The boundaries of science-fiction in Isaac Asimov's novels
Of course there are a lot of other types of SF, outside or in between the categories named above, like: time-travel (the main theme focuses on the travel of people in other time frames, mainly in the future, where they discover a new and distorted society), alternate history (the main theme in this kind of science fiction is concerned with how the world would have been changed if some moments in t[...]DOWNLOAD REFERAT

concerned with military technology and new weapons and warfare techniques), new-wave science fiction, apocalyptic fiction (deals with the vision on what would the end of the world or of the mankind be like ) or Christian science fiction (dealing with future development of the religion). There are of course other genres that come close to the science fiction genre like fantasy and horror, but they just skim on the edge of the universes depicted in the actual SF stories. This does not mean that either of the genres cannot borrow themes or motifs from one another.
So there are a lot of categories of science fiction out there, but in the following lines I will try to give examples of the main three genres that have had the most impact on our society, being the dominant choices for 90% of the written science fiction out on the shelves.
The first category is hard science fiction. It is characterized by an extremely strong focus of the author on the accuracy of the sciences like physics, astronomy and chemistry, to describe as accurately as possible scientific facts, and to make them as plausible as possible in the eyes of the readers.
What is described by some readers / reviewers as hard SF is, in my opinion, more likely to be a "near-future fiction". That is, if the science and technology described in the story is almost the same as ours but with some staggering differenciesdifferences, then we may imagine, or know that it really could work in the real life and we can believe in it or think at it as beyngbeing plausible. Since it works, the science must be accurate. Since the science is accurate, it's "hard SF" [08.27.1988] Dr. Isaac Asimov talks with Slawek Wojtowicz, Interview, http://www.asimovonline.com/asimov_home_page.html [17.06.2008]).

Many of the authors that write hard science fiction worked in science related fields, contributed to the scientific discoveries, and researched new technologies, and alternate ways of use for different objects. Other authors, who don't contribute actively to the scientific world, like Isaac Asimov (who got a Master's degree in Chemistry, at the Columbia University in the year 1941) keep themselves informed of the cutting edge scientific discoveries, as Asimov himself in an interview said: "I read mostly non-fiction: new books on science, mathematics, things like that. Most of the stuff I write, except for my novels, is non-fiction. I have to keep up with science." « mai multe referate din Engleza
