For the simple reason that the number of possible chess games is so huge, that computers can't calculate it.

原因很简单,棋局的潜在变数相当之大,以至于计算机根本无法将其完全计算出来

And an electron is something where, i n fact, we might be able to, if we calculate it and see how that works out, actually observe some of its wave-like properties.

如果我们对电子做计算,并且知道如何算出来的,那么我们是可以观测到,电子的一些波动性质的。

If we want to know the total heat added to the system, we can measure it, which is the straightforward thing, but sometimes you want to calculate in advance, or sometimes you want to calculate it on an exam.

如果想知道给系统的总热量，我们可以测量，这是很直接的事情，但有时候我们想事先计算它，或者需要在考试中计算。

So let's do a sample calculation now using this Rydberg formula, and we'll switch back to emission, and the reason that we'll do that is because it would be nice to actually approve what we just saw here and calculate the frequency of one of our lines in the wavelength of one of the lines we saw.

让我们用Rydberg公式,做一个例题，我们回到发射上,这么做是因为这样,可以用我们看到的波长,来验证我们计算的频率。
