How do the concepts of scale, resilience, brittleness, and elegance, relate to complexity? The answers to these questions are—unfortunately—complex. In fact, the most difficult issue involved in answering these questions is deciding where to begin.
The best place to begin is at the beginning—in this case a few definitions of complexity, from “everything I don’t understand,” to “that which involves ...
