I wrote a lot of material mechanics, theoretical mechanics, fluid mechanics, and structural mechanics in four years of university. I really feel that the knowledge system is very old and has no real value, just like playing.
Maybe the hostility was a bit too harsh at the time. Now think about it, I really like mechanics, so I will go on the road of mechanics without hesitation. Regarding the subject of major, no matter what major you choose, you will encounter things you like or dislike. Dislike naturally feels meaningless. So, if you like it, go ahead, if you don’t like it, hurry up. When most people ask others for their opinions, they actually have an answer in their hearts. Just keep going along what you want. What is mechanical is not mechanical, it is best to be happy. But for me, mechanics is indeed a very useful and interesting subject. Maybe someone has a different opinion? Just keep the dispute. I have combined my experience on different occasions to preach and even comment on mechanics. Now I feel more and more that my level is not enough to reach a level that can easily evaluate the discipline of mechanics. So we still have to keep working hard. Liu Lixi: Freshman majoring in mechanics, how should engineering mechanics develop in the future? Www.zhihu.com In addition, in my daily life, apart from schoolmates, sisters, brothers and sisters, or classmates who met to do projects, there are still very few students majoring in mechanics. But from Zhihu, it is obvious that there are more and more groups of people who feel mechanics. This is a good phenomenon, but it always feels weird. Maybe I do agree that mechanics does not require many people to enter the pit? (Even I sometimes say that I am optical rather than mechanics. Of course, when I and other people complained, they told me that many evaluations of mechanics are not mechanics at all, but other majors. The mechanics course began to think that I understood mechanics, and even started to evaluate mechanics? But I think that the direction that can withstand the evaluation of other majors is a direction to be successfully applied and has a certain value. Forget it, the right and the wrong are free, here. At one point, everyone should be more mindful when making decisions. By the way, I will post the self-summary of teacher Xie Yushu in my undergraduate department in the teacher of Zitang. The kind of enthusiasm that is overflowing in the text is what I am always longing for. In addition, teacher Zhong Wanxie The story also gave me a lot of spiritual support. At that time, I might be in a bad condition, so I was watching Mr. Zhong’s recording and broadcasting class. The unremitting efforts of the older generation of mechanics workers than mechanics dissemination have a great influence on me. I feel that the mathematics students in elementary and middle schools have been pitted (all forced to learn for further education), which is far less practical. Twelve years of education has learned a bunch of chickens and rabbits in the same cage, quadratic equation roots, conic section , Spatial three-dimensional geometry, inequalities, I really feel that the knowledge system is very old, there is no real value, it is the same as playing. You see, it is useless to follow this logic and mathematics (fog). So what’s wrong with your logic, because you What I learn now is the basics! The basics may not be easy to apply (but it is undeniable that the seemingly basic things such as mechanics can and can bring a lot of guidance to real life), but without the basics, you can’t get in touch with deeper things. Don’t agree. What do I say about mastering finite element in seven days? If you don’t have a foundation in mechanics, the finite element software is more like a drawing software in your hands. The mechanical coupling in the model is difficult to judge for people with no foundation in mechanics. If you talk about programming, I can Not too sleepy, there are still big shortcomings in the development of software in the field of mechanics! In fact, many engineering problems are not only to solve the problem, but it is best to propose a template solution or tool (engineering software) to solve the problem. Then The path of computer programming is not impossible in the direction of mechanics.
