Question 623355: I was given the impression that this is more of a physics "problem" written in algebraic form. But since I am an undereducated 64 y/o, over drugged, bedridden invalid and saw this tattoo on the shoulder of my son's latest love interest (physics major), I am a bit concerned. It goes:
C = 1 OVER THE SQUARE ROOT OF "ME". Is this a statement that she is wholly into "me" or does this imply something I might want to be concerned about. I know this is thoroughly out of the ordinary. I do appreciate anything you can tell me. Thanks. Linda Joiner (MIDASMUM@MAIL.COM)
