Most materials jobs are engaged in some research work, and the research funds invested in the early stage will be relatively high. However, due to limited funds, many companies often buy directly and then make some minor changes, so the recruited personnel will not conduct too many experiments, resulting in low income and poor employment prospects for undergraduate graduates. Moreover, there is little demand for materials specialty in the market. Unless you are a particularly excellent materials research engineer, it is difficult to find a professional counterpart.

2. Learning is boring.

There are many knowledge points to memorize in the material class. He spends most of his time doing experiments. Every time he finishes an experiment, he will ask his classmates to write an experiment report. Many students don't like it, so he thinks the material major is a pit.

This experiment is very dangerous.

During 2065438+2008, students from the Department of Municipal Environmental Engineering of Beijing Jiaotong University conducted a scientific research experiment on landfill leachate sewage treatment in the Environmental Engineering Laboratory of Building 2 in the east campus of the school. An explosion occurred at the experimental site, killing three students who participated in the experiment. Materials class also needs a lot of experiments, and accidents will inevitably happen during it.

It is too difficult to change majors.

The knowledge of materials specialty is not theoretical enough, most of them are summative, and there is no deep requirement for mathematics and physics. So it's a bit difficult to study for a master's degree or change majors.

Of course, the material specialty is not without a way out. Material major has a great advantage, that is, "it is easier to upgrade academic qualifications", which is the advantage of "Tiankeng major". For ordinary undergraduate candidates, as long as they are willing to work hard, it is relatively simple to get into the 985 and double-class graduate students, because biochemistry and environmental materials recruit a large number of students every year. However, due to the small number of applicants, it is easy to pass the retest.

Summary: There is no distinction between good and bad majors. The so-called Tiankeng major is only in small demand at present, but if candidates blindly pursue popular majors, it will also lead to oversupply in the market and it is also difficult to find a good job. So you'd better choose a major that suits you and be willing to fight for it.
