Some academicians who are prestigious in the eyes of students but infamous in academic circles. Ironically, everyone knows that this person can't do it, but he was voted as an academician because people can play interpersonal relationships. And generations of students have been ruined by such academicians because of academic freedom. In a word, the prospect is optimistic, but we should face up to the shortcomings and not always take the national conditions as a cover. People who engage in scientific research may wish to ask themselves: Why engage in scientific research? What is academic? Is the original intention of doing the problem for understanding or solving, or simply doing it, simply irrigation? It's time to say this sentence, "independent spirit, free thinking", plus perseverance, emotional intelligence and courage. Of course, with the increase of knowledge and experience, it is found that no matter the so-called masters at home or abroad, there are not many commendable achievements, mostly conservative and tinkering, which is called irrigation. In the field of mathematics, I gradually learned that there are not many really interesting things in PDE, and there are a lot of articles in the world. Therefore, I especially admire Zhang. To be a scholar, like Zhang, you should be humble, accumulate wealth, be a late bloomer, have a strong curiosity and have the courage to solve big problems. Drive scientific research with curiosity, look at the starry sky, walk in the present, understand mathematics, nature and life, and encourage yourself. Note: 1 I don't know other science and engineering subjects, but the average level of mathematicians in China is not low at all. It is a fact that there are few local talents, but it is really mainly a matter of time. The shortcomings mentioned above are not only in China, but also in the United States, and they are only in degree. The world is bustling, all for profit; Everything in the world is often for profit. Let's take a look at the successful experience of Jews, and those who are interested can learn about it. They respect both business and academics, so there is no contradiction between material and academics. Their success is not due to cleverness. A teacher who has been in the Jewish circle for a long time said that before the undergraduate course, Jews were far behind China. After the master's degree, Jews still lag far behind China. After the doctor graduated, the level gradually approached. A few years after the doctor graduated, everyone was similar. Then China people did a good thing, became famous and began to mix academics. Jews continue to concentrate on their studies. After 30, they accumulate a lot and live to be old. Seeing this question, there are still some answers that allude to one side of the transgenic debate. The topic of "Dungan" really has a far-reaching impact on Zhihu. Then I'll bring some contraband. It is wrong for laymen to evaluate experts, no matter whether this statement is right or wrong. I am embarrassed to say that the level of many experts is really not so good, not academic. It is normal for people to have different talents, and the experience of the day after tomorrow is different. The level mentioned here is the attitude and grade of learning, and it has nothing to do with wholeheartedly learning. Learning utility is understandable. Take some technical terms that are very simple in nature, it is also a personality. I don't care about this. But it is no wonder that even laymen look down on them, because they have no conscience, brazenly deceive laymen, and even forge and misinterpret data. Personally, I don't think anti-intellectualism is the root cause, but some people do have problems with both ability and political integrity.
