Turing pattern formation, autocatalysis, and biological spot/stripe emergence.

ACADEMIC & ALGORITHMIC REFERENCE

// HISTORICAL ORIGINS

Alan Turing published 'The Chemical Basis of Morphogenesis' in 1952, proposing that reaction and diffusion of two chemical morphogens explains animal coat patterns and organism development.

// GOVERNING EQUATIONS

\frac{\partial u}{\partial t} = D_u \nabla^2 u - u v^2 + F(1 - u), \quad \frac{\partial v}{\partial t} = D_v \nabla^2 v + u v^2 - (F + k) v

// BROWSER IMPLEMENTATION

Computes discrete 2D 5-point Laplacian spatial convolutions and nonlinear cubic reaction kinetics ( $u v^2$ ) across contiguous typed arrays.

🎯 Action:Select 'Mitosis Division' preset and drag across the canvas.

✨ Observe:Watch individual chemical spots grow, elongate, pinch in the middle, and divide into daughter cells.
