The popular science is the version that is given to the general community, not for scientist or students.
The popular science is presented in many forms, included documentary TV programs and magazine expose.
The quality of the popular science varies.
The best popular science is product of creative people in science with skills in communication to show the topic in a neutral vision.
Some popular sciences can be tricky.
Some are produced by people with no knowledge about the issue that they interpret what so ever.
Some are create by people with a partial vision.
Unfortunately, it could be complicated to identify the articles or fiction documentaries.
In the case of the medical investigation, the results are often presented by the press with no appropriate background.
The popular science could also exceed the limits of formal science to the pseudoscience.
The popular science occasionally turns to focus in sensationalist subjects like new diets, the theory of chaos, brakes in time or conation.
Famous writers that made science so popular were: Isaac Asimov, Richard Dawking, Stephen Hawking, Stephen Jay Gould, Brian Greene, Oliver Sacks and Carl Sagan.
In addition, there are some famous communication sources like the Discovery channel, the museum Exploratorium, the web site HowStuffWorks, the magazine New Scientist, the TV show Nova, the magazine Scientific American and the museum and magazine Smithsonian.
Therefore, people that are interested in real, neutral science information should search in serious resources and not TV, popular magazines, movies or informal web sites in internet.
