PickVidsOld car headlights were all the same — which was a fairly bright idea

强烈推荐jameshart · 原文
说明
这是2022年由Technology Connections发布的一部讲解，主题归在Cars, EVs & motorcycles。它讲的是automotive headlight history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：Technology Connections explains why American cars all had the same standardized sealed-beam headlights until 1957. It covers the regulations behind the design and the effect on night visibility.这些读者给出的理由，核心是：Recommended as a clear explanation of why old headlights looked as they did, and as a case study in mandating requirements versus solutions.讲法不绑某一条新闻，过几年仍然可以当材料看。从2022年到2023年，有4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automotive headlight history变成能跟着复述的例子。
