The internet sure does this often enough, but the final straw came from, of all things, Analog Science Fiction & Fact Magazine! If I can’t expect them to keep mathematical terms separate from non-mathematical terms, who can I trust?

You see, discrete means separate, distinct, noncontinuous. Discreet means prudent, modest, cautiously silent. When someone says a person is ‘discrete’, I have a vision of that person scattered across a Cartesian plane in pieces. Please, save me from gory geometrical visions! Use these words correctly!
