The formal language used in scientific research is very different from the natural language used in daily life. Formal language looks like a book of heaven, far away from the public, and only some professionals can understand and use it. But in fact, this is a misunderstanding. The relationship between natural language and formal language is like the relationship between the naked eye and the microscope. The naked eye has a wide field of vision and can grasp the information of things as a whole: a microscope can help people see the details and subtleties of things, even though they can be seen in a small range. 
The development of science has improved the daily life of ordinary people to a great extent, but people do not realize the importance of formal language, which is the basis of scientific expression
 both formal language and natural language are important tools for people to communicate and understand information.
