Night Walk (novel)
{{unreferenced, date=November 2021 ''Night Walk'' is a science fiction novel by Bob Shaw, first published in 1967. Plot Emm Luther is a planet ruled by a single, worldwide theocracy. It is evenly populated, and a couple of railroads run up and down the coasts of the largest continent. Earth sends secret agent Sam Tallon to Emm Luther to infiltrate the theocracy and extract the coordinates of the "null-space" ( hyperspace) jump points of a newly discovered colonizable world, a closely guarded secret. When the religious secret police discover that he has false credentials and has entered their world under false pretenses, a frantic chase and flight ensues. He is captured in his hotel room. A high-ranking officer named Cherkassky tries to render Tallon harmless by erasing his memory of the jump data, using a device called a "brain brush". He thinks that he has succeeded, but Tallon is equipped with a gadget that can sequester certain memories. Cherkassky enjoys tormenting people, ...

Faster-than-light
Faster-than-light (superluminal or supercausal) travel and communication are the conjectural propagation of matter or information faster than the speed of light in vacuum (). The special theory of relativity implies that only particles with zero rest mass (i.e., photons) may travel ''at'' the speed of light, and that nothing may travel faster. Particles whose speed exceeds that of light ( tachyons) have been hypothesized, but their existence would violate causality and would imply time travel. The scientific consensus is that they do not exist. According to all observations and current scientific theories, matter travels at slower-than-light (subluminal) speed with respect to the locally distorted spacetime region. Speculative faster-than-light concepts include the Alcubierre drive, Krasnikov tubes, traversable wormholes, and quantum tunneling. Some of these proposals find loopholes around general relativity, such as by expanding or contracting space to make the object ...

Kummer Surface
In algebraic geometry, a Kummer quartic surface, first studied by , is an irreducible nodal surface of degree 4 in \mathbb^3 with the maximal possible number of 16 double points. Any such surface is the Kummer variety of the Jacobian variety of a smooth hyperelliptic curve of genus 2; i.e. a quotient of the Jacobian by the Kummer involution ''x'' ↦ −''x''. The Kummer involution has 16 fixed points: the 16 2-torsion point of the Jacobian, and they are the 16 singular points of the quartic surface. Resolving the 16 double points of the quotient of a (possibly nonalgebraic) torus by the Kummer involution gives a K3 surface with 16 disjoint rational curves; these K3 surfaces are also sometimes called Kummer surfaces. Other surfaces closely related to Kummer surfaces include Weddle surfaces, wave surfaces, and tetrahedroids. Geometry Singular quartic surfaces and the double plane model Let K\subset\mathbb^3 be a quartic surface with an ordinary double ...

Hyperspace
In science fiction, hyperspace (also known as nulspace, subspace, overspace, jumpspace and similar terms) is a concept relating to higher dimensions as well as parallel universes and a faster-than-light (FTL) method of interstellar travel. In its original meaning, the term ''hyperspace'' was simply a synonym for higher-dimensional space. This usage was most common in 19th-century textbooks and is still occasionally found in academic and popular science texts, for example, '' Hyperspace'' (1994).'''' Its science fiction usage originated in the magazine '' Amazing Stories Quarterly'' in 1931 and within several decades it became one of the most popular tropes of science fiction, popularized by its use in the works of authors such as Isaac Asimov and E. C. Tubb, and media franchises such as ''Star Wars''. One of the main reasons for the concept's popularity in science fiction is the impossibility of faster-than-light travel in ordinary '' physical space'', which hyperspace ...

Science Fiction

These concepts may include information technology and robotics, biological manipulations, space exploration, time travel, Parallel universes in fiction, parallel universes, and extraterrestrials in fiction, extraterrestrial life. The genre often explores human responses to the consequences of projected or imagined scientific advances. Science fiction is related to fantasy (together abbreviated wikt:SF&F, SF&F), Horror fiction, horror, and superhero fiction, and it contains many #Subgenres, subgenres. The genre's precise Definitions of science fiction, definition has long been disputed among authors, critics, scholars, and readers.

Sonar
Sonar (sound navigation and ranging or sonic navigation and ranging) is a technique that uses sound propagation (usually underwater, as in submarine navigation) to navigate, measure distances ( ranging), communicate with or detect objects on or under the surface of the water, such as other vessels. "Sonar" can refer to one of two types of technology: ''passive'' sonar means listening for the sound made by vessels; ''active'' sonar means emitting pulses of sounds and listening for echoes. Sonar may be used as a means of acoustic location and of measurement of the echo characteristics of "targets" in the water. Acoustic location in air was used before the introduction of radar. Sonar may also be used for robot navigation, and sodar (an upward-looking in-air sonar) is used for atmospheric investigations. The term ''sonar'' is also used for the equipment used to generate and receive the sound. The acoustic frequencies used in sonar systems vary from very low ( infrasonic) to e ...

Political Prisoner
A political prisoner is someone imprisoned for their political activity. The political offense is not always the official reason for the prisoner's detention. There is no internationally recognized legal definition of the concept, although numerous similar definitions have been proposed by various organizations and scholars, and there is a general consensus among scholars that "individuals have been sanctioned by legal systems and imprisoned by political regimes not for their violation of codified laws but for their thoughts and ideas that have fundamentally challenged existing power relations". The status of a political prisoner is generally awarded to individuals based on the declarations of non-governmental organizations like Amnesty International, on a case-by-case basis. While such statuses are often widely recognized by the international public, they are often rejected by individual governments accused of holding political prisoners, which tend to deny any bias in thei ...
