All right, so that notion of abstraction and we're going to come back to multiple times -- during the term-- and it's not just abstraction, -- it's the idea of a specification.

现在就试试,这就是抽象的概念,我回过来说，我们将要多次提到这个术语。

This is just a little inelegant and so one of the things we'll introduce early on is this idea of abstraction or design whereby if you wanna represent the ideas of 0 and 1, true or false, well, let's give them a synonym like true or false.

这么说有点粗野,我要接着讲的是这种抽象的思想,或者用这个来描绘设计出,真和假的思想，我们可以给真假各指定一个同义词。

What we're really getting at is the idea of saying I want to have a way of grouping together information into units that make sense. So I can go back to one of those topics we had at the beginning, which is the idea of abstraction, that I can create one of those units as a simple entity, bury away the details and write really modular code.
