With the increase of study and experience, a person will naturally form a set of thinking mode on the basis of previous knowledge accumulation. The problems encountered will be filtered or tortured by this way of thinking, and new knowledge or information is no longer isolated, but quickly incorporated into the original knowledge reserve and integrated into it. In this way, a person's knowledge system can be formed and gradually expanded. The larger the knowledge system, the easier it is to incorporate new knowledge or information into it. Generally speaking, the more open and blue the original knowledge system is (the spectral sequence from blue to red defines the characteristics of knowledge from abstraction to intuition), the higher the efficiency of integrating relevant new knowledge. (But there are also opposite examples. 1965-1In the early 1990s, the author saw a domestic medical college graduate studying for a doctorate in laser physical chemistry in the United States, and he enjoyed it.
The problem is that the knowledge system formed unintentionally does not conform to a person's social role except for a long time. Take Mao Zedong and Chen Duxiu, who are talking about science online these two days. The former saved the day in the civil war and turned the Red Army from victory to victory. In the period of economic construction, we made mistakes again and again, even making bigger mistakes, in order to reverse the shake of leadership prestige and leadership position caused by previous mistakes. Before and after 1949, Chairman Mao's personal ability did not degenerate, and the difference of his leadership results came from the matching degree between his knowledge system and social role. Mao Zedong was the first expert of peasant movement in China. He deeply realized that peasants were the primary driving force of social change in China at that time, and armed separatist regime was the most suitable way for peasants to participate. During the period of economic construction, Chairman Mao was invited to visit the Soviet Union, and Stalin took the initiative to talk with him about 150 aid projects. Mao Zedong didn't know, so he sent a telegram to Zhou Enlai. Look at Chen Duxiu. As a scholar, Chen Duxiu studied Marx's historical materialism and predicted that China's transition from a feudal society to a more modern society could not be separated from the progress of the basic mode of production. However, its knowledge system lacks the understanding of farmers, who account for the vast majority of the population in China, and cannot understand and lead a social change with farmers' participation as the necessary condition. The marginalization of Chen Duxiu is inevitable. It can be seen how important it is to match the knowledge system with the social role.
Of course, our natural science graduate students don't necessarily have to shake the society like Mao Zedong and Chen Duxiu. Their diversified career choices can be future academic or technical leaders, experts or teachers with excellent skills or knowledge, successful entrepreneurs in the field of technical economy, patent lawyers with high winning rate, and administrative leaders who build institutional infrastructure for technical economy. Starting from the time of graduate students, consciously building a knowledge system according to their hobbies and career expectations will make the later growth more effective. With regard to the study of professional knowledge, the course concentration system of Harvard undergraduates provides a reference. The school takes out the courses of different disciplines, combines them and packages them into condensed ones for students to choose from. In this way, while keeping the course providers (departments and professors) relatively stable, they can easily adapt to social needs. The same is true for graduate students when building their own knowledge system: they should have their own career goals and problems to solve, and there is no disciplinary boundary.
The problem is the best teacher.
For graduate students whose future career is scientific research or technology development, the value of your work depends on the importance of the problems you want to solve and the ingenuity of the methods. Finding the important problem that you can solve is the first step. The clearer the problems in your mind, the stronger your awareness of building a knowledge system, and the higher your input-output efficiency. Therefore, when you enter a discipline and set foot in a field, it is extremely important to find and grasp those problems that have an important impact on the scientific discipline or economic field as soon as possible. Many graduate students in their early twenties are used to choosing research topics or fields to apply for in the next few years according to what they have studied or done. This is equivalent to using your high school intelligence level to choose the future. Twenty years old is the strongest learning stage in life. At this time, you should focus on the problems worth dealing with in the future, not just what you have learned.
Find fault with the shortcomings of the masters
Some inspirational books for young people often mention "standing on the shoulders of the master", but rarely explain how to climb on the shoulders of the master, rather than just standing on the instep. The idea that our team gives students is to pick up the shortcomings of the master and think about ways to improve it. If there are still important problems in a subject that have not been solved or explained, it must be that the masters in this field have not come up with a good solution. Or their previous work on these issues must have shortcomings and limitations. When a graduate student enters a subject and finds important issues of interest to him, it is easy to know who is the leading academic leader. Reading their latest masterpieces and finding the problems they face are even helpless, which is a shortcut for you to climb onto the shoulders of the masters and have an ideological dialogue with them.
Practice interdisciplinary association.
Similarly, when there are still important problems in a discipline that have not been explained or solved so far, most of the internal methods or ideas in this field are powerless. At this time, the interdisciplinary association of "Kung Fu is beyond poetry" is likely to become the source of inspiration. You should always roam in your knowledge system with your topic, and completely ignore the disciplinary boundaries in roaming. If the knowledge system you build is broad enough relative to the problem you are facing, which contains the answer to the question, then your question is likely to encounter this answer in roaming. Even if your knowledge system is not so broad, roaming with questions will make your open mind effectively integrate with new knowledge and information and increase the chances of encountering questions and answers.
Get rid of worldly bondage and interference.
It goes without saying that unhealthy tendencies are rampant in China's academic circles. However, as a young graduate student, I hate it but I can't be influenced by it. Tutors who compete with their international counterparts for academic or technical commanding heights as ordinary professors in the domestic environment will face objective difficulties no less than students. Because China's science and technology evaluation mechanism and big project guide have not reserved living space for them, they have to participate in international competition for a long time with financial resources equivalent to competitors 1%-5%. The major scientific or technical problems in their minds constitute a unique peach blossom source; The practice of tackling key problems in science and technology all the year round has made it develop an attitude of calmly facing difficulties; In China, there is a reasonable balance between sufficient human resources for scientific research and development and unhealthy trends. This is maturity. As a graduate student, the essence of learning and training is actually to exchange academic maturity for your young courage and potential. Only by getting rid of unhealthy trends and the interference of current secular concepts can we get more valuable things. When the news of graduate students jumping off a building came from Beihou University again, I thought, when young people have the courage to hit the concrete floor with flesh and blood, will they realize the above discussion before jumping off a building, and will they have the pride and pleasure of living to see it?
