I once wrote in my thoughts at the Academician Pei Gang’s forum that young people should be ambitious and should not be criticized, but this ambition should be to do things well rather than steal some benefits through heresy. and affordable. It is not shameful for a person to desire fame and fortune, but it would be ridiculous if he chooses the wrong path. Just like doing scientific research if you want to make money or become an official, it is a bit heretical, because doing scientific research can never guarantee generous rewards. If a person wants to make a fortune, I think it is best to do futures. People think I am ignorant when I say this. How risky are futures? But if you have the ambition to make money but don't have the courage to take risks, then you are talking nonsense. If you want to be an official, it is actually best to take the civil service exam. If you fail to pass the exam in one year, you can take the exam for two years. If you fail to pass the exam in two years, you can take the exam for three years until you pass. After all, civil servants are a brighter road than doing scientific research and then becoming an official. It is much less laborious to do this kind of curve to save the country. So why do you do scientific research? If, as Shi Yigong said, the purpose of doing scientific research is to appreciate the beauty of science, then it is estimated that less than 10% of scientific researchers can reach this level. This is also an overly ideal idea. As for the reason why I really want to pursue this career, apart from those gold diggers from China, Latin America, India, and Spain who want to use scientific research as a springboard in the United States, I think the most important thing is a kind of psychological feeling. Through scientific research, you can conduct meaningful thinking and logical judgment based on the knowledge you have learned, design scientific experiments based on the products of your creative thinking activities, and then perform the experiments yourself until the results appear. Such a process from knowledge to thinking to design to execution to realization takes into account people's various qualities and abilities and is a good exercise for anyone to perfect their character. Of course, scientific research not only subtly shapes scientific researchers, but the results of scientific research also reward those who are willing to devote themselves to him in a certain sense.
