Mathematical fiction is a genre of creative fictional work in which mathematics and mathematicians play important roles. The form and the medium of the works are not important. The genre may include poems, short stories, novels or plays; comic books; films, videos, or audios.
Blunt cones can be excluded from the definition of convex cone by substituting "non-negative" for "positive" in the condition of α, β. A cone is called flat if it contains some nonzero vector x and its opposite −x, meaning C contains a linear subspace of dimension at least one, and salient otherwise.
"A science fiction story is a story built around human beings, with a human problem, and a human solution, which would not have happened at all without its scientific content." [13] Basil Davenport. 1955. "Science fiction is fiction based upon some imagined development of science, or upon the extrapolation of a tendency in society." [14] Edmund ...
A cone from N to F is a family of morphisms : for each object X of J, such that for every morphism f : X → Y in J the following diagram commutes: Part of a cone from N to F. The (usually infinite) collection of all these triangles can be (partially) depicted in the shape of a cone with the apex N.
Science fiction is a genre of fiction. It differs from fantasy in that, within the context of the story , its imaginary elements are largely possible within scientifically established or scientifically postulated laws of nature (though some elements in a story might still be pure imaginative speculation).
Science fiction (sometimes shortened to sci-fi or abbreviated SF) 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.
Cone of a circle. The original space X is in blue, and the collapsed end point v is in green.. In topology, especially algebraic topology, the cone of a topological space is intuitively obtained by stretching X into a cylinder and then collapsing one of its end faces to a point.
Science fiction – genre of fiction dealing with the impact of imagined innovations in science or technology, often in a futuristic setting. [2] [3] [4] Exploring the consequences of such innovations is the traditional purpose of science fiction, making it a "literature of ideas". [5] Pornography
