Rössler AttractorDrag to orbit, scroll to zoom. A hundred thousand specks follow three simple rules. They wind outward on a flat spiralling sheet, and each lap the outer edge peels up, folds over, and drops back to the middle — a taffy-pull that never repeats.In 1976 Otto Rössler, a chemist, stripped Lorenz’s weather model to the bone: only one of the three equations is nonlinear. The single stretch-and-fold it leaves is the minimal recipe for chaos, and the crease in the sheet is where nearby paths are torn apart.
