我们要解的就这个，所以我可以把这个写成矩阵。

That is what we want to solve. Well, I can put this into matrix form.

所以，我们可以像之前我们做的那样解这道题。

So then, we can do it the same way we did here.

在每一步上，我们都会发现比以前更好的技术可以让我们把代码从硬依赖中解耦出来。

At each step, we've found techniques better than the previous to let us decouple code from hard dependencies.

So, what we can do instead of talking about the ionization energy, z because that's one of our known quantities, so that we can find z effective.

我们做的事可以代替讨论电离能,因为那是我们知道的量子数之一，那是我们可以解出有效的，如果我们重新排列这个方程。

So always amazing to us how we go into the problem, our eye or mind can see one class of solutions, but the math will tell you sometimes there are new solutions and you've got to respect it and understand and interpret the unwanted solutions, and this is a simple example where you can follow what the meaning of the second solution is.

解决问题的方式总能让人惊喜不已,我们的眼睛或思想可以看见一类解,但数学有时会告诉你还有新的解,你不能忽视它,而是解释这些不期而至的解,这只是一个简单的例子,由此你可以理解第二个解的意义
