Shocking! This student is phenomenal!

Faced with Su Jiang's outrageous actions, many teachers felt ashamed of themselves.

Putting everything else aside, I feel like even we ourselves can't remember this operation anymore.

Moreover, what Su Jiang wrote was about differential manifolds, which is exactly what was mentioned in the PPT just now.

Therefore, Su Jiang had no time to prepare in advance.

It must be something imprinted in his mind.

The whispers that had been going on in the classroom have now fallen silent.

Especially the older teachers.

They all had their mouths wide open and their eyes bulging out.

He stared blankly at Su Jiang.

I thought to myself: Have I wasted all these years of my life?

Su Jiang, standing on the stage with his back to everyone, had no idea of ​​the expressions on the faces of those below.

About five minutes later.

Su Jiang finally finished writing on the blackboard.

He turned to look at everyone below and began to speak.

These concepts are relevant to anyone from other majors or those who are not strong in mathematics.

Those are things that are simply impossible to understand or comprehend.

If you don't believe me, just go and listen to any third-year math class in the math department; it'll be more soothing than a lullaby.

However, when Su Jiang explained it, these points of knowledge became easy to understand.

Not to mention the teachers who already knew a bit about it, even the underachievers in the classroom...

At this moment, a look of realization appeared on their faces.

Some students even excitedly slammed their fists on the table when the first class ended.

"Holy crap! So that's how it works! After all those math lessons, I'm only just realizing how this concept works!"

"Me too! I feel like I didn't understand any of the previous lessons, but now it's like a revelation!"

"I've come to understand why some classmates said they couldn't understand what the teachers were saying when I was in high school. It turns out there really are good and bad teachers. Good teachers explain things in a simple and easy-to-understand way! Bad teachers explain things in a way that's like listening to gibberish!"

"Yes, some teachers like to show off how knowledgeable they are, saying things that are completely unacceptable to us. What's the point of having teachers like that!"

The students' excited words reached the ears of the teachers nearby.

It was absolutely jarring.

This is a blatant slap in the face!

Isn't this just saying that these guys don't teach well?

Especially the one who was shouting the loudest just now.

The reason he was shouting the loudest was because he was actually in class.

As a result, I was kicked out of class halfway through and had to listen to the lecture.

I was listening to a lecture given by a freshman who was much younger than me.

Do you think this is enjoyable?

However, after hearing Su Jiang's extremely skillful blackboard writing, he had somewhat put away his contempt.

Now, all the students in my classroom are looking and speaking as if they've taken some kind of magic pill and have suddenly gained enlightenment.

His face turned even redder.

If you feel so embarrassed, you could dig a cellar out with your toes and lock yourself inside.

He even felt that some teachers around him were looking at him strangely.

The teacher's name is Kong Dongquan. He is a middle-aged professor in his forties who has studied abroad for many years.

He was a prized student of a famous foreign mathematician.

He never imagined that he, who was doing so well abroad, would encounter such a situation back home.

However, he reacted very quickly.

They immediately found their own strengths.

He immediately retorted:

"Su Jiang may only have a solid foundation in basic knowledge. He hasn't experienced the more profound world of mathematics, so naturally what he says is easier to understand."

"Because we've seen a wider world, we find these things very simple and basic, so when we talk about them, they're not as interesting as his."

Several teachers nearby heard him speak.

The slight embarrassment on her face vanished instantly.

That makes sense!

I spoke quickly and vaguely precisely because I thought it was simple.

In that case, I blame myself for being too knowledgeable and failing to consider the students' feelings.

Then Kong Dongquan continued:

"The most important thing in doing academic research is not to tell students the basics in detail. Once they get to university, they should know how to delve into their own studies."

"And what if, later on, when their knowledge has grown and there's no one left to teach them like this?"

"What teachers need to do is lead students into a new ocean of knowledge. As for how far students can sail, that depends on how much perseverance and dedication they have."

The teachers nearby nodded in agreement.

"Yes, that's exactly it. I hadn't even figured out how to say it yet, but I've always had this feeling."

"That's right, university education is nothing like the exam-oriented education of high school; it all depends on your own research!"

"This is the teaching method I use now, opening the door to profound mathematics for my students. Dongquan understands me!"

Hua Genghao, who was in front, had been taking notes on Su Jiang's method in his notebook.

This is how Su Jiang explained this point.

Su Jiang explained that point of knowledge in this way.

He didn't pay any attention to what the guys behind him were saying.

Su Jiang on the stage simply watched all of this with a cold eye.

Su Jiang heard Kong Dongquan's words clearly.

I thought to myself, "You teacher can't even teach your students properly, yet you're making up so many excuses for yourself."

Even the corners of ancient city walls weren't as thick-skinned as you.

Don't you see that even an academician like Hua Genghao is diligently taking notes?

In a moment, I'll show you what true strength and true mastery are.

The second class started soon.

Su Jiang turned around and started writing on the blackboard again.

A few minutes passed.

Su Jiang threw the chalk into the chalk tray on the side.

Brush the chalk dust off your hands.

Pull the blackboard up.

So that all the students can see it.

Everyone immediately looked up.

Upon seeing it, everyone gasped in shock.

This time it wasn't a knowledge point, but a question.

The question is very simple, consisting of only about two or three lines.

However, the students were completely baffled. They could understand every single word in the question, but they couldn't understand the core concepts at all, let alone solve them.

"Haha, all the students and teachers, this is the question I came up with based on the knowledge of differential manifolds."

"Many students may think that this knowledge point is just a conceptual knowledge point."

"Actually, that's not the case. This knowledge point has a lot of practical significance, such as this question."

"Of course, this question might be a bit difficult for you. You can take a look at it first."

Su Jiang looked at the crowd below and said, half-jokingly.

This question was the most difficult one in Su Jiang's mind regarding the knowledge point of differential manifolds.

He deliberately used this question to test Kong Dongquan's abilities.

What is a true teacher?

"Do any of the teachers here have any thoughts on this problem? Can anyone solve it? How many solutions are there?"

As Su Jiang spoke, he turned his gaze to Kong Dongquan.

"Then how about I ask you to solve this problem? Let your students see what the ocean of knowledge is all about. And let me broaden my horizons too."
