Characteristics of vorticity in Belousov-Zhabotinsky (BZ) reactive-diffusive dynamics. Left: sketch28 of the temporal evolution from an instability that generates a spiral flow in diffusion until reaching a disordered structure also called phase turbulence. Middle: Zooming one of the spirals in the BZ experiment (the BZ background image was provided by Dr. M. Hauser from Von Guericke University (Magdeburg, Germany)). Right: Binary image of the highlighted spiral identifying its property of bilateral asymmetry. In the inset at the top left, by comparison, the pattern known as target is shown, which is completely bilaterally symmetric (that is, in relation to the vertical and horizontal axes, taking the center of the pattern as the intersection).
