What Everyone Gets Wrong About Gravity
推荐理由
his videos on special [1] and general relativity [2] were real eye-openers for me
强烈推荐fsh · 原文
说明
这是2020年由Veritasium发布的一部讲解,主题归在Fundamental physics。它讲的是general relativity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, with expert input, that in general relativity gravity is not a force and objects follow straight paths through curved spacetime, including why standing on the ground means you are accelerating.这些读者给出的理由,核心是:HN links it as a go-to intuitive explanation whenever gravity as spacetime curvature or free fall comes 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7位不同的读者在5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general relativity变成能跟着复述的例子。
