We'll do a little catalog of them: "Of Man's First Disobedience and the Fruit" - that was line one, of course.
我们来数一下:,“关于人类最初违反天神命令偷尝禁树的果子“,-这是第一句,当然。
So check that I counted right, 1, 2, 3, 4, 5, 6, 7, 8 and 1, 2, 3, 4, 5, 6, 7.
查一下我数的对吗,12345678,和1234567
The reason I want to point this out to you is, if we go back up to the kinds of data objects we started with, floats, ints, strings, they actually behave the same way.
我要为大家指出这一点的原因是,如果我们想一下以前讲过的,数据类型的种类,浮点数,整数,字符串,它们实际上有相同的行为方式。
Would one of the TAs count, because I don't want to. Just hold your hands up.

Most censuses were taken, by the way, as a way of counting heads, the number of people who had to be fed at the time of a siege.
顺便提一下,大多数人口普查,都采用数人头的方法,即在围城期间统计需要给养多少人口
And then we'll go ahead and count some measures.
然后我们再开始数一下小节
These were very young scientists, of course, so what you would expect that they would do, which makes sense, is go to someone more established in their field, because they have the completely radical revolutionary idea, let's just run it by someone before we go ahead and publish this paper that makes this huge statement about this fourth quantum number.
他们是非常年轻的科学家,所以你们可以想象他们会怎么做,很自然的,他们去请教他们领域里更权威的人,因为他们的概念是彻底的革命性的,让我们在发表这个关于,第四个量子数的巨大的发现之前,先和别人讨论一下。
It turns out that if you look at the 2.5--sorry, the quarter million people on the movie database and compute their Bacon number, 2.8 the average Bacon number is 2.8.
结果发现,这2。5…对不起,如果你算一下电影数据库里这25万人,他们的平均Bacon数为。
This is our row and at the count of three we're going to see who's going to run.
我们用这排,数到三的时候,我们来看一下谁会参选
So it looks like a lot of - well we're going to find out, we're going to count--but a lot more Alpha's than Beta's.
我们来数一下,确认一下,选α的人要远远多于选β
All right. I tried it on 2, I surely didn't expect a precise and exact answer to that but I got something, and if you square this, you'll find the answer kept pretty darn close to 2.
好,我试试求2的平方根,我当然不希望得到一个完全准确的答案了,但是我得到了一个近似值,试试将这个数平方一下,你会发现结果和2相当接近。
And also I wanted to mention in terms of checking your Lewis structures, regardless of what they are, you should always go back and I had 10, and then count 2, 4, 6, 8, 10, because you always need to make sure you have the same number of valence electrons that you calculated in your actual structure.
我还想提一点关于检查,你的路易斯结构的建议,不管它们是什么,你总是应该回去检查一下,我有十个,然后数一数,二,四,六,八,十个,因为你总是需要确保实际价电子的数量,与你在结构中算出的数量相等。
And, I mean literally, mass, not mole number.
我想罗嗦一下,质量,而不是摩尔数。
So what we want to do now is to begin to think about counting measures, and we're going to do this by staying with this piece of Louis Armstrong here, and we need to be able to count measures so that we can figure out the syntax of music.
现在我们想做的,是大家开始想一下怎么数小节,我们通过,路易斯·阿姆斯特朗的这段乐曲,来做这个活动,我们需要能够数好小节才能弄清楚,音乐的句法
And that's just to take 1 the principle quantum number l and subtract it by 1, and then also subtract from that your l quantum number.
主量子数,减去,再减去,量子数,你们可以对1s轨道来验证一下。
Let's count. 1, 2, 3, 4, 5, 6, 7, 8, 9 he's going to get 10 votes, including himself there are 10 votes here.
我们数一下1233456789,他将获得10票,包括他自己的票数在内有10票
