Chapter 32 Then he's senile.
Gu Feiyu threw down the chalk and clapped his hands. "But what I regret is that our top scorer in the national science exam this year seems to lack even the most basic scientific attitude when faced with this question."
He picked up Lin Yu's exam paper and showed it to everyone.
"Only three lines of formula were written. The last line even contained a model error."
Gu Feiyu stared at Lin Yu in the last row, his tone stern, "Lin Yu, you can leave it blank if you can't answer it, but questioning the question itself, is that just an excuse to cover up your ignorance?"
All two hundred pairs of eyes in the room were fixed on Lin Yu.
Lin Yu turned off his phone screen and took off his earphones.
"You pushed half the blackboard full of stuff; you really worked hard."
Lin Yu stood up, his voice calm and utterly unwavering. "But you've gotten even the most basic boundary conditions wrong. Under extremely strong magnetic fields, the topological collapse of a superconducting interferometer causes the decoherence time to reverse into a negative value. In your model, time has become negative. Are you studying physics or cultivating immortality?"
A suppressed burst of laughter erupted in the lecture hall, which quickly fell silent.
Gu Feiyu's face flushed red instantly, his anger rising to his head.
"Nonsense! Topological collapse has absolutely no impact on macroscopic decoherence time! This is a major direction personally confirmed by Academician Zhang. How dare you, a freshman who hasn't even studied the four major branches of mechanics, spout such nonsense here?"
"Zhang Chengzhi confirmed it?"
Lin Yu left his seat and walked down the aisle. "Then he's getting senile."
hiss--
The entire audience gasped.
He called Zhang Chengzhi by his full name and even called him senile! This kid's gone mad!
"How dare you!"
Gu Feiyu pointed at Lin Yu, his hand trembling.
"Am I being presumptuous?"
Lin Yu walked to the front of the classroom, picked up a piece of chalk, and said, "Open your eyes wide and look carefully."
Next to the equations that Gu Feiyu had written covering most of the blackboard, he wrote only a very simple integral.
"Substitute your pile of garbage into this boundary condition. Calculate the result."
Lin Yu threw the chalk at Gu Feiyu's feet.
Gu Feiyu gritted his teeth, staring intently at the integral expression. He quickly began mental calculations.
One step, two steps...
Suddenly, his pupils contracted sharply. The denominator became zero. A singularity!
The entire function model collapsed immediately after this extreme value condition was substituted.
The decoherence time has indeed become a negative number.
Gu Feiyu broke out in a cold sweat. This is impossible! He'd been working on this project for half a year, writing hundreds of pages of drafts. How could there be such a fatal flaw in its underlying structure?
Just then, the handle of the back door of the lecture hall was pressed down hard.
An elderly man with gray hair, wearing a worn-out gray jacket, pushed open the door and entered. He was carrying a tattered briefcase, his face was ashen, and his eyes were as sharp as an eagle's.
Academician Zhang Chengzhi.
The pillar of the physics department.
"Who said I'm senile?"
Zhang Chengzhi's voice wasn't loud, but it was so loud that the entire classroom stopped breathing.
Gu Feiyu felt as if he had been granted a pardon and hurriedly went to greet him: "Professor! Lin Yu is disrupting class discipline and even insulting your research model..."
"Shut up!"
Zhang Chengzhi didn't even glance at Gu Feiyu before striding to the front of the class. His gaze was fixed on the blackboard, staring intently at the simplified integral formula written by Lin Yu.
Zhang Chengzhi stood in front of the blackboard for a full minute without moving.
The entire lecture hall was so quiet you could hear the whooshing of the air conditioner vents. Gu Feiyu stood to one side, a cold smile playing on his lips. He was certain that Academician Zhang would definitely kick this arrogant freshman out of Jinghua University.
Lin Yu stood with his hands in his pockets, his posture relaxed, letting Zhang Chengzhi stare at the blackboard.
Give me the chalk.
Zhang Chengzhi suddenly reached out.
Gu Feiyu quickly picked up the chalk from the ground and handed it over.
Zhang Chengzhi didn't take it. Instead, he grabbed half a new piece of chalk from the chalk box and turned around to frantically do calculations on the blank space of the blackboard.
The chalk struck the blackboard, making a dense, rhythmic tapping sound.
Zhang Chengzhi wrote formulas faster and faster on the blackboard, his forehead veins bulging.
Gu Feiyu's cold smile gradually froze as he looked at his mentor's derivation. This was because Zhang Chengzhi's derivation followed Lin Yu's integral formula.
Five minutes later, Zhang Chengzhi threw away the chalk.
The result came out.
t = -0.043s
negative number.
It really is a negative number.
Zhang Chengzhi turned around, his chest heaving violently, his gray jacket covered in chalk dust. He looked at Lin Yu, his eyes showing no anger, only an extreme shock as if he had seen a ghost.
"The singularity of this boundary condition is hidden in an eleven-dimensional topological manifold."
Zhang Chengzhi's voice was hoarse, "Our team used three supercomputers and ran them for two months without finding anything. How did you figure it out?"
Lin Yu pointed to the test paper on the podium: "Mental arithmetic."
Upon hearing those two words, Gu Feiyu felt a buzzing in his head, his legs went weak, and he almost collapsed against the blackboard.
Mental arithmetic of eleven-dimensional topological manifolds? This is beyond the human brain!
Zhang Chengzhi took a deep breath, suppressing the turmoil in his heart. He looked at Lin Yu, and a smile that was more like a grimace suddenly appeared on his usually stern face.
"Director Wang isn't lying to me. You can make mistakes with the Casimir effect model, and you can make mistakes with this decoherence model too. Where exactly does your knowledge system come from?"
"It's just common sense."
Lin Yu's tone was indifferent.
Xia Zijing pushed up her non-existent glasses from below. What kind of common sense is that? This way of communicating is definitely Lin Yu's style.
"common sense?"
Zhang Chengzhi burst into laughter, the sound echoing in the empty classroom. "What a convenient phrase! Gu Feiyu!"
Gu Feiyu shuddered: "Mentor... tutor..."
"Erase the blackboard. Your teaching assistant status is revoked, and you no longer need to participate in this sub-project."
Zhang Chengzhi's gaze towards Gu Feiyu had lost its previous appreciation. "He can't even spot a flaw in a basic model, yet he dares to use it to test freshmen? What a disgrace!"
Gu Feiyu was struck dumb, his face turning deathly pale. He knew that his place in Zhang Chengzhi's heart was completely ruined. And all of this was thanks to this freshman in front of him. He clenched his fists so tightly that his nails almost dug into his flesh.
Zhang Chengzhi ignored Gu Feiyu's despair, turned to face Lin Yu, took out a pure black magnetic card from his worn briefcase, and slammed it on the podium.
"National key laboratory, highest level of access control."
Zhang Chengzhi stared at Lin Yu. "You can use the Tianhe cluster's computing power nodes as you see fit. No need to queue, no need for approval. But remember this: I want to see the results!"
Lin Yu stepped forward and picked up the black card.
He ran his fingertips along the edge of the card and nodded in satisfaction.
"OK."
Lin Yu turned around and walked out of the lecture hall.
As he passed Xia Zijin's seat, he tapped on the table.
"Let's go, labor force. Go run your high-dimensional model."
Xia Zijing simply slung her shoulder bag over her shoulder and followed behind Lin Yu.
More than two hundred freshmen, along with a pale-faced Gu Feiyu, watched the two figures depart.
A perfect scorer? No. After today, the entire capital city will know that a monster has arrived in the physics department who can use absolute computing power to rub academicians against the blackboard.
……
Stepping out of the teaching building, the sunlight was blinding.
Xia Zijing looked at the black card in Lin Yu's hand: "You got the highest level of access on the first day. What games are you planning to play next?"
"Let's set up a server first."
Lin Yu casually stuffed the black card into his school uniform pocket. "Old Zhang has too much idle computing power. I'll borrow it to run a new underlying compression algorithm. These days, monetizing technology is the real currency."
Xia Zijing nodded. Communication between top students doesn't need lengthy explanations. Algorithms, data, computing power. That's enough.
"Gu Feiyu will definitely use his authority in the student council to trip you up for the large team project at the end of the semester."
Xia Zijin reminded her.
"That's a good thing."
Lin Yu, facing the sunlight, tugged at the collar of his school uniform. "If the game is too easy, it's not fun."
