Nuclear Energy Nuclear energy is energy resulting from nuclear reactions or changes in the atomic nuclei. Example:Nuclear fission, nuclear fusion, andnuclear decayare examples of nuclear energy. An atomic detonation or power from a nuclear plant are also examples of this type of energy. Chemical E...
is between a microcomputer and mainframe computer (as related to size and power). The term "minicomputer" developed during the 1960s to describe computers that utilized transistor technology. During the 1970s and 1980s, the development of microcomputers—or desktops—placed minicomputers in the ...
each other and compound the magnitude of any disaster incident (United States Department of Homeland Security, Office of Inspector General2009). A prime example is the March 2011 Tohoku earthquake leading to a tsunami (natural) that triggered the Fukushima Daiichi nuclear disaster (man-made). Disas...
Like the vacuum tube, newer technologies offering better price/performance ratios have gained dominance and relegated mica technology to niche markets where uncommon stress factors such as nuclear radiation, extreme temperatures, or high voltage stresses justify the cost of a mica device. Figure 16: ...
Explosive, any substance or device that can be made to produce a volume of rapidly expanding gas in an extremely brief period. There are three fundamental types: mechanical, nuclear, and chemical. A mechanical explosive is one that depends on a physical

(These are seen only in spiral galaxies, most often near the arms.) Until this stage of its evolution, the star has shone by means of the nuclear energy released at and near its core in the process of squeezing and heating lighter elements such as hydrogen or helium into successively ...
. In the 1960s the nuclear-powered submarine, capable of remaining underwater for months at a time and of firing long-range nuclear missiles without surfacing, became an important strategic weapon platform. Armed with torpedoes as well as antiship and antisubmarine missiles, the nuclear attack ...
of gas from chemical explosives may be undesirable, but otherwise is very little used. Anuclear explosive is one in which asustainednuclear reactioncan be made to take place with almost instant rapidity, releasing large amounts of energy. Experimentation has been carried on with nuclear explosives...
