After decades – indeed, centuries – of employing such tricks, physicists have forgotten that they are modeling phenomena, not necessarily uncovering Divine Truth. For instance, we can easily write down the equations for a ball on a swinging spring, but if we stretch the spring enough and swing the ball hard enough, we can’t solve those equations.
在连续几十年（事实上是几百年）运用这些伎俩之后，物理学家已经忘记了自己其实在模拟某些现象，而非发现绝对真理。比如我们可以轻易写出公式来描述一个悬挂在弹簧上的小球如何运动，但如果我们拉伸弹簧且晃动小球到一定程度，这些公式就失效了。整个运动变得一片混沌，根本无法得出一个精确的数学解释。
