Primes¶
- Chaos
- the attractor is the climate regime (Lorenz attractor in the canonical reduction). Biology and ecology → the rule is the population dynamics (logistic, Lotka-Volterra, neural-firing equations); the state space is population-size or membrane-voltage space; sensitive dependence appears in high-reproduction populations
This sourceSeminal paper showing that the logistic recurrence x_{n+1}=r·x_n·(1−x_n) generates fixed points, period-doubling cascades, and chaos depending on r; demonstrates substrate-independent recurrence across ecology, economics, and physics.

- Nonlinearity
- Qualitative phenomena enabled: a stable equilibrium at `N = K`, monotone approach from any positive initial condition, and — when the same logic is extended to discrete time as the logistic map* `x_{n+1} = rx_n(1 − x_n)` — a period-doubling cascade leading to chaos for `r > 3.57…` (May 1976

- Recurrence
- The structural insight is robust: a Fibonacci population doubling, a sunspot cycle, an empire's rise-and-fall, neural signal propagation in feedback loops, and a chronic relapse cycle all exhibit the same recurrence logic: current state encodes history and influences futures—a unifying point May (1976) made starkly when he showed that the same one-line recurrence relation produces fixed points, oscillations, and chaos across ecology, economics, and physiology.
