We all move at the Speed of Light
推荐理由
I know a lot of people find this video helpful in conceptualizing things.
说明
这是2018年由ScienceClic English发布的一部讲解,主题归在Fundamental physics。它讲的是special relativity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:ScienceClic explains why nothing can go faster than light by treating motion through space and time together, so everything moves at the speed of light through spacetime. It uses animated visuals to cover relativity basics in 12 minutes.这些读者给出的理由,核心是:HN commenters recommend it as a helpful way to conceptualize why light speed is a limit.讲法不绑某一条新闻,过几年仍然可以当材料看。从2020年到2024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special relativity变成能跟着复述的例子。
