How Do You End Your Proof?

How Do You End Your Proof?

Math nerds, unite! This meme perfectly captures the evolution of mathematical sophistication. Starting with the classic "Q.E.D" (quod erat demonstrandum - "that which was to be shown"), moving to the empty box symbol, then the filled black box, and finally... "Q.E.F" (quod erat faciendum - "that which was to be done"). That last panel with the maniacal grin is every mathematician who's ever flexed by using the ultra-rare Q.E.F instead of Q.E.D to end their proof. It's basically the mathematical equivalent of dropping the mic!
