Go back to the past and be a schoolboy

As the first school in China to carry out university mathematics curriculum planning, as early as the early years of the Republic of China, only Peking University established mathematics.

Its courses mainly include differential calculus, differential equations, function theory, modern mathematics, calculus of variations...mathematical exercises, astrology, etc. 16 courses.

It covers basic subjects of mathematics, subjects of a certain branch of mathematics, reference subjects, general subjects and general learning tool subjects.

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

"This plan focuses on both basic training and specialized training. After completing these subjects, students can either continue to study for a better degree or work directly after graduation, achieving the same effect."

It was precisely because of this characteristic that Cheng Nuo's determination to deepen exchanges and cooperation between the aviation school and Peking University was further strengthened.

Raising his hand, Cheng Nuo called over to the guy beside him: "Master, do you have any good snacks here?"

Hearing this, the man hurried over with a big smile on his face: "My lord, you are right to ask the right person. The eight common items such as chicken oil pancakes, crispy rolls, mung bean cakes, etc., are the milk pancakes you want to eat." , peach crisps, and dried vegetable mooncakes, I can find them with you."

Hu Shi was amused, and asked curiously: "Is there a master chef in the back kitchen of our teahouse who can make this?"

The buddy smiled: "Look at what you said, there is no master chef who specializes in making tea for people who sell tea in our restaurant. I will run errands for you to buy dim sum. As long as you give enough money, the ones in the palace will Snacks can also follow you."

Cheng Nuo became interested: "That is to say, master, can you still go to the palace for a while before coming out?"

Seeing that the tea guest was serious, it seemed that he really had this idea, and when he looked around and no one was paying attention, he said in a low voice: "Let me tell you this, as long as you give enough, the water tanks in the palace can be carried by you. As for the way to go, we have our own tricks."

"No, what do I want that thing for? It's still taking up space. When the gossip coalition forces came over, they had already scraped off the gold paint on it, and it was already worthless." Seeing that the guy was about to make a joke Seriously, Cheng Nuo hurried out to brake: "Let's eat something we can digest honestly."

As he said that, he gave the man some change and told him to buy some snacks first, and the rest would be used as errand expenses.

Seeing the waiter running out happily, Cai Yuanpei took a sip of tea and put down the teacup: "As the saying goes, you don't get rewarded for nothing, we just came out for a cup of tea, and let you two young people get to know each other by the way, there is no need to do this A big battle, right?"

Hu Shi followed suit and said politely: "Yes, Professor Cheng, you just said that you have already had dinner when you came out, and it might be a waste to buy so many dim sum."

Cheng Nuo smiled and said, "It's okay, it's just that I ordered more varieties. In fact, it's just the same thing when I eat it in my stomach. Besides, according to the Western tradition, this can be called after-dinner snacks, which coincides with the reform of our school system. "

Cai Yuanpei shook his head helplessly: "Anyway, it's not us spending money, so you can figure it out. But the two of us can't eat too much. It happens that your family has a lot of children. When you leave, just pack it up and take it back to your own home."

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

Cai Yuanpei couldn't stand this kindness, he waved his hands again and again: "Stop, stop, your hands are strong, if you keep pinching my old bones, you will break them."

Cheng Nuo laughed and said, "Then I'll use my strength lightly. Mr. Cai, do you think this strength is okay?"

As he said that, the strength in his hand became slightly weaker.

However, this is not what Cai Yuanpei wanted, and he directly grabbed the opponent's hand: "I mean, don't pinch it anymore, you can live to the seventies, you have to get sixty at least in these two strokes."

Unexpectedly, Cheng Nuo still didn't give up, and continued to pinch his shoulder with the other hand: "Mr. Cai, please wait a little longer. No matter how hard you work in the past ten years, I have to squeeze it back for you."

"You..." Cai Yuanpei laughed angrily, turned around and pointed with his index finger for a long time, but didn't know what to say, and finally had no choice but to say: "Accordingly, the aviation school was founded by your Academy of Sciences, and there is no shortage of highly educated talents. Why do you rely on our Peking University?"

Hu Shi adjusted his glasses, but also puzzled: "We are not good at high-tech when it comes to it. Besides, in this era of war and chaos, it is not easy to earn some money. Why does Professor Cheng want to build an aviation school? The cost is so high." 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 faded: "Then according to Dr. Hu's opinion, what should we do?"

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

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

Hu Shi thought for a while, and said to himself: "Just like my teacher Dewey's motherland, the United States, Britain, France and other countries now buy weapons and equipment from them, and it doesn't affect these countries gradually taking the initiative in the European war.

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

Yes, no wonder it’s better to buy than to make. All the big things are imported, and there is a lot of rent-seeking space hidden inside. People in the first line are full, but it’s a pity that the officers and soldiers on the front line suffer.

Cheng Nuo spat secretly in his heart, and said bluntly: "Arms trade can only solve the contradiction between 'have' and 'have', but cannot fundamentally bring about qualitative progress in defense technology. In international political struggles, National defense technology is related to national security and is a very important and sensitive field.

We cannot buy some cutting-edge defense technologies, and it is simply unrealistic to dream of realizing military revolution through foreign imports.Even if it can be bought, it is either a technology eliminated by foreign countries, or a second- or third-rate technology. "

Hu Shi didn't give up: "What if we can really introduce advanced foreign technology?"

Cheng Nuoyang raised his eyebrows and said sarcastically: "Lack of technical accumulation and iteration, even if we have the most advanced technology, can we understand and learn it? Future high-tech equipment, whether it is civilian or military, will be integrated into the system The direction of the approach is closer, and the possibility of imitation production will be greatly reduced."

Hu Shi didn't know much about industrial technology, but after this combination of punches, he was beaten speechless.

He opened his mouth to say something, but he didn't know what to say. In order to hide his embarrassment, he had to pick up the teacup and drink water again.

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

Cheng Nuo nodded and returned to his seat: "As far as the current situation is concerned, a country must maintain a separate civilian industry and a separate defense industry. The civilian industry and the military industry are separate systems. In the long run, the country's financial resources will definitely not be able to bear it."

After pouring himself a cup of tea, Cheng Nuo laughed at himself, "Of course, as a public family, we can't place all our hopes on them, and we have to do it as a last resort to set up an aviation school."

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

Cheng Nuo just had no feelings for Hu Shi, and there was no need to make enemies with him, so he poured a cup of tea for him and said with a smile, "It cannot be done by one person, and we need everyone's help."

Generally, teahouses don't like tea guests to talk about political affairs, but Sijiucheng is so big, and many people live in a small area all their lives, so it's boring to talk about it after a while.

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 affairs, and the topic is still brought to the recent national affairs of the country.

Originally, they all talked their own way. Who would have thought that Cheng Nuo and the others were talking about such a hot topic, and before they knew it, there was a group of people around them, listening to them with their ears pricked up.

Even the grandpa and grandson, who were playing the erhu, stopped their work and followed the crowd to look this way.

"Grandpa, what is an airplane?" The grandson put his finger in the corner of his mouth and curiously tugged at the corner of Grandpa's clothes.

"Do you remember the kite? It's a big kite that doesn't use kite strings. The difference is that people can sit on it." Grandpa obviously has a lot of experience traveling all over his life.

"Then without the kite string, wouldn't the plane fall down?" Sun Tzu continued to ask.

"Here, this is what these gentlemen are capable of. When you go to school, remember to study hard and join these gentlemen as soon as possible." The grandfather stroked his grandson's little head kindly.

……

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

Then he stood up and deliberately raised his voice and said: "How to become a qualified military strategist, you first need to understand the country's economic potential, the country must first live, and then arm.

To do otherwise would be the same as cramming a dead man into a suit of heavy armor, even if the armor were made of the hardest steel, it would do no good to that man. "

An unknown tea drinker who knew a little bit asked loudly: "Anyone can explain the truth, but can you give a solution?"

Only then did Cai and Hu notice that there were already a bunch of tea-watchers surrounded by three circles inside and three circles outside. No matter whether you can understand or not, write down the words first, so that you can continue to talk nonsense with your friends later. .

Looking at everyone's expressions, apart from being surprised, the two of them were also looking forward to Cheng Nuo's next step.

As expected, Cheng Nuo lived up to expectations, squinting his eyes and smiling, "I do have a solution here."

"Then are you going to tell me quickly?" asked the impatient tea guest.

Cheng Nuo deliberately whetted their appetite, took a sip of tea and said slowly: "In official terms, it means integrating the army with the people and integrating the army and the people. National defense construction has always implemented the policy of combining industry, education and research, and transformed national defense technology into Civilian use to promote economic development."

"Then what is the effect of such a strategy?" Looking around, Cheng Nuo smiled and said, "It can not only save defense costs, but also promote military revolution, technological development, and economic development.

In fact, to put it bluntly, it means that if the strategy is right, you can spend the same money and do two jobs. "

The reason why Cheng Nuo repeated what he said earlier is to pass on the future development path of the Academy of Sciences to more people through the mouths of the people.

Maybe not many people are serious right now, but after more people benefit from the development achievements of the Academy of Sciences in the future, recalling this sentence will greatly increase its influence.

And on this point, the United States of later generations has benefited from this policy, constantly ushering in new breakthroughs in high-tech, 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 organization for the implementation of military-civilian integration reform.Open up the market for military technology, transfer military technology to civilian use, maximize the use of military technology for civilian use, and improve the generalization of military and civilian product standards.

Among them, in the design and production of major weapons, a large number of low-cost military and civilian components have been used. The most classic example is that during the Iraq War, the U.S. military purchased civilian products in Silicon Valley as high as 250 billion US dollars.

Of course, this is not all good, and exaggerated events such as a $600 ashtray, a $1200 coffee cup, and a $1280 teapot are also common.

However, in this era, what Cheng Nuo wanted to do more was to use the power of the Academy of Sciences to cooperate with the public to achieve the goal of consolidating national defense.

This time, whether it is the aviation school or the lecture in the teahouse, it is just a means of his propaganda.

In this way, Cheng Nuo later expressed the concept that national defense and economic construction complement each other through some easy-to-understand words. Whether it is an adult or a child, everyone will gain more or less from listening to it.

In the end, amidst the applause of the whole hall, Cheng Nuo bowed his hands and said politely: "Men, the affairs of the aviation school have already been settled, and there are arrangements for money, land, and planes, but right now I'm still paying attention." Worry about one thing."

Some fans stood up and asked: "What can still trouble you, tell me and see if Dahuo can give you a trick?"

Cheng Nuo gave the person an approving look, and then said: "We are short of students right now, as long as you graduate from middle school and are in good health, you can come to our aviation school to study, with food and lodging included in the middle, and you will definitely not charge a penny Yours, even..."

"What even?"

"We will even cooperate with Peking University and get a diploma from Peking University at the same time in the future!"

Don't care how bad Peking University's reputation was before, but it is also the number one national university in China, and Cai Yuanpei is still the president, and its gold content will only increase in the future.

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

One pass ten, ten pass a hundred.

The crowd is like boiling water, boiling instantly.

They all clamored to ask about the specific admission requirements, Cheng Nuo said with a smile: "Everyone, don't worry, we will post the stuff at the new location of the Academy of Sciences when the time comes, and everyone is welcome to come and see it."

Just like that, Cheng Nuo asked everyone to leave while answering the questions.

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

In the end, I had to find a reason. After agreeing on the destination with Cai and Hu, they separated and left.

Before leaving, Cai Yuanpei also deliberately explained: "Don't forget, there are so many talents in your Academy of Sciences, why did you choose our Peking University?
You can do it first and then play it, and I can do it too! "
