This is ridiculous. Why doesn't he just say one thing at a time?"
这太荒谬了,他为什么不一次只说一件事情?“
D-A-V-I-D Well, if I've got a five-letter word like D-A-V-I-D, well, that's like five bytes and yet we only have the ability thus far in this class to return one thing at a time I can't return five bytes to you, but wait a minute, those bytes by nature of a computer are just stored in RAM.
好的,如果有5个字母的单词,如,那是5个字节,我们只能返回一个东西,而不能返回5个字节,等一下,这些字节被计算机本能地,存储在内存中。
How do you deal with that trade-off where you absolutely need an ad sales force but at the same time, if one person at a time, you just can't say let's go out and hire five good engineers or five good ad sales people and not have them be great?
如何做出选择,如何取舍,当你急需一批销售人员,但如果只碰见一个合适的人选,你不只能因此去找,5个差不多的工程师,或者5个差不多的广告销售?
Just to see that in a very simple example, again, we don't use such a complicated example as the one we looked at last time, you could imagine a game, a really trivial coordination game, which looked like this .
不妨再举一个例子,我们就不找上一讲那么复杂的案例了,看一下这个简单的协调博弈,如
I think you can tell by analogy with what I did in one dimension that the position of that object at any time t is going to be the initial position plus velocity times t plus one half a t square.
你们可以类比一下我在一维情况下的结论,这个物体在任意时刻 t 的位移,等于初始位移,加上 v ? t + 1/2 ? a ? t^2
