1. fission - Noun
2. fission - Verb
A cleaving, splitting, or breaking up into parts.
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.
A process by which certain coral polyps, echinoderms, annelids, etc., spontaneously subdivide, each individual thus forming two or more new ones. See Strobilation.
Source: Webster's dictionaryI must furnish those, who would protect or save life, with an energy source, which produces energy so cheaply that nuclear fission will not only be uneconomical, but ridiculous. This is the task I have set myself in what little life I have left. Viktor Schauberger
It was my responsibility that this world got itself an atom bomb, because there were only a handful of nuclear physicists in the thirties - only a handful. And we were all beating the desk and saying "How wonderful it will be if we discover atomic fission." L. Ron Hubbard
The fundamental point in fabricating a chain reacting machine is of course to see to it that each fission produces a certain number of neutrons and some of these neutrons will again produce fission. Enrico Fermi
France generates a significant part of its energy requirements from fission reactors and these have achieved a perfect safety record. We build ours all differently. Wilson Greatbatch
Nearly all of our existing power sources are generators which use a heat cycle. This includes our coal, oil, and gas fired utilities, our automobiles, trucks, and trains, and even our nuclear fission utility power plants. Wilson Greatbatch
In the current fashionable denigration of technology, it is easy to forget that nuclear fission is a natural process. If something as intricate as life can assemble by accident, we need not marvel at the fission reactor, a relatively simple contraption, doing likewise. James Lovelock
