The 5 Most Dangerous Chemicals on Earth
推荐理由
This is a fun video to watch
说明
这是2014年由SciShow发布的一部讲解,主题归在Chemistry。它讲的是dangerous chemicals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 SciShow episode in which Hank Green introduces five of the most dangerous chemicals, from lethal toxins to substances that explode on contact. It is an entertaining overview of extreme chemical hazards.这些读者给出的理由,核心是:Recommended as a fun companion to threads about hazardous chemistry, such as hydrofluoric acid and reactive substances.讲法不绑某一条新闻,过几年仍然可以当材料看。从2015年到2020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dangerous chemicals变成能跟着复述的例子。
