So, it's Newtonian mechanics, and the reason for this is because Newtonian mechanics does not work on this very, very small size scale.
牛顿力学,因为牛顿力学,在这种很小的尺度下不适用,我们说过,牛顿力学。
So supposed that the list is not of size 8, let's make it slightly more interesting and double it.
假如列表的大小不是,为了更有趣,使其加倍。
Obviously the algorithm is likely to depend on the size of the input, so this is not a great idea.
很明显这个算法是与我的,输入的大小相关的,因此这不是个好方法。

Well they're not necessarily, because we only have the number three player in terms of size.
其实不是的,我们在规模上只能排到第三
The only thing that's different is that they're one down on the periodic table, potassium is down one row, so it's going to be a little bigger, but when we're thinking about size, it maybe does not seem that significant to talk about the size.
它们唯一的不同点,就在于其中一个在周期表的下面,钾在下一行,因此它要稍微大一些,但是当我们考虑尺寸的时候,似乎讨论尺寸的意义不大。
Also, you'll notice that the size of the body part represented in the brain does not correspond to the size of the body part in the real world.

OK, that's not so bad. Moving a stack of size 2 if I want to go there, I need to put this one temporarily over here so I can move the bottom one before I move it over.
好,并不那么难,移动上面两个圆盘的话2,我需要把最小的盘子,临时先放到多余的柱子上来,这样才能在把它移过来之前,把最底下的盘子放到目标柱子上。
And small is not derogatory here, by the way, it just says the size of things you're going to be able to do.

We don't seem to be doing that just yet, certainly not as badly, alright, so at this point in the story I have a sorted list of size 4.
当然现在我们不需要那样做,此时此刻,我已对整个问题中大小为4的列表排好序了。
Typical characterization, not all the time, but typical characterization, is an algorithm that reduces the size of a problem by one, or by some constant amount each time, is typically an example of a linear algorithm.
我们学习过了线性算法,它的典型特征,不是通用的,但是比较典型的特征是,它是逐一减小问题的大小的,或者说是每次减小常数的大小。
And when we talk about size, I'm again just going to say the stipulation we're not talking about an absolute classical concept here, but in general we're going to picture it being much further away from the nucleus as we move up in terms of n.
当我们说到尺寸时,我们只是说――,经典的绝对的概念,而是它大约,离原子核有多远。
It says while the index is smaller than the size - of the list, I'm not at the end of the list and I don't have an answer yet, check.
当然是如果我还没检索到目标数的话,因此我会去看看是不是,这里真的看不情。
And by that, I mean, not how much memory do I need to store the size of the input, it's really how much internal memory do I use up as I go through the computation?
需要占用多少内存,我意思并不是,存储输入需要多少内存,而是当我完成这个?
They are always say 32 bits or always 64 bits they do not vary in size based on what they're pointing at.
它们总是32位或者总是64位,它们的大小不会因它们所指的,内容不同而不同。
That this recursive call had two sub-problems of a smaller size, not one.
而不是一个,这会有很大的不同。
They're named after rivers and they don't all-- they're not all the same size.

Now if you lived in a culture where the only meat that got served was the size of a deck of cards, and the only pasta that got served was the size of a tennis ball, there wouldn't be such problems, but that's not the case.
如果我们生活在一个,肉类每日摄入量是一副牌大小,或者意大利面只有网球大小的环境中,问题就不会存在,可惜这不是现实
So the DNA is going to get spread out on this gel according to size, with the small ones going farther and the large ones not going as far.
因此DNA会根据大小,在凝胶上分散开,小的片段会快一些,大的片段不那么快
