How are holograms possible?
推荐理由
this might be one of my most favorite videos ever single-handedly changing my understanding of holograms
强烈推荐omneity · 原文
说明
这是2024年由3Blue1Brown发布的一部讲解,主题归在Fundamental physics。它讲的是holography这一支里的具体问题,而不是把整个领域扫一遍。适合按兴趣直接看、不打算先补课的人。内容上可以概括成:3Blue1Brown explains how holograms record a 3D scene on 2D film, using wave diffraction and phase. The video includes demonstrations of several real holograms.这些读者给出的理由,核心是:HN commenters call it the best explanation of how holograms work, and one says it transformed their understanding.讲法不绑某一条新闻,过几年仍然可以当材料看。从2024年到2025年,有3位不同的读者在3个不同月份把它推荐出来,其中明确叫别人去看的有1次。适合用一集把一个概念补上的人。抓住它用的那个图像或类比,比背公式重要。如果已经会了基本定义,就把注意力放在它怎么把holography变成能跟着复述的例子。
