We might be asked, for example, to determine what all of the different elements could be that would produce a spectrum that gave us 5 different lines.

那么我们会问，比如，有哪些不同的元素可以产生,一个有五条分立谱线的光谱？

And I want to suggest that what we've done is, we've outlined a lot of the basic elements of programming. A lot of the basic elements we're going to need to write code.

我想提醒大家我们学习的是，我们学习了很多关于,编程的基础的东西,一些我们编写代码需要的基础的东西。

And there's a lot we can explain by talking about what we see in the periodic table in terms of what different trends are in grouping different elements in different spots within the periodic table.

我们可以解释很多,通过讨论元素,周期表中的内容,按照各种不同的规律,将周期表中不同位置的元素分组归类。

And really constantly considering the story and what new twists and elements we need to add to the story are a pretty big deal for us as well.

不断反思这个故事,反思我们需要加进去的新情节和新元素,对我们来说也很重要。

So in your mind, if you are now the computer program and you are executing this thing from top to bottom, what just has happened verbally is we are stepping into the line of code that says sort left half of elements.

在你们看来，如果你现在是计算机程序,正在从上到下执行一系列指令，刚才所发生的就是我们现在已执行到了这行代码,它告诉你要对左半部分的元素排序。

What does it mean that both of these elements have been retained here side by side? What is the phrase? The whole is greater than the sum of the parts. So keep that awareness.

同时保持这两种意识是什么意思呢，哪句话可以,概括这一情况，应该是“整体大于部分之和“,所以请时刻记住这点。

If I went on and told you what the different incident light was, and what the electrons were ejected with, and then you could look up the ionization energy for the particular different elements, you should be able to actually determine exactly which element it is, but just with the information given, we can only narrow it down to these choices here.

如果我继续告诉大家入射光源是什么，出射电子的动能是多少，那么你可以去查一查,以上各个元素的电离能，这样你就应该能确定,这个元素到底是哪个，但是只凭题目中的信息，我们只能把范围缩小至以上几种元素。

So if we consider lithium, potassium, and sodium, they're all together in the same group on the periodic table, knowing what we do about biology we can immediately think of sodium and potassium, or even just knowing what you know about table salt, for example, that these are two elements that we find, and particularly in the ion form in very high concentrations in our body.

我们来考虑一下锂，钾和钠，它们都在周期表中的同一族里，想要知道我们将元素周期律,用到生物学会怎么样，我们首先想到的就是钠和钾，甚至只需要知道食盐，我们发现它们是以很高浓度的离子形式,存在于我们体内的两种元素。

Only later would a Yahweh only party polemicize against and seek to suppress certain what came to be seen as undesirable elements of Israelite-Judean religion, and these elements would be labeled Canaanite, as a part of a process of Israelite differentiation.

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。
