然后看接下来的内容,接下来说的是如果这个字符串的长度等于，那么我就成功了。
-
And what he said was that when you get down to atomic length scales there are limits, there are constraints on our ability to observe.
讲的就是,当你去进入到原子长度的尺度中,我们的观察能力,有一定的限制条件。
-
So 1.1 times 10 to the -31 meters is not, in fact, a significant number when we're comparing it, for example, to the length of a ball, or the size of the baseball field.
所以1，1乘以10的负31次方米，事实上并不是一个很重要的数字，举例来说，当它与一个球的长度，或者一块棒球场地对比时。
-
Well, again, just as I said verbally a moment ago, if you're going here, you're literally touching, trying to read or change memory that's beyond the boundaries of a chunk of memory that you're supposed to be touching based on its length.
嗯，再次强调，就像我刚才说的，如果你从这里出发，你将依次接触到，试着读取或者改变内存,如果超出了你可以使用的,内存块长度的界限。
-
The force, as this weight drops is constant, mgh and so the work is just going to be m g h, h where this is h.
当重物掉落时候的力是恒定的，因此做功就是，这段长度是。
-
We talked about the inevitability of death; we talked about the variability, that people have different lengths of time before they die.
我们讨论过了死亡的不可避免性;,我们讨论过了其可变性，不同的人在他们死之前有所的时间长度不同。
-
Now, of course, we've got to have units and the units for lengths are going to be meters.
当然,这里还得有单位,长度的单位是"米"
-
Similarly, just as we have symbols for the presence of sound and its length, we have symbols that represent the absence of sound.
类似的,既然我们有符号,来表示声音的频率和长度,我们也有表示静音的符号
-
So if I had drawn that better it would look as if this was half of this distance, but I didn't draw it well.
如果我画得准确的话,这段应该是整段长度的一半,不过我没画好
-
That got split in half, and that got split in half until I got to a list of one.
在那里被分成两半，然后在那里被分两半,直到得到长度为一的列表。
-
Let me cluster them because really what I have, sorry, separate them out. I've gone from one problem size eight down to eight problems of size one.
让我把它们聚集起来，因为已经得到我想要的，抱歉，把它们分开来,现在我从一个长度为8的问题,得到了八个长度为1的问题。
-
So, when we think about a bond length, this is going to be the length of our bond here, that makes sense because it's going to want to be at that distance that minimizes the energy.
因此，当我们考虑一个键的长度的时候，这就应该是我们的键长，这是合理的,因为体系会在核间距达到这一距离时,能量到达最小值。
-
A magnitude is how long this guy is and direction is at what angle it is.
大小是指它的长度,而方向是指它与坐标轴的夹角
-
At atomic length scale, limits on our ability to observe.
在原子长度问题上，我们的观察受限。
-
Even though there's four bytes the length of the string is consistent with what a human being would interpret as the length 3 of the string which is 3.
即使那里有4个字节,字符串的长度,与我们所认为的长度是一致的,字符串的长度是。
-
And you can vary the width and the speed and the length.
你能改变它们的广度,速度和长度
-
And if I'm walking down the list, this is probably order of the length of the list s because I'm looking at each element once.
这可能大概就是数组的长度，因为我会遍历数组中的每个元素一次,现在你可能会想，等等，数组已经排好序了。
-
If I do this, try and get the 10th element of a list that's only eight long. I get what looks like an error, but it's actually throwing an exception.
如果我来这么做,试着去取长度为8的列表的第十个元素,我貌似能得到一个错误。
-
And we can also talk about the bond length, so we might be interested in what the bond length is, what the distance between these two nuclei are.
另外一点就是键长，我们对键的长度也感兴趣，也就是两个原子核之间的距离。
-
It's always good when we're looking for a wavelength that our answer is in a unit of length, that's a good sign already.
当我们计算波长时,如果答案是一个长度单位，那就是一个好的迹象。
-
As I keep moving down, that part gets smaller, it's not always the initial length of the list, and you're right. But if you do the sums, or if you want to think of it this way, if you think about this more generally, it's always on average at least the length of the list.
等等，随着移动，剩下的部分越来越小，并不是初始那么长了，如果你算一算，或者你这么想，你考虑更一般的情况，平均下来至少是列表的长度。
-
- And because I'm writing out a string that's the same length -- -- my strings aren't getting shorter -- it's creating this illusion of some animation.
因为我写了一个长度相同的字符串-,我的字符串不会变的更短-,它生成一个动画幻觉。
-
First, I'm going to do a sanity check strlen so we've used string length, strlen, before.
首先，我先做一个检查,我们以前使用过字符串长度函数。
-
Hmm. Well, wait a minute. If I want to sort a list, I'll take one element, I've got to look at probably a lot of the other elements in the list in order to decide where it goes. And that suggests it's going to depend on how long the list is.
我会取一个元素，然后去查看列表,来决定要把那个元素放到哪里,这就意味着它依赖于列表的长度,对，这没什么说服力，但是事实上。
-
There are some questions that might be a different length.
还有些问题,可能长度不同。
