Feigenbaum: quantitative universality in nonlinear transformations

What changed

Quantified universal scaling constants for a class of maps and introduced a renormalization fixed-point mechanism.

Scientific scope

The record is the sole-author 1978 Journal of Statistical Physics article. Earlier numerical observations, the sequel’s more exact theory, rigorous proofs and applications to particular physical systems remain separate.
