PickVidsHow Imaginary Numbers Were Invented
推荐理由
I also highly recommend Veritasium's video[1] as an excellent explainer as well, especially regarding the roots of imaginary/complex numbers in geometry.

说明
这是2021年由Veritasium发布的一部讲解，主题归在Pure mathematics。它讲的是history of imaginary numbers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：Veritasium tells the history of how imaginary numbers arose from the quest for a general solution to the cubic equation, including the duels and secrecy among Renaissance mathematicians. It argues math had to give up the requirement that it mirror reality.这些读者给出的理由，核心是：HN recommends it as a well-visualized, story-driven history of complex numbers, suitable for beginners; some quibble with its framing of algebra and geometry.讲法不绑某一条新闻，过几年仍然可以当材料看。从2021年到2023年，有7位不同的读者在4个不同月份把它推荐出来，其中明确叫别人去看的有1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history of imaginary numbers变成能跟着复述的例子。
