Fission \Fis"sion\, n. [L. fissio. See Fissure.]
A cleaving, splitting, or breaking up into parts.
(Biol.) A method of asexual reproduction among the lowest (unicellular) organisms by means of a process of self-division, consisting of gradual division or cleavage of the into two parts, each of which then becomes a separate and independent organisms; as when a cell in an animal or plant, or its germ, undergoes a spontaneous division, and the parts again subdivide. See Segmentation, and Cell division, under Division.
(Zo["o]l.) A process by which certain coral polyps, echinoderms, annelids, etc., spontaneously subdivide, each individual thus forming two or more new ones. See Strobilation.
(Physics) The act or process of disintegration of an atomic nucleus into two or more smaller pieces; called also nuclear fission. The process may be spontaneous or induced by capture of neutrons or other smaller nuclei, and usually proceeds with evolution of energy.
Douglas Harper's Etymology Dictionary
1819, "division of a cell or organism," from Latin fissionem (nominative fissio) "a breaking up, cleaving," from past participle stem of findere "to split" (see fissure). Cognate with Old English bitan "to bite." Nuclear physics sense is 1939. As a verb, from 1929.

- Mitochondrial fission
- Loop fission, a computer science concept
-
Nuclear fission, where a large atomic nucleus (such as that of uranium) is split into two (or sometimes more) smaller nuclei

Fission is a studio album by keyboardist Jens Johansson, released in 1997 through Heptagon Records (Europe); February 18, 1998 through Pony Canyon (Japan); and on March 24, 1998 through Shrapnel Records (United States). According to Johansson, the album went through an extremely troubled recording process due to several mishaps with Andy West's bass parts, which ultimately never made the album. On his website, Johansson also revealed that the indistinct image on the cover art is actually a heavily zoomed-in section of ice on a car window.
In biology, fission is the division of a single entity into two or more parts and the regeneration of those parts into separate entities resembling the original. The object experiencing fission is usually a cell, but the term may also refer to how organisms, bodies, populations, or species split into discrete parts. The fission may be binary fission, in which a single entity produces two parts, or multiple fission, in which a single entity produces multiple parts.
Fission is a Swedish melodic death metal band formed in 2002. The band began as Benny Hägglund's personal project, with the hopes of fusing melody and aggression into his music. After writing some material, he decided to seek aid from Andreas Hedlund of Vintersorg, the band in which Hägglund plays live session drums. After recording a two-track demo with Benny handling all instrumentation and Andreas handling vocal duties, they signed on with Austrian label, Napalm Records. Benny continued writing all of the songs for their first full-length, while Andreas provided all of the lyrics, vocals, keyboards, and sound effects. They released their first full-length album, Crater, on April 27, 2004.
