Science itself is to solve theoretical problems, and we often can't predict the greater significance of a theory, which is why many scientists were not recognized by the world when they were alive, and their significance was not discovered until many years after their death. For example, the genetic law discovered by Mendel was not known until more than 30 years after its publication and 10 years after his death. At that time, only he saw its great significance, but the founder of genetics failed to think of the word gene, let alone genetic engineering. Another interesting example is Rolle's theorem in calculus of higher numbers. Rolle himself strongly opposes calculus. Even under the condition of academic freedom at that time, Raul's opposition to calculus had led to administrative intervention, but his research results had actually become an important cornerstone of calculus. Of course, this happened many years after 100, and the "Rolle theorem" was of course added by later generations. Non-Euclidean geometry became famous after Einstein used it as a tool of general relativity. The task of science is to seek truth, not its meaning. When everyone knows its significance, there is not much need for research-the position of the grandfather in this field has been occupied, and it is time for engineers to compete (of course, scientists and engineers can hold concurrent positions, and sometimes there is no obvious difference). This is why one of the important qualities of scientists is that they can stand loneliness. China's academic circles are impetuous now because they are too eager to find their own meaning or the meaning of their achievements, and even make up something to publicize their "meaning". If one day, China can have a large number of experts who only study the problem itself and ignore the "meaning", this country will be very lucky. In fact, for real scholars, the significance lies in the research process and the problem itself. Only in this way can we endure loneliness and deepen it, and only in this way can we avoid impetuousness and reduce fraud driven by utilitarianism. Of course, when the practical significance of the results appears, it should be vigorously promoted, but even if the researcher promotes it himself, he is more of a technician than a researcher.
