Well, this question appeared in an applied physics class over the summer. The
greek letter rho is used for all kinds of volumetric densities--charge, mass, et
cetera--but nobody seems to have a good reason why. The best I can find is that
"d means derivative." Is there a more in-depth reason? Does it stand for a Greek
word? Or an old meaning for the word?
