中文导读
Welch Labs 虚数科普系列的开篇之作，将虚数生动地呈现为一维数轴自然延伸至二维平面的必然结果，用极高水准的视觉动画系统梳理了虚数的数学本质与发展史。
为什么 HN 推它
被 HN 网友盛赞为理解复数直觉的最佳可视化教学，对重塑数学直觉极具帮助。
「这是我在该领域见过的最震撼的音视频科普作品。」HN 网友原话：The greatest audiovisual content on the topic I have ever seen
英文原摘要（HackerTube / Claude 整理）
The first part of Welch Labs' series on imaginary numbers, presenting them as the natural extension of the number line into two dimensions. It covers the history and the math with strong visuals.
HN commenters rate the series as some of the best visual teaching on complex numbers and recommend it for building intuition.
