Governing equation

\overset{x}{˙} \overset{y}{˙} \overset{z}{˙} = σ (y - x) = 10 (y - x) = x (ρ - z) - y = x (28 - z) - y = x y - β z = x y - 2.667 z

Reading this result: Classic Lorenz (ρ=28, σ=10): the trajectory orbits two lobes forever without ever repeating. Sensitive dependence on initial conditions means the tiniest nudge changes everything — the butterfly effect.
