所谓“蝴蝶效应”,用来比喻因果关系的复杂性。说的是南美洲的一只蝴蝶扇动翅膀,沿着因果关系的链条发展,最终引起北半球的一场风暴。蝴蝶翅膀扇起风暴,也许有些夸张,但是生活中的确有这样的现象,一件小事,引起连锁反应,波及越来越大,产生没有预见到的结果。某市公交公司去年实行了一个改革,在市内主要公交线路的电汽车上实行无人售票——即每车只有一名司机,乘客从前门上车,把钱或车票(一律五角)投入司机面前的一个封闭铁盒内,下车走后门。这是国际都市通行的方式,别的国家已经这样做了多少年,没有问题。不过在我国有一个问题——五角钱,无论是硬币还是 The so-called “butterfly effect” is used to describe the complexity of causality.
