推荐理由
thought wow this is good. Much better than the physics lectures I had at Cambridge Uni.

说明
这是2025年由Veritasium发布的一部讲解,主题归在Fundamental physics。它讲的是noether's theorem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 explores why energy is not conserved in general relativity, using Emmy Noether's theorem linking symmetries to conservation laws. Physicists interviewed explain energy loss in an expanding universe.这些读者给出的理由,核心是:Recommended as high-quality physics communication and as an introduction to Noether and energy non-conservation in cosmology.讲法不绑某一条新闻,过几年仍然可以当材料看。从2025年到2025年,有3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noether's theorem变成能跟着复述的例子。
