CyberpunkCyberpunk is a subgenre of science fiction in a dystopian futuristic setting that tends to focus on a "combination of lowlife and high tech", featuring futuristic technological and scientific achievements, such as artificial intelligence and cyberware, juxtaposed with societal collapse, dystopia or decay. Much of cyberpunk is rooted in the New Wave science fiction movement of the 1960s and 1970s, when writers like Philip K. Dick, Michael Moorcock, Roger Zelazny, John Brunner, J. G.
Cyberpunk derivativesSince the advent of the cyberpunk genre, a number of derivatives of cyberpunk have become recognized in their own right as distinct subgenres in speculative fiction, especially in science fiction. Rather than necessarily sharing the digitally and mechanically focused setting of cyberpunk, these derivatives can display other futuristic, or even retrofuturistic, qualities that are drawn from or analogous to cyberpunk: a world built on one particular technology that is extrapolated to a highly sophisticated level (this may even be a fantastical or anachronistic technology, akin to retrofuturism), a gritty transreal urban style, or a particular approach to social themes.
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.
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.
DystopiaA dystopia (), also called a cacotopia or anti-utopia, is a speculated community or society that is undesirable or frightening. It is often treated as an antonym of utopia, a term that was coined by Sir Thomas More and figures as the title of his best known work, published in 1516, which created a blueprint for an ideal society with minimal crime, violence, and poverty. The relationship between utopia and dystopia is in actuality, not one simple opposition, as many utopian elements and components are found in dystopias as well, and vice versa.
FantasyFantasy is a genre of speculative fiction involving magical elements, typically set in a fictional universe and usually inspired by mythology or folklore. The term "fantasy" can also be used to describe a "work of this genre", usually literary. Its roots are in oral traditions, which became fantasy literature and drama. From the twentieth century, it has expanded further into various media, including film, television, graphic novels, manga, animations and video games.
Matrix (mathematics)In mathematics, a matrix (plural matrices) is a rectangular array or table of numbers, symbols, or expressions, arranged in rows and columns, which is used to represent a mathematical object or a property of such an object. For example, is a matrix with two rows and three columns. This is often referred to as a "two by three matrix", a " matrix", or a matrix of dimension . Without further specifications, matrices represent linear maps, and allow explicit computations in linear algebra.
Orthogonal matrixIn linear algebra, an orthogonal matrix, or orthonormal matrix, is a real square matrix whose columns and rows are orthonormal vectors. One way to express this is where QT is the transpose of Q and I is the identity matrix. This leads to the equivalent characterization: a matrix Q is orthogonal if its transpose is equal to its inverse: where Q−1 is the inverse of Q. An orthogonal matrix Q is necessarily invertible (with inverse Q−1 = QT), unitary (Q−1 = Q∗), where Q∗ is the Hermitian adjoint (conjugate transpose) of Q, and therefore normal (Q∗Q = QQ∗) over the real numbers.
Utopian and dystopian fictionUtopian and dystopian fiction are subgenres of science fiction that explore social and political structures. Utopian fiction portrays a setting that agrees with the author's ethos, having various attributes of another reality intended to appeal to readers. Dystopian fiction offers the opposite: the portrayal of a setting that completely disagrees with the author's ethos. Some novels combine both genres, often as a metaphor for the different directions humanity can take depending on its choices, ending up with one of two possible futures.
Toeplitz matrixIn linear algebra, a Toeplitz matrix or diagonal-constant matrix, named after Otto Toeplitz, is a matrix in which each descending diagonal from left to right is constant. For instance, the following matrix is a Toeplitz matrix: Any matrix of the form is a Toeplitz matrix. If the element of is denoted then we have A Toeplitz matrix is not necessarily square. A matrix equation of the form is called a Toeplitz system if is a Toeplitz matrix. If is an Toeplitz matrix, then the system has at-most only unique values, rather than .
Logarithm of a matrixIn mathematics, a logarithm of a matrix is another matrix such that the matrix exponential of the latter matrix equals the original matrix. It is thus a generalization of the scalar logarithm and in some sense an inverse function of the matrix exponential. Not all matrices have a logarithm and those matrices that do have a logarithm may have more than one logarithm. The study of logarithms of matrices leads to Lie theory since when a matrix has a logarithm then it is in an element of a Lie group and the logarithm is the corresponding element of the vector space of the Lie algebra.
Adjacency matrixIn graph theory and computer science, an adjacency matrix is a square matrix used to represent a finite graph. The elements of the matrix indicate whether pairs of vertices are adjacent or not in the graph. In the special case of a finite simple graph, the adjacency matrix is a (0,1)-matrix with zeros on its diagonal. If the graph is undirected (i.e. all of its edges are bidirectional), the adjacency matrix is symmetric. The relationship between a graph and the eigenvalues and eigenvectors of its adjacency matrix is studied in spectral graph theory.
Hybrid vehicleA hybrid vehicle is one that uses two or more distinct types of power, such as submarines that use diesel when surfaced and batteries when submerged. Other means to store energy include pressurized fluid in hydraulic hybrids. Hybrid powertrains are designed to switch from one power source to another to maximize both fuel efficiency and energy efficiency. In hybrid electric vehicles, for instance, the electric motor is more efficient at producing torque, or turning power, while the combustion engine is better for maintaining high speed.
Laplacian matrixIn the mathematical field of graph theory, the Laplacian matrix, also called the graph Laplacian, admittance matrix, Kirchhoff matrix or discrete Laplacian, is a matrix representation of a graph. Named after Pierre-Simon Laplace, the graph Laplacian matrix can be viewed as a matrix form of the negative discrete Laplace operator on a graph approximating the negative continuous Laplacian obtained by the finite difference method. The Laplacian matrix relates to many useful properties of a graph.
Star WarsStar Wars is an American epic space opera multimedia franchise created by George Lucas, which began with the eponymous 1977 film and quickly became a worldwide pop culture phenomenon. The franchise has been expanded into various films and other media, including television series, video games, novels, comic books, theme park attractions, and themed areas, comprising an all-encompassing fictional universe. Star Wars is one of the highest-grossing media franchises of all time.
Lego Star WarsLego Star Wars is a Lego theme and multimedia franchise revolving around the Star Wars media franchise created by George Lucas. Part of the theme are, next to, over 883 Lego construction toy sets 1328 Lego minifigures, an eponymous video game series, containing six games, multiple computer animated short films and TV series. Originally it was only licensed from 1999 to 2008, but The Lego Group extended the license with Lucasfilm, first until 2011, then until 2016, then again until 2022, and then once more until 2032.
Star Wars video gamesOver one hundred video games based on the Star Wars franchise have been released, dating back to some of the earliest home consoles. Some are based directly on films while others rely heavily on the Star Wars Expanded Universe. Star Wars games have gone through three significant development eras: early licensed games (1979–1993), games developed after the creation of LucasArts (1993–2013), and games created after the closure of LucasArts (2014–present), which are currently licensed to Electronic Arts, and include an EA Star Wars logo.
Hybrid vehicle drivetrainHybrid vehicle drivetrains transmit power to the driving wheels for hybrid vehicles. A hybrid vehicle has multiple forms of motive power. Hybrids come in many configurations. For example, a hybrid may receive its energy by burning gasoline, but switch between an electric motor and a combustion engine. Electrical vehicles have a long history combining internal combustion and electrical transmission - as in a diesel–electric power-train - although they have mostly been used for rail locomotives.
Plug-in hybridA plug-in hybrid electric vehicle (PHEV) is a hybrid electric vehicle whose battery pack can be recharged by plugging a charging cable into an external electric power source, in addition to internally by its on-board internal combustion engine-powered generator. Most PHEVs are passenger cars, but there are also PHEV versions of sports cars, commercial vehicles and vans, utility trucks, buses, trains, motorcycles, mopeds, and even military vehicles.
