An easier and less mathematical riddle this week for the benefit of @aliholli and @nixenpixen:
Suppose you’re in an empty room with no method of escape. The only object in the room is a transparent glass of water. The glass is a perfect cylinder which looks half full, though you can’t be sure exactly. You are only allowed to leave the room if you can accurately determine whether the glass is half full, more than half full, or less than half full. How would you do so?
