Chapter 1445: You Have a Problem
“Jin Ling University is here. Pa.s.sengers who get off the train at this station, please remember your belongings and get off the train in an orderly fas.h.i.+on…”
The sound of the announcement floated above Lu Zhou’s head, awakening him from the memory of the past.
At the same time, the real-time navigation system opened in his holographic gla.s.ses also had a pop-up window to remind him that he had arrived at the station.
Lu Zhou turned off the holographic panel floating in front of him. He stood up from his seat and got out of the train with the flow of people, embarking on the place where he once wielded 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.
Where…
Is this?
It was completely different from the Jin Ling University in his memory. The familiar tree trails were gone. There were gardening drones floating on the lawn. Silver and white buildings on both sides, even the shape of the buildings were completely changed.
Lu Zhou pushed the AR gla.s.ses up the bridge of his nose. He set up navigation to the mathematics department building, but the navigation cursor in front of him was divided into three different paths.
Three mathematics buildings?
After seeing the feedback from the navigation system, Lu Zhou was shocked.
When did the math department get so rich?
Lu Zhou was in shock for a while and didn’t know where to go. He was suddenly b.u.mped into from behind.
Although it was an unexpected collision, Lu Zhou himself was fine, but the person who b.u.mped into him almost fell to the ground.
“Sorry, sorry, I’m in a hurry!”
The boy who accidentally b.u.mped into him picked up the gla.s.ses from the ground and was about to go.
However, Lu Zhou wasn’t willing to miss this opportunity. He wanted to find someone to ask for directions, so he quickly grabbed the boy’s arm.
“Wait a second, kid, how do you get to the mathematics department?”
“Mathematics department?” The boy was stunned. He looked at Lu Zhou and asked, “Which major?”
Lu Zhou blurted out subconsciously, “Number Theory…”
The boy with square-framed gla.s.ses snapped back to reality. He held Lu Zhou’s hand with a tragic expression.
“Oh f*ck, I was thinking who would walk so slowly, I didn’t expect you to be one of us! If you keep walking around so slowly, you’ll miss the facial paralysis cla.s.s!”
Facial paralysis?
Lu Zhou was taken aback for a moment. Before he realized what was going on, the boy began to run.
“Wait, wait a minute.”
“Wait for what, hurry up!”
“… Isn’t there a more convenient means of transportation?”
“What do you want on campus, fly in a car? Cough cough… You’re pretty fit, you’re not even out of breath, I’m so f*cking tired… Cough! Stop talking to me.”
Lu Zhou: “…”
Aren’t you the one who has been talking?
We’ve only run for a couple of steps, how unfit are you?
When Lu Zhou came back to his senses, he had been taken to the teaching building by this stubborn guy. They stepped into a lecture hall with seats arranged in a U shape.
After Lu Zhou found a seat in the back row, he looked around the cla.s.sroom, then looked at the tired and breathless student next to him and asked casually with interest, “They don’t take names for a large lecture like this right?”
Are all students in this era so punctual?
“Take names? What is that…”
Lu Zhou immediately realized that he was being an “old ancient popsicle” again, so he quickly changed his words.
“What is your name?”
“Zhang Tao!”
“What about the one on stage?”
“Professor Sun Jingwen…” Zhang Tao’s eyes widened for a moment. He looked at Lu Zhou incredulously and said, “The f*ck, you don’t even know him?”
Lu Zhou smiled embarra.s.sedly.
Seeing how this young man was quite interesting, he joked, “Why do you think every time I attend an academic conference, I never ask someone for their business card?”
Zhang Tao glanced at him.
Every time…
How many conferences have you been to?
He spoke casually.
“Why…”
Lu Zhou sighed softly.
“Because I have face blindness.”
There were plenty of people he didn’t know, but everyone knew him.
However, this kid apparently took his words as a joke. After holding his stomach and laughing for a while, he sat up and spoke.
“Ahem… Bro, you’re so funny, I nearly couldn’t catch my breath. What’s your virtual community account? If you have time, we can go to the blue Calan Empire planet together, it’ll be fun.”
Lu Zhou smiled mysteriously and didn’t answer the question. Instead, he pointed in the direction of the podium and spoke.
“It’s starting, let’s listen carefully, talk about other things after cla.s.s.”
On stage.
A man with rimless gla.s.ses and a meticulous expression and who was a simple set of formal attire walked to the podium.
After his finger tapped twice on the multimedia device, four digital whiteboards appeared 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 very rich at all. Almost like his facial muscles had fallen into dormancy as if to conserve energy. Ever since he entered the cla.s.sroom, the expression on his face had not changed even a bit.
“Today’s content may be a bit super-dimensional. It involves the most difficult problem in mathematics, that is, whether all non-trivial zeros of Dirichlet’s L function are located on the straight line of the complex plane Re(s)=12.
“If you have studied your homework, you should not be unfamiliar with this problem. This proposition is a generalization problem raised by Academician Lu at the 2022 International Congress of Mathematicians in St. Petersburg. It is often referred to as the Generalized Riemann hypothesis, and it is also my research problem.
“My teaching philosophy has always been that mathematics is a discipline honed in practice. If you don’t think about it yourself, what I teach you will never truly become yours.
“Listen as much as possible if you can, record if you don’t understand, then go back and ponder slowly.”
He turned to face the first whiteboard and wrote a line of calculations on it.
This line of calculation caused Zhang Tao, who was sitting next to Lu Zhou, to frown in pain, but Lu Zhou was very familiar with this.
Isn’t this…
What I wrote on the blackboard at the St. Petersburg conference?
“Replace the infinite series in the Euler product formula with the complex exponent s, and then set Re(s)>1, and introduce the Dirichlet L function… Interesting.”
When Zhang Tao listened to the whispers from the mouth of the older guy sitting next to him, he was suddenly startled.
There’s someone who can understand this f*cking stuff?
He was just planning to complain about it on the anonymous school forum, that no one could understand this…
“You can understand what he wrote?”
Lu Zhou replied, “Sort of.”
Zhang Tao asked tentatively, “Group… Group Structure Method?”
“What nonsense are you talking about?” Lu Zhou glanced at him and said, “The part after the introduction of Dirichlet’s L function is of course the unified theory of algebraic geometry. Have you seen the Group Structure Method before?”
The problem is that I have never seen the unified theory of algebraic geometry either…
Aware of his ignorance, Zhang Tao closed his mouth with shame.
Lu Zhou sighed slightly and continued, “It’s fine… From what I remember, very few people can understand this theory to this degree, and the usage is a bit rigid. The old method is not always applicable, if only it was more flexible.”
As soon as Zhang Tao heard these words, he felt even more ashamed.
For f*ck sake, he’s just bragging as well! How come he’s so cool and clean about it, whereas I’m so nervous?
If only I were more confident.
This guy is a genius!
The whiteboard on the stage had been written all over. Professor Sun Jingwen, who was lost in thought, seemed to have forgotten that he was in a cla.s.sroom. His attention was fully focused on the problem in front of him.
However, he seemed to be in a little trouble as he stood there and frowned, as if pondering about something.
In fact, he was indeed in trouble, at least in Lu Zhou’s opinion.
If no one helped him, he wouldn’t be able to solve this problem even by tomorrow.
Lu Zhou sighed lightly. He was hesitating whether to help this guy when he suddenly noticed the red b.u.t.ton on the corner of the table.
With a hint of curiosity in his eyes, Lu Zhou touched Zhang Tao, who was sitting next to him, with his finger and pointed to the b.u.t.ton.
“What is this?”
“It’s to raise your hand, used in large cla.s.srooms.”
“I see…”
Lu Zhou reached out his hand and pressed it on the b.u.t.ton.
He thought that there would be red lights flas.h.i.+ng, or sound effects, but there was nothing.
However, Lu Zhou quickly noticed pairs of eyes staring at him, like he had been shouting in the cla.s.sroom.
Zhang Tao looked at Lu Zhou dumbfounded, and he quickly pulled Lu Zhou’s sleeves.
“The f*ck… what are you doing?!”
In the mathematics department of Jinling University, everyone knew that Mr. Facial Paralysis hated people interrupting his thoughts.
Especially when his research was at a critical stage…
Interrupting him at this moment to ask questions was no different than suicide.
Zhang Tao’s voice became weaker and weaker. A sharp line of sight had already shot up from the podium…
Professor Sun Jingwen looked at Lu Zhou blankly.
“You have a question?”
“No.” Lu Zhou stood up from his seat and shook his head slightly. He smiled and said, “But you have a problem.”
A loud noise spread in the cla.s.sroom.
All of the students were in disbelief. They looked at Lu Zhou, then at Sun Jingwen, who was standing in front of the podium.
Does this guy not want to live anymore?
Many people even showed gloating expressions on their faces, waiting for Professor Sun’s next reaction.
However, an unbelievable scene happened.
Professor Sun, who was on the stage, was not as angry as most people expected. Instead, he frowned and asked, “Where is the problem?”
Lu Zhou: “Inference 4 in line 24, there is nothing wrong with the idea of introducing differential manifolds here, but I think L manifolds… When Academician Lu was designing it, he probably never thought that it would be used to solve the Dirichlet L function problem.”
“Of course I know that.” Sun Jingwen stared at Lu Zhou’s face, trying to take a look at it more clearly, but he still did not recognize him. Sun Jingwen said, “L Manifold was his solution to the NS equation problem, it was not used to solve the Dirichlet L function problem, but it was one of the key elements in solving Riemann’s hypothesis. It is also undeniable that it serves as the core tool of the unified theory of algebraic geometry.”
“Your research on the history of mathematics is good, but mathematics research is not archaeology after all.” Lu Zhou said with a gentle smile, “Can I borrow a whiteboard?”
Professor Sun Jingwen seemed to be stunned. He didn’t expect this student to do this.
But he didn’t say much. He just nodded his head blankly and made a gesture casually.
“Please, go ahead.”
