We're all out here trying to work hard and trying to clean up this mess."

This is what I'm supposed to tell you guys and we're all here to help you out.
我应该告诉你的就是这一点,我们在这的目的就是为了帮你们解决问题。
-
we're all living around here, so we all see each other every day.
我们都住在这附近，所以每天都能彼此见到。
-
We want to be loved for our hard work, and we're all working really hard here.
我们想因为努力工作受到喜爱，我们因此工作的很卖力。
-
All right, so we're into bribing you as we go along here, and all right?
好，因此我们会在,我们课程进行的途中一直收买你们，怎么样？
-
Just to illustrate the kind of issues that we're up against here, let me just consider a few different chemical reactions, all of which happen spontaneously.
为了说明我们的观点,考虑一些，不同的化学反应，这些化学反应都是自发进行的。
-
And finally we have Planck's constant here, which we're all familiar with.
最后这个是我们，都很熟悉的普朗克常数。
-
If you collapse data, as we did in this one paper, across all developed and developing countries here's what we're expecting in the next twenty-five years.
如果想改变这个情况,就像这页幻灯片中指出的,改变所有发达国家和发展中国家,对未来二十五年的情况的预期
-
As far as I know we're getting him, so I hope that you will all be able to come this Friday, here, at the usual time.
我知道他一定会来,所以我希望你们周五也能来,老时间,老地点
-
All we're going to do here is really just, once again, scratch the surface.
我们在这里只是，肤浅地解析一下。
-
We're going to use all of the pitches, all twelve here.
以后我们会用到所有的音高,共十二个
-
But yeah we're all excited to have you here and we have all sorts of things planned outside of problem sets and we have the Fair and everything that David has been talking about so we're really excited to start so.
我很高兴大家能来到这儿,除了习题集外我们还会遇到各种各样的问题,还有刚才David说过的,研讨会和其他东西,这门课开始了，我们真的觉得很高兴。
-
Let's see how these play out by means of a quick review of Beethoven's Fifth Symphony so all we're going to do here is going to go from the beginning of the track for the first movement to the second movement and so on, and well, let's just start here.
让我们通过迅速回顾贝多芬的第五交响曲,看乐章是如何表现的,我们现在要从,乐曲的第一乐章开头开始,听到第二乐章,以此类推,好,让我们从这开始
-
So, in terms of finishing our Lewis structure, we're actually not done yet here, even though we have full octets, and we've used up all of our valence electrons, and the reason is because it's c n minus, so we need to make sure that that's reflected in our Lewis structure, so let's put it in brackets here, and put a minus 1.
那么，根据我们的路易斯结构的完成情况，我们实际上还没有全部完成，尽管我们有了填满的“八隅体“,而且用完了所有的价电子，原因就是因为这是一个负离子，我们需要确保我们的路易斯结构能反映出这一点，所以让我们给它加个括号，再加个负一。
-
As a consequence, we believe that no student here is under-qualified for this course: you're all MIT students, you're all qualified to be here.
因此，我们相信这儿,没有学生是不够格的：,你们都是MIT的学生，你们都具备了相当的水准才能进来。
-
Wow, I think we're alright -something needs more regulation here -all these wires.
没弄坏什么吧,我们这里也需要更多监管,地上好多线
-
So all we're doing here is the most quick and superficial glance.
所以对它们我现在只做一个,最简单,最浅层次的分析
-
Remember, because that 1 s orbital is all the way down in terms of if we're thinking about an energy diagram, we're all the way down here, so we have a huge amount of energy we have to put into the system in order to eject an electron.
还记得吧，因为1，s，轨道在能量示意图里,是在最底部的，我们要一直到最下面，所以我们要向这个系统注入非常大的能量,才能打出一个电子。
-
So, essentially when we're talking about these equations up here, all we're doing is talking about the regular Rydberg formulas, but instead we could go back and re-derive the equation for any one electron atom, which would just mean that we put that z squared term in the front.
所以本质上,当我们讨论，这些问题时，我们说的是常规的，Rydberg公式，但对任何其他单电子原子，我们不用,从头再推到，而是仅仅把，z平方项放在前面。
-
So essentially, each of these orbitals come from linear combinations of all of the original orbitals, and it's hard to picture exactly how that happens, but one that you can at least start to get an idea is if you think about combining the 2 s and the 2 p z here, which is not quite accurate because of course, we're combining all of them.
本质上，这些轨道每个都来,自原来所有轨道的线性组合，我们很难想象这是怎么发生的，但你们可以至少有个概念,如果你们考虑2s和2pz轨道的结合，这当然是不太准确的，因为我们要把所有的都组合起来。
