The idea behind all these algorithms is that what's ultimately important is how many comparisons you ultimately need to make.
这些算法的思想是,你最终需要做多少次的比较,这才是真正重要的。

There are some exceptions, which we'll get to later, but the only a big exception here is with hydrogen, which has a special stability that's associated with two electrons.
但也有一些例外我们将以后再讲，但这里只有一个较大的例外，氢，它的稳定性比较特殊，只需要两个电子。

So it makes sense to be able to say, look for many methods I do want to have a way of doing comparison, and I don't have to remember, at top level, what the name of the comparison method was.
所有我需要的对象进行操作，那么就可以这么说了,我想要在很多方法里面，去找做比较的方法，我并不需要记住，每一个比较的方法的名字。

Okay, first of all, because everything relies on self-report there's no machine, for the most part, that can do objective measures of this, you don't really know when people are telling you what they're eating.
好,首先,因为任何事都是建立在自觉上,大多数环节没有机器参与,这样的方式比较主观,你并不需要,人们告诉你他们所吃的是否真实

What do I now need to do in order to sort the whole left half? Compare them all.

-
So at the end of the day we're not gonna get out of this need to compare, at least in this context of cups that have weights or ints that have values.
最终我们也无法改变要进行比较的需要,至少在有重量的杯子或者,整数的情况下是这样的。

I still have to do this process and here is where the finger thing gets a little more useful 'cause I have longer lists.

-
So, what this lets us do now is directly compare, for example, the strength of a bond in terms of a hydrogen atom and hydrogen molecule, compared to any kind of molecule that we want to graph on top of it.
因此，这让我们现在可以做到直接进行比较，比如，将一个氢原子，和一个氢分子的键的强度，与任何其它类型的分子进行比较,我们只需要把它的曲线也画在这幅图上。
-
Selection sort too really reduces to a total number of comparisons because I'm again comparing the current smallest to the next thing I see, the next thing, so really a lot of these sorting algorithms boil down to comparisons and the numbers that you actually have to make.
选择排序也可归纳为总数的比较,因为要将当前最小者与下一个进行比较,接着再下一个，可见,很多排序算法都可归结为比较,以及需要比较的次数。
-
Alright, now you kinda need to compare them all, right?
需要对所有的进行比较，对吗？
-
It took me seven comparisons, because I can take advantage of the fact I know I only ever have to look at the first element of each sub-list. Those are the only things I need to compare, and when I run out of one list, I just add the rest of the list in.
进行了7次对比，因为我可以利用我知道的优势：,每次只需要比较每个子列表的第一个元素,那才是我需要进行对比的内容,当一个列表的元素处理完了,只需要将另一个列表剩下的元素直接添加进去。
-
But we could, for example, look at a case where we have several different structures that look pretty good, and the one we want to determine as being the lowest energy structure is the one in which the absolute values of the formal charges are going to be lower, so essentially that they have less charge separation.
但是我们可能，比如，遇到一种情况,有好几个候选的路易斯结构看起来都挺好的，这时候我们就需要,通过比较哪个形式电荷的绝对值更低,来决定哪个结构的能量更低，本质上这个结构中分开的电荷更少。
-
And when we make these comparisons, one thing I want to point out is that we need to keep the constant principle quantum number constant, so we're talking about a certain state, so we could talk about the n equals 2 state, or the n equals 3 state.
当我们做这些比较时，我想指出的一件事是,我们需要保持常量原则,保持量子数是常数，所以我们在讨论一个确定的态时，我们可以谈论n等于2的态，或者n等于3的态。
-
I was just finding very tunnel vision-like, the smallest elements at that moment in time which means I don't know anything about the other elements other than they are not the smallest and so no matter what with Selection Sort I had to repeat this again and again and again and if you do out the math it's roughly N squared steps in the worst case as well.
我只有一个狭窄的视野，只知道某时刻的最小元素,就意味着我并不知道其他元素的任何情况,只知道它们不是最小的,所以不管怎样，在选择排序中,我就得一遍一遍地重复选择过程,在最坏情况下,大概需要N的平方次比较。
