OK, in a few minutes we're going to start talking then about what is computation, how are we going to start building those tools, but that's what you should take away, that's what you're going to gain out of this course by the time you're done.
好啦，我们会花一点儿时间,谈谈什么是计算，我们如何去建造这些工具，但是这些是你应该，在离开这个课堂时,应该学会的事儿。

Now this is mostly irrelevant to what we're talking about except for the fact that there are magnetic particles involved and they're really small because it turns out what's inside most of your laptops and desktop computers are these things called hard drives.
其实这与我们现在谈论的话题没什么关系,除了这里的磁性粒子有关系外,它们是很小的因为它们要放在,你的笔记本电脑或者,台式机中被称为硬盘的里面。

What we're going to talk about next time, and I encourage to read ahead because you'll see that there's a lot more detail in Chapter 6 than what we're talking about here, I've emphasized the main points, the ones that I think are important, that are clearly important for your understanding.

And there's a lot we can explain by talking about what we see in the periodic table in terms of what different trends are in grouping different elements in different spots within the periodic table.

And what we've been talking about with all of these properties are, of course, how can we figure out what that is for a certain atom by looking at the periodic table, so we want to think about the periodic trend for atomic radius.

So, operands. Let us take expressions, get values out, we can store them away in places, but ultimately we want to do something with them, so we need to now start talking about what are the things we can do inside of Python, or any programming language, to manipulate them.
也就是运算对象，让我们看看这些表达式，然后看看里面的这些值，我们可以把他们存在计算机的任何位置中，最终目的还是要对这些值做一些操作，因此我们现在需要开始讨论,在Python里面可以做什么，来操作它们了，或者在任何编程语言里。
