The fake heiress loves to act? The max-level boss isn't interested in playing along.

Chen Rui's smile froze.

Fu Hua picked up the chalk and drew a circle on the line of derivation she had just read.

"You made an approximation in the third step, ignoring the boundary conditions."

She explained, "Within the framework of classical mechanics, this approximation leads to nonconservation of energy."

After saying that, she turned around and looked at Chen Rui.

"Competitions test not only problem-solving skills, but also the clarity of physical diagrams. Your thinking is clever, but not rigorous enough."

Chen Rui opened his mouth, as if something was stuck in his throat.

Su Rong gave him this question, and it took him quite a while to figure it out.

You figure out the answer, but when it comes to explaining it to someone else, you're stumped.

He knows how to solve the problem and can deduce the steps.

But the underlying logic—why approach it this way, how did they come up with this step?

He understood it in his heart, but he couldn't express it clearly.

Unexpectedly, Fu Hua's few words were clearly and logically sound.

Every step is crucial, with not a single superfluous word.

The audience was silent for a few seconds, then a buzz of discussion arose.

Chen Rui stood there, his face turning red and white in turns.

He took a deep breath and spoke again.

"Then let me ask another question: In special relativity, why can't particles reach the speed of light?"

But photons have zero rest mass, yet they can travel at the speed of light?

What exactly is the essential difference between these two?

Many people can recite the conclusions of this question, but those who truly understand the principles are one in a million.

Many of the physics students present couldn't understand it at all.

She stood there, her tone calm.

It's like taking the entire theory of relativity apart and showing it to people.

"Many people memorize the conclusions to this problem, but they haven't grasped the root of the issue."

I won't talk about formulas, I'll only talk about the essence.

Her gaze was clear, and she spoke each word distinctly:

"The key to everything is just two words: static mass."

Particles with rest mass

It is on the world line, in timelike motion, and has a "stationary" frame of reference.

It has its own time.

To push it to the speed of light, the energy required would approach infinity.

Therefore, it will never be achieved.

In short, "If you have static mass, you are bound by time."

When your rest mass is zero, you are born with light.

This is physics, the very bottom line.

Below the stage, Su Rong kept her head down.

His brows were furrowed, and his face had already darkened.

She had heard this question before and had memorized the standard answer countless times.

But suddenly someone asks you "why" to your face,

Instead of asking "what is it?", one can only freeze in place.

Formulas, Lorentz factor, energy dissipation, zero rest mass flashed through her mind...

The knowledge points are piled up densely together.

I recognize each of them individually, but when you put them together, it's a complete mess.

She can write out the derivation process, calculate the values, and memorize the conclusions.

But he just can't bring himself to say the most crucial, essential sentence.

The answer was right there on the tip of my tongue.

It's like being blocked by an invisible wall; no matter how hard you try, you can't get it out.

The more she thought about it, the more panicked she became, and the more anxious and confused she got.

Before she could even grasp the logic, Fu Hua had already gotten straight to the point.

Both being physics students, they considered themselves to be among the best of their peers.

But only now do I clearly realize that

They only learned physics.

I didn't understand physics at all.

Su Rong raised her head, looked at the figure standing in front of the blackboard, and her expression changed.

Talent is a truly terrifying thing.

Zhou Ming's pupils contracted slightly, his expression shifting from doubt to shock, his eyes instantly igniting with a burning light.

His fingertips tightened slightly, and a surge of excitement welled up in his chest as he faced a formidable opponent.

The other students looked at each other.

I have absolutely no idea what that question was about.

Professor Li sat in the front row, his face darkening.

He cleared his throat and spoke again.

"Then let me ask you one more question."

He paused, then posed a deeper question.

It involves higher-level content in university physics.

How do you understand the applicability boundaries of classical mechanics and the Lagrange equations?

Someone in the audience gasped.

This is clearly making things difficult for people.

Even graduate students would need to think about this kind of question for a while.

Fu Hua stood on the stage, her face expressionless.

"The Lagrange equations are applicable to holonomic, constrained, and conservative systems."

Her voice was calm and clear, "But it will fail in non-conservative fields, dissipative systems, and high-speed motion. We must introduce generalized forces or directly transition to relativistic mechanics."

She paused, then added a few more sentences.

He pointed out several points that are rarely mentioned in domestic textbooks.

The details you only encounter when doing scientific research.

As Professor Li listened, the expression on his face gradually changed.

The elderly professors around them also looked surprised and exchanged glances.

After Fu Hua finished speaking, she looked at Professor Li.

"Professor Li, what do you think?"

Professor Li opened his mouth, but couldn't say anything for a long time.

There was a few seconds of silence in the audience, and then someone raised their hand.

"Fu, I also have a question."

"I'd also like to ask you about that."

One by one, the students stood up to ask questions.

Fu Hua answered each question one by one, sometimes writing a few strokes on the blackboard, sometimes just speaking a few words.

Gradually, the questioning turned into a discussion.

A student offered their own ideas, and Fu Hua nodded, then pointed out areas for improvement.

A student asked a more in-depth question, which Fu Hua answered.

He then countered with, "Why do you think this place should be handled this way?"

The students in the audience changed their gaze from skepticism to seriousness.

From taking it seriously to admiring it.

Finally, Professor Li stood up and nodded to Professor Lü on the stage.

The Physics Department at Kyoto University truly deserves its reputation as a leading academic institution in the country.

Professor Yan's students are extraordinary.

Professor Lü sat to the side without saying a word.

He glanced at the students, then at the professors, and a slight smile curved his lips.

The students and professors at Huaqing University are ambitious, not just jealous.

Today's discussion is more meaningful than the award itself.

"I have something to announce."

The audience fell silent, and everyone looked at Professor Lü.

"The last two questions in this competition were the most challenging."

Professor Lü said, "It was Fu Hua who helped me with this."

The entire room fell silent.

Chen Rui stood below the stage, his expression frozen.

The students who had just questioned her looked at each other, none of them able to say a word.

The professors who had started the argument changed their expressions repeatedly.

They also said that the physics questions this time were particularly challenging.

I thought Professor Lü had invited a professor from abroad.

Unexpectedly, it was created by Fu Hua.

Su Rong lowered her head, her fingers clenching the hem of her clothes.

Zhou Ming sat in his seat, staring intently at the figure on the stage, his eyes unblinking.

Chen Rui stood there, his face flushed red.

He took a step forward and bowed slightly towards the stage.

"Fu, I'm sorry, I was... offensive just now, I shouldn't have questioned you."

Fu Hua looked at him and shook her head.

"Your willingness to ask questions and dare to question is commendable in itself."

"The most important thing in physics is to dare to think and ask questions, not to blindly follow answers. People who dare to think will always go further than those who only memorize answers."

Professor Lü stood up and loudly echoed, "Student Fu is right. In physics, age and gender are irrelevant; only true ability matters."

There was a few seconds of silence in the audience, then thunderous applause erupted.

Professor Lü picked up his teacup, took a slow sip, and kept his gaze fixed on Fu Hua.
