Experiment! How Does An Owl Fly So Silently? | Super Powered Owls | BBC
推荐理由
To really appreciate how silent Owls are as compared to other birds, see this excellent video from BBC
说明
这是2016年由BBC Earth发布的一部讲解,主题归在Animals & nature。它讲的是owl silent flight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:A BBC Earth clip from Super Powered Owls in which the team uses sensitive sound equipment to compare owl flight with other birds. It shows why owls fly almost silently.这些读者给出的理由,核心是:Linked in owl-feather and quiet-flight threads as a clear audio comparison.讲法不绑某一条新闻,过几年仍然可以当材料看。从2020年到2026年,有2位不同的读者在2个不同月份把它推荐出来,其中明确叫别人去看的有0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owl silent flight变成能跟着复述的例子。
