"Chain Reaction" is a song by American singer Diana Ross, released on November 12, 1985 by RCA and Capitol, as the second single from her sixteenth studio album, Eaten Alive (1985). The song was written by the Bee Gees and contains additional vocals from Barry Gibb. Sonically, "Chain Reaction" is an R&B and dance-pop song.
Chicago Pile-1 (CP-1) was the world's first artificial nuclear reactor.On 2 December 1942, the first human-made self-sustaining nuclear chain reaction was initiated in CP-1 during an experiment led by Enrico Fermi.
This is then a self-propagating and thus self-sustaining chain reaction. This is the principle for nuclear reactors and atomic bombs. Demonstration of a self-sustaining nuclear chain reaction was accomplished by Enrico Fermi and others, in the successful operation of Chicago Pile-1, the first artificial nuclear reactor, in late 1942.
Chain reactions naturally give rise to reaction rates that grow (or shrink) exponentially, whereas a nuclear power reactor needs to be able to hold the reaction rate reasonably constant. To maintain this control, the chain reaction criticality must have a slow enough time scale to permit intervention by additional effects (e.g., mechanical ...
Frisch and Peierls then considered the speed of a uranium fission chain reaction, exponential in nature, where "τ is the time required for the neutron density to multiply by a factor e." The available data was very approximate, but their central point – that a bomb was possible using fast (~2 MeV) neutrons – remains.
Hans von Halban, Frédéric Joliot-Curie and Lew Kowarski demonstrated that uranium bombarded by neutrons emitted more neutrons than it absorbed, suggesting the possibility of a nuclear chain reaction. [124] Fermi and Anderson did so too a few weeks later.

Chain-reaction crashes can also occur in conditions of good visibility, when black ice or other road hazards are encountered unexpectedly as drivers round a curve or crest a hill. [ 1 ] Multiple vehicle collisions can also occur when a third vehicle is too close to an initial collision to avoid hitting one or both of the vehicles.
