STRUCTURE TRIGGER 1)2)
Some noise in a system that reveals a hidden potential order.
R. VALLÉE argues that noise cannot create order, but that it can make visible some implicit order. This is the case "when, because of a variation of some parameter defining the dynamics (of a system), it reaches a unstable equilibrium state, where a variation, even very small, of its state, produced by some environmental perturbation (i.e. a noise), throws it in one of the possible evolutive branches at that bifurcation point" (1992c).
This is consonant with the so-called order from noise principle, as examplified by von FOERSTER's box of disordered magnets, which however conceals potential order. It is also related to PRIGOGINE's nucleation.
