Lesson 14-2 The Butterfly Effect
Suppose every sensor gives perfectly accurate readings oftemperature, pressure, humidity, and any other quantity a meteorologistwould want. Precisely at noon an infinitely powerful computer takes allthe data and calculates what will happen at each point at 12.01, then12.02, then 12.03..
The computer will still be unable to predict whether Princeton,New Jersey, will have sun or rain on a day one month away. At noon thespaces between the sensors will hide fluctuations that the computer willnot know about, tiny deviations from the average. By 12.01, thosefluctuations will already have created small errors one foot away. Soonthe errors will have multiplied to the ten- -foot scale, and so on up to thesize of the globe.

假设每个传感器都能准确地读出温度、压力、湿度和气象学家想要的任何其他数值。在正午时分，一台功能强大的计算机收集所有的数据,并计算出在每一点12.01、12.02、12.03时会发生什么。
计算机仍然无法预测普林斯顿新泽西州，将有太阳或雨的一天，一个月后。中午，传感器之间的空间将隐藏计算机不知道的波动，与平均值的微小偏差。到12点01分，那些波动已经在一英尺外造成了小错误。不久,误差就会成倍地增加到10英尺的范围，如此类推，一直扩大到整个地球的大小。
