Chapter 575: 227 Who dares to speak up? The building butler saw Principal Shi_1

He Wen settled back into his seat, his gaze sweeping across Chen Hong and Xu Wenyao.

He had spent nearly a year in the lab, and his complexion was a pale, cold white. There weren’t many people in the coffee shop, the lighting was dim, and as it shone on him, the breathing of both Xu Wenyao and Chen Hong became noticeably lighter.

He Wen had chosen a seat by the window.

The table was a rectangular piece of raw wood, one end up against the floor-to-ceiling window, with a single stool set apart at the end facing the window. Bai Lian was sitting on this solitary stool.

Her left hand rested casually on the armrest, her demeanor composed and unhurried.

Yu Guang saw that Xu Wenyao and Chen Hong were still standing where they were, so she tilted her chin up at them, signaling them to sit across from He Wen.

“What’s the topic this year?” He Wen pushed his laptop aside and turned his head to speak to Bai Lian. He didn’t ask whether they had chosen Question A or C.

As he spoke, Chen Hong and Xu Wenyao finally snapped back to reality. Instinctively, they both thought to take out their phones to show He Wen the question.

“Astronomical telescopes…” Bai Lian set down her milk tea, her fingertips tapping rhythmically against the cup, “given the parabola of a star’s position with a radius of 300, achieve the optimal reception effect for light rays being received.”

As she explained the problem to He Wen, Xu Wenyao and Chen Hong couldn’t help but look down and open the question saved on their phones.

Question A was complex, with four original working diagrams. Chen Hong had looked at it once; he wasn’t even clear about the work diagram of the telescope.

When Bai Lian announced several numbers, he hurriedly flipped to the second page’s diagram—

300, 0.466.

Not a single figure was off.

Not only had she understood Question A in a short time, but she even remembered the focal data of the approximate paraboloid formed by the reflecting panel when observing celestial bodies.

“An active reflector model?” He Wen lowered his eyes slightly, pondering, “The problem doesn’t sound complicated based on the description. It has over two thousand cables, so you need to construct functions in over two thousand dimensions, then establish a continuous function from the discrepancy between the later constructed cables and the target? Simulated annealing is accurate and can also quickly produce an answer.”

Bai Lian slowly revolved her milk tea, her fingertips gently tapping the cup as she shook her head, “I think the nodes might all be on the ideal parabolic surface after adjustment, but even if they are, it’s meaningless in practice. Using a two-dimensional method to calculate the ideal paraboloid and the radial distance, the reception is different from what we thought. Solving the azimuth linearly, the received ratio obtained is different from the discriminant, which can be integrated.”

She did not choose the solution proposed by He Wen, clearly having developed her own complete approach on the way.

The two spoke quickly, and Chen Hong and Xu Wenyao were not following very clearly.

He Wen understood, “You’re going to use Monte Carlo Integration?”

The two sat and chatted casually, quickly setting the general direction for the entire mathematical model.

Bai Lian leaned slightly against the back of her chair, one hand resting casually on the armrest. She was dressed in simple, elegant clothes, her eyes and brows relaxed, exuding a restrained temperament yet full of a commanding presence.

This effortless display of grace was captivating.

Talent indeed shone brighter than anything else.

Xu Wenyao could still understand, but Chen Hong was not even clear about the problem, and he found it a bit difficult to follow.

After they finished their conversation, He Wen’s gaze landed on Xu Wenyao, “Are you responsible for running the code?”

Xu Wenyao, after all, had more experience than Chen Hong. He came back to his senses, “Yes.”

“In math modeling, instructors cannot participate too much,” He Wen closed his laptop, his concerns not for Bai Lian but for her teammates, “She won’t have any issues with the general direction. If you cannot run the code to get an answer, try to construct one; otherwise, use various regression models and the BFGS algorithm…”

Coding was Bai Lian’s weakness, which was also why she sought out He Wen.

While He Wen was discussing with Xu Wenyao, Bai Lian opened a blank document on her phone to analyze the three problems.

With only three days to confirm the model, run the code, and write the paper, time was tight.

It was past ten in the evening.

He Wen and Xu Wenyao had not yet finished their discussion when Bai Lian glanced at the time. She hadn’t brought her computer, which made it inconvenient to construct the model, so she left early.

It was quite late at this point, and He Wen had just returned to Jiangjing. He didn’t ask where Bai Lian lived, but when he saw her getting ready to leave, he instinctively stood up.

“You guys continue talking,” Bai Lian knew He Wen wanted to escort her. She gestured for He Wen to sit down, “Don’t worry about me.”

Jiang Fulai was waiting for her at the intersection.

Midnight.

Xu Wenyao and Chen Hong stood downstairs, watching He Wen enter the dormitory building. They waited until He Wen’s figure disappeared from sight before Chen Hong pinched his own arm, seemingly in a daze, “Is Senior He Wen our mentor?”

Xu Wenyao nodded.
