Here come the worms!

Dan, have you ever taken calculus? People who don't understand
graphs sink like rocks in calculus. Most publications in science
are full of graphs, and in economics and other social sciences, too.
Graphs are the lingua franca of most modern technical information,
no matter what the field.

I agree that some uses of graphing calculators
are faddish (e.g., believing that the calculator will tell you the truth
in all cases) but graphs themselves are here to stay.
