Of course, I have a good knowledge of mathematics, and English is also very important.
An engineer is someone who can operate, design, manage and evaluate an engineering system. The word "engineer" is usually only used for people who have a professional degree or equivalent work experience in an engineering field.
Engineers and scientists are often confused. Scientists try to explore nature in order to discover universal principles, while engineers follow these established principles to solve some technical problems in mathematics and science. Scientists study things, engineers build things. Scientists explore the world to discover universal laws, while engineers use universal laws to design practical objects.
Engineer is a kind of professional level evaluation (professional title evaluation). Under it, there are technicians, assistant engineers and other titles; Have the title of senior engineer and professor-level senior engineer. Of course, this is only a calibration of the technical level of personnel engaged in engineering construction or management.
According to the professional title (qualification), it is divided into: researcher or professor senior engineer (senior), senior engineer (deputy senior), engineer (intermediate) and assistant engineer (junior).
