lu Zhou was fine, but the person who hit him almost fell to the ground.
"Sorry, sorry, I'm in a hurry!"
Picking up the glasses from the ground, the boy who accidentally bumped into his back hurriedly apologized and was about to leave.
However, how could Lu Zhou miss this opportunity? He was about to ask someone for directions, so he quickly grabbed the boy's arm.
"Wait a minute, student, how do I get to the mathematics department?"
"Mathematics department?" The boy was stunned. He looked at Lu Zhou and asked, "Which major?"
Lu Zhou blurted out.
"Number theory …"
When the boy with the square-rimmed glasses heard that it was number theory, he immediately snapped back to reality and held onto Lu Zhou's hand.
"F * ck, I was wondering which courtyard you were from. Why are you so slow? Are you from our courtyard? How dare you dawdle in a class with facial paralysis? Don't you want your credits anymore?! "
Facial paralysis?
Lu Zhou was stunned for a second. He didn't know what was going on, but he was already being pulled along.
"Wait, wait a minute."
"What are you waiting for? Let's go!"
"What I mean is … isn't there a more convenient means of transportation?"
"What else do you want to do in school? Fly there by car? Cough cough … Your stamina is pretty good. You don't even pant when you run. I'm f * cking … f * cking … f * ck! Don't talk to me. "
Lu Zhou: "…"
Aren't you the one talking the whole time?
But with your physique, you're panting like this after just a few steps. That's too bad.
When Lu Zhou came back to his senses, he had already been taken to the teaching building by this talkative boy. He guessed the time of the class bell and stepped into a lecture hall with a U-shaped seating arrangement.
Lu Zhou found a seat in the back row and looked around the classroom. He then looked at the exhausted student next to him and asked casually, "What's wrong?"
"This kind of big class, they usually don't call attendance, right?"
Are students of this era so diligent?
"Call attendance? What's that … "
Looking at the stunned expression on the boy's face, Lu Zhou immediately guessed that he was probably suffering from "frozen human social difference syndrome", so he quickly changed his words.
"What's your name?"
"Zhang Tao!"
"Who's on stage?"
"Professor Sun Jingwen …" Zhang Tao's eyes widened in an instant. He looked at Lu Zhou in disbelief and said, "F * ck me, you don't even … know him?"
Lu Zhou smiled embarrassedly when he heard this stupid question.
He saw that this young man was quite interesting, so he joked.
"Guess why I never ask for business cards at an academic conference?"
Zhang Tao glanced at him.
Every time …
At your age, can't you at most get one or two?
However, he didn't expose her and just gave a perfunctory reply.
"Why …"
Lu Zhou didn't care about the perfunctory tone and sighed softly.
"Because I'm face-blind."
What should I say?
There were a lot of people he didn't know, but everyone knew him.
However, this kid obviously took his words as a joke. He held his stomach and twitched exaggeratedly for a while before he awkwardly straightened his body.
"Ahem … Dude, you're so funny. I almost couldn't breathe. Why don't we exchange virtual community accounts? When we have time, let's go to the Calan Empire. It won't be boring to play with you. "
Lu Zhou smiled mysteriously. He didn't answer the question directly. He just pointed in the direction of the podium.
"It's starting. Let's listen carefully. We'll talk about other things after class."
On stage.
A man with rimless glasses, dressed in a plain suit, and a meticulous expression walked to the podium.
His index finger tapped on the multimedia panel twice, and circles of digital cracks spread out in all directions, forming four whiteboards on the wall.
Lu Zhou finally knew why this guy was called facial paralysis by the students. It was because his expression was really not rich. His facial muscles seemed to have fallen into a dormant state to save energy. Since he walked into the classroom, the expression on his face had not changed at all.
"Today's content may be a bit super-dimensional. It involves the most difficult problem in mathematics at present, that is, whether all the non-trivial zeros of the Dirichlet L function are located on the line of the complex plane Re (s) = 12.
"If you have prepared your homework, you should be familiar with this problem. This proposition is a generalization problem proposed by Academician Lu at the 2022 International Congress of Mathematicians in St. Petersburg. It is often called the generalized Riemann conjecture, and it is also the problem I am studying.
"My teaching philosophy has always been like this. Mathematics is a discipline that is honed in practice. If you don't think about it, what I teach you will never become yours.
"Try to listen as much as you can. If you don't understand, record it. Go back and think about it slowly."
While the students were sighing, he turned to the first whiteboard and wrote a line of calculations on it.
This line of calculations made Zhang Tao, who was sitting next to Lu Zhou, frown in pain, but Lu Zhou was very familiar with it.
This thing …
I seem to have written on the blackboard at the Congress of Mathematicians in St. Petersburg?
"Replace the infinite series in Euler's product formula with the complex exponent s, then set Re (s) > 1, and introduce the Dirichlet L function … Interesting."
Listening to the big brother sitting next to him whisper to himself, Zhang Tao was taken aback.
How the f * ck can someone understand this?
He was just about to complain on the school's anonymous community, but the poker face wrote something that only he could understand …
"You can understand what he's writing?"
Lu Zhou replied casually.
"Sort of."
Zhang Tao asked tentatively.
"Group … Group Structure Method?"
"What nonsense are you talking about?" Lu Zhou glanced at him faintly. "The part after the introduction of the Dirichlet L function is, of course, the unified theory of algebraic geometry. Have you ever seen such a Group Structure Method?"
The problem is that I haven't seen the unified theory of algebraic geometry either …
Realizing his ignorance, Zhang Tao closed his mouth in shame.
Lu Zhou sighed softly and continued to speak.
"… It's not too bad. In my impression, there are very few people who can understand this theory to such a degree. It's just that the method used is a little rigid. The old method doesn't work all the time. It'll be fine if you make some changes."
As soon as he heard these words, Zhang Tao's face suddenly became even more ashamed.
Jesus Christ, I'm also bragging, but why is this guy so fresh and natural? His face is not red, his heart is not beating, and his hands are not shaking?
The point is that I almost believed it.
What a f * cking genius!
Professor Sun Jingwen, who was lost in thought, had written all over the whiteboard. He seemed to have forgotten that he was in a classroom, and his attention was completely focused on the problem in front of him.
However, he seemed to have encountered a little trouble. He stood there with his brows furrowed as if he was struggling with something.
In fact, he was indeed in trouble, at least in the eyes of Lu Zhou.
If no one reminded him, he was afraid that even if he wanted to go tomorrow, he would not be able to think of a reason.
Lu Zhou sighed softly. Just as he was hesitating about whether to help this guy, his eyes suddenly fell on the red button on the corner of the table.
With a trace of curiosity in his eyes, Lu Zhou touched Zhang Tao, who was sitting next to him, with his index finger and pointed to the button.
"What is this?"
"It's used to replace raising one's hand. Usually this kind of big classroom has it."
"I see."
Lu Zhou nodded thoughtfully. He then reached out and pressed the button.
He originally thought there would be a red light flashing or a sound effect, but there was nothing.
However, Lu Zhou soon saw pairs of eyes looking at him. It was more eye-catching than shouting with a loudspeaker.
Zhang Tao, who was sitting next to Lu Zhou, was dumbfounded. He quickly pulled Lu Zhou's sleeve.
"F * ck … Do you want to die?!"
In the mathematics department of Jin Ling University, everyone knew that the guy with facial paralysis hated people interrupting his thinking.
Especially when his research was at a critical stage …
Interrupting him at this time to ask questions was no different from asking for death.
Zhang Tao's voice became weaker and weaker. Because while he was speaking, a sharp gaze had already shot over from the podium …
Professor Sun Jingwen pushed his rimless glasses and looked at Lu Zhou blankly.
"You have a problem?"
"No." Standing up from his seat, Lu Zhou shook his head gently, smiled, and said, "You have a problem."
As soon as he finished speaking, the classroom burst into an uproar.
The faces of the students showed expressions of disbelief. They looked at Lu Zhou, then looked at Sun Jingwen, who was standing in front of the podium.
What was the difference between this blunt way of speaking and courting death?
Many people even showed expressions of schadenfreude on their faces, waiting for Professor Sun's next reaction.
However, an unimaginable scene happened.
Professor Sun, who was standing on the stage, did not get angry as most people expected. Instead, he frowned.
"… What's the problem?"
Lu Zhou: "Inference 4 of line 24, there is nothing wrong with your idea of introducing differential manifolds here, but I think the L Manifold … When Academician Lu designed it, he probably didn't think that it would be used to solve the Dirichlet L function problem."
"Of course I know." Sun Jingwen pushed his glasses and stared at Lu Zhou's face, trying to see it more clearly, but he still didn't recognize where this strange face came from. He said, "The L Manifold is the key he prepared to solve the Navier – Stokes equation problem. It is not used to solve the Dirichlet L function problem, but as one of the key elements to solve the Riemann conjecture, it is undeniable that it is the core tool of the unified theory of algebraic geometry."
"Your research in the history of mathematics is good, but mathematics research is not archaeology after all." Lu Zhou smiled and said in a gentle tone, "Can I borrow a whiteboard to talk?"
Professor Sun Jingwen seemed to be stunned. He didn't expect this student to be serious.
However, he didn't say anything. He just nodded blankly and made an inviting gesture.
"Please."
