Chemical Basis of Morphogenesis

Art | Parabolic | Patterns

This is the first page of Alan Turing’s The Chemical Basis of Morphogenesis paper undergoing pattern formation. The kinetics are exactly from the Schnakenberg example:

\[\begin{aligned}\pd{u}{t}&=\nabla^2 u+a-u+u^2v,\\ \pd{v}{t}&=D\nabla^2v+ b-u^2v,\end{aligned}\]

but we have taken an initial condition from an image of the first page of Turing’s text.
