PickVidsThe Geometry of Causality
推荐理由
here are some good ones around humans and the universe.
说明
这是2017年由PBS Space Time发布的一部讲解，主题归在Fundamental physics。它讲的是relativity and causality这一支里的具体问题，而不是把整个领域扫一遍。适合第一次接触、还没有先修课的人。内容上可以概括成：PBS Space Time explains how spacetime geometry and light cones determine the order of events and what can cause what. It visualizes causality in special relativity.这些读者给出的理由，核心是：Used as a go-to reference for relativity arguments, such as spacetime intervals being the same for all observers, and as a suggested follow-up for physics fans.讲法不绑某一条新闻，过几年仍然可以当材料看。从2017年到2022年，有2位不同的读者在2个不同月份把它推荐出来，其中明确叫别人去看的有0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relativity and causality变成能跟着复述的例子。
