Popular sources are usually written with a general audience in mind and are intended to be understood by someone who has little science background. It can be a bridge between the literature of scientific research and that of popular discourse. The goal is often to capture the methods and accuracy of science while making the language more accessible for the understanding of the non-specialist. It often makes use of metaphors and analogies to explain difficult scientific concepts. It also can explore ideas overlooked by specialists or that fall outside the established discipline. This can produce a synthesis of new ideas that can cross multiple fields and offer new applications in other academic specialties. There is often more emphasis on the entertainment value or personal relevance to the general audience. --- Wikipedia
