The famous mathematician Chen Shengshen is studying, which is worth pondering, studying and learning. He emphasizes independent and active learning. When he was young, he wrote a poem "Kite", which is the embodiment of this independent spirit: "Kite, kite! I envy you holding high in the air; But why are you walking around uncomfortably? Is it because the breeze blows on it and the hemp rope rolls below, so I can't rise to it and fall to Pingyang, and I pity you! Why isn't this free? It turns out that you have no automatic ability, so you are so upset. " He has the habit of reading books, that is, he takes the initiative to find books to read. He read a lot of books. I especially like reading miscellaneous books in the library. He said, "read whatever books you bring." I like reading history, literature, anecdotes and messy books. I often go to the stacks for hours, reading this, that and math books, but not just math books. I know some math books, some math magazines and some mathematicians. " Have a preliminary understanding of books, and you can find them when you need them later. He has a wide range of reading interests, not what to read according to the teacher's instructions, but what he likes to read according to his own interests. The second is to work hard at all. In the preface of Selected Works, Wu Wenjun said, "Teacher Chen also pointed out to us young people that to enter the door of modern mathematics, we should learn three books: Pontryagin's continuous group theory, Cherelli's Lie group theory and Weller's classic group theory". Mathematician Hou Zhenting also pointed out that reading three books and three papers well can take you to the forefront of scientific research. These books should be the most representative classics of this subject. It is a must-read for studying this subject and topic. You must study hard. Li Guangdi also said in the Notes of Rongcun: "To be a generation of managers, you must read an important book." It means not working hard at all and reading the most fundamental classics. Otherwise, if you read a lot of books and know a lot of things, you just don't understand the most fundamental and important thing, that is, the wrong use of kung fu. No matter whether you study math or engage in politics or other work, you have to work hard on important books. When studying a subject, Professor Chen Shengshen repeatedly stressed that he should not be afraid to find the "leader" of this subject and the best candidate in this field. I want to read his masterpiece. Third, study some materials that can be captured. During War of Resistance against Japanese Aggression's time, Chen worked in National Southwest Associated University. At that time, during the war, the conditions of books and equipment were very poor, let alone rich. But he used a lot of copies sent to him by Jiadang and studied hard. He said, "I have read at least 78% of the papers written by Jia Dang in my life, about 6,000 pages, and some of them are familiar." After studying these copies, he writes papers and publishes them in foreign magazines every year. At that time, Mr. Wang Li also used A Dream of Red Mansions to study phonology. It seems that when the conditions and equipment are poor, we can try to grasp some materials to study. The objective environment is almost the same, and appropriate research can be carried out. In a word, Professor Chen Shengshen is engaged in study and research. First, he actively reads miscellaneous books and looks for books, laying a broad foundation for his study. Second, read the representative works of the best people in this discipline and make in-depth research; Third, if objective conditions permit, grasp the existing materials and study endlessly.
