[Q]: Information: - A video game is an electronic game that involves human or animal interaction with a user interface to generate visual feedback on a video device such as a TV screen or computer monitor. The word "video" in "video game" traditionally referred to a raster display device, but as of the 2000s, it implies any type of display device that can produce two- or three-dimensional images. Some theorists categorize video games as an art form, but this designation is controversial. - A film, also called a movie, motion picture, theatrical film or photoplay, is a series of still images which, when shown on a screen, creates the illusion of moving images due to the phi phenomenon. This optical illusion causes the audience to perceive continuous motion between separate objects viewed rapidly in succession. The process of filmmaking is both an art and an industry. A film is created by photographing actual scenes with a motion picture camera; by photographing drawings or miniature models using traditional animation techniques; by means of CGI and computer animation; or by a combination of some or all of these techniques and other visual effects. - Fiction is the classification for any story or universe derived from imaginationin other words, not based strictly on history or fact. Fiction can be expressed in a variety of formats, including writings, live performances, films, television programs, animations, video games, and role-playing games, though the term originally and most commonly refers to the narrative forms of literature (see "literary" fiction), including the novel, novella, short story, and play. Fiction constitutes an act of creative invention, so that faithfulness to reality is not typically assumed; in other words, fiction is not expected to present only characters who are actual people or descriptions that are factually true. The context of fiction is generally open to interpretation, due to fiction's freedom from any necessary embedding in reality; however, some fictional works are claimed to be, or marketed as, historically or factually accurate, complicating the traditional distinction between fiction and non-fiction. Fiction is a classification or category, rather than a specific mode or genre, unless used in a narrower sense as a synonym for a particular literary fiction form. - For the Robert A. Heinlein short story collection , see Expanded Universe ( Heinlein ) . The term expanded universe ( sometimes called an extended universe ) is generally used to denote the ' extension ' of a media franchise ( i.e. a television show , series of featured films , etc. ) with other media ( generally comics and original novels ) . This typically involves new adventures for existing characters already developed within the franchise ; however in some case entirely new characters and complex mythology are developed . This is not the same as an adaptation , which is a retelling of the same story , usually on a different medium . Nearly every media franchise with a committed fan base has some form of expanded universe . A very popular example of this is fan fictions . Fan fictions are stories created by a fan base that portrays existing characters in new and different ways . - Literature, in its broadest sense, is any single body of written works. More restrictively, it is writing considered as an art form, or any single writing deemed to have artistic or intellectual value, often due to deploying language in ways that differ from ordinary usage. Its Latin root "literatura"/"litteratura" (derived itself from "littera": "letter" or "handwriting") was used to refer to all written accounts, though contemporary definitions extend the term to include texts that are spoken or sung (oral literature). Literature can be classified according to whether it is fiction or non-fiction and whether it is poetry or prose; it can be further distinguished according to major forms such as the novel, short story or drama; and works are often categorized according to historical periods or their adherence to certain aesthetic features or expectations (genre). - A television program is a segment of content intended for broadcast on over-the-air, cable television, or Internet television, other than a commercial, trailer, or any other segment of content not serving as attraction for viewership. It may be a single production, or more commonly, a series of related productions (also called a television series or a television show). - A media franchise is a set of related media in which several derivative works have been produced from an original creative work (usually that of fiction), such as a film, a work of literature, a television program or a video game. A media franchise is characterized by its components generally sharing a common fictional universe. - A fictional universe is a self-consistent imaginary setting with events, and often other elements, that differ from the real world. It may also be called an imagined, constructed or fictional realm (or world). Fictional universes may appear in novels, comics, films, television shows, video games and other creative works.

[Q]: Information: - Klaus Friedrich Roth ( 29 October 1925 -- 10 November 2015 ) was a German - born British mathematician known for work on diophantine approximation , the large sieve , and irregularities of distribution . - In mathematics, a real number is a value that represents a quantity along a line. The adjective "real" in this context was introduced in the 17th century by Rene Descartes, who distinguished between real and imaginary roots of polynomials. - In mathematics, analytic number theory is a branch of number theory that uses methods from mathematical analysis to solve problems about the integers. It is often said to have begun with Peter Gustav Lejeune Dirichlet's 1837 introduction of Dirichlet "L"-functions to give the first proof of Dirichlet's theorem on arithmetic progressions. It is well known for its results on prime numbers (involving the Prime Number Theorem and Riemann zeta function) and additive number theory (such as the Goldbach conjecture and Waring's problem). Branches of analytic number theory. Analytic number theory can be split up into two major parts, divided more by the type of problems they attempt to solve than fundamental differences in technique. - The large sieve is a method (or family of methods and related ideas) in analytic number theory. - In number theory, the field of Diophantine approximation deals with the approximation of real numbers by rational numbers. It is named after Diophantus of Alexandria. - Number theory or, in older usage, arithmetic is a branch of pure mathematics devoted primarily to the study of the integers. It is sometimes called "The Queen of Mathematics" because of its foundational place in the discipline. Number theorists study prime numbers as well as the properties of objects made out of integers (e.g., rational numbers) or defined as generalizations of the integers (e.g., algebraic integers). - In mathematics, a rational number is any number that can be expressed as the quotient or fraction "p"/"q" of two integers, a numerator "p" and a non-zero denominator "q". Since "q" may be equal to1, every integer is a rational number. The set of all rational numbers, often referred to as "the rationals", is usually denoted by a boldface Q (or blackboard bold formula_1, Unicode ); it was thus denoted in 1895 by Giuseppe Peano after "quoziente", Italian for "quotient".
