On p. 488 of Structure and Interpretation of Computer Programs (Abelson, Sussman, Sussman; 1996), the authors write
... Establishing new languages is a powerful strategy for controlling complexity in engineering design; we can often enhance our ability to deal with a complex problem by adopting a new language that enables us to describe (and hence to think about) the problem in a different way, using primitives, means of combination, and means of abstraction that are particularly well suited to the problem at hand.
Programming is endowed with a multitude of languages. There are...
And then half the page is a footnote:
- The same idea is pervasive throughout all of engineering. For example, electrical engineers use many different languages for describing circuits. Two...
I would like to quote the text, including the footnote.
How can I do so, preferrably APA-style?
(I'm not sure APA says anything about this)
