Some hard SF writers have also worked as professional scientists.
A few of these scientist/writers are Gregory Benford and Geoffrey A.
Although not everyone agrees on the exact definitions of these two types, the way they use science or the type of science used in the stories is different.
Hard science fiction, or "hard SF", is special because it uses true facts and theories from sciences.
It is an umbrella term, encompassing the sub genres of fantasy, science fiction and horror, as well as other strange and amazing tales which do not fit any other category.
Two speculative fiction texts which both reflect and challenge the genre are George Lucas' Star Wars and Isabel Allende's City of the Beasts.City of the Beasts is a work of magical realism, meaning that, rather than conducting a thought experiment as in all other speculative fiction works, it attempts to show the world from a different perspective.It tells a story from the perspective of people who live in our world but experience a different reality to the one we call objective.Each subgenre is a group of stories that uses similar ideas or styles of writing.Publishing companies and critics put works of SF into different subgenres to help describe the work to help readers choose which books to read or movies to watch. Some stories can be in two or more genres at the same time. In Alternate (or alternative) history stories, writers imagine how the past might have been different.The two works are from entirely different ends of the speculative fiction spectrum.At one end, we have Star Wars, classified under the sub-genre of science fiction.These are some important alternate history books: The Sidewise Award is for the best works in this subgenre.The name Sidewise is taken from Murray Leinster's 1934 story "Sidewise in Time." Harry Turtledove is one of the most famous writers in the subgenre.Some people think that satirical novels in fantastic settings (places) such as Gulliver's Travels by Jonathan Swift are speculative fiction.Within Hard or Soft SF, there are different types, or subgenres, of science fiction.
