The meaning of "popular science" refers to the activities of using various media to make the public accept the knowledge of natural science and social science, popularize the application of science and technology, advocate scientific methods, spread scientific ideas and carry forward the scientific spirit in an easy-to-understand way. Popular science is a kind of social education.

From the perspective of sociology of science, the popularization of science is a universal social phenomenon, which inevitably has its own "growing point". The growing point of popular science lies in the intersection of nature and man, science and society. In other words, the interaction between natural science and human society has produced scientific popularization, and science and technology and society, as the "soil" of scientific popularization, have nurtured its growth.
