Complexity: life at the edge of chaos

Complexity is the unifying theory of biological and physical phenomena. It holds that at the root of all complex systems lie a few simple rules, taking the notion of chaos (which states that within seemingly chaotic systems are elements of order) a step further by actually identifying these rules. The author sees it as the dominant scientific trend of the 1990s, as scientists from many disciplines come together and begin to discover the underlying similarities in their fields.
