What we're saying is, in order to do computation, we want to describe recipes, we want to describe this sequence of steps built on some primitives, and we want to describe the flow of control that goes through those sequence of steps as we carry on So the last thing we need before we can start talking about real programming is, we need to describe those recipes.

我们在说，为了做计算，我们想描述一个方法，想描述建立在,相同基本类型上的步骤序列，而且我们想描述经过我们设计的,步骤的序列的，控制流程,因此我们开始谈论真正的编程之前,的最后一件事是，我们需要描述一下那些方法。

They take those descriptions and the scientist that is known and they try to design new things, and so if you look at a dictionary it has words like this, that you're designing things or another way to say that is that you're trying to apply science, you're looking at applications.

他们利用已知的,科学原理和描述,来设计新东西,因此,如果你查字典时看到这样的词条,设计产品或者换句话说,试图应用科学原理,那么你看的这个词就是应用
