It’s just an escape show, but you actually want to destroy the world?

"I know that it is because of the military race, after all, in today's world pattern, mastering air supremacy is the top priority for a country, which is the biggest reason for us to study aerospace. "

A female student was the first to answer.

Zhou Jin shook his head and did not speak.

But it's clear that

This answer is not correct.

Another student said: "I think it's to make people move faster, after all, the speed of the plane is the fastest of all means of transportation, and it can ignore the influence of mountains and rivers." "

Zhou Jin shook his head again, not too satisfied with this answer.

"Is it because of nature? After all, having wings and soaring in the air is the most primitive dream of all human beings. "

The voice of the student who spoke was not loud, and he could hear that he was a little weak.

Zhou Jin shook his head again, but this time he didn't let the other students answer again, but walked to the podium, picked up the chalk and wrote two words on the blackboard.

'Selfish. ’

Selfish?

The 100 contestants were stunned when they saw these two words, and they really couldn't understand why the great project of aviation had anything to do with selfishness.

Elementary school student Kudo frowned slightly, he felt that if he hadn't guessed wrong, Zhou Jin was going to tell his very confusing and brainwashing speech again.

He wanted to stop it, but now there was no chance for him to speak, so he could only quietly observe the surrounding terrain to determine which path would be smoother if he wanted to run later.

"Teacher, I don't understand what this means!"

"Yes, we are all determined to devote ourselves to the aviation field and love the aerospace industry, how can it be related to selfishness. "

"It's like, I don't think it's the right word for us, right?"

"Dr. Joker, can you please explain?"

There were several protests in the class, loud and unafraid of being noticed by Dr. Joker.

In the face of doubts, Zhou Jin did not have the slightest weakness or strange emotional changes, but waited until all the students were quiet and asked a question again.

"Students, do anyone know the story of Easter Island?"

As soon as he finished speaking, a student immediately raised his hand: "I know that around 400 A.D., a group of Polynesians sailed out to sea in the eastern Polynesian archipelago, crossed thousands of miles of oceans, and landed on Easter Island, which was the first time that humans discovered the island. "

"That's a good point. Zhou Jin nodded: "Then who knows what happened to Easter Island later?"

The students were a little puzzled, and no one could understand why Professor Joker came up and said that human research on aerospace was because of selfishness.

And then the Easter Island?

What does this have to do with binary vector engines?

However, although they don't understand the meaning, the students basically know something about what happened on Easter Island.

"I remember that after a period of cultivation and fishing at sea, life gradually settled down, but the increase in population led to a shortage of food, so in order to solve the problem, large-scale deforestation began around 800 AD, especially palm trees, which were the best wood for building canoes.

The islanders built a large number of boats to go out to sea to fish, and harvested a lot of fish and dolphins and other aquatic products, as for what happened later, I don't remember either.."

A female classmate quickly explained what she remembered.

Zhou Jin nodded slightly, did not stop, and asked again: "Later, does anyone know what happened?"

"Dr. Joker, I know!"

"At that time, the rapid increase in the population of Easter Island caused the depletion of natural resources, which gradually exceeded the carrying capacity of local resources. As a result, conflicts and wars broke out between the tribes over the limited resources, and there are now many stone spears and stone daggers left in the soil of the island.

Around 1200, the tribes built huge stone statues to establish the worship of their chiefs, and deforestation intensified, and a large number of palm trees were cut down for fuel wood and transportation stone statues, and the number of sea catches began to decrease during this period.

In 1400 AD, the palm trees disappeared and by the end of the 15th century the island was completely deforested. Birds are starting to decline due to lack of food, and many plants are becoming extinct due to the loss of pollination.

As people lacked trees to build boats, their seafaring skills gradually deteriorated, and even a few canoes remained on the island, so the islanders turned to reclaiming wasteland to grow grain, but they still could not meet the people's food supply.

As a result, the originally more developed civilization began to decline, and cannibal tribes gradually appeared.

Biologists found in the garbage heaps of the islanders that from the 15th century, the number of human bones increased, indicating that there was a cannibalism In 1700, the population began to decline to 1/5 of the original population, and people began to live in caves to defend against enemies.

In 1770, rival tribes began to tear down and destroy each other's huge "Mao Ai" stone statues in order to break each other's spirit and fighting spirit. In 1830, the last stone statue also fell.

By the beginning of the 20th century, living conditions were already very poor, with only 111 indigenous people remaining. "

The last student was very knowledgeable and talked about almost all the important things that happened on Easter Island.

meantime

Everyone's attention was once again on Zhou Jin, wanting to know why he suddenly mentioned such an obscure island.

In fact, there are many islands similar to Easter Island, and Easter Island is just one of the most famous.

And under the gaze of all the students, Zhou Jin walked back to the podium and wrote a sentence, or a question, on the blackboard.

'Isn't the world we live in a bigger Easter Island?'

After writing, Zhou Jin stood aside and gave the students some time to think.

......

At the same time, in the live broadcast room.

"My God, I suddenly feel that what Zhou Jin said is right, isn't our world also fighting each other, fighting, and plundering resources? "

"How to say... Will we disappear someday in the future?"

“.... It's scary to think about ———— . "

"So... Zhou Jin's madness and informality are due to the fact that he has seen through the essence of human beings?"

"Selfish... Yes, humans are quite selfish. "

"My God, Zhou Jin.... This... It's a big pattern. "

"I was fascinated by the listening. "

"Y1S1, why didn't Zhou Jin choose to disguise himself as a doctor of history, I feel that he has the strength to explain history. "

"It's pretty impressive... But did you notice a question, Zhou Jin didn't seem to say a few words during the whole process, and this has nothing to do with aerospace, right?"

........

At the same time, inside the virtual escape capsule.

Classroom.

The classroom was quiet for more than ten seconds, and the students all felt a chill down their spines.

They basically knew about Easter Island, but they didn't associate it with the changes in the whole world.

Now Zhou Jin's words made them feel like they were suddenly opened.

At this time, Zhou Jin did not wait for the students to ask, and spoke again, "If human beings, as a species and a civilization, want to survive and avoid a tragic end, they must cast their eyes and energy to the sea of stars above their heads, just as the Polynesians of Easter Island must cast their hopes of life to the vast Pacific Ocean." "

"That's why we humans are committed to the field of aerospace, and that's why I tell you that human motivation actually comes from a selfish heart. "

Syllable... Syllable.... Boom la la la .....

The classroom was clapping again, and it was even more enthusiastic than the last time.

When elementary school student Kudo saw this scene, he couldn't help but complain: "It's obvious that the students are asking and answering themselves, Zhou Jin is really a master of inducing." "

He is a smart person, and he knows very well that Zhou Jin just used the example of the so-called Easter Island, just to let the students think for themselves.

I have to say,

In this way, it is a good start to this lesson.

But the next student question session is the real focus, if Zhou Jin can't answer, or if there is any question, he will also goof.

.......

When the applause stopped, one student volunteered to stand up.

"Hello Dr. Joker, I'm a senior and I've been working on vector engines recently, you're from Houston College, can you please talk about why the F-22 stealth fighter uses a binary thrust vectoring nozzle instead of an omnidirectional thrust vectoring nozzle?"

This is an extremely hardcore question, and it is also a question that can find out the strength of the lecturer.

When this question was raised, even Principal Gu couldn't help but feel a little spirited, everyone wanted to know what kind of answer Zhou Jin would give in the face of this question!

Elementary school student Kudo frowned slightly, and he had already begun to think about how to avoid Zhou Jin's narration.

"Fake sick?"

"Hmm... This should work. "

Kudo, an elementary school student, plans to pretend to be unconscious, so that the lecture can be suspended, and Zhou Jin has a reason and a necessity to send him to the school's infirmary.

Zhou Jin made a good start just now, and it is definitely the best choice to end the teaching now.

At this thought, Kudo, an elementary school student, slowly closed his eyes and prepared to fall straight down and end teaching.

However, just as the elementary school student Kudo was about to act, Zhou Jin's voice sounded again.

He didn't answer directly, nor did he explain from the side, but asked rhetorically, "What do you think is the reason?"

The student pondered for a moment and replied, "I think the F-22's binary vector thrust engine, although it caused some of the engine power loss, was able to hide the engine nozzle in the vector baffle, and the infrared and radar signatures were relatively small, and the stealth performance was better." "

After hearing the student's answer, Zhou Jin shook his head and said, "What you said is not entirely right, because your question did not exist from the beginning, how do you know that the F22 only has a binary vector thrust engine module?"

The female student was stunned for a moment, and subconsciously asked, "What do you mean..."

Zhou Jin waved his hand and stopped the female classmate from continuing to ask: "This question involves engine patent technology, I'm sorry I can only talk about it here, are there any other questions?"

In fact, it is not the design of the patented technology, it is entirely because Zhou Jin does not understand it at all, and if he talks about it in depth, he will inevitably be exposed.

But it doesn't matter if he doesn't understand, he can provide a plausible answer for the other party to guess, and at the same time make all the students and the principal think that he is unfathomable.

It's not psychology, it's a simple trick of the heart.

Anyway, for Zhou Jin, he couldn't and wouldn't stay in this school for a long time, enough to fool them for a few days.

That's all Zhou Jin's plan,

It's adventurous, it's crazy, it's dangerous..... But it's also fun.

In the end, what was supposed to be only one hour of teaching was spontaneously extended to three hours by the students.

During the whole process, Zhou Jin was able to answer questions fluently, and inspired students to generate new ideas, and because of the humorous relationship, the students even forgot the passage of time.

Not even 100 students, even the 80 million viewers in the live broadcast room, Bingbing, the host of the main live broadcast room, and other staff members didn't realize a problem until the lecture ended.

Well?!

Yes....

That's not right,

Isn't Zhou Jin a fake doctor? Why is the lecture so interesting that it still makes people feel unsatisfied?

For a time, it caused a heated discussion on the whole network!
