which I just did there, -mystring in fact, let me type it in-- mystring, with an equal sign, which is saying, assign or bind to that name the value of the following expression.

No, we can't. Because if l equals 1, we can not have m sub l equal negative 2, right, because the magnetic quantum number only goes from negative l to positive l here.
不行，因为如果ｌ等于１,ｍｌ的值不可能等于－２，对吧，因为磁量子数的值,这时只能从－１到１

So, sometimes people get confused when they're solving problems and call the amplitude this distance all the way from the max to the min but it's only half of that because we're only going back to the average level.
解题的时候会弄错，把这个从,最大值到最小值的距离,叫做幅值，但实际上,只有它的一半,只是它和平均值的差距。

In that case point p 1 doesn't correspond to this point, it actually corresponds to the point of radius 2 and angle 1, which is about here.

-
And when we talk about l it is a quantum number, so because it's a quantum number, we know that it can only have discreet values, it can't just be any value we want, it's very specific values.
当我们讲，l是一个量子数时，因为它是量子数，我们知道，它只能去分立的值，它不能取到所有的数，它取一些确定的数。
-
Meaning, why in the world do I have to tell the reader that I'm binding x to the value three? All right?
意思就是，我为什么要,告诉代码阅读者,要把x绑定到3这个值上呢？，对不对？

So, it would be a good question to ask n why are we limited clearly there's this relationship between l and n, and we can't get any higher than n equals one.
那我们要问了,为什么我们被限制了，很明显，l和,有关系，为什么不能取到，n-1更大的值。
-
This should make sense to you, because they don't, in fact, want to gain another electron, because that would mean that electron would have to go into a new value of n, a new shell, and that's really going to increase the energy of the system.
这对大家来说应该容易理解，因为它们实际上不想得到另一个电子，因为这意味着这个电子不得不,到一个新的，n，值更大的壳层上去，这将会增加系统的能量。
-
When we have n observations it's just the summation i = 1 to n of 2/n.
