Critical Mass
In nuclear engineering, a critical mass is the smallest amount of fissile material needed for a sustained nuclear chain reaction. The critical mass of a fissionable material depends upon its nuclear properties (specifically, its nuclear fission cross-section), density, shape, enrichment, purity, temperature, and surroundings. The concept is important in nuclear weapon design. Explanation of criticality When a nuclear chain reaction in a mass of fissile material is self-sustaining, the mass is said to be in a ''critical'' state in which there is no increase or decrease in power, temperature, or neutron population. A numerical measure of a critical mass is dependent on the effective neutron multiplication factor , the average number of neutrons released per fission event that go on to cause another fission event rather than being absorbed or leaving the material. When ''k'' = 1, the mass is critical, and the chain reaction is self-sustaining. A ''subcritical'' mass is a ...

The bassist hasn’t exactly been relaxing in the meantime; he put out two albums of big-band music and toured extensively, and released a stellar double-live CD by his quintet. And all the while, the least grateful among us have been hankering for some new music from Holland’s quintet. Well, here it is, and it holds its own against Prime Directive, the group’s most impressive release... The groupthink mentality manifests itself most obviously on the New Orleans tribute “Easy ...
