Quod Erat Demonstrandum - That which was to be demonstrated. Quod Est Demonstrandum - This is the demonstration? vis: "Cas. 1. Rectangulum quodvis motu perpetuo auctum AB ubi de lateribus A & B deerant momentorum dimidia a & b, fuit A - a in B - b, seu AB - aB - Ba + ab; & quam primum latera A & B alteris momentorum dimidiis aucta sunt, evadit A + a in B + b, seu AB + aB + Ba + ab. De hoc rectangulo subducator rectangulum prius, & manebit excessus aB + bA. Igitur laterum incrementis totis a & b generatur rectanguli incrementum aB + bA. Q.E.D." There are two QED's, I think. Usually when people use the QED initials, it is to say they have demonstrated something, not that something might be demonstrated in the abstract, let alone in the past tense. Now I don't have my high school Latin book with me, and I was no Latin scholar anyway, so you could be right. However, Latin was a living language for 1500 years, with a great variety of forms, and so, quotations. As many as English, perhaps. When you say wrong, you have to say when. I think I would have it right in Attic Latin, at least. After all, this is a quotation, or at least an idiom. Prove that they never said it that way, why don't you :-) Of course, if I have stumbled onto the SI equivalent of William Safire, I won't win this one, so I yield in advance. If, on the other hand, you picked up your dictionary and chose definition one, then serve again and I'll try to return. Cheers, Chaz
