Concepts of deterministic chaos were developed for low-order maps (the logistic map) and low order sets of equations (the Lorenz equations). Concepts of self-organized criticality evolved from large-scale simulations, i.e. the sand-pile model and the forest-fire model (both stochastic). Slider-block models bridge the gap between the two concepts. Two slider blocks exhibit classical deterministic chaos. Large numbers of slider blocks exhibit self-organized criticality. This behavior will be explained in terms of a turbulent-like cascade.
