PickVidsWhat If Alien Life Were Silicon-Based?
推荐理由
PBS Space Time has a very good & informative episode covering this.
说明
这是2023年由PBS Space Time发布的一部讲解，主题归在Chemistry。它讲的是alien biochemistry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：PBS Space Time considers whether life could be based on silicon instead of carbon, comparing the two elements' chemistry and why silicon is the most plausible alternative.这些读者给出的理由，核心是：Recommended as a solid, informative treatment of silicon-based life and the chemical limits on alien biochemistry.讲法不绑某一条新闻，过几年仍然可以当材料看。从2023年到2025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alien biochemistry变成能跟着复述的例子。
