Back to the 80s Machinery Factory

Chapter 418 Going to the Advanced Mathematics Professor's Office to Make Up for Missed Leave

The advanced mathematics teacher really got angry.

He looked at Tao Runze and narrowed his eyes: "Tell him to come to my office after class, or he can forget about passing the final exam!"

"I understand, teacher. I'll tell him."

Tao Runze, who had been innocently caught in the crossfire, sat back down on the stool, silently worrying for Chen Luyang.

...If you say you don't understand, then you don't understand. Why are you skipping class?
This morning, Chen Luyang, for some unknown reason, insisted on auditing a class in the Department of Mechanics.

He also said that if the advanced mathematics teacher asked him about it, he would just make up a reason for himself.

Anyway, advanced mathematics is a large class, with hundreds of people in one room.
If one or two students are missing, the advanced mathematics teacher might not even notice.

But little did I know that as soon as class started, the advanced mathematics teacher caught me.

Right now,

Chen Luyang, completely unaware that she had angered the advanced mathematics teacher,

He was sitting in the science building, listening attentively to a lecture on "Principles of Machinery".

Compared to yesterday's materials science class, the mechanical principles class was significantly more boring.

Zhang Diancai was a male teacher in his forties, very serious and methodical.

The courses were also very boring and tedious, almost like chanting scriptures.

"The dead-point interference effect in the transmission process of a mechanical system needs to be solved through eccentric wheel or double linkage design..."

He spoke very quickly, like a machine gun, while simultaneously writing on the blackboard.

Before long, the blackboard was densely covered with various structural diagrams: linkage mechanisms, dead point positions, follower trajectory analysis, and a long string of formulas and arrows.

If it were any other student auditing the class, they would probably be terrified at the sight of this scene.

But Chen Luyang, having come from a factory background, had seen more machines than many people had eaten candy.

Although he didn't understand the meaning of many of the technical terms in the course "Principles of Machinery"
But once it's linked to workshop experience, Chen Luyang can hear even the slightest bit of the feeling!
Even if you hear it in a daze, it's not like you can't understand it at all.

...Anyway, it's better than advanced mathematics!!!

Finally, the bell rang, and the get out of class was over.

Chen Luyang remained seated, watching as several students went to the podium to ask Zhang Diancai questions.

Zhang Diancai didn't put on airs; he stood by the podium patiently answering questions. Seeing that he had almost finished explaining...

Chen Luyang took three steps at a time and approached the podium before the last student left.

"Hello, Teacher Zhang! I am Chen Luyang from Class 1, Department of Economics, freshman year."

Zhang Diancai took the book and walked towards the door, clearly having something urgent to attend to.

"Excuse me, is there something you need?"

Chen Luyang immediately followed and kept the conversation brief:
"Teacher, I am a student trained by the provincial machinery factory, and I am currently in charge of the car maintenance and repair center in Pian'ercheng."

Zhang Diancai paused for a moment, seemingly a little surprised, but didn't say anything.

"We are currently working on standardizing common parts, and we want to transform the hand-drawn blueprints of high-frequency small parts such as spark plugs, nozzles, and gaskets into standard industrial drawings that can be circulated and produced."

"But the workers in the workshop rely solely on experience to draw, and all the drawings are hand-drawn sketches. There are no people in the factory to proofread them."

“I was thinking…could you do us a favor and guide us in drawing a batch of industrial standard drawings?”

Zhang Diancai directly refused: "This kind of thing, even a third-year college student can draw."

Chen Luyang continued, "Teacher, I know that our third-year students can draw."

“But we are dealing with too many different car models and a lot of parts now.”

"To achieve mass production standardization, it's not just about drawing blueprints; you also need someone to judge whether the structure is feasible, whether the process is feasible, and whether the data needs to be merged... This is not something an ordinary student can do independently."

Chen Luyang followed Zhang Diancai closely, like a little hamster.

He really felt that his 2.98-meter-long legs were already very long.

But Zhang Diancai, who was less than 1.75 meters tall, charged forward like a whirlwind.

Even Chen Luyang struggled to keep up.

Seeing that Zhang Diancai remained silent,

Chen Luyang gritted her teeth and said, "Teacher, I don't mean to look down on students. Of course, the students from Peking University are more advanced."

"But this isn't an assignment; we want to properly standardize the basic components of automobiles. I really want to find professionals to work with and get something done."

Chen Luyang tried her best to make her tone both sincere and confident, neither humble nor presumptuous.

Unfortunately, although his words sounded sincere, Zhang Diancai clearly didn't have time to listen carefully.

“Your idea is great, but I really don’t have time right now. I can recommend two students to you; they’ve worked on projects with me and are skilled at drawing.”

As they spoke, the two had already walked through the teaching building corridor and arrived at the office area.

Zhang Diancai strode into the office, threw down his lecture notes, gulped down a mouthful of water, then grabbed the keys from the table and put them in his pocket.
"I have to go to a meeting at the research institute now, we'll talk about it another day."

After saying that, he turned and left the office without looking back, not even leaving Chen Luyang with a glimpse of his back.

Chen Luyang wanted to say a few more words.
But Zhang Diancai had already rushed down the corridor like the wind and headed straight downstairs.

Chen Luyang watched as the other person turned and went into the bicycle shed, pushed out the large 28-inch bicycle, and with a squeak, sped out of the school gate and disappeared around the corner of the street.

"...This teacher is not easy to deal with."

Chen Luyang stood on campus, her brows furrowing slightly.

It's not that you can't hire students.

but……

With such an amazing teacher, who would want to find students?
The students in the mechanics department are certainly not bad.

However, the school's teaching is mainly theoretical, and most students have never even been to a workshop, let alone dealt with front-line equipment.

Although they can draw, their skills are mostly limited to classroom exercises, and they draw the standard exercises from textbooks.

It can be said that students' "blueprints" are "textbook-style," while teachers' blueprints are so detailed that "the workshop can start production by following them."

And the most important point!

The drawings not only need to be drawn, but also need to be understood in terms of "whether it can be done, how to process it, and where it is easy to make mistakes".

Like a nozzle diagram,

Professional teachers and engineers can tell at a glance which tool is best for making the inner hole on the lathe, and which stress concentration areas the rubber gasket should avoid when adjusting its thickness.
But the students may have only drawn the outline according to the sketch, and didn't even know whether or not to add "bevels".

Not to mention the standardization of standard parts.

A single image must not only be visually appealing, but also reusable, compatible with the warehouse's part number system, adaptable to different vehicle models, and capable of controlling processing costs, material waste, and even transportation difficulties.

Ultimately, this is not about drawing "a part drawing".

Instead, it aims to build "a replicable and scalable industrial drawing system".

Students can participate in this system, but they have no way to take the lead.

Only teachers can truly translate "ideas" into "engineering language".
Chen Luyang remained silent for a few seconds.

If Zhang Diancai is unwilling to deal with him now, then let's try a different approach and find a way to take him down!

He stared at the empty stairwell in the distance, his gaze gradually hardening.

"I need to figure out a way..."

……

Bedroom
Chen Luyang pushed open the dormitory door, but before she could even speak...

Then he saw that everyone in room 421 stopped what they were doing and stared at him.

Their faces displayed a complex mix of expressions, including sympathy and schadenfreude.

"what is wrong?"

Chen Luyang glanced at them suspiciously: "Why are you all looking at me like that?" "Little Chen~" Tao Runze looked at Chen Luyang sympathetically: "You didn't go to your advanced mathematics class today, and Teacher Zhang found out."

What? ? ?
Chen Luyang's forehead suddenly buzzed.

That advanced mathematics classroom holds two or three hundred people; let alone someone like Chen Luyang, he wouldn't go.

Even if the entire 421 dorm didn't go for half a semester, no one would ask.

How did the teacher find out about him?
"Then what?"

A bad feeling welled up in Chen Luyang's heart.

Did Teacher Zhang say anything?

He said he wants you to come to his office.

"...!!!"

Chen Luyang's head trembled as he listened.

He froze on the spot, his mouth slowly opening.

Tao Runze repeated what he had just said.
After repeating it, Tao Runze even said to him in a seemingly comforting tone:
"You really have to be Chen, the teacher worries about you if you miss a class."

"If you're like us, you could skip half a semester and the teacher probably wouldn't even notice."

Pan Yu chimed in while munching on an apple, "That's right! No wonder our Chen Luyang has such a strong presence; she only missed one class, and the teacher already has her on his mind."

Seeing Chen Luyang's dejected expression,
Jiang Feng, who was standing next to Chen Luyang, stood up with an uncontrollable chuckle, patted Chen Luyang on the shoulder, and said:

"Go ahead, you know the teacher's office best!"

Zhang Dongliang grinned mischievously, "Tao Ge got you sick leave because of diarrhea, so you'd better pretend it's real and not be too healthy."

……

Listening to those bastards from 421 making sarcastic remarks one after another.

Chen Luyang suddenly felt everything go black.

The sky is falling.

……

Comrade Chen Luyang is a true hero who was born in a machinery factory, grew up on various award stages, and can enter and leave his future father-in-law's house as if it were his own territory!
Just today,

I experienced what fear truly is!

"Can't we just not go...?"

Holding onto the last glimmer of hope, Chen Luyang's voice trembled slightly.

"If you don't go, you might not pass your final exams," Wu Dechen added casually, smiling kindly.

"I...but I don't know which office he's in either," Chen Luyang tried to make a last-ditch effort.
At this moment, Pan Yu stood up and spoke a fair word:

"I've already asked about room 327 in building 1 for you. You can just go there directly."

Chen Luyang: ...

Damn it!!!

"Thank you, kind person," Chen Luyang said through gritted teeth.

He glared fiercely at Pan Yu, then strode heavily out of the dormitory.

Jiang Feng shouted from behind, "Pay attention to the details! It's diarrhea!!"

The dormitory door slammed shut.

……

The atmosphere in the advanced mathematics office was as serious and quiet as ever.

Teacher Zhang is grading students' homework one by one.

Out of habit,

After each get out of class, he would leave two thought-provoking questions as homework, asking the students to think about them thoroughly and use their divergent thinking to solve them.

He can also adjust the depth and pace of the next lesson based on the students' homework.

He has always maintained that advanced mathematics is not taught to "smart people," but to "people who are willing to listen."

But... there's nothing I can do.

Unlike other disciplines.

Advanced mathematics is something you either know or you don't.

It's not like they'll just pry open your head and pour the contents in.

Your brain is like a sponge soaked with water; not a single drop can get in.

But even so,
Teacher Zhang, upholding the spirit of never giving up,

I try my best to make my courses easier to understand, so that everyone can comprehend them as much as possible.

For most students who struggle with advanced mathematics, he would carefully revise their work and write down the solution process and learning suggestions at the bottom of their assignments, so that students could understand where they went wrong.

However, looking at Chen Luyang's homework,

On Teacher Zhang's sharp, unforgiving glasses, flashes of ruthless cold light, like lightning bolts, streaked across the lenses!

Whether you understand it or not is one thing!

Whether the attitude is correct or not is another matter entirely!
He can accept that his students might not do well on their assignments because they don't understand the lessons.

However, they cannot tolerate students copying homework or completing tasks perfunctorily!
Judging from Chen Luyang's naive, innocent, and pure demeanor during class,

He didn't believe that Chen Luyang could solve the problem he left behind.

But every time homework is handed in,
Chen Luyang's assignments were all very solid, with complete logic, standardized steps, and even the formulas were written neatly.

Every step is written clearly and thoroughly.
Based on his years of teaching experience, it's clear that this was a student with exceptional talent who, in order to fit Chen Luyang's personal image, deliberately chose the dumbest, most basic, and most idiotic solution and had Chen Luyang copy it into her homework.

Originally, Teacher Zhang intended to say a few words during class.
Who would have thought that Chen Luyang, who usually copies homework, would actually skip class today!
Have loose bowels……

Ghost letter!
Just then, there was a soft knock on the door.

dong dong dong...

Several teachers in the office glanced instinctively toward the door.

A tall male student stood at the door, looking like a little quail, and greeted us with a sheepish smile.

"Hello, Teacher Zhang... I'm here to request leave."

snort!
Teacher Zhang snorted and turned back to grading homework.

I don't know if it was just Chen Luyang's imagination,

Just now, when Teacher Zhang turned around, he seemed to feel that the other party glared at him.

"Teacher, I'm here to make up for the missed leave."

Chen Luyang steeled herself and walked to Teacher Zhang's desk, beginning to frantically explain to herself:

"Teacher... I ate spicy fried noodles last night, and my stomach wasn't feeling well, so I didn't go to class today."

Teacher Zhang didn't even look up; she just kept staring at the homework in her hand.

"I really didn't skip class on purpose," Chen Luyang quickly added when the other person remained silent.

Under this quiet pressure,

Just as Chen Luyang was preparing to accept all the criticisms from her advanced mathematics teacher,
Suddenly, Teacher Zhang spoke with a half-smile:
"You did a great job on your homework."

Chen Luyang: Huh? What do you mean?
He looked down as if possessed!
I'm crazy
Teacher Zhang was looking at his own homework!
"That's all thanks to the teacher's excellent teaching..."

Chen Luyang answered almost instinctively, determined not to let the teacher's words fall to the ground.

Teacher Zhang nodded, then suddenly pointed to a formula in the workbook and asked him:
"Why did you use L'Hôpital's rule instead of the squeeze theorem when finding the limit in this step of your problem?"
