"We're discussing Re-imagine! at a meeting and we don't know what Q.E.D. means," J.B. Blosser Bittner, chief of the Oklahoma News Bureau, asked us in an email. Good question. Mathematicians and philosophers of yore wrote Q.E.D. (short for quod erat demonstrandum, what was to be proven) at the end of their work to indicate they had proven their point. You don't get smarter by pretending to know more than you do, so asking questions is good.
