Science fiction is writing that is based on an imaginary technological or scientific advance, or a dramatic and imaginary change in our world and the way we live. Science fiction takes many forms - ranging from often literary novels like those of Jules Verne or H.G. Wells, to the more popular ones of Isaac Asimov, to comics and cartoon strips.

The line between science fiction and fantasy often blurs, as in the stories of Ray Bradbury for instance, or in the Artemis Fowl novels of Eoin Colfer.

Ideas and concepts put forward in science fiction have often had significant impact on philosophical, social, and scientific thought.

One such concept for you to read about is:
Isaac Asimov's The Three Laws of Robotics.
