Lesson 14-2     The Butterfly Effect

Suppose every

sensor gives perfectly accurate readings of temperature, pressure, humidity,

and any other quantity a meteorologist would want. Precisely at noon an

infinitely powerful computer takes all the data and calculates what will happen

at each point at 12：01, then 12：02, then 12：03...

The computer willstill be unable to predict whether Princeton, New Jersey, will have sun or rainon a day one month away. At noon the spaces between the sensors will hidefluctuations that the computer will not know about, tiny deviations from theaverage. By 12.01, those fluctuations will already have created small errorsone foot away. Soon the errors will have multiplied to the ten-foot scale, andso on up to the size of the globe.
