Three body

Three body may refer to:


In physics and classical mechanics, the three-body problem is the problem of taking the initial positions and velocities of three point masses and solving for their subsequent motion according to Newton's laws of motion and Newton's law of universal gravitation. The three-body problem is a special case of the n-body problem. Unlike two-body problems, no closed-form solution exists for all sets of initial conditions, and numerical methods are generally required.

In physics and astronomy, Euler's three-body problem is to solve for the motion of a particle that is acted upon by the gravitational field of two other point masses that are fixed in space. This problem is exactly solvable, and yields an approximate solution for particles moving in the gravitational fields of prolate and oblate spheroids. This problem is named after Leonhard Euler, who discussed it in memoirs published in 1760. Important extensions and analyses were contributed subsequently by Lagrange, Liouville, Laplace, Jacobi, Darboux, Le Verrier, Velde, Hamilton, Poincaré, Birkhoff and E. T. Whittaker, among others.

Three-body force

A three-body force is a force that does not exist in a system of two objects but appears in a three-body system. In general, if the behaviour of a system of more than two objects cannot be described by the two-body interactions between all possible pairs, as a first approximation, the deviation is mainly due to a three-body force.

Hard science fiction science fiction with emphasis on scientific or technical detail, or on scientific accuracy

Hard science fiction is a category of science fiction characterized by an emphasis on scientific accuracy. The term was first used in print in 1957 by P. Schuyler Miller in a review of John W. Campbell's Islands of Space in the November issue of Astounding Science Fiction. The complementary term soft science fiction, formed by analogy to hard science fiction, first appeared in the late 1970s. The term is formed by analogy to the popular distinction between the "hard" (natural) and "soft" (social) sciences. Science fiction critic Gary Westfahl argues that neither term is part of a rigorous taxonomy; instead they are approximate ways of characterizing stories that reviewers and commentators have found useful.

Science fiction genre of fiction

Science fiction is a genre of speculative fiction, typically dealing with imaginative concepts such as advanced science and technology, space exploration, time travel, and extraterrestrial life. Science fiction often explores the potential consequences of scientific and other innovations, and has been called a "literature of ideas".

Theoretical chemistry academic field

Theoretical chemistry is a branch of chemistry, which develops theoretical generalizations that are part of the theoretical arsenal of modern chemistry, for example, the concept of chemical bonding, chemical reaction, valence, the surface of potential energy, molecular orbitals, orbital interactions, molecule activation etc.

<i>The Invisible Man</i> 1897 science fiction novella by H. G. Wells

The Invisible Man is a science fiction novel by H. G. Wells. Originally serialized in Pearson's Weekly in 1897, it was published as a novel the same year. The Invisible Man of the title is Griffin, a scientist who has devoted himself to research into optics and invents a way to change a body's refractive index to that of air so that it neither absorbs nor reflects light and thus becomes invisible. He successfully carries out this procedure on himself, but fails in his attempt to reverse it. An enthusiast of random and irresponsible violence, Griffin has become an iconic character in horror fiction.

The use of nanotechnology in fiction has attracted scholarly attention. The first use of the distinguishing concepts of nanotechnology was "There's Plenty of Room at the Bottom", a talk given by physicist Richard Feynman in 1959. K. Eric Drexler's 1986 book Engines of Creation introduced the general public to the concept of nanotechnology. Since then, nanotechnology has been used frequently in a diverse range of fiction, often as a justification for unusual or far-fetched occurrences featured in speculative fiction.

The Body Snatchers is a 1955 science fiction novel by American writer Jack Finney, originally serialized in Colliers Magazine in 1954, which describes real-life Mill Valley, California being invaded by seeds that have drifted to Earth from space. The seeds, grown from plantlike pods, replace sleeping people with perfect physical duplicates with all the same knowledge, memories, scars, etc. but are incapable of human emotion or feeling. The human victims disappear forever.

<i>The Three-Body Problem</i> (novel) 2008 science fiction novel by Liu Cixin

The Three-Body Problem is a science fiction novel by the Chinese writer Liu Cixin. It is the first novel of the Remembrance of Earth's Past trilogy, but Chinese readers generally refer to the whole series by the title of this first novel. The second and third novels in the trilogy are titled The Dark Forest and Death's End. The title of the first novel refers to the three-body problem in orbital mechanics.

The End of Time may refer to:

Quantum fiction is a literary genre that reflects modern experience of the material world and reality as influenced by quantum theory and new principles in quantum physics. The genre is not necessarily science-themed and blurs the line separating science fiction and fantasy into a broad scope of mainstream literature that transcends the mechanical model of science and involves the fantasy of human perception or imagination as realistic components affecting the every day physical world. Quantum fiction is characterized by the use of an element in quantum mechanics as a storytelling device. In quantum fiction, everyday life hinges on some aspect of the quantum nature of reality.

Remembrance of Earth's Past is a science fiction trilogy by the Chinese writer Liu Cixin, but Chinese readers generally refer to the series by the title of its first novel, The Three Body Problem (Chinese: 三体; literally: 'Three-Body').

Organ transplantation is a common theme in science fiction and horror fiction. Numerous horror movies feature the theme of transplanted body parts that are evil or give supernatural powers, with examples including Body Parts, Hands of a Stranger, and The Eye.
