Shen Qi left CUHK and went home, and immediately revised his thesis when he got home.

The revision work was completed quickly, and Shen Qi checked it again, and there was nothing wrong.

"Oh, by the way, as is customary in academic circles, I have to add organizational unit information. Shen Qi's gaze returned to the first page of the paper.

There is a standard format for journal papers, and the standard format for the first page is as follows (example):

"On the Application of General Relativity in a Certain Field" (thesis title, no more than 20 words)

Lao Wang (author's name)

(School of Physics, Tsinghua University, Capital 100000, China) --- parentheses must be used here, and the information such as the author's affiliation, address, zip code, etc., must be filled in the parentheses. Authors who do not have an organizational unit and do not have a permanent residence do not need to write this information.

Then below are the abstract and keywords.

Shen Qi's paper completely uses the standard format, except for the information in parentheses below the author's name on the first page, which is not written, and he has concerns about submitting it for the first time.

But the editor of the big sword said, try to complete the information as much as possible, high school students are high school students, what are you afraid of.

So Shen Qi operated the computer keyboard, typed and completed the organizational unit, address, zip code and other information under the author's name on the first page of his paper:

(Nangang No.2 Middle School, Nangang City, Nangang 510000, China)

The title of Shen Qi's dissertation is "Some New Solutions for Linear Nonhomogeneous Differential Equations with Second-Order Constant Coefficients", which is no more and no less, just 20 words.

The title of the first edition of the paper was 19 words, and after adopting the professional advice of the editors of Dabaojian, Shen Qi added a "new" word, and the title of the paper reached the upper limit of 20 words, which did not exceed the standard.

In fact, the title of the paper is similar to the title of the book, the shorter the number of words, the easier it is for readers to remember, but the title "Differential Equations" has been occupied by Leibniz and Bernoulli brothers three hundred years ago, and Shen Qi can only lengthen the number of words.

Last month, Shen Qi asked his father to apply for academic funds and bought a printer, which was connected to the computer at home.

Print out the paper version of the paper, Shen Qi took it to the express delivery point outside the community to send it to the express, and submitted the paper to the editorial department of the "Mathematical Innovation News" again in a formal way. This time, there is a big sword editor to do the internal response, and it is just a process to go through, and it is only a matter of time before it is published.

On the road of advanced mathematics, Shen Qi made great strides, but in the field of elementary mathematics, he encountered obstacles.

More than a month has passed, and the "High School Math Problem Solving Skills Guide" promised to the classmates has not yet been completed, which is not easy to get and much more difficult than writing professional papers.

With this major academic topic in mind, Shen Qi set off for the capital again at the end of October to participate in the Golden Autumn Camp of Peking University as planned.

This Peking University Golden Autumn Camp gathered hundreds of outstanding high school graduates from all over the country, who have their own strengths, or are proficient in mathematics, or good at physics, or have won awards in biochemistry.

or write a good article, or play a good song, or say that cross talk can host...... All in all, the Eight Immortals have their own magical powers, and they are the best group of young people in this age group.

Peking University is strong in arts and sciences, and has contributed 79 academicians of the Chinese Academy of Sciences and 19 academicians of the Chinese Academy of Engineering to the country.

The number of academicians of the Chinese Academy of Sciences at Peking University far exceeds that of the academicians of the Academy of Engineering, and it can be seen from this data that Peking University is strong in theory and weak in application. Of course, this "weakness" is relative to the university in Zhongguancun next door.

It is a good choice for students studying literature and science to study at Peking University, and Shen Qi, under the leadership of the teacher of the Golden Autumn Camp, visited Peking University with other students, which was their first lesson after entering the camp.

"Peking University can, there are so many famous alumni. Shen Qi lingered on the campus of Peking University and was impressed by the profound cultural heritage of this century-old university.

In front of the Russian building on the shore of the unnamed lake, surrounded by green grass and cypresses, the bronze bust of Mr. Li Dazhao stands here, he is amiable and righteous and awe-inspiring, he looks at the crowd of people in front of him, the new cultural movement does not seem to be over, he has not been able to witness the fruits of the victory of the revolution, and there is a little regret embedded in his eyes.

Li Dazhao's comrade-in-arms Mr. Cai Yuanpei gazed at the sky not far away, this bronze statue carved lifelike, Mr. Cai Yuanpei looked solemn and worried about the country and the people, he witnessed the victory of the revolution, but the national mission of expelling the Japanese invaders made him dare not slack off.

Mr. Jin Qiuying took the students to review the history of Peking University, and also introduced some well-known alumni of the present generation, who are all big names in academia, literature and art, business and even politics.

"Cow, our Peking University is really good. Shen Qi quickly entered the state, and "Peking University can" was upgraded to "Our Peking University is really good", and in this kind of environmental atmosphere, the spirit of ownership came into being.

Finally, the large army came to a rock.

The stone rests inconspicuously in the lawn, half a meter high, ordinary, no different from the kind of stone in the rockery in the park.

But Shen Qi fixed his eyes and saw that there was something strange about this unsightly stone.

The stone is engraved with small characters, "Peking University Tsinghua University, evergreen friendship".

"This stone was sent by Tsinghua University on the 100th anniversary of the founding of Peking University. The teacher who led the team in the Golden Autumn Camp introduced such a simple sentence, and then led the team to leave, and walked towards the canteen to prepare for lunch.

"This ...... "Shen Qi's heart is cold, it's Tsinghua University, teacher, you have taken it lightly? Don't you tell me the small stories and tidbits in front of and behind the scenes of "Peking University Tsinghua Friendship Evergreen".

After lunch, the humanities education for the students was over, and the camp was disbanded and divided into several small camps.

Each small camp takes the discipline as the banner, and the students who are engaged in mathematics are divided into groups, and the students who are engaged in physics, chemistry, literature and history, and special talents are divided into a battalion.

Each professional camp is supervised by professional teachers from Peking University, and the trainees will receive a 20-day training, interspersed with some professional tests and comprehensive tests.

There are more than 20 students in the math camp, and there is only one way for them to enter the camp--- math competition.

There are many types of mathematics competitions, and Shen Qi takes the most high-end route, the champion of the National Finals of the Digital Federation and the IMO champion. He has signed a contract with Peking University and is scheduled to report to the Department of Mathematics of Peking University in September next year. The same is true for other trainees.

The nature of the Peking University Golden Autumn Camp is similar to the preparatory class, which is the educational stage between high school and undergraduate.

For students who are escorted, they don't have to take the college entrance examination, they play by themselves at home, and it is necessary to come to Peking University in advance to receive education, and it is necessary to maintain their enthusiasm for learning and the correct direction of study.

In the math camp, Shen Qi met an acquaintance, his teammate Zhou Yu'an of the Olympiad national team.

The two patted their shoulders and beat their chests, and greeted each other affectionately, they once won the IMO team championship together, but they were both brought by Peking University. Of the other four teammates from the national team, three went next door, and one chose to study abroad.

"Shen Qi, we haven't seen each other for a few months since we parted in London, what have you been busy with in the past few months?" asked Zhou Yu'an.

Shen Qi said: "I didn't have anything to do, I just wrote a math paper, what about you?"

"Awesome my brother, do you have any other hobbies besides studying?" Zhou Yu'an sighed, "Born in sorrow and died in peace, after I brought back the IMO team championship from the UK, the whole person's spirit suddenly relaxed, and I chased and played games at home every day, hey, I am already a waste dog, and I have forgotten how to solve even the simplest differential equations." If I don't come to Peking University for re-education, I may be terminated. ”

Shen Qi said heartbrokenly: "Zhou Yu'an, you are really a waste dog, you have forgotten how to solve the differential equations, and the national team is ashamed of you." Besides, I have a lot of hobbies, and you may not be able to beat me when playing games. What rank do you need me to fly with you?"

Zhou Yu'an said weakly: "Xingyao 2......"

Shen Qi became more and more heartbroken: "Spicy chicken, Cai Xingyao 2, I have already been the king." ”

He couldn't pass the math test, and the game rank was not as high as him, so Zhou Yu'an hurriedly changed the topic: "By the way, Shen Qi, what is the title of your math paper and where is it published?"

"Mathematical Innovation News", entitled "Some New Solutions for Linear Nonhomogeneous Differential Equations with Second-Order Constant Coefficients". ”

"it...... I forgot how to solve the differential equations, but you published them in professional journals. I worked hard to get to Star 2, but you easily became the king. Life is already so difficult, Shen Qi, why did you cause critical damage to me as soon as you met?"
