从斑马身上的条纹到河床上的涟漪,自然系统中的模式比比皆是。在许多这样的系统中,有序状态的出现作为底层有序过程的结果并不是出乎意料的。因此,晶体生长、蜂窝制造和小花进化产生了规则和可预测的模式。本质上嘈杂和无序的过程,如热波动或机械随机散射产生惊人的相似模式。在这里,我们讨论一些被认为是这些相似性核心的潜在机制。
Patterns in natural systems abound, from the stripes on a zebra to ripples in a riverbed. In many of these systems, the appearance of an ordered state is not unexpected as the outcome of an underlying ordered process. Thus crystal growth, honeycomb manufacture and floret evolution generate regular and predictable patterns. Intrinsically noisy and disordered processes such as thermal fluctuations or mechanically randomized scattering generate surprisingly similar patterns. Here we discuss some of the underlying mechanisms believed to be at the heart of these similarities.
