Thermodynamicstalks about equilibrium systems and how to go from one state of equilibrium to another state of equilibrium.
热力学研究的是平衡系统,以及如何,从一个平衡态转变到另一个平衡态。
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。
It's part of a family of viruses, and we'll talk about at least one other member of that family of viruses as we go through here.
它是病毒家族的一员,我们将会讨论病毒家族的其他成员,至少要讨论一个
How about one more question and then we'll let you go?
还提一个问题,然后结束怎么样?
Notice if I'm going to have two different sub problems I need to have two base cases here to catch this. And if I only had one it would error out. And as a consequence, I can go off and ask about rabbits. Let's see.
我需要定义两个基础事件来处理它,如果我只有一个基础事件的话就会产生错误,这样我就能够知道到底有多少只兔子了,让我们来看看,在第12个月末,没那么简单,在第二年末兔子就很多了。
As I said the other day if that Confederate flag would just go away, just vanish, just stick it in the basement of museums and no one would ever care about it anymore, maybe, maybe the South's burden would go away.
正如我前段时间说过的,除非南北战争的邦联旗能够消失,被放进博物馆的地下室,再也没有任何人去关注它,那南方历史的阴影可能就真的不复存在了
And a lot of children I have come from different cultures, actually we cannot give them more insight into another culture, because even though they go to school with one and another, they don't know that much about each other's backgrounds, where they come from, or what part of world , what language they speak at home.
很多的孩子都是来自于,不同的文化,事实上我们给不了他们,对于其他文化的更多的见解,因为即使他们和其他的,孩子一起来上学,他们并不知道,其他人的背景,他们来自哪,或者世界的那部分,他们在家说什么语言。
Well a calorie technically--and this is again, not something that we would ever quiz you on but I just thought you might be interested to know-- that it's the energy required to raise one gram of water one degree centigrade, and we'll talk in a minute about you might go about measuring that.
理论上一卡路里,我重复下,这不是考试内容,但我想你们会感兴趣,一卡路里,是将一克水提升1℃所需要的热量,过会儿我们会讲如何测量
s very interesting if you go back and you read about al-Qaeda, one of the things that you read about is that Arabs, after World War Two saw the United States as standing for values of liberty and democracy and equality.
有一点很有趣,It’,如果你回头读读看看关于基地组织的报道,肯定不难发现,二战以后,阿拉伯人,将美国视为,自由,民主,平等的象征。
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。
If you think about what happens when we go from hydrogen to helium, now instead of one electron, we have to describe two electrons, so now we have six position variables that we need to plug into our Schrodinger equation.
如果你们考虑,当我们从氢到氦会发生些什么,现在我们不是要描述一个电子,我们将要描述两个电子,所有我们现在将有6个位置变量,需要加入至薛定谔方程。
