Well, up to some level of accuracy, 6 yeah, that's 0.6 is what I'd like to get out.
好，在某个精确度上，答案是0。,这是我想要的答案。

All right, so you can't get perfect efficiency, 0 but at least if you were able to go to zero degrees Kelvin, then you'd be all set.
好吧，你得不到完美的效率，但至少如果能把温度降到,那你就万事俱备了。

You would minimize your losses; you'd get 0 or -1 instead of -3 or 1.
你能最小化你的损失,你得到0 -1而不是-3 1

putting all those things together, if you looked at this question again we'd get 100% on it, 0 9 that our only option here is 0. 9, and that it's not the negative, it's the positive version, because we're talking about how much energy we have to put into the system in order to eject an electron.
把这些放在一起，你们再看一下题目,大家100%都能选对，我们唯一的选择就是这个，它不是负数，它是正的，因为我们说的，是要,把电子激发出来,需要提供的能量。

So I could be 10 km from home, I could be 0 km from home, or I could be -10, if I'd gone two steps to the left.
我有可能距营地10公里,也可能是0公里,也可能是 -10,如果我两次都是向左的话

Again I should have said first, index 0, the first one. I can similarly go in and say I'd like all the things between index 2 and index 4. And again, remember what a b c that does. Index 2 says start a 0. 1, 2. So a, b, c.
我还是要说一遍，索引为0的元素，是第一个元素，我可以要求返回索引,2和4之前的所有元素，请记住2,是从0开始的,那么0，1，2对应的是。

> But if you actually do the math, those zeros and ones translate to an ASCII character which is D which is gonna be a 65, 66, 67, 68 would be the letter D.
>，你们自己算算看,把这些0和1转换成D对应的ASCII码,那么就是，65，66，67，68，对，68对应于“D“

If you could get to zero degrees Kelvin, you'd get perfect efficiency, 0 but you can't get to zero degrees Kelvin, you can't. Even if you have an infinite amount of resources, you can't get there.
如果能达到，你就能获得完美的效率，但你得不到，得不到，即使你有无穷多的资源,你也做不到。

What you need to know is that when m equals 0, 3dz2 it's 3 d z squared.
你们要知道的是,当m等于0时，它是。

Now I'll print L 2. Kind of what you'd guess, but here's the interesting question: if I say L 1 is assigned 0, L 1 sub is assigned 4, I'll print L 1.
然后我将显示下L2的内容，你，们猜猜这个有趣的问题：,如果我将L1赋值为4的话，再去显示下L1，会怎么样呢？
