Redemption from the Abyss: The School Beauty Insists on Pulling Me Out of the Mire

He held up two fingers, his tone aggressive:

"For the first round, physics, I'll give Ms. Su a question."

"In the second round, computer science, Justin gave a question to this... unknown boyfriend."

"Of course, to be fair, you can also give us questions."

Austin sneered, clearly not taking them seriously.

"You win if you can solve our problem first."

"What's the stake?"

"If you lose."

Austin looked at Su Qinghe, a wicked smile curling at the corner of his mouth:

"Prove I'm qualified to teach you—you must unconditionally give me your contact information and have dinner with me."

"What if you lose?" Su Qinghe suddenly asked, her voice clear and crisp.

"I'll lose?" Austin asked as if he'd heard a joke. "OK, if I lose, I take back everything I just said, and in front of the entire school, I'll apologize to you, and this person..."

He glanced at Xie Wang with disdain:

"And this boyfriend bowed and apologized. He even admitted on Twitter that Saint Philippe is not as good as you."

"Director Yan, this..." Director Yan was anxious. If they lost, they would have to pay for the female students' dinner. How could that be proper!

"Director Yan, don't worry."

Su Qinghe interrupted Director Yan.

She slowly stood up. Although she was a head shorter than Austin, her academic aura, which emanated from her very bones, was in no way inferior.

She looked at Austin, her eyes sharp as knives:

"make a deal."

"However, I hope your knees are flexible enough so you don't strain your back when you bow later."

"In that case, ladies first."

Austin took out a strangely shaped metal device filled with intricate gears and magnetic structures from the metal case he was carrying, and slammed it heavily onto the table with a "bang".

It was an extremely complex double pendulum structure, but each node was fitted with a miniature magnet, and the base had an irregular magnetic field generator.

"This is our latest research project at the St. Philip's Physics Laboratory—a nonlinear magnetic chaotic double pendulum."

Austin pointed to the device that was making random movements, his face filled with absolute confidence:

"Here's the problem: I need you to calculate the coordinates of the double pendulum's trajectory during its 100th cycle within 30 minutes."

"Even in the United States, no more than five high school students can solve the trajectory equation for this model."

Austin crossed his arms and looked down at Su Qinghe:

"Ms. Su, don't just memorize formulas. Please."

The air seemed to freeze.

Director Yan looked at the erratic, shaking lump of iron and felt a chill run down his spine. This was hardly a high school physics problem.

however.

Su Qinghe showed no sign of panic.

She reached out and picked up the complex metal device, her slender fingers gently fiddling with the gear, producing a crisp "click" sound.

She turned her head, glanced at Xie Wang beside her, and a slight smile appeared on her lips:

"Xie Wang, give me the pen."

Xie Wang took a black pen out of his pocket and handed it to her, also smoothing out her draft paper as he did so, his tone lazy and indulgent:

"Teacher Su, go easy on him, don't make him withdrawn."

Su Qinghe took the pen, twirled it between his fingertips, and then looked at Austin:

"Is this your problem?"

"OK."

In the small conference room, only the sound of pen nibs scratching could be heard.

Director Yan was so nervous that he didn't dare to breathe, staring intently at the draft paper in Su Qinghe's hand.

Although he couldn't understand those Greek letters that looked like gibberish, he could sense that Su Qinghe's aura had changed.

At this moment, she was no longer the quiet high school girl.

Her gaze was focused and cold.

Austin, sitting opposite him, initially had his legs crossed and looked disdainful.

He looked at the first line of formula that Su Qinghe had written on the paper:

"Lagrangian mechanics?"

Austin chuckled and shook his head:

"Don't waste your energy. This double pendulum system has been subjected to nonlinear magnetic field interference, making it a typical chaotic system. It cannot be solved using conventional analytical methods; numerical simulation is necessary."

He pointed to the laptop next to him, a look of superiority on his face:

"In the US, we use Python to model and run data. You actually want to calculate it by hand? That's like trying to calculate the trajectory of a nuclear bomb with an abacus, it's simply..."

"Shut up."

Su Qinghe didn't even raise his head, coldly uttering two words.

Her pen moved at an undiminished speed, in fact, it became faster and faster.

Austin was taken aback, his face darkening: "Fine, let's see how long you can keep up this act."

Five minutes passed.

Su Qinghe filled the first page of draft paper.

Ten minutes have passed.

She turned to the second page.

Austin, who had been watching the spectacle with amusement, suddenly froze.

He discovered that he was actually struggling to keep up with the formulas written by Su Qinghe.

That's not just the Lagrange equation.

She introduced a peculiar perturbation term into the equation, which acted like a key, cleverly avoiding the complex chaotic calculations and directly addressing the core singularity of the system.

"Wait... (wait...)"

Austin sat bolt upright, his eyes fixed on the formula:

She is simplifying the Hamiltonian...

"How is that possible?"

"alright."

Fifteen minutes.

It only took fifteen minutes.

Su Qinghe put down his pen.

She gently blew on the ink on the paper, then pushed the draft paper in front of Austin.

Finally, at the very bottom of the paper, she circled a coordinate value:

Su Qinghe put down his pen, rubbed his slightly sore wrist, and said in a calm tone:

"This is the phase coordinate for the 100th cycle that you requested."

Austin was stunned.

He looked at the overly concise answer and instinctively retorted:

"Impossible! This model requires a huge amount of computation. How could you possibly calculate it by hand in fifteen minutes? You must have just written it randomly!"

"write without basis?"

Su Qinghe leaned back in his chair, arms crossed, a faint sneer playing on his lips:

"Justin, isn't your computer on? Just run a data test and you'll know."

Justin, the bespectacled man who had been silent the whole time, opened the physics simulation software with a serious expression.

He entered the initial parameters, and then entered the perturbation term given by Su Qinghe.

Press the Enter key.

The progress bar on the screen moved rapidly.

Three seconds later.

The simulation results are in.

On the screen, the virtual pendulum, after swinging wildly and erratically, stopped precisely at the coordinates calculated by Su Qinghe on the 100th cycle.

Error value: 0.0001%.

"Holy sh*t..."

Justin stared at the screen, his hand trembling as he pushed up his glasses, and a swear word slipped out of his mouth.

He turned his head, looked at Austin's deathly pale face, and swallowed hard.

She is right.

"Completely correct."

Austin felt like he had been slapped hard across the face.

He stubbornly grabbed the draft paper, pointed to a line of steps in the middle, and roared:

"This isn't right! Why is air resistance being ignored? Our model is operating at standard atmospheric pressure!"

"It seems your 'elite education' is nothing special after all."

Su Qinghe looked at him calmly, a hint of pity in her eyes:

"Didn't you notice? The frequency of that magnetic field generator is 50Hz. In the 13th cycle, it resonates and cancels out the damping term of air resistance."

"So I didn't ignore the resistance; I eliminated it."

Su Qinghe pointed to his head:

"Physics is not about rote calculation, it's about understanding."

"You can't even see this basic resonance, and you want to teach me?"
