When presenting his groundbreaking model of chaos and the potential of extreme chaotic unpredictability at the 1972 meeting, Lorenz posed the question: “Does the flap of a butterfly’s wings in Brazil set off a tornado in Texas ”
Richard ·A· Anthes, former president of the University Corporation, says Lorenz was illustrating how, “in a system of apparently simple mathematical equations (方程式), a tiny change in the initial position of the particle can cause huge changes in its future position.” This analogy, so simply and beautifully expressed with Lorenz’s fascinating metaphor (隐喻), captured the imaginations of scientists and the public alike.
The butterfly effect “disrupted science at a philosophical level, showing that modeling the future is only predictable to an extent”, explains Bo-Wen Shen, an associate professor at San Diego State University. Shen thinks this is because the idea that even the slightest changes may have significant impacts offers hope to individuals, encouraging them to take small actions that could have a profound and positive effect.
The concept has been the subject of films and social media where people shared their butterfly effect stories: seemingly random events — a car breaking down, a missed train, a broken shoe — that lead to significant moments in their life. These stories often misunderstand Lorenz’s original concept and more accurately describe a coincidence. The main disconnect lies in the belief that the ability of a tiny change to create an organized disturbance at large distances is a real phenomenon.
Tim Palmer, a climate physics professor at Oxford, argues that Lorenz’s butterfly effect illustrates how weather emerges from independent atmospheric patterns interacting in fleeting (闪现的), collective ways. In 2017, he said we could imagine weather like a set of Russian dolls: a large low-pressure system holds turbulent thunderstorms, which contain smaller clouds and eddies (漩涡), with even tinier eddies inside. His idea about how to understand the butterfly effect is “there are limited predictability horizons which cannot be extended by reducing uncertainty in initial conditions”.
Shen says the butterfly effect is best illustrated using this proverb-like folktale by poet George Herbert in 1640:
“For want of a nail, the shoe was lost.

（1）求做功冲程中燃气对活塞的平均压力；
（2）求燃气对活塞做一次功的大小；
（3）求汽油机在此工作状态下的功率；
（4）如果此工作状态下每分钟需消耗10 g汽油，那么汽油机把内能转化为机械能的效率是多少？（q汽油＝4．6×107 J/kg，不计摩擦）
单元练习题参考答案
1．【答案】A
【详解】2.4×103J/（kg ℃）、3.0×107J/kg，从这两个数据的单位可以看出：分别表示酒精的比热容、热值，故A符合题意，BCD不符合题意。
