Lorenz Butterfly Attractor

The classic chaotic system that ushered in modern chaos theory and the term "butterfly effect."

Equations

dx/dt = σ (y − x)
dy/dt = x (ρ − z) − y
dz/dt = x y − β z

With parameters σ = 10, ρ = 28, β = 8⁄3 the system charts a pair of swirling wings. Tiny variations in starting point quickly diverge, illustrating sensitive dependence on initial conditions.
