I am devoted to scientific research, but you want to trick me into having a love relationship?

Chapter 715 This isn't difficult, you can deduce it yourselves and have some fun.

The seminar room.

Everyone's attention turned to Zhang Zhigao because of Xu Qingzhou's problem.

Xu Qingzhou smiled faintly. It would be impolite not to retaliate; he wasn't the type to sit idly by and wait for his fate.

At the table, Zhang Zhigao stared at the complex and intricate formulas on the whiteboard, falling silent, trying to find loopholes in the calculations, but he couldn't find the calculation bug in the Fields Medal winner's work.
He is a physics expert with absolute confidence in the field of nuclear fusion, but he is not so arrogant as to think he can outdo Xu Qingzhou in the field of mathematics.

Rigorous, extremely rigorous.

Seeing Xu Qingzhou squinting at him, he cursed inwardly again, "You're already like this, how can I question you?"

Don't you think it's a bit much for someone like you who studies mathematics to ask me to discuss this?

Zhang Zhigao's face was rather unpleasant, and he felt extremely aggrieved. Suppressing the feeling of being fed, he forced himself to say, "Professor Xu's calculations are truly brilliant."

"As long as we can answer Academician Zhang's questions, that's fine."

Xu Qingzhou smiled and said nothing more, returning to his seat.

Across from him, seeing Zhang Zhigao speechless, Li Yi felt incredibly satisfied. "Old Deng, weren't you so arrogant just now?"

Ren Nan also held his teacup and took a sip of tea in a good mood.

Everyone's expressions were somewhat subtle, and no one spoke; the atmosphere in the room froze for a moment.

Li Gang stepped in with a smile to smooth things over, saying, "Our approach of using 'thematic seminars and group discussions' is essentially about deepening the understanding of issues through questioning. Now it seems that our meeting was quite successful."

"Yes, science progresses through communication."

Xiao Chenghan nodded with a smile as well.

"Alright, let's move on to the next topic."

In the last two days, apart from group discussions and small seminars, there was mainly collaborative work to be done, which had little to do with Xu Qingzhou and his team.

They were just there to make up the numbers. The institute's projects are currently saturated, and apart from small collaborations like nanoporous tungsten membranes, they don't have much energy left to participate in international cooperation.

The 7-day seminar concluded successfully with a grand reception. On the morning of November 13, Xu Qingzhou and the institute's staff boarded a plane to Kyoto.

It happened to be Friday, at 2 PM.

"Finally home."

Xu Qingzhou collapsed onto the sofa, feeling completely relaxed once she returned to her familiar surroundings.

Er Miao remained seated on the sofa in front of the French windows, just like an empress dowager. Only after seeing Xu Qingzhou lie down on the sofa did she nimbly land on the ground and walk over with elegant steps.

"I can't lie down anymore."

After resting for half an hour, Xu Qingzhou got up, changed into a light jacket, and set off for class.

Kyoto University.

I was away on a business trip for a week, and when I came back, the season had changed.

Because it had rained in Kyoto a few days ago, the temperature had dropped considerably, and most of the leaves on the school's ginkgo trees had fallen. Looking around, the yellow camphor leaves and fiery red maple leaves were intertwined, creating a beautiful autumn scene.

Xu Qingzhou walked into the lecture hall, where there were still many people attending the class, and some people were still standing at the back of the classroom.

As soon as he entered, the previously noisy classroom quieted down, and everyone's eyes fell on the young man on the stage.

Riemann guessed that Xu Qingzhou could talk about it with his eyes closed, and with his two lifetimes of teaching experience, he wouldn't even need a lesson plan.

The school bell rang.

"It's time for the old process."

"Those who really want to listen to the lecture can stay. If you just want to take photos and check in, you have half a minute to leave now." Xu Qingzhou's gaze swept around the classroom, and he noticed Song Lulu in the corner by the door.

As soon as he finished speaking, there were scattered sounds in the classroom, and about seven or eight people left.

He confirmed again, "It's about time."

Two people in the audience hesitated for a moment, then bowed and went out.

Looking around and seeing that no one was moving, Xu Qingzhou didn't waste any more time and continued with the previous content: "Previously, we have completed the explanation of the distribution of zeros to the prime number theorem. Today, we will officially enter the calculation of the nontrivial zeros of the Riemann zeta function in the Riemann-Siegel formula."

"The derivation of the Riemann-Siegel formula is not complicated. You can try deriving it yourselves after class. Class time is limited, so I will just give a brief explanation."

The young man's unhurried voice echoed in the large lecture hall.

Upon hearing this, many people in the audience twitched at the corners of their mouths. The derivation of the Riemann-Siegel formula isn't complicated? Excuse me, but was that a bit offensive?

"As you may recall, in the third lesson, we introduced an auxiliary function ξ(z). Now, please recall the algebraic relation: ζ(s) = 2Γ(1-s)(2π)s⁻¹sin(πs/2)ζ(1-s)."

Down in the audience, Song Lulu pondered the equations written by Xu Qingzhou. Although she had studied them on her own before coming, she was still struggling with them.

She couldn't help but admire him. Although her brother-in-law was unreliable in private, he was truly remarkable in his ability to make dry math lessons lively and interesting.

No wonder my roommate is such a fan.

Beside her, Wu Ziyue stared intently at the young man on stage, her eyes sparkling, muttering to herself, "As expected of my idol, just like in the news, gentle and handsome."

She took a deep breath, quickly cleared her mind, and listened attentively.

After 5 minutes.

"Here, the following formula can be proved using the definition of ξ(s)."

"Oh, by the way, you can figure out the specific proof process yourselves; consider it homework."

Down below the stage, Wu Ziyue, who had just been staring at the stars, now had a stiff expression, staring blankly at the formulas on the whiteboard.

"Aba aba~ Who am I? Where am I?"

And so the class ended.

Inside the classroom, Xu Qingzhou answered a few questions from the students. After leaving the classroom, he waited at the stairwell outside to ask Song Lulu if she wanted to go back for dinner together.

Hey~
Before Song Lulu arrived, his phone rang with a message notification.

Song Lulu's message: "Brother-in-law, you just got back from your business trip, so I won't disturb your life with your cousin."

Xu Qingzhou smiled, replied "Okay," then put away his phone and strode away. It's so nice to have such an understanding sister-in-law.

Lecture room.

After replying to the message, Song Lulu looked at the deeply affected Wu Ziyue and asked, "Ziyue, are you alright?"

"I don't understand at all." Wu Ziyue said dejectedly.

Song Lulu was not much different and was mostly in a daze. She comforted her, saying, "It's normal not to understand. The requirement for this class is that you must be at least a junior."

Wu Ziyue understood, and nodded, "This is the difference between humans and gods. Let's go, we won't come again next time."

"Oh, you've given up?" Song Lulu smiled.

"I just feel that coming here again would be a waste of time and take up everyone's resources. I will work hard and apply to Professor Xu's graduate program in the future."

"Having dreams is a good thing."

"Lulu, Xu Shen looked over here several times during class just now."
