Of course the word chaos is used in rather a vague sense by a lot of writers, but in physics it means a particular phenomenon, namely that in a nonlinear system the outcome is often indefinitely, arbitrarily sensitive to tiny changes in the initial condition.

当然，“混沌”这个词在很多作家的作品中都有相当模糊的含义，但在物理学中，它指的是一种特殊的现象，即在非线性系统中，结果往往是不确定的，对初始条件的微小变化非常敏感。
