Shapes: Nature's patterns: a tapestry in three parts

Patterns are everywhere in nature--in the ranks of clouds in the sky, the stripes of an angelfish, the arrangement of petals in flowers. Where does this order and regularity come from? As Philip Ball reveals in Nature's Patterns: A Tapestry in Three Parts, this order creates itself. The patterns we see come from self-organization. Indeed, scientists have found that there is a pattern-forming tendency inherent in the basic structure and processes of nature, whether living or non-living, so that from a few simple themes, and the repetition of simple rules, endless beautiful variations can arise.
