Sphere

A sphere (from Greek σφαῖρα — sphaira, "globe, ball") is a perfectly round geometrical object in three-dimensional space that is the surface of a completely round ball, (viz., analogous to a circular object in two dimensions). Like a circle, which geometrically is a two-dimensional object, a sphere is defined mathematically as the set of points that are all at the same distance r from a given point, but in three-dimensional space. This distance r is the radius of the ball, and the given point is the center of the mathematical ball. The longest straight line through the ball, connecting two points of the sphere, passes through the center and its length is thus twice the radius; it is a diameter of the ball.

While outside mathematics the terms "sphere" and "ball" are sometimes used interchangeably, in mathematics a distinction is made between the sphere (a two-dimensional closed surface embedded in three-dimensional Euclidean space) and the ball (a three-dimensional shape that includes the sphere as well as everything inside the sphere). The ball and the sphere share the same radius, diameter, and center.

Spheres (Pestilence album)

Spheres is the fourth album by the Dutch death metal band Pestilence, released in 1993. It was their final album before a 14-year hiatus from 1994 to 2008. On this album, the band experimented with a more progressive sound, utilizing guitar synthesizers as well as some jazz influences.

Mutant (album)

Mutant is the second studio album by Venezuelan electronic music producer Arca. It was released on November 20, 2015 via Mute.

Critical reception

Mutant received widespread critical acclaim from contemporary music critics. At Metacritic, which assigns a normalized rating out of 100 to reviews from mainstream critics, the album received an average score of 81, based on 21 reviews, which indicates "universal acclaim".

Mark Richardson of Pitchfork Media gave the album a very positive review, stating, "Compared to Xen, Mutant feels less composed and less indebted to classical music. With many tracks on the former album you could squint a little bit and imagine them being performed by a daring new music ensemble, à la Aphex Twin with Alarm Will Sound. But Mutant leans toward soundscape, avoiding proper songs." Richardson concludes, "On Mutant, Ghersi turns a fixation on porousness and instability into a kind of spiritual pursuit."

Writing for Exclaim!, Daryl Keating said Mutant "is an album that is eventually rewarding, but only to those who are determined to follow its scattered pathway to the satisfying, aggregate end."

Mutant (fictional)

The concept of a mutant is a common trope in comic books and science fiction. The new phenotypes that appear in fictional mutations generally go far beyond what is typically seen in biological mutants and often result in the mutated life form exhibiting superhuman abilities or qualities.

Gage Comics

In The Gage Team world, mutants are humans or other known species in the universe that, due to some experiment or other accident, have superhuman capabilities. These mutants are not called mutants, however. Unnaturals are mutants with ordinary superhuman powers, such as super-strength and super-speed. Super-Unnaturals are mutants that have the ability to change their form (Invisibility is considered an Unnatural power). Mutants that have received their powers from a Crystal are called Powerlings. Ultralings are mutants that have been received their powers from two Crystals.

Marvel Comics

In Marvel Comics, genetic mutation has been used as an explanation for super-powers since the 1950s. Mutants have played a major role in Marvel comics, particularly the X-Men and related series. In the Marvel Comics universe, they are a heavily persecuted minority. The Marvel Universe redefines the term to beings who are in a higher stage of evolution known as "Homo superior" and are not yet accepted by the human race.

Mutant (role-playing game)

Mutant is a series of Swedish role-playing games that were developed and published by Target Games.

1984 version

The campaign setting was very similar to Gamma World, taking place hundreds of years after a big catastrophe. The world is populated by humans, robots, and mutants (including anthropomorphic animals). The rule system was similar to the modified Basic Role-Playing rules used in Target Games earlier Drakar och Demoner game, utilizing a percentile die. In 1986 a rules expansion called Mutant 2 was published that among other things introduced a more advanced skillsystem, advanced rules for combat, hit locations and a more developed campaign setting.

1989 version

In 1989 Target Games introduced a new version of Mutant (unofficially branded "New Mutant" to distinguish it from the older version). In this version, it was the year 2089 and the world was ruled by large corporations in gigantic cities, like in Judge Dredd. This was the first cyberpunk role-playing game in Swedish. The rules were simpler compared to the ones introduced in Mutant 2.
