I seem to recall being frustrated numerous times in my academic career by the preference of academia in supplying tools before supplying a reason to appreciate those tools.
For anyone who's taken calculus before taking physics, or learning imaginary numbers before taking a course in digital circuits, or learning how to work with matrices before needing to solve simultaneous sets of equations..., you know what I mean.
I'm holding out hope that this is another instance of that. We're being given tools; building understanding, before we've been shown the application.
By the end of the course, hopefully the need for what we're reading now will be crystal clear. I'm willing to wait and see.
