The Bizarre Behavior of Rotating Bodies
推荐理由
Derek Muller on the youtube channel Veritasium has a good video on this
强烈推荐BubbleRings · 原文
说明
这是2019年由Veritasium发布的一部讲解,主题归在Fundamental physics。它讲的是rotational dynamics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:Veritasium explains the Dzhanibekov effect, also called the tennis racket theorem, where a spinning object flips unexpectedly about its intermediate axis. The video gives an intuitive account of the underlying rotational dynamics, drawing on Terry Tao's explanation and the original papers.这些读者给出的理由,核心是:HN people cite it as the clearest layperson-friendly explanation of rotational instability whenever spinning bodies, tumbling objects or axis shifts come up.讲法不绑某一条新闻,过几年仍然可以当材料看。从2020年到2025年,有1位不同的读者在1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rotational dynamics变成能跟着复述的例子。
