| GPT3's answer: Richard Feynman: "Okay, so the man sees PULL written in mirror writing on the glass door and there's a blind man on the other side of the door. So the blind man can't read the word PULL but he needs to know what to do to open the door." Albert Einstein: "Yes, I understand the situation. It's quite simple, really. The man just needs to tell the blind man to push the door instead of pull." Richard Feynman: "Wait, but why push and not pull? The word on the door is PULL, not PUSH." Albert Einstein: "Ah, but you see, the word is in mirror writing. When the blind man feels the letters with his fingers, he will feel the letters backwards, as if he is looking at them in a mirror. So he will actually feel the letters as L L U P, which is like saying 'push' backwards." Richard Feynman: "Wow, Einstein, that's brilliant. So we just tell the blind man to push the door because he will feel the word PULL backwards." Albert Einstein: "Indeed. It's a simple solution once you think about it." Final answer: The man should tell the blind man to push the door because the word PULL is written in mirror writing on the glass door, and the blind man will feel the letters backwards as L L U P, which is like saying 'push' backwards. |
