物理泰斗 Richard Feynman 被记者问及“磁铁为何相斥”时的传奇短片。他没有直接背公式，而是敏锐地解构了“为什么”这个提问本身——阐释任何现象都依赖彼此共识的认知框架，生动诠释了向大众解释物理底层的艰难。
为什么 HN 推它
HN 讨论科学解释、认知参照系与沟通界限时必引用的传世金句视频，被誉为应对所有“为什么”质问的最高水准回答。
「我很喜欢拿费曼回答“磁铁为什么会相互排斥”的那个视频去启发别人。」HN 网友原话：I like to refer people to Feynman's answer to a question about why magnets repel each other[0].
英文原摘要（HackerTube / Claude 整理）
A short clip of Richard Feynman answering an interviewer's question about why magnets repel, explaining that a 'why' question depends on a shared framework of understanding. It illustrates how hard it is to explain fundamentals to a layperson.
Cited constantly as the classic answer to 'why' questions, on explanation, frames of reference and the limits of physics.
HN 上的提及
we can actually listen here Feynman's answer to " what is the meaning of... " and " why " questions

I think this video is a very good illustration of this fact
The take away is to answer a why question you need a framework to provide an acceptable answer.
Indeed, questions of why are often metaphysical and can't truly be answered within the framework of physics.
