If I had taken as my interpolation scheme, my white curve here, I could go to infinity and have the equivalent of absolute zero being at infinity, minus infinity.
要注意，如果我们采用，像图中白线这样的插值方案的话,我就可以一直降温下去,相应的绝对零度点。
-
I have no idea what's here at the moment so I'm just going to draw a question mark because that memory might have been used previously for some other purpose, but we know it's currently available to us so we have four bytes of memory.
我不知道在此刻这里是什么,所以我画一个问号，因为那块内存可能在之前,为其它的目的而使用过，但是我们知道它可以为我们所使用,这样我们就有4个字节的内存。

I am going to emphasize what you perhaps did anticipate that he would say, so that can take us along rather smoothly.

We just want to get a rough idea so we can tell me they need to have another 20 or they need to have another 100.
我们只是想得出个大概的数目,这样我们就可以告诉他们,是还需要20本还是100本。
-
We make inferences to the existence of things we can't see, when doing that helps us to explain something we can't otherwise explain.
我们推断一些看不到的事物的存在,因为这样做可以便于我们,解释某些我们不相信就无法解释的事情

OK. Once we've got that, we can certainly, though, do things like this.
好，一旦我们写好了，我们当然就可以实现这样的目的了。
-
Is this all okay? If we're all going to die then does it really mean that we should just do the best we can at anybody's expense while we're alive?
这样真的可以吗,如果我们终难免一死,这就意味着我们可以在活着的时候,可以不惜代价,去更好的满足自己吗

We could do this and we'd have the "Waltz of the Bulldog."
我们可以这样,这就成了,斗牛犬华尔兹
-
As long as we understand that, we can do this cancellation and this says on the left-hand side the change in the quantity v square over 2 is a times the change in the quantity x.
只要我们明白这一点,我们就可以这样做简化,在等号左边,v^/2的变化量,为a乘以x的变化量
-
So if we have a third, we can just introduce it like this and so things start to line up a lot more nicely.
所以如果我们有第三个，我们可以像这样引进它,这样代码就排得漂亮多了。
-
So I can now proceed to print it, change it, manipulate it, or what now.
这样我们就可以打印出来，或改变其值，对它进行操作，等等。
-
So we've tagged each of your numbers to your actual recitation, so we can see today which recitation actually is going to be doing the best in terms of clicker questions, who's going to get the most correct today.
我们已经将你们的学号,与你们参加的习题讨论小组关联起来了，这样通过回答选择题,我们就可以来比一比，哪个小组答对的人最多。
-
In other words, we choose a convention for the zero of entropy, so that then we can write entropies of products and reactants always referring to the same standard state.
换句话说，我们选择了一个,焓零点的约定，这样我们,就可以总是相对于同样的标准,状态写出生成物和反应物的焓。
-
So I put the electron configurations and actually drew it on an energy diagram here, so we can actually think about why this might be happening.
所以我写出了它们的电子排布,并画成了能级图的形式，这样我们就可以好好想一想,这个问题发生的原因。
-
OK. We're going to just try this one more time just so you can see it.
好的，我们将要再尝试一次,这样你们就可以看到它。
-
So now, this equation here relates three state functions together: the pressure the volume, and the temperature. Now, if you remember, we said that if you had a substance, if you knew the number of moles and two properties, you knew everything about the gas.
压强，体积和温度,大家应该还记得,我们提过，只要知道气体的摩尔数,和任意两个状态函数,就可以推导出其他的状态函数，这样，我们可以把它改写成。
-
if you don't want to use that, you can also derive it as we did every time, it should intuitively make sense how we got there. But the exams are pretty short, so we don't want you doing that every time, so we'll save the 2 minutes and give you the equations directly, but it's still important to know how to use them.
吸收的和发射的，如果你不想用公式,你也可以每次都向我们这样推导它,很直观的就能得到结果，但考试时间很短，我们不希望你们每次都推导,所以我们会直告诉你，让你节省2分钟，但知道如何应用它十分重要。
-
So it does that for us so that you can get away with just knowing the address of the first byte and it will make sure that you know when to stop by including the special value so, in fact, get the string if you type in a three-letter word, we allocate four bytes no matter what because we need an additional byte 0 for this special sentinel value back slash zero at the very end.
它为我们做了这些事情，这样我们就可以,通过第一个字节的地址,它还可以通过包含一个特殊的值,来保证在哪里停止，如果你输入了一个三个字母的单词,就可以获得那个字符串，不管怎样，我们分配四个字节,因为我们在末端需要一个额外的字节,来保存这个特殊的标志值--反斜杠。
-
That's a good thing, because I can them equal to each other.
这是件好事，这样我们就可以。
-
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。
