Editing Feigenbaum constants (section)

==History==
Feigenbaum originally related the first constant to the [[period-doubling bifurcation]]s in the [[logistic map]], but also showed it to hold for all [[one-dimensional]] [[map (mathematics)|maps]] with a single [[Quadratic function|quadratic]] [[Maxima and minima|maximum]]. As a consequence of this generality, every [[Chaos theory|chaotic system]] that corresponds to this description will bifurcate at the same rate. Feigenbaum made this discovery in 1975,<ref>{{cite journal |url=http://chaosbook.org/extras/mjf/LA-6816-PR.pdf |last=Feigenbaum |first=M.
