Because I could've built that in, it says if you change the value of this thing, by the way you need to change recompute those other values in order to make this hold up.

我想要大家通过定义好的方法，来改变实例的值了,因为我可以把这个功能，内置到方法里面去,它的意思就是如果,你改变一个值。

Right, so the fundamental idea then, is, I want to glue together information, I want to take pieces of data that naturally belong together, glue them together, and attach some methods to it.

放在一起的数据拿出来，把它们放到一起，然后把一些方法附加上去,这些，你知道的，是很长的一个定义，让我们来看个例子吧。

So, these are two different definitions of how to think about atomic radius, but really what you find when these are measured is they come up with almost the identical values, so there are tables, you can look up of atomic radii and see these values, and you can trust them that, they work for both this definition and for this definition here, in most cases.

这就是,关于原子半径的两种不同的定义，但实际上你会发现按照这两种方法,测量出的值是相等的，因此有很多关于原子半径的表格，你可以通过查阅它找到这些值，你可以相信这些值，它们对于这两种定义都是适用的，在大多数情况下。

When I try and evaluate that expression of greater than, is going to go into the class to say greater than is a comp method.

这个大于的操作符的时候,是到类的定义里去识别，大于是一个比较的方法,那么让我在这里说仔细一点吧。

A good, hygienic way of doing this is, not only do I not go in and change things except through a pre-defined method, I shouldn't read it other Cartesian than through a pre-defined method.

做这个的方式是，我不仅仅要通过提前定义好的方法,来改变数值,我还应该通过提前定义好的方法，来读这个值,我应该用。

It's there accessible to me.

我要通过提前定义好的方法。
