That's an excellent example.  It reflects library practice of
subdividing collections based on the number of shelf-feet of books.
(The terms 'broader' and 'narrower' are literal, not metaphorical.)    (02)

Every subject has such weird nooks and crannies, and anybody who thinks
that subject X is more precise is guaranteed not to be an expert in X.    (04)

People often use physics as an example of a very precise science.
It's true that some things are precise, but there's a continuum.    (05)

To paraphrase Bismark's principle of laws and sausages, "People
will sleep sounder if they don't see how physicists derive their
theories or engineers apply them."    (06)
