Author:Fudan University Time:2022.07.14

Editor's note: Since the start of the 2022 undergraduate "Graduate Star", since its launch, a group of outstanding undergraduate graduates have stood out. Self -strong hard work, serving dedication, scientific research reporting the country, comprehensive development, fighting against the epidemic ... They have worked forward and shining in their respective fields.

Recently, the list of "Star of Graduates" from Fudan University was officially released. The stars are bright, and the future can be expected. Today, let's get closer to the "Star of Graduates" from Fudan University -Hu Xingjian from the School of Mathematics.

Hu Xingjian

For Hu Xingjian, interest is definitely the best teacher.

In high school, he has participated in the Mathematics League many times and reads mathematics science books spontaneously in his spare school. Under the guidance of strong interest, he chose mathematics major after entering college.

After entering the Fudan Division, high -quality courses and perfect training systems have made him more and more loved by mathematics, and also become more firm on the road of exploration.

From the science popularization content in the hunting extracurricular book to the detailed theoretical framework of contact, and then to a more profound cutting -edge issue, Hu Xingjian was surprised to see his growth -not only became a "mathematical master", but also to discover mathematics because of love More possibilities, and passing the fun of mathematics to more people.

Diligent in thinking, not afraid of frustration, win prizes on the competition

In Hu Xingjian's eyes, mathematics is by no means abstract and boring.

"Whether it is a higher mathematical or linear algebra, these theories are developed in order to solve the problems in real life. Although the question seems to be exploring the theory, it must have such consciousness: I am solving the solution to solving Question, not doing theory, nor is it simply brushing the question. "

With such a mentality, after entering the university, Hu Xingjian opened his "practical verification theory" model. Four years of undergraduate, his most memorable time is the time in the fifth teaching building in the fifth teaching building. Although only one or two may be solved in the afternoon, he will try various solutions and compare them.

Not only that, Hu Xingjian often "does the opposite". "Many times we say" Against three ', it seems that the derivation of a typical example question is close to' universal '; but I will pay more attention to whether it can harvest other important knowledge in' one ', and think that it is impossible 'In the case, how to explore new solutions, "he said.

As the difficulty of the course continues to increase, Hu Xingjian's learning method is obvious. In the past four years, he has always maintained excellent results and has won all first -class scholarships in the school. However, on the road of competition, he encountered frustration.

In his sophomore year, Hu Xingjian participated in the National College Student Mathematics Competition for the first time and won the second prize of the Shanghai Division. This result is far from his expectations. Later, he participated in the National College Student Mathematical Modeling Competition, and found nothing. The results of the two competitions were unsatisfactory, which made him a bit low. "But during that time, it made me realize that it was a good thing to attach to mathematics, but it must not be‘ drilling the horns'. ”He said.

Hu Xingjian won the results in the math competition of Qiu Chengtong University

After adjusting the mentality, Hu Xingjian was no longer discouraged and continued to participate, but he valued the result. Kung Fu is worthy of the people. In the fall of 2020, Hu Xingjian entered one of the highest -level college mathematical mathematics competitions in the country, Qiu Chengtong College Mathematics Competition Finals. The results.

Go to the podium, approach classmates, the advanced path of "the great god of the digital hospital"

Hu Xingjian, who embarked on the podium

In Hu Xingjian's view, the achievements he have achieved cannot be separated from the discussion class.

As an important tradition of the development of President Su Buqing, the discussion class will ask each student to report, explain the derivation process of some exercises, and organize discussions. In this process, learn new knowledge, contact new areas, and discover and solve problems.

In the Mathematical Competition of Qiu Chengtong college students who won the silver medal, the final session asked the players to solve three problems independently and explained the practice of the questions to the judges within 15 minutes. "I have participated in a lot of discussion courses. Each report is more than 1 hour, and the expression ability is slowly exercised. Therefore, in the final lecture, there is no feeling of nervousness at all."

Hu Xingjian performed well in the "Class Academic Companion" activity

In addition, Hu Xingjian is also very grateful to the abundant extra -curricular knowledge learned in the discussion class, which not only allows him to grasp the in -depth assessment of highly difficult professional competitions, but also let him contact many cutting -edge issues. The research has laid a solid foundation, and also allowed Hu Xingjian to enter the group from a math man who "fight alone" and grow up with others.

In the "Top Talent Plan" of the Digital Institute, Hu Xingjian participated in the "Su Buqing Discussion Class" opened for undergraduates, involving Fourier analysis, partial micro -division equations and algebraic topology. Special discussion class. In the summer vacation of 2020, during the epidemic, Hu Xingjian also maintained a high frequency discussion rhythm a week after completing his research plan. In the process, he observed that there were some discussion classes because the number of participants was too small, and it was the reasons for many reasons for a semester. The students would be overwhelmed, exited halfway, or slowly not focused and not interested.

The discussion class organized by Hu Xingjian

As one of the few students who have always "adhered to" the discussion class, Hu Xingjian began to think about how to improve the theme and structure of the discussion class. In the winter and summer vacations, Hu Xingjian went to the podium as the host, and organized two discussions classes in an autonomous organization, with a total of 28 discussions. He took his classmates to learn the same topic, such as the same tone, general analysis, and statistical physics in the algebraic topology. The classmates who are determined to study in the field of mathematics have also been highly affirmed by the college teachers. In addition, Hu Xingjian is also committed to answering difficult questions in mathematical learning for the school students. He is an important member of the Volunteer Service Team of the "Great God of Channel". He has been in the team for 6 semesters and has accumulated over 150 hours.

"Actually, I heard this organization as soon as I entered the university! At that time, I was very interested. The helpless team asked the sophomore to join, and the professional performance must be excellent." Hu Xingjian quickly signed up after entering the sophomore and successfully passed the assessment to enter the team. From offline to online, he kept trying to explain mathematics problems in popular and concise language, so that more students understood mathematics, learn mathematics, and love mathematics.

To treat the classmates who came to ask questions, Hu Xingjian always responded with a high degree of patience and meticulous response. Even if he encountered very basic questions, he would sink down and explain it a little bit about the classmates- "I will observe the classmates. The degree of understanding, and then constantly reflect on and perfect the explanation method. If this method cannot understand the other party, then change one, and then change it. If you still can't understand it, then talk a few more times! I am happy to help the classmates. Divergent thinking. "

The colorful life beyond mathematics is more likely to explore youth

Swipe questions, talks, discuss problem solving ... Is there only mathematics in the life of mathematics? For Hu Xingjian, the answer is of course NO.

Hu Xingjian is the volleyball, basketball player of the college, and the second violinist of the Fudan University Symphony Orchestra. During the two concerts in the school, he also performed a wonderful collision between "mathematics" and "music". On the eve of the concert in May last year, because the performance track "Long March" only had the general spectrum for command, and there was no scores used by each instrument. Out of the branch of each instrument.

It is definitely a big project to identify more than 20 instruments from more than 700 complicated spectrums. If you write it one by one through the handwriting spectrum process, it will definitely be too late. Hu Xingjian was inspired by a sudden inspiration, thinking of helping the Python program to analyze the data structure of the pixel, identify the five -line spectrum, and then classify. "At that time, I was lying in front of the computer every night, and the two of my roommates ran more than 2 o'clock every day. Finally, I finally fought out before the first rehearsal." Hu Xingjian said.

Hu Xingjian assisted in the distribution of antigens within the building of the East District

Like many Fudan people, Hu Xingjian also strives to take responsibility for "unity, service, sacrifice" spirit. In April 2020, he participated in the "Goose Dream" project and was a high school student online for a high school student in Wuhan at the time of the epidemic area. During this year's epidemic seal, he devoted himself to the campus of the campus to participate in the virtual channel volunteer service in the Eastern District, and assisted in the issuance of antigen and materials and statistical testing in the building.

Today, Hu Xingjian has officially selected the Fudan "Zhuo Bo Plan" and will continue his studies in the direction of probability and mathematical statistics he is interested in, and study the process of Markov. He believes that this young field can help people understand random phenomena in life to a greater extent, and help people predict and decide in the fields of finance, artificial intelligence, biological statistics.

On the road of mathematics, Hu Xingjian has always moved forward. In the future academic career, he will continue to link personal learning with national needs and social reality. Society made the contribution of Fudan students! "Hu Xingjian said.
