Li Laosan asked Cheng Nuo to sit firmly, and it didn't take long for him to pull him over in three steps and two steps.

After thanking Li Laosan, Cheng Nuo handed over the graduation certificate to the doorman, and the other party quickly took him to the office of Fan Yuanlian, the then director of education.

As a person who went to Japan to study at the end of the 19th century, Fan Yuanlian has a strong contribution to the development of modern higher education.

In her early years, she promoted the development of women's education, and in that feudal society where women were not talented and virtuous, she successfully led more than a dozen female students to study in Japan.

Later, he participated in the establishment of Jinmen Nanda University and Tsinghuatang University, and became the first president of Peking Normal University.

After getting the certificate of studying abroad, he only raised his eyebrows: "Harvard University in the United States of America, an amazing school, I have suffered a lot outside over the years, right?" ”

Cheng Nuo's attitude lowered and said modestly: "Compared with your construction in China, Mr., it is still far behind." ”

Fan Yuanlian was very satisfied with this gesture and applauded: "Okay, now the country is in ruins, and it is precisely the talent like you that is needed, and I welcome you back on behalf of all my colleagues in the Ministry of Education." ”

Cheng Nuo nodded: "I will definitely do my best to live up to what I have learned." ”

Immediately afterwards, Fan Yuanlian was very interested in Cheng Nuo's experience of studying in the United States, and the two chatted for a while.

When the two sides had almost finished talking, Fan Yuanlian took a sip of tea and said slowly: "Although you have the obligation to obey the assignment of the Minister of Education or the appointment of various ministries and academies, in fact, it is all voluntary. ”

"Zhiyuan, if you have any ideas, you might as well talk about it."

Zhiyuan is the word Cheng Nuo gave himself, which refers to the realization of ideals and ambitions.

"Sir, I just returned to China, and I don't know much about China, so I want to hear your opinion." Now it seems that Cheng Nuo has spent more time in the United States than in China in this life, and it is indeed unclear about the situation and it is difficult to draw conclusions.

Fan Yuanlian was not ambiguous, put the teacup on the table, and immediately said: "I have a place to go, I think it suits you very well." ”

"Sir, can you explain?"

"How much do you know about Peking University?" Fan Yuanlian paused, and then said: "Their new principal is none other than my old friend Cai Yuanpei, who is currently carrying out reforms with the support of the Ministry of Education, and is in urgent need of fresh blood to join, I think you are very suitable." ”

North?

This is something he could not have imagined in his previous life.

And it seems that he is still going to teach at Peking University, which is something that he would never dare to dream of, and even if he dreams it, he can immediately know that it is fake.

But now that the chief of education is personally endorsing it, it seems that he is not joking, and for a while, Cheng Nuo's head went down directly, and he didn't know how to reply.

At this time, another person walked outside the door, and took a closer look to see if it was not the middle-aged man I met in the shoe store just now.

I saw Fan Yuanlian greet him in person, and said with a smile: "Brother Xiaomin, it's really time for you to come, I just happened to find a great talent for you and Peking University!" ”

As he spoke, he was about to take Cheng Nuo's document and hand it to the middle-aged man.

"Zhiyuan, is it convenient for me to show your documents to the people?"

"Convenient." Cheng Nuo replied.

Taking advantage of the moment when the middle-aged man was reading the document, Fan Yuanlian pointed at him and introduced to Cheng Nuo: "This is Mr. Cai Yuanpei, President of Peking University, and the first director of education of our Ministry of Education. ”

Then he pointed to Cheng Nuo and said: "This is Cheng Zhiyuan, who came back from studying at Harvard University in the United States, has a very good resume, in addition to understanding professional knowledge, he has a deep understanding of society, humanity and the future, in my opinion, he is a great talent." ”

Here, Cai Yuanpei was still reading the document carefully, and echoed while reading: "Indeed, the exam results of every school year are among the best, and they are indeed very good." ”

"Well, if I'm not mistaken, your mathematics department of Peking University is still very lacking in backbones, and I think Zhiyuan's conditions are very suitable for your requirements."

Fan Yuanlian turned his head and said to Cheng Nuo: "There are many people with lofty ideals who are the same age as you in Peking University, and I believe that you will never be lonely if you go." ”

The mathematics major of Peking University started relatively late, opening the education department in 1913, and it was not until 1919 that it was changed from a department to a department, and the teaching staff was much different from other disciplines.

Therefore, Cai Yuanpei's demand for arithmetic talents is relatively large.

After reading the document, Cai Yuanpei also threw an olive branch to Cheng Nuo: "Zhiyuan, come to Peking University." ”

Since Cheng Nuo's crossing, all his actions have only had a vague direction.

That is to work hard and make this era better with personal strength.

However, when it comes to each step, it seems a bit vague, and the actual operability is not outstanding enough.

Being able to study in the United States as a Geng money is also stained with the light of education in his previous life, and later he found that the people around him are too powerful, he didn't dare to drop the chain for a moment, so he could only study hard and study hard, for fear that he would waste this precious study abroad quota because of himself.

I also chose arithmetic because I feel that mathematics is the mother of science, and it may not be the most correct, but it will certainly not be in the wrong direction.

But with the deepening of his studies, he became more and more extensive, and the future was still vague, so he chose to return to China first to look for the next direction.

At this moment, he suddenly realized that as a traverser, the biggest golden finger was the prophet of the unknown.

He knows better than anyone of his time the development of science in the world in the next century.

Proof of the Goldbach conjecture.

Turn the four-color conjecture into a four-color theorem.

Unravel the mystery of Fermat's theorem step by step.

......

In the process of scientific exploration, direction is a very important part.

And Cheng Nuo not only knows the direction, but also knows the result in advance.

Even if his talent is not as good as others, he also tries to use his foresight to reverse the situation.

In addition, he can also brush up his papers to build his reputation, become an academic leader himself, Poincaré is in Paris, France, and Hilbert is in Göttingen, Germany, and transfer the International Mathematics Center to China.

Under the right time window, what "DNA molecular double helix model", "penicillin", "nuclear magnetic resonance", "electronic computer", etc., too many science and technology can be realized.

The combination of education + industry and agriculture is his envisioned route.

With the super memory gained by crossing over, he clearly remembers that the books he read, such as "Celebrity Growth Stories", "The Childhood of Nobel Prize Winners", and "Twentieth Century Scientific Discoveries", were about to be turned over by him.

Even if a person's strength is limited, he can rely on his understanding of talents to gather big bulls and calves in advance to establish a scientific research team.

In this way, Cheng Nuo dared to envision the progress of basic science and feed back the development of industry.

With a good industrial base, we will be able to manufacture weapons with a larger caliber and longer range, and then the domestic war of resistance will not be so passive, and many martyrs will be spared sacrifice.

Mothers see their sons, wives see their husbands, and children see their fathers.

Dignity is only above the edge of the sword, and truth is only within the range of the cannon.
