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 content seen through the microscope may become a new landscape, indicating that formal language can enrich the expression of natural language, and we should pay attention to formal language
 both formal language and natural language are important tools for people to communicate and understand information.
