"So typically we report those positions, tell them what we see, that it could possibly be seaweed, and they can vector a surface asset to confirm."

OK, so we've got UV light here, and let's see what we can see, and we lose electrons, if that's what's happening.
好了,我们已经有了紫外光源,让我们来看看能观察到什么,如果那些事情发生了,我们将会失去电子。
So, what we can do is try using the classical description of the atom and see where this takes us.
用经典力学描述原子看看怎么样,我们要考虑的是一个,带正电的粒子和。
"The massive health care plans being crafted behind closed doors in Washington will ultimately allow the government to decide what doctors we can see, what treatments the government thinks you deserve, and what medicines you can receive,".

So we can see what it's doing is it runs. So let's try fib it here with Fib of 6.
我们可以看到它在,运行的时候做了什么,让我们试试。
"Maybe it would be nice if he (Obama) sees that he is working for the people, and he sees that the people are so drastically against a lot of his policies that maybe he might re-think it and say, 'Let's see what we can all work out together."

It's based on a confusion. Once we see the confusion, we can see what the answer to our question is.
是在混淆概念,一旦弄清了混淆的地方,这个问题就好回答了
So here's what we find, and as you can see there -is this bass rhythm moving slowly or quickly?
那么,大家能看到,这个低音节奏是缓慢还是迅速
So, I just want to write a few examples down with a few values for delta u or delta H or delta S, and see whether we can get any clues from what we see.
我先写一些例子,例子包含一些内能,自由焓和熵的变化数值,然后看从中,我们能不能得到一些启示。
And we talked about periodicity and properties, so let's go and take a look at what we have and see if we can reconcile this.
现在我们讲一下周期性,我们先看一下我们已经掌握的知识,看看能不能和我们要讲的达成一致。
We'll see what we can learn with them.
接下来咱看看从中我们学到了什么
I haven't figured out -maybe one of you has a suggestion, especially if we can get a -see what college he was here -we did it in his college because he graduated from Yale.
我还没考虑好,也许你们有好的建议,尤其是如果我们可以找到...,查查他原来是哪个学院的,我们在那个学院办,因为他就是耶鲁的毕业生
Yes, to me personally, I feel like it all depends on one's personal morals and like we can't sit here and just, like this is just my opinion, ... of course other people are going to disagree but Well we'll see, let's see what their disagreements are and then we'll see if they have reasons that can persuade you or not.
对,就我个人来讲,我觉得这完全取决于一个人的道德修养,而不是我们在这坐着说得清楚的,当然这只是我一家之言,其他人肯定会反对,但是,这个到时再说,先看他们的反对意见是什么,再来看他们的理由是否能说服你。
So if you've got putty or terminal up on the screen, -- and you're having some trouble that's really best seen with -- in that natural environment, we can actually see sort of tech-support style on the right-hand side what you're doing, and you can see everything we're doing.
所以如果你有Putty软件或者终端机在屏幕上,你遇到一些麻烦来显示最佳状态-,在那个自然环境中,我们可以看到很多,技术支持类型,在你们做的东西的右手边,你们可以看我我们在做的一切。
So, we can actually kind of visualize what we would see if we were looking at a photoelectron spectrum.
实际上,我们可以在一定程度上想象出,我们在光电子谱上可以看到什么。
Within the visible range of what we can see, you also want to know this relative order that's pretty easy -- most of us have memorized that in kindergarten, so that should be fine.
在可见光的范围内,你们要知道它们排列的,相对顺序,这非常简单,你们在幼儿园的时候。
And what he found here, which is what you can see and we can all see pretty clearly, is the slope of all of these lines is the same regardless of what the type of metal is.
他在这发现,你们也,可以很清楚的看到,不同金属直线的,斜率是相同的。
So in fact we can block this out and see what it does.
实际上我们可以画个简略图,来看看这是怎么实现的。
So that's what we want to load up with electrons, and then see if we can remove some.
所以那个是我们,想加载电子的地方,然后看看我们是否可以移动一点。
And what you can see directly from looking at this energy level diagram, is that the molecule that we have is now more stable in the individual atoms.
你从直接看,能级图中会发现,分子比单个的,原子能量更低。
So, we can think about trends in electron affinity just like we did for ionization energy, and what we see is a similar trend.
那么,我们可以想一想电子亲和能的,周期性规律是怎样的,就像我们刚才分析电离能那样。
So what we'll have here is a trigonal planar case, and you can see that we only have three electrons that are set for bonding, so we'll add three hydrogens, and for b h 3, we'll get a stable structure here.
让电子劲量远离的时候,不用考虑它,这个例子是平面三角形,你可以看到,只有3个电子可以成键。
So what you can see is again, we've got this ground state.
你们可以看到,这是基态。
So this isn't the most useful form that we can have, but what we'll see shortly is that from this, we can then derive further criteria for essentially any set of variables or any set of external constraints, like constant temperature or pressure or volume and so forth that we might set.
所以这不是我们所能得到的最有用的形式,但是我们会很快看到,我们能够进一步推导出包含任意变量,或者任意约束的自发过程判断标准,比如说恒定的温度,压强,体积或者其他我们能够给出的约束。
So let's look at another example, Li2 let's take lithium 2 and see what we can figure out here. In lithium 2, we have two atoms of lithium, each have three electrons in them.
让我们看另外一个例子,我们看一看,看我们能得到什么,在Li2中,我们有两个Li原子,每个带有3个电子。
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。
So here we have that graphed here, Z we have atomic number z graphed against ionization energy, so, let's fill in what the actual atoms are here, and we can see in general, yes, we're following the trend.
这就是我们要画的,横坐标是原子序数,纵坐标是电离能,让我们把真正的原子填上去,我们可以看出,总体来说,没错,满足规律。
And what you can see is we have this new constant that we haven't seen before.
你们可以看到,这个新的常数,这是我们以前没看过的。
And you can see, we will take this up next day and we will have a look at what the orbital shapes look like as a result of plotting this.
我们将在明天继续学习,我们将看到,绘制出的,轨道的形状。
We can see we have these low pitches, What did I just sing?
我们可以看到这些是沉音,我刚才唱了什么
