As a school in China to carry out the curriculum planning of university mathematics majors, as early as the early years of the Republic of China, only Peking University set up a mathematics department.

Its courses mainly include differential calculus, differential equations, function theory, modern mathematics, and variational science...... Mathematics exercises, astrology and other attack 16 courses.

It covers the basic subjects of mathematics, a sub-course of mathematics, reference subjects, general courses and general learning tools.

When Cheng Nuo first arrived at the Mathematics Department of Peking University, he once asked Cai Yuanpei the reason for arranging these subjects, and the other party's original words were:

"The programme focuses on both basic and specialist training, so that students can continue to pursue a better degree or work directly after graduation."

It is precisely because of this characteristic that Cheng Nuo's determination to deepen the exchange and cooperation between the aviation school and Peking University has deepened.

Raising his hand, Cheng Nuo called the guy on the side: "Master, do you have any good snacks?"

When the guy heard this, he hurriedly trotted over and smiled with a smile on his face: "This master, you can ask the right person, the common eight pieces such as chicken fat cakes, roll cakes, mung bean cakes, etc., that is, if you want to eat milk skin cakes, peach cakes, dried vegetable moon cakes, I can find them with you."

Hu Shile was happy, and said curiously: "There are also masters in the back kitchen of our teahouse who will do this?"

The guy smiled: "Look at what you said, our restaurant sells tea, how can there be any master who specializes in making tea for people." Dim Sum, I bought it for you on errands, as long as you give enough money, the dim sum in the palace can come with you."

Cheng Nuo became interested: "In other words, master, can you still run around the palace and come out again?"

Seeing that the tea guest was serious, he seemed to really have this kind of thought, and when he looked around and saw that no one was paying attention, he whispered: "Just tell you, as long as you give enough, the water tank in the palace can carry it with you, as for what way to pass, we have our own tricks."

"Don't, what do I want that thing for, it's still occupying space, when the gossip coalition army came, it would have scraped the gold paint on it a long time ago, and it would have been worthless for a long time." Seeing that the guy was going to take the joke seriously, Cheng Nuo hurriedly came out and braked: "Let's honestly eat something that can be digested."

As he spoke, he gave the guy some change and asked him to buy snacks first, and the rest as errand fees.

Seeing the guy running out happily, Cai Yuanpei took a sip of tea and put down the teacup: "As the saying goes, no merit is not lost, let's just come out for a cup of tea, and by the way, let the two of you young people get to know each other, you don't need to engage in such a big battle, right?"

Hu Shi also said politely: "Yes, Professor Cheng, you also said just now, you have already had dinner when you come out, and it may be a bit wasteful to buy so many dim sum."

Cheng Nuo smiled: "It's okay, it's just that there are more tricks ordered, and in fact, it's just the same thing when you eat it in your stomach." Besides, according to the Western tradition, we can call this an after-dinner snack, which happens to be in line with our school system reform."

Cai Yuanpei shook his head helplessly: "Anyway, it's not us who spends money, you can do it yourself." But we can't eat much, it just so happens that you have a lot of children, so when you leave, just pack it up and take it back to your own house."

Cheng Nuo didn't answer in a hurry, got up with a smile and poured tea for Cai Yuanpei, and even walked directly behind him to pinch his shoulder.

This diligence made Cai Yuanpei a little unbearable, and waved his hand again and again: "Stop, stop, your hand strength is not small, if you pinch it again, I will have to let you break up this old bone."

Cheng Nuo smiled and said, "Then my strength is lighter, Cai Gong, do you think this strength is good?"

As he spoke, the strength in his hand became a little less.

However, Cai Yuanpei didn't want this, and directly grabbed the other party's hand: "I mean, you don't need to pinch it anymore, you could have lived to the ancient rare, you have to at least get the sixtieth nail in these two strokes."

Unexpectedly, Cheng Nuo still didn't give up, and continued to squeeze his shoulder with his other hand: "Cai Gong, please wait a little longer, I have to pinch it back for you in the past ten years."

"...... you" Cai Yuanpei suddenly laughed angrily, turned around and pointed with his index finger for a long time, but he didn't know what to say, and finally had to say helplessly: "It stands to reason that the aviation school was created by your academy of sciences

There is no shortage of highly educated talents, so why does it depend on our Peking University?"

Hu Shi lifted his glasses, also puzzled: "When it comes to high-tech technology, we are not good at it. Moreover, in this era of war and chaos, it is not easy to make some money, why did Professor Cheng go to build an aviation school, the cost is huge.

In my opinion, the only difference between this and throwing it in the water is that the money is thrown in the sky, and the wind blows it all away."

Hearing this, the smile on Cheng Nuo's face gradually dissipated: "Then according to Dr. Hu's opinion, what should we do?"

Hu Shi didn't think about it, so he blurted out: "Simple, since others have it, we buy it, pilot training can be used as a bargaining chip in business negotiations, we pay for the plane, and they help train people."

Cheng Nuo stopped what he was doing and said seriously, "In other words, to use the purchase of weapons to promote the reform of domestic military development?"

Hu Shi thought for a moment and said confidently: "Just like my teacher Dewey's motherland, the United States, the current Britain, France and other countries buy weapons and equipment from them, and it will not affect these countries to gradually grasp the initiative in the European war.

Of course, it can also be understood as exchanging the market for technology, market behavior, and everyone has to make money."

Yes, it's no wonder it's better to buy than to build, all the big things are imported, and there is a lot of rent-seeking space hidden in it, and the people on the line are full, but it's a pity that the officers and soldiers on the front line are suffering.

Cheng Nuo secretly spat in his heart and said unceremoniously: "The arms trade can only solve the contradiction between "have" and "have", and cannot fundamentally bring about the qualitative progress of national defense technology. In the international political struggle, national defense technology is a very important and sensitive field related to national security.

We cannot buy some cutting-edge national defense science and technology, and it is fundamentally unrealistic to imagine that a military revolution will be achieved through foreign imports. Even if it can be bought, it will either be a foreign obsolete technology, or a second- or third-rate technology."

Hu Shi did not give up: "What if we can really introduce advanced technology from abroad?"

Cheng Nuoyang raised his eyebrows and sneered: "Without the accumulation and iteration of technology, even if there is the most advanced technology, can we understand and learn? In the future, high-precision and sophisticated technical equipment, whether civilian or military, will move closer to the direction of system integration, and the possibility of imitation production will be greatly reduced."

Hu Shi originally knew nothing about industrial technology, and he was dumbfounded when he went down with this combination of punches.

I opened my mouth to say something, but I didn't know what to say, so in order to hide my embarrassment, I had to pick up the teacup again and drink water.

Cai Yuanpei stood up at the right time, tilted half of his body sideways and asked, "In the final analysis, the main purpose of your aviation school is national defense?"

Cheng Nuo nodded and returned to his position: "At present, a country must maintain both a separate civilian industry and a separate national defense industry, and the civilian industry and the military industry are separate and self-contained, and the country's financial resources will definitely be unbearable in the long run."

Pouring himself a cup of tea, Cheng Nuo laughed at himself again: "Of course, we, as a public family, can't pin all our hopes on them, and running an aviation school is also a last resort."

Hu Shi on the side nodded: "Professor Cheng, I understand your original intention."

Cheng Nuo just didn't feel good about Hu Shi, there was no need to be very enmity with him, so he poured a cup of tea for the other party and smiled: "It's not something that can be done by one person, and you still need everyone's help."

Generally, teahouses don't like tea customers to talk about political affairs, but Sijiu City is so big, and many people live in a small area all their lives.

In addition, most of the people who come to the teahouse to drink tea are men, whether they are upper-class people or low-level people, regardless of whether they are right or not, they always like to express their opinions on national events, and the topic is still led to the recent national events of the country.

Originally, they all talked about their own things, who would have thought that Cheng Nuo and the others were talking about the topic too vigorously, and before they knew it, a group of people were already around them, listening to them talk about these contents with their ears pricked up.

Even the grandfather and grandson who were pulling the erhu on the side stopped their work and followed the crowd to look this way.

"Grandpa, what do you mean by an airplane?" grandson

Holding his fingers in the corners of his mouth, he curiously pulled the corners of his grandfather's clothes.

"Kite remember? It's a big kite that doesn't use a kite string, but the difference is that people can sit on the plane." After traveling south and north for half his life, grandpa is obviously very experienced.

"Wouldn't the plane have fallen without a kite string?" Sun Tzu continued.

"Well, this is what these gentlemen are capable of, remember to study hard when you go to school in the future, and worship these gentlemen as soon as possible." Grandpa kindly touched his grandson's little head.

……

Through the corner of his eye, Cheng Nuo roughly saw the surrounding situation.

He then stood up and deliberately raised his voice and said, "How to become a qualified military strategist, first of all, to understand how great the economic potential of the country is, and the country must live first, and then arm.

Otherwise, it would be tantamount to stuffing a dead man into a heavy suit of armor, even if the armor was made of the hardest steel, it would not do that to that person."

An unknown tea guest who knew a little bit about the door asked loudly, "Everyone can talk about the truth, but can you give a solution?"

At this time, Cai and Hu noticed that there were already a bunch of tea customers watching the excitement around the three circles and three circles outside.

Taking in everyone's expressions, the two of them were not only surprised, but also looked forward to Cheng Nuo's next step.

And Cheng Nuo really lived up to expectations, squinting his eyes and smiling, "I do have a way here."

"Shall you tell me quickly?" The anxious tea guest asked.

Cheng Nuo deliberately whetted their appetites, and took a sip of tea before slowly saying, "In official terms, it is the integration of the army and the people, and the army and the people. In national defense construction, we have always implemented the principle of combining production, education and research to transform national defense technology into civilian use and promote economic development."

"And what are the effects of such a strategy?" Looking around, Cheng Nuo smiled and said, "It can not only save national defense spending, but also promote the purpose of military revolution and technological development and economic development.

In fact, to put it bluntly, it means that with the right strategy, you can spend one share of money and do two jobs."

Here, the reason why Cheng Nuo repeated what he said before is to convey this path of future development of the Academy of Sciences to more people through the mouths of the people.

There may not be many people who are serious at the moment, but in the future, when the development results of the Academy of Sciences benefit more people, recalling this sentence will greatly enhance its influence.

Moreover, in this regard, the United States in later generations benefited from this policy, constantly ushering in new breakthroughs in high and new technology, and feeding back military progress.

Among them, the United States established the "National Defense Technology Transition Commission" in the 90s, which became a special guidance and coordination body for the implementation of military-civilian integration reform. We should open up the market for military technology, implement the practice of civilian use, apply military technology to civilian use to the greatest extent, and raise the level of generalization of military and civilian product standards.

Among them, in the design and production of major weapons, a large number of low-cost dual-use parts and components have been used, the most classic is the Yin Lak War, the US military purchased as much as 25 billion US dollars in Silicon Valley civilian products.

[At present, it is the most complete and best app for listening to books, integrating 4 major speech synthesis engines, over 100 kinds of timbres, and it supports offline reading

But right now I'm still worried about one thing."

Youheel took the initiative to stand up and asked, "What can still stump you, come out and see if the big job can give you a trick?"

Cheng Nuo gave the person a look of approval, and then said: "Right now, the students are on demand, as long as they graduate from middle school and are in good health, they can come to our aviation school to study, and they will eat and live in the middle bag, and they will definitely not charge you a penny, even ah......

"Or even what?"

"I will even cooperate with Peking University and get a graduation certificate from Peking University at the same time in the future!"

Regardless of how bad the reputation of Peking University was, he is also the No. 1 national university in China, and now Cai Yuanpei is the president, and the gold content will only get higher and higher in the future.

Those with sharp eyes saw Cai Yuanpei at the same table, thinking that this would be more secure.

One to ten, ten to hundred.

The crowd was like boiling water, boiling in an instant.

They all shouted to ask about the specific admission conditions, Cheng Nuo smiled and said, "Don't worry, we will post the things at the new site of the Academy of Sciences when the time comes, and everyone is welcome to come and see them then."

In this way, Cheng Nuo answered questions while persuading everyone to leave.

Unexpectedly, Chinese have always liked to watch the excitement, and there are not only fewer people, but more and more.

In the end, I had to find a reason, and after agreeing on the destination with Cai and Hu, I left separately.

Before leaving, Cai Yuanpei also specially explained: "Don't forget, there are so many talents in your Academy of Sciences, why did you pull us to Peking University?

You've done it first, and I've done it after the fall!"
