That they exist is a proof that American ideals are not the tawdry pretenses they are so often accused of being.
或许这类人的存在,正证明了美国式理想并非无可挑剔,或者说它也在经受着现实的折磨，“

B=0 There's going to be some temperature where B is equal to zero. In that case, your gas is going to look awfully like an ideal gas.
在某个温度,这时，实际气体的表现，十分接近理想气体,高于这一温度它是正的。

The highest probability now is going to be along the x-axis, so that means we're going to have a positive wave function every place where x is positive.
概率最高的地方是沿着ｘ轴，这意味着只要在ｘ,大于零的地方波函数都是正的。
-
So here's my attempt to make the question both a bit more precise, and a question that's an open question.
我正尝试,让这两个问题变得更准确,这是个开放性的问题

It is something, as he stresses, that can be evoked by symbols, by poetic symbols, and this he intends to do in his poetry.

This is not to say that what is going at Harvard with numerous resources that we do have here is not important.
这并不是说哈佛现在,正投入大量资源的方面不重要。

And so, there is an attractive force between the two of them, the positive and the negative.
因此这两个正负电荷间，存在一个吸引力。
-
This is called the normal distribution or the Gaussian distribution-- it's a continuous distribution.
这就是正态分布,也叫做高斯分布,这是一个连续分布
-
In some cases, the back of the head could be more expressive than the front, in which case this is your opportunity and I wish you luck.
有些时候,后脑勺确实比正脸更有表现力,这才是你们的机会,祝你们好运

This just illustrates how massive this computations are, how significant they are.
这正解释了这些计算指令是多么庞大，多么重要。

Finally, another thing that is important is that all the stories that are generated as a result of using Star Festival as a model are becoming communal story So people share what they create with Star Festival.
最后，另一件重要的事就是,通过使用“七夕“这一模型发掘的所有的,这些故事正成为共同的故事,人们将他们用“七夕“创造的东西与他人共享。
-
We have an image here of the reconstituted, repaired body of Orpheus whose gory, severed head had been sent down the swift Hebrus to the Lesbian shore. It's as if Milton can't let go of this most un-Christian attachment to the human body.
想到一个完整的被修复好了的俄耳甫斯的身体,他血淋淋的被割下来的头颅曾,被赫伯鲁河一路冲下去直到莱斯博斯岛，似乎弥尔顿放不开,这对人体的眷恋，而这与基督教教义正相反。
-
Some notion of being above yourself and thinking yourself more than a man with the implication that you are approaching some kind of divinity by being more than a man, and acting accordingly,which usually requires that you use violence to achieve what you want.
某种超越自我的信念,认为自己不只是凡人,这就暗示了,你正接近某种神灵,为此,通常需要使用暴力,来达成所愿
-
So we would say we have a positive phase here and a negative phase there.
我们可以说我们在这,有正相位而这有负相位。
-
For all of Yeats's reactionary moods, even for his indulgence in nostalgia here, he's not a nostalgic poet. And this poem I think shows us what I mean by that.
尽管他有保守的心态，此处也是沉浸在回忆中，但他不是个怀旧诗人,这首诗正表现这点。

Okay. Last thing: This course, as you may have noticed from our friends behind us, is being filmed as part of the Yale Open Courses Initiative.
好，最后一件事,你们可能已经留意到我们身后的人，这门课正被拍摄下来成为耶鲁开公开课的一部分。
-
So, basically any time we have a really high positive number of electron affinity, it means that that atom or ion really wants to gain another electron, and it will be very stable and happy if it does so.
因此，基本上无论什么时候,只要我们有一个很大的正的电子亲和能，这就意味着这个原子,或离子非常希望得到一个电子，如果它得到了，会变得更稳定更开心。
-
So that's just a little bit of a check for yourself, and it should make sense because what you're doing is you're calculating the difference between energy levels, so you just need to flip around which you put first to end up with a positive number here, and that's a little bit of a check that you can do what yourself.
所以你们总要确保括号，离得这项是正的，这是你们自己,可以做的检查，这事很有道理的，因为你们做的是计算能量差,所以你需要调整顺序来保证一个正数，这是你们自己可以做的检查。
-
So you don't want to put in a negative energy, that's not going to help you out, you need to put in positive energy to get an electron out of the system. So that's why you'll find binding energies are always negative, and ionization energies are always going to be positive, or you could look at the equation and see it from there as well.
因为这对电离没有帮助,你需要一个正的能量,使得电子脱离这个系统,这就是为什么你会发现,结合能总是负的而电离能总是正的,或者你们看这个方程也可以发现这一点。
-
So, if we look at the bottom here and the actual plot of the wave function, we see it starts high, very positive, 0 and it goes down 0 and it eventually hits zero, and goes through zero 0 and then becomes negative 0 and then never quite hits zero again, although it approaches zero.
我们看,这下面这是波函数，我们看到它开始很高，是正的，然后降低直到,然后它穿过，变成负的,最后接近,但没达到，在这个。
-
So, an electron has a charge of negative e, we've written here and the nucleus has a charge of positive e.
我们写在这，原子核带正e的电荷,我们看到作用力。
-
So that is one plus against one minus.
因此这是一正对一负。
-
So it's really neat to think that your counterparts 100 years ago right here at MIT could have been sitting in a class where they had Lewis as their lecturer, and he's putting forth these ideas -- these are actually his lecture notes, even though it wasn't even published yet, and giving this idea of Lewis structure, which is exactly what we keep using today in order to make a lot of these predictions.
因此会有很棒的感觉，当想一想一百年以前像你们一样,在这上学的同学可能正坐在教室里,听路易斯讲课，而他正在提出这些想法-,-而这些正是他的课堂讲义，尽管当时还没有发表，但已经给出了路易斯结构的思想，这正是我们直到今天都一直在用的,用它来做很多预测。
-
If the Ax and Ay, some are positive and some are negative, this is the way by which we have learned we should combine multiples of i.
如果 Ax 和 Ay 有正有负,这就要用到我们所学过的方法,将所有 i 的倍数加起来
-
So, for example, if we were looking at the actual wave function, we would say that these parts here have a positive amplitude, and in here we have a negative amplitude.
我们看，一个波函数,我们说，它这部分幅值，为正,这部分幅值为负，当我们看。
-
Here is a chart that just shows the positive energies, and you can see the various components, and then the negative energies and the net.
这是展示正能量的表格，你可以看到不同的成分，负能量和总能量。
-
It's quite spectacular because here in the 1890s we have the apex of the Western classical orchestra, this big, beautiful, powerful instrument.
它之所以雄壮因为在十九世纪九十年代,西方古典管风琴正处于顶峰,这是一种巨大,美丽,有力量的乐器
