So we left off last time with looking at a bit of coding and teasing you with the upcoming problem set.
我们上次讲到了查看一些代码,并且给你们带来这下面的习题。
As they learned, they wrote a little bit about what their impressions were at the time.
根据所学,他们更详细地记录下,对那天的印象与感受。
Dictionaries are implemented using a magic technique called hashing, which we'll look at a little bit later in the term, which allows us to retrieve keys in constant time.
散列法的内容,此方法可以让我们在线性,时间内检索到键,因此字典的大小并不重要了。
So before we leave coordination games, I want to look at another one, a little bit more complicated one perhaps, that we mentioned briefly last time.
在我们结束讲解协调博弈前,我们再来看一个,稍微复杂点的问题,上一讲我简单提到过的
and I'm going to move a little bit quickly through all this because I want to leave time for a few questions at the end of the lecture.
我要加快进度,因为我想留点时间,最后回答你们的问题。
We'll be talking about the Phaedo starting some time next week and we'll continue the discussion of the Phaedo for at least a bit of, maybe all of, the week after that.

Okay, now let's paralleling what you've been reading let's look a little bit at the Dutch Republic at the Dutch Republic England and Britain all the time, because people talk about so let me talk about the Dutch Republic.

And the nucleus name was used as an analogy to the nucleus of a cell so in some ways that makes it easier to see the connection but I think it can also be a little bit confusing for maybe 7th graders that are learning both at the same time, that this nucleus acts very different from a nucleus in a cell, although, of course, there many of them in the nucleus of a cell.
原子核这个名字的命名,是类似于细胞核,这样会让人们更容易看到两者之间的联系,但我觉得这样可能,会给正在学这两个课程的,7年级学生带来困惑,原子核的行为,和细胞核完全不同,虽然在细胞核。
People can get hung up on sort of hunting these things down, and stamping them out, one at a time. And it's a little bit like playing Whack-a-Mole. Right?
我们可能会一次一个的去发现,这个bug并且消灭它,这有点像打鼹鼠对不对?,不停的有鼹鼠跳起来?
to the n, every value in the 1 bit vector we looked at last time is either 0 or 1. So it's a binary n number of n bits, 2 to the n.
从2到n,我们上次看到的,位向量的每个值不是0就是,所以它是n,比特的二进制数,从2到。
