If I want to express a weird feeling as to the strange atmosphere
in a classroom, I don't have to say, "YOU ASSHOLES ARE REALLY SO....
ASSHOLE-LIKE!"
Instead, I just have to write down an equation on the blackboard as
follows:
ψ(A,B,C,D) = k [I]^a [ρ]^b [T]^c [D]^d
ψ: My positive feeling
k: constant
I: Illumination in that room (Suppose in certain domain the amount of
light in proportion to the function value)
ρ: oxygen density (More oxygen to breathe is better)
T: a functional related to temperature
D: another functional related to population density in the classroom (more
people, more bad feeling)

Don't ask me how I know this equation is correct. I don't care. It's just
a language. As long as some one can understand, just as you don't question
why the alphabet has to look that way.
