The Biggest Misconception About Electricity
推荐理由
It’s an eye opening alternative explanation
说明
这是2021年由Veritasium发布的一部讲解,主题归在Fundamental physics。它讲的是electricity and electromagnetic fields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 argues that electric energy is carried by fields around the wires rather than by electrons moving through them, using a thought experiment with a large circuit.这些读者给出的理由,核心是:Often recommended as an eye-opening field-based explanation of electricity, though it was also controversial and criticized as pedantic.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7位不同的读者在6个不同月份把它推荐出来,其中明确叫别人去看的有2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electricity and electromagnetic fields变成能跟着复述的例子。
