I bought 1000 meters of wire to settle a physics debate
推荐理由
Yeah I really liked the AlphaPheonix video[0] where he actually built the thing in a field and explained the entire effect properly.

说明
这是2021年由AlphaPhoenix发布的一部演示,主题归在Electronics & circuit design。它讲的是electricity propagation这一支里的具体问题,而不是把整个领域扫一遍。适合已经能看懂基本术语、想继续往下走的人。内容上可以概括成:AlphaPhoenix builds a scaled-down version of the Veritasium electricity thought experiment using about a kilometer of wire and an oscilloscope. He measures how the signal actually propagates and explains the result.这些读者给出的理由,核心是:HN considers it the best experimental rebuttal and clarification of the Veritasium wire debate, with real measurements.讲法不绑某一条新闻,过几年仍然可以当材料看。从2021年到2026年,有8位不同的读者在8个不同月份把它推荐出来,其中明确叫别人去看的有3次。适合先看结果再决定要不要深挖的人。先看它做成了什么。如果已经会了基本定义,就把注意力放在它怎么把electricity propagation变成能跟着复述的例子。
