Query: Redefines 'reading between the lines'

This is one of the most confusing and discouraging physics textbooks I've ever read. Faber has an annoying habit of using symbols without properly defining what they are, or only defining them much later in the text, which leads to extreme confusion and frustration. Furthermore, he covers the topics in a wierd order, making it extremely hard to compartmentalise information, especially if you're a first-time reader (to fluid dynamics). What exasperated me most was the fact that Faber simply dumped equations on me without properly deriving them. Faber set out to write a comprehensive book on fluid dynamics for physicists, but in my opinion has come out short. Way short.
