Hitting the Sun is HARD
推荐理由
as explained in the following minutephysics video (3 minutes): Hitting the Sun is HARD.
说明
这是2016年由minutephysics发布的一部讲解,主题归在Space exploration & spaceflight。它讲的是orbital mechanics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:A three-minute minutephysics video on the orbital mechanics of why crashing into the Sun takes far more energy than leaving the solar system.这些读者给出的理由,核心是:HN links it as the quick explanation of why you cannot just throw things into the Sun.讲法不绑某一条新闻,过几年仍然可以当材料看。从2019年到2023年,有1位不同的读者在1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orbital mechanics变成能跟着复述的例子。
