Metal materials bo four one. Frankly speaking, the undergraduate course is the initial adjustment of materials. I believe most people should be like this. Who can explain clearly what materials science and engineering are when filling in majors in the third and fourth tiers… Knowing something, wishful thinking that this thing can send rockets to the sky, make the train run more happily, and greatly benefit mankind. Thinking about it, I am a little excited. By the way, with the enthusiasm for realizing some self-worth, I read the literature conscientiously, and did experiments steadily. After turning to the blog, I once thought that I liked this all-encompassing subject very much, and even wrote anti-persuade posts. I never considered undergraduate from beginning to end. After the master’s degree, I look for a job directly. What kind of jokes are there? Now let’s look at this question again, slap her face. The current conclusion: from any consideration, there is no reservation to dismiss the materials (it is good to study a material undergraduate, and it is enough to have a perceptual understanding of the material world, I advise you to change careers quickly, the price is too low). In the field of traditional metal materials, I think I can do it well, and the article is more than enough to graduate. But in the last year, the closer I get to finding a job, the more I think I will be alive. In China, it is very likely that I will not be satisfied with scientific research and materials. For a long time, under the guidance of the article-oriented evaluation system, the field of materials has been highly saturated, and by the way it has completely deviated, becoming the ultimate cemetery of other science and engineering disciplines. In the end, the field of physics and chemistry will basically become the material. I don’t mention functional materials. I have been working on structural materials myself. The micron equiaxed crystals that most people know about n years ago are close to the mechanical performance limit within the practical range. With surface strengthening, it basically solves the problem. Most engineering application problems. As a result, all articles now focus on the pursuit of trade-off breaking, fancy nanoization, gradientization, and long-term hotness (irrigation) of amorphous high-entropy. These rather mysterious results have become the mainstream source of high-level journals, the main promotion tool for junior researchers, and they have squeezed most of the academic space. It is true that the current article is still the most fair evaluation standard, and there is no lack of creativity and inspiration in these results, but in the past two years I have completely lost the fun of reading the literature at the beginning. I am basically sure that most of the articles I read are of no practical value. It is said that we are studying materials of the 22nd century, and we simply cannot imagine the day when these results will be realized. The battery is similar in routine, but the impact factor has to be doubled, which is another problem. (Continued 1, September 2019) My TMD has just become Bo 5, and I will update it again. I don’t know if you understand it. At the beginning, there was no material specialty. Back then, it was called casting and forging welding, plus a heat treatment for deep-fried dough sticks. This kind of very honest WYSIWYG name will definitely not recruit any serious students in the 21st century, so it is all changed to materials majors. Of course, people’s rhetoric is to cover the non-organic, but I still firmly believe that this is to make students look better (some mechanics departments are renamed aerospace for the same reason). Later, my large materials continued to expand, rushing all the way in the direction of composite, energy, low-dimensional, and nanometers. At present, I am about to enter the quantum field, which is terrifying. I won’t mention it in the undergraduate course. There is basically no way to look at employment. What kind of school comes out and enters what kind of enterprise. Big metal steel mills dominate the manufacturing industry. Car companies are considered good, and interviews are basically not required. The common point must be that the local environment is poor. There are more options for master’s degree, and the salary is several thousand yuan higher. Most of them will change jobs within three years. Most of the ordinary doctors are looking for vacancies in each of the second or third schools. The Daniu family works in various first-line schools, and some of them go abroad to work. In short, no matter where you go, be obedient, petty bourgeoisie don’t have extravagant expectations. This point is actually the same on biochemical, environmental, machinery and civil engineering. Faintly pointing to a theory that struggle is useless… (Continued 2, May 2020) Yesterday (May 20) the defense passed (how can it be…), labor and management are finally going to graduate! Another year passed, and my thoughts changed a little. This epidemic made me think that the great empire is very promising. As long as the head is not crooked, the big socialist ship with Chinese characteristics can indeed ride the wind and waves. In the past year, I have been thinking more about materials major, including the treatment of master and doctoral degree and the choice of life path. My boss talked about one thing. After he was going to Europe in 1993 to do a Ph.D., the doctoral supervisor at the time advised him to stay at school. He showed the contract sent by the other party to the doctoral supervisor. The salary above was about 25,000 yuan. I let him go very happily. The boss’s Ph.D. advisor, as the top superalloy expert in China at the time, had a salary of only about 300 (orally not confirmed). This is the situation that year, and continuing to study has absolute cost-effectiveness in any aspect. Switching to my own personal experience now, both being a temporary worker, and counting the domestic social environment bonus, the absolute advantage of foreign post-doc salary has been nearly wiped out. In other words, in the current material field, there are few real shortcuts to advancement. Back to the material, the biggest feature of this school in the master stage is the low threshold. The current situation of the material itself is flooded, low practicality, scientific research only talks about the advantages without mentioning the defects, for students, the threshold is extremely low, all science and engineering, and even liberal arts can be transferred in (see music specialty students) Postgraduate entrance examination to materials). This, in turn, led to a very cheating result: it is difficult for students who learn materials to transfer out, and they have no stepping stone skills. The training program of materials science has been involved in all major fields of science and engineering, but it is basically a simple taste, only increased perceptual knowledge, and has not acquired any hard skills. It can be called “experienced” in engineering. In the field of social production with a high degree of division of labor, erudition has few tickets in most industries (the basics are extensive, and there may be some advantages in the later career). As far as the master’s degree is concerned, it is often only the few counterparts that the country-wide drawing is repeated. The above are all complaints, but if there are no accidents, I should have no chance or motivation to change careers. Because it was very illusory and hopeless, I found the fun of doing research again, to be precise, I found a sense of game, or a kind of cultivation. Although I still feel that what I have made is the material of the 22nd century, I will not complain about this anymore. The material provides a platform for creativity. Thinking of ideas, doing experiments, programming, and writing articles is just a kind of It’s just the way of work, and I really like this process, like a work of art. I don’t want to pretend to be 13, but I can’t help but say: Any kind of life definitely has gains and losses. Abandon all investment in those occupations or fields that seem to have a high rate of return, and let the work become a tool for making a living. As far as I can see, it will continue for 30 years. I suddenly feel that the future is not so worth looking forward to. From this point of view, from a long-term perspective, choose a direction that is not too bad and find a good tutor. At least for the Ph.D., I think it is very worthwhile, even if you are reading materials… (Continued 3, March 2021 20th) The friends I know have graduated and entered colleges or research institutes and started to live a life of fishing. Many of them have lain flat and gave up resistance. There is no graduation ceremony and no dinner. Online defense. I graduated quietly in June last year. I went abroad in August to experience a new part-time job life. I turned from a synchrotron radiation experimenter to a full-time rookie writing code and doing simulations, staring at one every day. Another deadline, the ups and downs of life are really exciting. Saying goodbye to my school days, I have been working for half a year, and I also started fishing. Let’s run a question today, let’s talk about what I have seen about the development of a doctor of material. The current overall feeling is: the wind direction is gradually changing, and going abroad may not be gold-plated, and there is a high probability that you will not be able to get contacts, but the domestic cattle group is rising, and the cost-effectiveness is getting higher and higher. The so-called cattle group are basically capable of producing large articles continuously and in batches. The boss is at the terminal of the field information flow. The idea has the first-mover advantage. The team also has the resources to train according to the model of manpower. When you are employed, there are disciples from all corners of the world. In contrast, individual research groups occasionally pile up something that can be written. It may be a little ironic that one of the main influences of Po Siwei on the rookie is that the backstage is becoming more and more important. It really means that you can do it or not. If you can’t, you can’t do it or not. The big boss’s hard push is still an out-and-out stepping stone. He sees no results and he enters the job, and he refuses to accept it. Fortunately, the current evaluation of professional titles still depends on the results, and the initial stage is mainly the paper. Although I’m basically sure I won’t change careers, I’m almost out of this area. I can’t see a project that can stabilize the top issue. I know I can’t make up five masterpieces in seven years, and I always think of it. Very lost. Finally, let’s talk about the typical. Some people around have already gone ashore or are destined to be easily pushed up. After careful consideration, these people have something in common: they are extremely active, and they are not pushed away by others, but lead others away (especially the boss). I really can’t find anything else in common, and there are counterexamples. Let’s start with the part of survivor deviation below, right for reference. Some people are very tolerant, stick to a difficult point (recognized as valuable) and can survive, with extremely clear goals (top issue), and will not start publishing articles until the fourth or even fifth year; some people have a particularly strong ability to seize opportunities , And luck, catching a car can drive Wuling Hongguang out of Lamborghini, and often change the car (I will give this man a capital suit when it is published); there is a comrade, from the beginning to the end, it will not make people feel It’s very powerful, but people can just publish good articles after a short period of time, and write a bunch of them step by step. Now it seems that they are basically not water. This kind of continuity is great, and the pace of scientific research is very stable; of course. , I have also encountered someone who can be called the “Three Views and Destroyed”, directly copying other people’s semi-finished products, copying the research group or even the nearby research group, and taking the last step first. The reputation is first come first served, and the reputation is infinite. There is no psychological burden, and he has his own set of survival logic. It’s too far off the topic, let’s talk about it later, let’s get a meal first.
