Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Popular science, sometimes called literature of science, is interpretation of science intended for a general audience. While science journalism focuses on recent scientific developments, popular science is broad-ranging, often written by scientists as well as journalists, and is presented in many formats, which can include books, television documentaries, magazine articles and web pages.Popular science is a bridge between scientific literature as a professional medium of scientific research, and the realms of popular political and cultural discourse. The goal of the genre is often to capture the methods and accuracy of science, while making the language more accessible. Many science-related controversies are discussed in popular science books and publications, such as the long-running debates over biological determinism and the biological components of intelligence, stirred by popular books such as The Mismeasure of Man and The Bell Curve.
