FictionFiction is any creative work, chiefly any narrative work, portraying individuals, events, or places that are imaginary, or in ways that are imaginary. Fictional portrayals are thus inconsistent with history, fact, or plausibility. In a traditional narrow sense, "fiction" refers to written narratives in prose often referring specifically to novels, novellas, and short stories. More broadly, however, fiction encompasses imaginary narratives expressed in any medium, including not just writings but also live theatrical performances, films, television programs, radio dramas, comics, role-playing games, and video games.
Science fictionScience fiction (sometimes shortened to SF or sci-fi) is a genre of speculative fiction, which typically deals with imaginative and futuristic concepts such as advanced science and technology, space exploration, time travel, parallel universes, and extraterrestrial life. Science fiction can trace its roots to ancient mythology. It is related to fantasy, horror, and superhero fiction and contains many subgenres. Its exact definition has long been disputed among authors, critics, scholars, and readers.
Speculative fictionSpeculative fiction is an umbrella category of fiction that, in its broadest sense, encompasses all the genres that depart from realism, or imitating ordinary reality, such as in the context of supernatural, futuristic, and other imaginative realms. This catch-all genre thus includes, but is not limited to, science fiction, fantasy, horror, superhero fiction, alternate history, utopian and dystopian fiction, and supernatural fiction, as well as combinations thereof (for example, science fantasy).
UtopiaA utopia (juːˈtoʊpiə ) typically describes an imaginary community or society that possesses highly desirable or near-perfect qualities for its members. It was coined by Sir Thomas More for his 1516 book Utopia, which describes a fictional island society in the New World. It can also refer to an intentional community. Hypothetical utopias focus on, among other things, equality in categories such as economics, government and justice, with the method and structure of proposed implementation varying according to ideology.
Genre fictionGenre fiction, also known as formula fiction or popular fiction, is a term used in the book-trade for fictional works written with the intent of fitting into a specific literary genre in order to appeal to readers and fans already familiar with that genre. A number of major literary figures have written genre fiction. John Banville publishes crime novels as Benjamin Black, and both Doris Lessing and Margaret Atwood have written science fiction.
Techno-progressivismTechno-progressivism or tech-progressivism is a stance of active support for the convergence of technological change and social change. Techno-progressives argue that technological developments can be profoundly empowering and emancipatory when they are regulated by legitimate democratic and accountable authorities to ensure that their costs, risks and benefits are all fairly shared by the actual stakeholders to those developments.
Utopia (book)Utopia (Libellus vere aureus, nec minus salutaris quam festivus, de optimo rei publicae statu deque nova insula Utopia, "A truly golden little book, not less beneficial than enjoyable, about how things should be in a state and about the new island Utopia") is a work of fiction and socio-political satire by Thomas More (1478–1535), written in Latin and published in 1516. The book is a frame narrative primarily depicting a fictional island society and its religious, social and political customs.
Supernatural fictionSupernatural fiction or supernaturalist fiction is a genre of speculative fiction that exploits or is centered on supernatural themes, often contradicting naturalist assumptions of the real world. In its broadest definition, supernatural fiction overlaps with examples of weird fiction, horror fiction, vampire literature, ghost story, and fantasy. Elements of supernatural fiction can be found in writing from the genre of science fiction.
Technological utopianismTechnological utopianism (often called techno-utopianism or technoutopianism) is any ideology based on the premise that advances in science and technology could and should bring about a utopia, or at least help to fulfill one or another utopian ideal. A techno-utopia is therefore an ideal society, in which laws, government, and social conditions are solely operating for the benefit and well-being of all its citizens, set in the near- or far-future, as advanced science and technology will allow these ideal living standards to exist; for example, post-scarcity, transformations in human nature, the avoidance or prevention of suffering and even the end of death.
Irrational numberIn mathematics, the irrational numbers (from in- prefix assimilated to ir- (negative prefix, privative) + rational) are all the real numbers that are not rational numbers. That is, irrational numbers cannot be expressed as the ratio of two integers. When the ratio of lengths of two line segments is an irrational number, the line segments are also described as being incommensurable, meaning that they share no "measure" in common, that is, there is no length ("the measure"), no matter how short, that could be used to express the lengths of both of the two given segments as integer multiples of itself.
Quadratic irrational numberIn mathematics, a quadratic irrational number (also known as a quadratic irrational or quadratic surd) is an irrational number that is the solution to some quadratic equation with rational coefficients which is irreducible over the rational numbers. Since fractions in the coefficients of a quadratic equation can be cleared by multiplying both sides by their least common denominator, a quadratic irrational is an irrational root of some quadratic equation with integer coefficients.
Proof that π is irrationalIn the 1760s, Johann Heinrich Lambert was the first to prove that the number pi is irrational, meaning it cannot be expressed as a fraction , where and are both integers. In the 19th century, Charles Hermite found a proof that requires no prerequisite knowledge beyond basic calculus. Three simplifications of Hermite's proof are due to Mary Cartwright, Ivan Niven, and Nicolas Bourbaki. Another proof, which is a simplification of Lambert's proof, is due to Miklós Laczkovich. Many of these are proofs by contradiction.
Realism (arts)Realism in the arts is generally the attempt to represent subject matter truthfully, without artificiality and avoiding speculative and supernatural elements. The term is often used interchangeably with naturalism, although these terms are not synonymous. Naturalism, as an idea relating to visual representation in Western art, seeks to depict objects with the least possible amount of distortion and is tied to the development of linear perspective and illusionism in Renaissance Europe.
