Information: - Science fiction (often shortened to SF, sci-fi or scifi) is a genre of speculative fiction, typically dealing with imaginative concepts such as futuristic science and technology, space travel, time travel, faster than light travel, parallel universes, and extraterrestrial life. Science fiction often explores the potential consequences of scientific and other innovations, and has been called a "literature of ideas." It usually avoids the supernatural, and unlike the related genre of fantasy, historically science fiction stories were intended to have a grounding in science-based fact or theory at the time the story was created, but this connection is now limited to hard science fiction. - Galaxy Science Fiction was an American digest-size science fiction magazine, published from 1950 to 1980. It was founded by an Italian company, World Editions, which was looking to break into the American market. World Editions hired as editor H. L. Gold, who rapidly made "Galaxy" the leading science fiction (sf) magazine of its time, focusing on stories about social issues rather than technology. - Poul William Anderson (November 25, 1926 July 31, 2001) was an American science fiction author who began his career during the Golden Age of the genre and continued to write and remain popular into the 21st century. Anderson also authored several works of fantasy, historical novels, and a prodigious number of short stories. He received numerous awards for his writing, including seven Hugo Awards and three Nebula Awards. - Hard science fiction is a category of science fiction characterized by an emphasis on scientific accuracy. The term was first used in print in 1957 by P. Schuyler Miller in a review of John W. Campbell, Jr.'s "Islands of Space" in "Astounding Science Fiction". The complementary term soft science fiction, formed by analogy to hard science fiction, first appeared in the late 1970s. The term is formed by analogy to the popular distinction between the "hard" (natural) and "soft" (social) sciences. Science fiction critic Gary Westfahl argues that neither term is part of a rigorous taxonomy; instead they are approximate ways of characterizing stories that reviewers and commentators have found useful. - Fantasy is a fiction genre set in an imaginary universe, often but not always without any locations, events, or people from the real world. Most fantasy uses magic or other supernatural elements as a main plot element, theme, or setting. Magic and magical creatures are common in many of these imaginary worlds. Fantasy is generally distinguished from the genres of science fiction and horror by the expectation that it steers clear of scientific and macabre themes, respectively, though there is a great deal of overlap between the three, all of which are subgenres of speculative fiction. - Gary Wesley Westfahl (born May 7, 1951) is a scholarly author and reviewer of science fiction. He has written reviews for the "Los Angeles Times", "The Internet Review of Science Fiction" and Locus Online. He worked at the University of California, Riverside until 2011 and is now an Adjunct Professor at the University of La Verne. - Tau Zero is a hard science fiction novel by Poul Anderson .

It was nominated for the Hugo Award for Best Novel in 1971 . - Horace Leonard "H. L." Gold (April 26, 1914 February 21, 1996) was an American science fiction writer and editor. Born in Canada, Gold moved to the United States at the age of two. He was most noted for bringing an innovative and fresh approach to science fiction while he was the editor of "Galaxy Science Fiction", and also wrote briefly for DC Comics. - Islands of Space is a science fiction novel by author John W.
