摘要

The emergence of patterns is one of the world’s most durable mysteries. Some patterns (clouds, snowflakes) form in space, while others (the ebb and flow of tides, seasonal wet and dry spells) form in time. Do patterns such as the spirals in a frog egg, a fibrillating heart, and an ocean eddy have anything in common? The sizes are vastly different and the biology of a frog egg is far more complicated than the physics of a fluid. Yet the patterns formed in such systems, differing widely in scale and in the underlying mechanisms, can in some cases be understood from a common approach.
