I mean, if the energy is lower to occupy a smaller volume, then if I have this room and a bunch of molecules of oxygen, and nitrogen and what have you in the air, and there are weak attractions between them, why don't they all just sort of glum together and find whatever volume they like.
我的意思是，如果占据小的体积会使能量降低，如果我有这样一个空间,和一些氧气，氮气和其他空气中有的气体，并且分子之间还有微弱的相互作用，为什么他们不黏在一起,然后占据他们所想要占据的体积。

You remember in the first lecture I said there's a difference between the history of criticism and theory of literature, one difference being that the history of criticism has a great deal to do with literary evaluation: that is to say, why do we care about literature and how can we find means of saying that it's good or not good?

And just to look ahead a little bit, you could easily imagine that I might want to not just put a statement in there, what the specs are, I might want to put some constraints. Some specific things to check for, to make sure that you're calling the code right.
这不仅是抽象的概念还有规范的概念，我们再往前看看,你可以简单的想象得到，我不仅仅是想在这里加一个声明,这些规范说明中我还想加一些约束，我们要注意一些特殊的事情。

And often, if you want to make a lot of it, you have to think about the thermodynamics of the system, how fast the reactions will go and kinetics, and then whether they'll go, the thermodynamics, and sometimes then you need to adjust the reactions, maybe use a transition metal to make it go better.

Now, a foreword is of course supposed to suggest how you should read the text that's coming. And so, if we take it on in that role, let's see what we see.

that's one way to think about it, and there's also another way, and this is the way that your book presents it. If you, in fact, have two of the same atom right next to each other, let's say you have a crystal, or let's say you're talking about a metal, what you can do is just look at the distance between the two nuclei, and split that in 1/2, and take the atomic radius that way.
这只是一种定义的思路，另外还有其它方法，也就是你们课本上的方法，如果你，事实上，有两个相同的原子彼此靠在一起，比如说你有一个晶体，或者说你讨论的是一个金属，你所要做的就是,看看这两个原子核之间的距离，然后将距离除以二，就得到了这个原子的半径。

But at the end of the day, the point of the slides is not to expect you to now go write programs in C but really to just remind you that, hey, if you ever get distracted from some of the minutia that is the semicolons, parentheses, and what is very new to many of you, it's really no different than the fun and games we implemented with Scratch last week.
但是最终，我们课件上讨论的主题,并不是让你现在就写一个C语言的程序,而是要告诉大家不要你被那些分号括号,还有一些从未见过的符号等一些细节搅得心烦意乱，因为它们本质上,和我们上周用Scratch做出来的游戏,并无区别。

But just go to cs50.net, click office hours and you'll see the Google Calendar with all of the office hours that are still happening tonight, as well as tomorrow and these are just an opportunity to chat, to ask questions one on one with the teaching fellows or course assistants or frankly just a way to hang out during brain break and work on projects and then see what some of your friends might be tackling themselves.
但是我要提醒大家去cs50，net网站看看,这里清清楚楚告诉你,什么时候该学习工作，当然也包括今晚的明天的，我们还有一个机会供，一个与研究生助教或课程辅导员交流的机会,更直白来说,是提供你们开小差的机会,看看你们周围哪些人,在开小差呢。
