Science journalism conveys reporting about science to the public. The field typically involves interactions between scientists, journalists and the public.
Emma Reh (1896–1982) was a science journalist for the Science Service in the 1920s and 1930s. Here she can be seen reporting on an archaeological site in Oaxaca for Science News.
Popular science is an interpretation of science intended for a general audience. While science journalism focuses on recent scientific developments, popular science is more broad ranging. It may be written by professional science journalists or by scientists themselves. It is presented in many forms, including books, film and television documentaries, magazine articles, and web pages.
