So, one we finish our discussion of how we think about multi-electron atoms, we can go right on and start talking about these other things.
一旦我们结束了,多电子原子的讨论,我们马上就可以,开始讨论这些问题。
-
First we can do that by knowing the electron configuration, we can write it out just by going up the table here, up the energy levels.
首先我们知道了电子构型，我们可以从，能量最低处开始填。
-
So now that we begin to have this ability to express strings in memory, to understand what they are, we can start to apply actually real-world algorithms to them.
现在我们开始用这个技能来在内存中表达字符串,来理解它们是什么，我们可以开始,我们可以对其使用实际的，现实生活中的算法。
-
It's a process of undoing and undermining that really eats away at the argument, we could argue, throughout the entirety of Areopagitica.
这是个论点开始慢慢被侵蚀破坏的过程,我们可以争论这点，贯穿整个《论出版自由》中。
-
I thought that we'd begin then by turning to page 731, the left-hand column, the footnote.
现在我们可以开始了，翻到731页，看到左手边那一栏的脚注。
-
OK. If we do that, if you look at the handout then, I can now start implementing this.
好，我们开始做，你们可以看看课堂材料。
-
We can begin to see it is clear how Aristotle's best regime differs from Plato's intransigent demand for the rule of philosopher-kings.
我们可以开始清楚地发现,亚里士多德的最佳政体,如何有别于柏拉图,对哲学家国王统治的不妥协要求。
-
This piston is being brought out, so we expect 0 the work to be negative, negative. And we start o V2 ut with zero volume. We end up with a volume p2 of V2, and the external pressure is constant to p2.
所以我们可以想象功是负的,开始的时候体积是,最终的容积是,外界的压力恒为。
-
If people wanna kind of slide back, that's fine, as I'm talking Okay, we're ready.
各位要是现在想换到后排,就放心换,没关系的,我不介意,好,我们可以开始了
-
And let's work--we'll hear that again, but as you can see and then hold on that and then the changes came a little bit faster and faster.
我们开始吧，然后就可以再次听到了，不过就像大家可以看到，然后继续保持到,再开始有变化，变得越来越快。
-
In the early days when there are four or five formulas, you could memorize all of them and you can try each one of them until something works, but after a couple of weeks you will have a hundred formulas and you cannot memorize all of them.
刚开始我们只会涉及到四,五个公式,你可以全部记下来,你可以一个一个试,直到解出答案,但过了几个星期,你就已经学了一百多个公式了,你没法全部记下来
-
We had a good fortune to start it with a very top person in the GDMG, feeling it is a very important initiative within his organization.
我们运气很好,可以从GDMG的,一个顶尖人才开始研究，我们认为这一动机,是他的组织的原动力。
-
So, if we think about the bonds that are forming -- oh I see our TAs are here, so you can start handing them out, because we have two minutes left to go.
如果我们考虑所成的键-,我看到助教们都来了，你们可以开始发讲义了，我们还有两分钟就下课了。
-
So let's go ahead and introduce a couple other capabilities so that we can finally start writing programs that maybe print out charts or interact with the user, play games, or the like.
让我们继续来介绍其他几个功能,以便我们最终能开始写程序,那样可以打印图表或与用户交互，打游戏之类的。
-
OK, here we go, here we go, you see, I'm doing it down here, I can't see it, does that-- ah, I hear his sighs of relief, OK, good. There we go. Better. All right.
好，我们开始，大家可以看到，我在这里写这个程序，我看不见，这是不是-啊，我听到大家放松的叹气了，好，让我们开始吧，好多了，好。
-
So, if we start instead with talking about the energy levels, we can relate these to frequency, because we already said that frequency is related to, or it's equal to the initial energy level here minus the final energy level there over Planck's constant to get us to frequency.
如果我们从讨论能级开始，我们可以联系到频率上,因为我们说过频率和能量相关,或者说等于初始能量,减去末态能量除以普朗克常数。
-
So that's going to be the end of the exam 1 material, and then we'll move on to exam 2 material, which is kind of exciting, because we've been talking about just individual atoms and ions up to this point, and now we can talk about molecules, so we're going to start talking about bonding.
到此为止就是第一次考试的内容，接下来我们会开始讲第二次考试的内容，这些内容令人有点兴奋，因为我们一直都只是在讨论单个的原子,和离子到目前为止，而现在我们可以讨论分子了，要开始讨论成键的问题了。
-
In the aftermath of Darwin in particular, our understanding of natural selection, our understanding of genetic hard-wiring and other factors, makes us begin to wonder in what sense we can consider ourselves, each of us, to be autonomous subjects.
特别是继达尔文之后，我们对于自然选择，基因和其他因素的理解，让我们开始思考在哪种意义上我们每个人，可以把自己视为有自主性的主体。
-
We can start having complex expressions, you can imagine we can have things are lots of parens, and all sorts of things in it. Yes, question.
我们可以开始写复杂点的表达式了，你可以想象,我们有一个很多括号的表达式，里面有各种各样的东西，什么问题。
-
All right.Once we have them, we want to start making combinations out of them.
好，一旦有了这两个东西，我们就可以开始做他们的组合了。
-
And unlike n, l can start all the way down at 0, and it increases by integer value, so we go 1, 2, 3, and all the way up.
不像n，l可以从0开始取，然后每次增加一个整数，所以我们可以去1，2，3，一直下去。
-
I wanted to show you that, so, first thing I'm going to do is say, all right, I know I'm going to need square root in here, so I'm going to, in fact, import math.
我们可以开始完成这个方法了，我想让你们看到完成这个方法的过程，第一件事情就是,我们在这儿需要一个求平方根的方法，实际上我将引入math包。
-
All right, so now we can move on to the start of today's notes, which is atomic radius.
好，现在我们可以开始讨论今天的讲义了，从原子半径开始。
-
And then we can go ahead and let's quickly write out w hat the formal charges for all of these will be.
然后我们可以开始很快地,把所有的形式电荷都写出来。
-
So, you can imagine, that we'll actually probably have a lot of kinetic energy left over if we put a lot of energy in in the first place.
因此，可以想象，如果我们一开始,就注入大量的能量,那么得到的动能也应该很大。
-
So we can go ahead and think about, well, are there any other atoms that are going to have the same electron configuration?
那么我们可以开始想一想，好，有没有其它原子,具有相同的电子排布？
-
Now, once we've got that, we can start doing things.
好，我们可以开始做了。
-
We don't always want to go and solve the Schrodinger equation, and in fact, once we start talking about molecules, I can imagine none of you, as much as you love math or physics, want to be trying to solve this Schrodinger equation in that case either. So, what Lewis structures allow us to do is over 90% of the time be correct in terms of figuring out what the electron configuration is.
我们并不想每次都去解薛定谔方程，而且实际上，一旦我们开始讨论分子，我可以想象,你们中没有一个人，不管你有多么热爱数学或物理，会想去解这种情况下的薛定谔方程,总之，路易斯结构能让我们,有超过，90%，的概率判断出正确的,电子排布。
-
So, operands. Let us take expressions, get values out, we can store them away in places, but ultimately we want to do something with them, so we need to now start talking about what are the things we can do inside of Python, or any programming language, to manipulate them.
也就是运算对象，让我们看看这些表达式，然后看看里面的这些值，我们可以把他们存在计算机的任何位置中，最终目的还是要对这些值做一些操作，因此我们现在需要开始讨论,在Python里面可以做什么，来操作它们了，或者在任何编程语言里。
