![]() ![]() So we just tell the blind man to push the door because he will feel the word PULL backwards."Īlbert Einstein: "Indeed. Richard Feynman: "Wow, Einstein, that's brilliant. So he will actually feel the letters as L L U P, which is like saying 'push' backwards." 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. Richard Feynman: "Wait, but why push and not pull? The word on the door is PULL, not PUSH."Īlbert Einstein: "Ah, but you see, the word is in mirror writing. The man just needs to tell the blind man to push the door instead of pull." So the blind man can't read the word PULL but he needs to know what to do to open the door."Īlbert Einstein: "Yes, I understand the situation. 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. I think we've reached a clear and logical conclusion for this problem. The reason is that the door is designed to be pulled open on the blind man's side, as indicated by the mirror writing on the glass door.ĪE: Well said, Richard. RF: So, our final answer to the question is: The man should tell the blind man to pull the door towards himself. This way, the blind man can open the door with ease, and there is no need to confuse him with unnecessary information. The best course of action would be for the man to simply instruct the blind man to pull the door towards himself, without mentioning the mirror writing. He might get confused if the man explains the situation in detail.ĪE: I agree. But we should also consider that the blind man might not be familiar with the concept of mirror writing. So, the man should tell the blind man to pull the door. The man seeing the reversed word implies that he is on the side where the door should be pushed. If the word says "PULL," it indicates that the door must be pulled towards oneself to open it. Now we must consider the mechanics of the door. Since the blind man is on the other side of the door, and the man sees the word reversed, that means the blind man is on the side where the writing appears correctly, which is "PULL."ĪE: That's correct. Since the man sees "PULL" written in mirror writing, that means the word is reversed, like "LLUP." Now, we must determine which side of the door the blind man is on, and how the door operates. What should he tell the blind man to open the door and why?Īlbert Einstein (AE): Ah, Richard, this is indeed a fascinating problem. A man sees the word "PULL" written in mirror writing on a glass door, and there's a blind man on the other side. Richard Feynman (RF): Hello Albert, we have an interesting question to discuss today. What should the man tell the blind man to open the door and why? There's a blind man on the other side of the door. Q:Richard Feynman and Albert Einstein collaborate to solve the following question, write out their discussion and final answer:Ī man sees PULL written in mirror writing on a glass door. ![]() If you let gpt-4 think a bit more step by step it changes the answer. ![]()
