Just a few reminders, if any of you are here for the first time, and I know there are a few, if you go to this particular website, and you can get to this from the classes server as well, you'll see the course website that we've developed and it has a lot more information than if you just go to the classes server and click on the syllabus.

提醒一句,如果有同学是第一次来听课,我看到了有些新面孔,你们可以登录这个网站,从课程服务器也能找到,你们会发现我们更新了课程网站,其中含有大量的信息,若你只访问课程服务器,点击教程大纲

So, we approached this machine here, the photograph is a little blurry, but it was very clear to us but if you zoom in on the screen and apologies for the reflections, again, this was just taken with my cell phone, you see what appear to be three huge buttons and at the top it said something like have a Charlie Card, which may very well apply to a lot of locals.

所以，我们走近这个机器，这个照片有点模糊，但对于我们来说是清楚地,如果我把它在屏幕上放大，我对这个影像感到抱歉,但是，这是用我的手机拍的,你们可以看到这里上面有三个很大的按钮,写了一些关于Charlie卡片的东西，对本地人来说是相当熟悉的。

So what I want to point out about them is that they're made up of two nodes, and what you can see is that nodes are shown in different colors here and those are different phases.

关于它们我要指出的是,它们有两个节点，你们可以看到在这里,这些节点的颜色不同，它们的相位不一样。

OK. Having done this now, I can simply go ahead and run this, and in fact if I go up here to run, you'll see I've got both an option to check the module, though in this case I'm just going to run it.

好，讲完了这些，我可以去执行程序了，实际上如果我在这里运行，你们会看到我同样得到了,一个可以同时检查模块的选项，虽然在这个例子中我就是直接去运行程序了。

So, if I kind of circle where the probability gets somewhat substantial here, you can see we're much closer to the nucleus at the s orbital than we are for the p, then when we are for the d.

我把概率,很大的地方圈出来，你们可以看到在ｓ轨道上,比ｐ轨道更接近原子核，最远是ｄ轨道。

It looks like we're still figuring out - this room was just renovated, we're still working out exactly how the electronics work. So normally we'll see a percentage of how many of you got it, but I'm going to say it was probably about 95% got the answer right.

这个房间刚刚装修过,我们还在试图搞明白，这些线路怎么工作的,如果正常的话,我们可以看到，你们回答正确的百分比，但我觉得你们,95%的人答对了。

I'm trying to get both decomposition the decomposition, right?

我将进行分解和抽象,你们可以看到分解对吧？

So this first little piece of code right here says, ok you give me 2 points, I'll create another 1 of these lists and I'll simply take the x, sorry I shouldn't say x, I'm going to assume it's the x, the x-values are the two points, add them together, just right there, the y-values, add them together and return that list.

好，为了来认识到这一点,让我们来看一个简单的小例子，在你们的课堂手册上，你可以看到我写了一个小程序,它假设我得到了，这些点中的一些，我想对它们做一些操作，例如我想把它们加到一起，那么这里的第一小片，代码的意思是，好给我两个点，我会再创建一个数组。

So I'm going to distinguish in fact between un-handled exceptions, which are the things that we saw there, and handled exceptions. I'm going to show you in a second how to handle them, but let's look at an example.

所以我打算区分开不可处理的异常,以及我们刚才看到的,可以处理的异常,我一会要给你们演示下如何处理他们,给你们看一个例子。

I'm going to give a name to that. And what you see there is I'm going to call divisors initially an empty tuple, something has nothing in it. Right here. And then I'm going to run through the same loop as before, going through this set of things, doing the check.

你们可以看到这里,我初始化一个空的元组,名为divisiors，这里，然后我会去运行,跟以前一样的循环，遍历这个集合内的东西,然后做检查，现在我要做的是，每次我找到了一个除数我要把它收集起来。

So if we do this and we form the molecule ammonia, let's switch to a clicker question, and have you tell me what the bond angle - is going to be in ammonia -- HNH Actually, let me draw it on the board as you look -- actually, can you put the class notes on, since you don't actually have your notes to refer to.

如果这样做的话，我们就可以形成氨分子，让我们来做一个课堂练习,你们告诉我氨分子中的键角是多少-,键角，the，h，n，h，bond，angle。,实际上让我在黑板上画出它来，这样你们可以看到实际上-,你能把课堂讲义放出来吗，因为你们没有讲义可以参考。
