NarrativeA narrative, story, or tale is any account of a series of related events or experiences, whether nonfictional (memoir, biography, news report, documentary, travelogue, etc.) or fictional (fairy tale, fable, legend, thriller, novel, etc.). Narratives can be presented through a sequence of written or spoken words, through still or moving images, or through any combination of these. The word derives from the Latin verb narrare (to tell), which is derived from the adjective gnarus (knowing or skilled). Narration (i.
LiteratureLiterature is any collection of written work, but it is also used more narrowly for writings specifically considered to be an art form, especially prose fiction, drama, poetry, and including both print and digital writing. In recent centuries, the definition has expanded to include oral literature, also known as orature much of which has been transcribed. Literature is a method of recording, preserving, and transmitting knowledge and entertainment, and can also have a social, psychological, spiritual, or political role.
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.
Complexity classIn computational complexity theory, a complexity class is a set of computational problems "of related resource-based complexity". The two most commonly analyzed resources are time and memory. In general, a complexity class is defined in terms of a type of computational problem, a model of computation, and a bounded resource like time or memory. In particular, most complexity classes consist of decision problems that are solvable with a Turing machine, and are differentiated by their time or space (memory) requirements.
Computational complexityIn computer science, the computational complexity or simply complexity of an algorithm is the amount of resources required to run it. Particular focus is given to computation time (generally measured by the number of needed elementary operations) and memory storage requirements. The complexity of a problem is the complexity of the best algorithms that allow solving the problem. The study of the complexity of explicitly given algorithms is called analysis of algorithms, while the study of the complexity of problems is called computational complexity theory.
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.
Space colonizationSpace colonization (also called space settlement or extraterrestrial colonization) is the use of outer space or celestial bodies other than Earth for permanent habitation or as extraterrestrial territory. The inhabitation and territorial use of extraterrestrial space has been proposed, for example, for space settlements or extraterrestrial mining enterprises. To date, no permanent space settlement other than temporary space habitats have been set up, nor has any extraterrestrial territory or land been legally claimed.
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).
StorytellingStorytelling is the social and cultural activity of sharing stories, sometimes with improvisation, theatrics or embellishment. Every culture has its own stories or narratives, which are shared as a means of entertainment, education, cultural preservation or instilling moral values. Crucial elements of stories and storytelling include plot, characters and narrative point of view. The term "storytelling" can refer specifically to oral storytelling but also broadly to techniques used in other media to unfold or disclose the narrative of a story.
Computational complexity theoryIn theoretical computer science and mathematics, computational complexity theory focuses on classifying computational problems according to their resource usage, and relating these classes to each other. A computational problem is a task solved by a computer. A computation problem is solvable by mechanical application of mathematical steps, such as an algorithm. A problem is regarded as inherently difficult if its solution requires significant resources, whatever the algorithm used.
Non-fictionNon-fiction (or nonfiction) is any document or media content that attempts, in good faith, to convey information only about the real world, rather than being grounded in imagination. Non-fiction typically aims to present topics objectively based on historical, scientific, and empirical information. However, some non-fiction ranges into more subjective territory, including sincerely held opinions on real-world topics.
Parameterized complexityIn computer science, parameterized complexity is a branch of computational complexity theory that focuses on classifying computational problems according to their inherent difficulty with respect to multiple parameters of the input or output. The complexity of a problem is then measured as a function of those parameters. This allows the classification of NP-hard problems on a finer scale than in the classical setting, where the complexity of a problem is only measured as a function of the number of bits in the input.
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.
Narrative poetryNarrative poetry is a form of poetry that tells a story, often using the voices of both a narrator and characters; the entire story is usually written in metered verse. Narrative poems do not need to rhyme. The poems that make up this genre may be short or long, and the story it relates to may be complex. It is normally dramatic, with various characters. Narrative poems include all epic poetry, and the various types of "lay", most ballads, and some idylls, as well as many poems not falling into a distinct type.
Colonization of VenusThe colonization of Venus has been a subject of many works of science fiction since before the dawn of spaceflight, and is still discussed from both a fictional and a scientific standpoint. However, with the discovery of Venus's extremely hostile surface environment, attention has largely shifted towards the colonization of the Moon and Mars instead, with proposals for Venus focused on habitats floating in the upper-middle atmosphere and on terraforming.
Space complexityThe space complexity of an algorithm or a computer program is the amount of memory space required to solve an instance of the computational problem as a function of characteristics of the input. It is the memory required by an algorithm until it executes completely. This includes the memory space used by its inputs, called input space, and any other (auxiliary) memory it uses during execution, which is called auxiliary space. Similar to time complexity, space complexity is often expressed asymptotically in big O notation, such as etc.
Arabic literatureArabic literature (الأدب العربي / ALA-LC: al-Adab al-‘Arabī) is the writing, both as prose and poetry, produced by writers in the Arabic language. The Arabic word used for literature is Adab, which is derived from a meaning of etiquette, and which implies politeness, culture and enrichment. Arabic literature emerged in the 5th century with only fragments of the written language appearing before then. The Qur'an, widely regarded as the finest piece of literature in the Arabic language, would have the greatest lasting effect on Arab culture and its literature.
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.
Colonization of the MoonColonization of the Moon is a process or concept employed by some proposals for robotic or human exploitation and settlement endeavours on the Moon. Settling of the Moon is therefore a more specific concept, for which the broader concept of colonization is often used as a synonym, a use that is contested in the light of colonialism. Laying claim to the Moon has been declared illegal through international space law and no state has made such claims, despite having a range of probes and artificial remains on the Moon.
Embryo space colonizationEmbryo space colonization is a theoretical interstellar space colonization concept that involves sending a robotic mission to a habitable terrestrial planet, dwarf planet, minor planet or natural satellite transporting frozen early-stage human embryos or the technological or biological means to create human embryos. The proposal circumvents the most severe technological problems of other mainstream interstellar colonization concepts. In contrast to the sleeper ship proposal, it does not require the more technically challenging 'freezing' of fully developed humans (see cryonics).
