well the abbreviated names include the letters, you can get in trouble when questions tend to have many symbols appended together.

I should clarify, though, that I was thinking of college physics classes, which are definitely more mature, both about exploring new knowledge instead of memorizing facts, and about learning to actually speak in the experts' language.

Using symbols for common concepts without defining them is, however, absurd. (Not counting a few -- c, e, hbar, m, maybe q?)
