In 1978, I was admitted to Harbin Institute of Technology

Chapter 74 Canard, big triangle, engine droop! Toys?
"Look, just like in a notebook, first create a two-dimensional plane with XY as the horizontal and vertical axes. Draw the curve of the function F(x) on the plane... Then, in your mind, turn it over like a piece of paper, based on the XY plane, and then derive the Z axis perpendicular to the plane..."

Xie Rou was drawing and talking at the same time.

After hearing this, many classmates around gathered around and started to watch.

At the beginning, Mo Lingyu could still follow Xie Rou's ideas and build two-dimensional function graphs in his mind.

As the content and data increased, my mind became increasingly confused.

When Xie Rou said to add the Z axis to establish a three-dimensional geometric space, I could still understand it.

But when Xie Rou talked about how to introduce other function graphs and associate them with previous functions, Mo Lingyu's mind went blank and he felt like his head was going to explode.

"Beautiful sister, am I making myself clear?"

After Xie Rou finished speaking, you could hear a pin drop in the classroom.

At this moment, everyone intuitively felt how terrifying the efficient learning method that Xie Wei introduced to everyone on the first day of school was.

Although Xie Rou said in the end, almost no one can construct a complex three-dimensional geometric surface in their mind.

Previously, I had learned about various two-dimensional surfaces and function graphs, and I quickly built models in my mind...

The method is clearly explained.

But the content...

"Is this what the monitor meant by turning the knowledge we put into our heads from input into output?"

"No wonder, he has an efficient learning method since he was young!"

"It seems that we are really stupid. When we were studying before, we never thought that we could construct a function curve in our minds. If we construct it in our minds, we don't have to deduce it laboriously..."

Hearing the discussions of his classmates around him, Xie Wei breathed a sigh of relief.

Xie Rou gave him a lot of embarrassment today.

It also gave Xie Wei an unexpected surprise: in just half a year, Xie Rou was able to construct complex three-dimensional geometric figures in her mind.

It’s comparable to the incredible capabilities of computers!

It is not an exaggeration to call it a humanoid computer.

Sure enough, Xie Rou is the real chosen one.

Anyway, Xie Wei can't do it himself.

Perhaps, fighter jets and advanced missile systems can be brought out in advance?
Anyway, Harbin Institute of Technology has a wind tunnel, so the aerodynamic layout can be finalized quickly. The engine and control system projects are already underway.

At that time, let Xie Rou and other people who are good at modeling with their brains build various models in their minds, without having to wait for the computer graphics processing performance to be improved.

The sudden flash of inspiration made Xie Wei's eyes brighter and brighter.

The whole class was very interested in Xie Rou's learning method of building models in her mind.

very good!
Xie Rou will stay here for the next few days. Not only will Xie Rou teach them, but I will also have to spend more time explaining to them how to model in their minds.

If everyone learns what is impossible, as long as there are three or five people in the class, it will be enough.

It is enough for the early stage.

After a while, when I had enough money, I tricked the school into getting a supercomputer with a computing speed of 100 million times per second from the University of Science and Technology of China.

perfect!

"Xie Rou, these questions are basically only learned in college..."

Mo Lingyu looked at Xie Rou and thought of what the class teacher told everyone: Xie Rou studied with Xie Wei every day and slept less than four hours. For a moment, he felt sad for the little girl in front of him who seemed malnourished and sleep-deprived: She must have been fooled by her unreliable brother!
If high school math is so difficult, how many students in the country can graduate from high school?

"My brother said these are the most basic things in high school."

Xie Rou was unhappy when she saw Mo Lingyu saying bad things about her brother.

An expression that said, "I don't want to talk to a fool."

Even though, in her impression, Mo Lingyu was not that stupid.

"Really? If you don't believe me, ask the other students in our class. We haven't learned complex functions yet..."

Mo Lingyu emphasized to Xie Rou.

"Yes! High school is not that difficult." "Your brother must have shown you this year's college entrance examination questions, right? The most difficult one is the quadratic function."

"Our college textbooks only cover the basics of calculus!"

Everyone told the little girl: You were really fooled by your brother! He made you do exercises every day, and your happy childhood was ruined.

Xie Wei on the side looked at everyone and just sighed silently, not bothering to explain.

I'm afraid these people will have to wait until they retire decades later before they can understand the study pressure their children are under.

Xie Wei suddenly thought: When all the classmates in the class have grandchildren, they will probably be driven crazy by the extremely abnormal college entrance examination questions?

For a moment, he began to look forward to what the scene would be like if a group of academician-level bigwigs were worried about their grandchildren's studies.
Really exciting.

"Tsk, do you think I'm stupid? Just because you can't learn in high school doesn't mean you don't have to learn it... For some questions, the textbooks don't explain them, and you have to derive the formulas and processes yourself. You can't derive them, and the teacher doesn't want to discourage you, so he doesn't explain them... When you get to college, the teacher also knows that you can't derive them, so he just prints these formulas in the textbooks..."

Xie Rou had a look of contempt on her face. She glanced at everyone as if they were fools, with her chin tilted 45 degrees towards the sky.

"..."

Well, this little girl treated me like a fool again.

"Xie Ermei, why do you want to learn these?"

Mo Lingyu glanced at Xie Wei, who looked calm, with a complicated look, and suddenly remembered that Xie Wei had rarely appeared in class since the beginning of the school year, except for the entrance examination and the class leader election, but all the students in the class worked hard to study and catch up with him.

For a moment, I deeply suspected that Xie Wei was the monster that had not been caught in previous years!
Didn’t we agree that after the founding of the country, we are not allowed to become spirits?
"Well, my brother said that in order to make this thing, we must master a lot of knowledge in mathematics, physics, and chemistry..."

As for Mo Lingyu, who was not that stupid, Xie Rou did not refuse to explain to her.

She took out a palm-sized silver-white metal airplane model from the floral bag she was carrying.

Liang Hongbin, who had just arrived at the classroom door and was about to remind his classmates that class had started, suddenly widened his eyes when he saw the model in Xie Rou's hand, and he felt as if he had been struck by lightning!
That is……

Fighter model!
"..."

The people around Xie Rou widened their eyes when they saw the model she took out.

Canard.

Delta main wing.

The nose of the plane is slightly drooping, and there is an air intake on the belly that looks like a mouth.

The tail nozzle seems to be slightly downward?

"Why did you bring this thing? Put it away quickly!"

When Xie Wei saw Xie Rou taking this thing out of her schoolbag, he was completely numb!

He hurriedly snatched the metal fighter model from Xie Rou's hand and quickly stuffed it into Xie Rou's floral schoolbag.

My dear ancestor!

Can you easily take this thing out and show it to others?
Looking at Xie Wei's actions and expressions, everyone was confused.

Isn't it just a toy?
The monitor is too nervous!

Few people in the class had ever seen a fighter jet, let alone knew the importance of the model in Xie Rou's hand.

"Uh, squad leader, is that a fighter jet toy?"

Feng Ke looked at the model that Xie Wei put into Xie Rou's pocket and asked in confusion.

It’s just a toy, what’s the big deal?
Haven’t you heard that foreign countries have toys of nuclear submarines for sale?

"Yes, toys! Xie Rou is similar to other girls. She has liked boys' toys since she was a child. I had to prepare for the college entrance examination and had no time to take care of her, so I made her a small toy..."

Xie Wei deliberately emphasized that this was a small toy made casually.

Then, he turned his head and looked at Xie Rou seriously: "I told you, you are in high school now, you are not a child anymore, and you are still showing off your toys to everyone..."

"Brother, didn't you say that if we make this thing, our air force will be able to leap into the forefront of the world's air forces, and no enemy reconnaissance planes will dare to approach our airspace, protecting our motherland's blue sky?"

Xie Rou became anxious.

Isn't the reason I work so hard just to design and manufacture this fighter jet with my brother?
Now Xie Wei says it’s a toy!
