It is structured and ordered into a few basic regime types. In this I take it to be one of the most important propositions and ? insights of political science. Right? So far?

So what we want to do now is to begin to think about counting measures, and we're going to do this by staying with this piece of Louis Armstrong here, and we need to be able to count measures so that we can figure out the syntax of music.

On the other hand, if the value I'm looking for here- sorry, the value I'm looking for is smaller than the value I see here, I just need to look here. All right?
如果我的目标数比这个值要小呢？,我就在这边找就对了，对不对？,做完了这一步,我可以在下一步做相同的操作，假设我选中了这一分支？
-
You can go ahead and use that equation, or you could figure it out every time, because if you know the total number of nodes, and you know the angular node number, then you know how many nodes you're going to have left.
你们可以直接用这个方程，或者每次都自己算出来，因为如果你们知道了总的节点数，又知道角向节点数，就知道剩下的节点数是多少。

-
Maybe not. It has no protons, so therefore, it has no electrons Because proton number equals electron number, which means if it has no protons 0 its atomic number is zero.
也可能不会，这个元素没有质子，因此，也没有电子,因为质子数等于电子数，意味着它没有质子,它的原子序数为。
-
You know you're a nerd if--so 16 of those ones will give you that particular number.

- The same place is that energy is a function of these four quantum numbers.
它就是这个结论,能量是这四个量子数的机能显示。
-
Just take a look: if this is 9, 5 divided by 9 is always going to be 0 point something, and if you thus have two integers and you're rounding down, which is what happens when you do integral math we're using this operator, I'm going to get zero times whatever.
稍微看一看：如果这是9，5除以9会得到,0点几，如果你用两个整型数,你舍去小数，这就是当你们,用整型数使用这个操作的所发生的事情，我将得到数值0乘以任何一个数字。
