butterfly (n.)

鳞翅目昆虫的俗称, 在日光下活动, 古英语 buttorfleoge, 显然是 butter (n.) + fly (n.), 但这个名字的含义不明显. 也许是基于古老的概念, 即昆虫(或者, 根据格林姆的说法, 女巫伪装成蝴蝶) 食用未被覆盖的黄油或牛奶. 或者, 不太有创意的是, 仅仅因为许多物种的翅膀的淡黄色暗示了黄油的颜色. 另一种理论将其与昆虫排泄物的颜色联系起来, 基于荷兰的同源 boterschijte. 另见 papillon.

从17世纪开始应用于人, 最初是指虚荣和艳丽的装束, 到1806年是指从早期的低级状态转化而来的, 到1873年是指飘忽不定的倾向. 从1935年开始, 游泳的行程如此称呼. 作为机械螺母的一种, 1869年. Butterflies “焦虑引起的轻微胃痉挛” 出自1908年. “谁在轮子上打破了一只蝴蝶?” 出自波普.

The butterfly effect is a deceptively simple insight extracted from a complex modern field. As a low-profile assistant professor in MIT's department of meteorology in 1961, [Edward] Lorenz created an early computer program to simulate weather. One day he changed one of a dozen numbers representing atmospheric conditions, from. 506127 to. 506. That tiny alteration utterly transformed his long-term forecast, a point Lorenz amplified in his 1972 paper, “Predictability: Does the Flap of a Butterfly's Wings in Brazil Set Off a Tornado in Texas?” [Peter Dizikes, “The Meaning of the Butterfly,” The Boston Globe, June 8, 2008]
