===================================
the math book uses weight and mass nearly interchangeably.
For a math book, that's not the least bit unusual.
There are lots of real-world situations where, depending on
context, it may or may not be appropriate to
-- distinguish between cows and steers
-- distinguish between blue and cyan
-- distinguish between lawyer and attorney
-- distinguish between weight and mass
-- et cetera.
Sometimes it matters, sometimes it doesn't. Even if _you_
are super-precise all the time, you can't expect everybody
else to make the distinctions when they don't matter. But
you _can_ insist that people in your class learn to recognize
when it does matter, and to do it right when it does matter.
