Popular science literature - literary works about science, scientific achievements and scientists, intended for a wide range of readers.
Popular science literature is designed both for specialists from other fields of knowledge and for poorly trained readers, including children and adolescents.
Popular science literature includes works on the foundations and individual problems of fundamental and applied sciences, biographies of scientists, descriptions of travels, etc., written in various genres.
The best popular essays promote the achievements of science in a form that is most accessible to the readers to whom they are intended. Non-fiction literature is adjacent to popular science literature.
Popular knowledge sensu stricto is knowledge not for specialists, but for a wide range of adult amateurs with a general education. Therefore, it cannot be considered an introductory science; school textbooks serve these purposes, not popular books. A characteristic feature of the popular presentation of scientific knowledge is the lack of details and, above all, controversial opinions, as a result of which this knowledge appears artificially simplified. The form of this presentation has artistic appeal, liveliness and accessibility. More importantly, it is presented in an apodictic manner that allows one to simply accept or reject points of view. Simplification, imagery and apodicticity of judgments are the most characteristic features of exoteric knowledge.
