3Blue1Brown 从收敛级数一路推演至发散级数，带观众领略 2-adic 度规的几何直觉，深入探讨数学究竟是被发现还是被发明的哲学命题。
为什么 HN 推它
Grant Sanderson 最受喜爱的代表作之一，用绝美可视化将 p-adic 数与 1+2+4+... 级数讲得清清楚楚。
「极具启发性的绝佳入门。」HN 网友原话：Great intro
英文原摘要（HackerTube / Claude 整理）
3Blue1Brown explores infinite sums from convergent to divergent, with an introduction to the 2-adic metric, themed on the cycle between discovering and inventing mathematics.
Recommended as a favorite Grant Sanderson video and a visual introduction to p-adic numbers and sums like 1+2+4+...

I loved this video
Here are my favorite videos by Grant
3lue1brown has a great visualization of constructing p-adic numbers and calculating their metric through the lens of 2-adic numbers
Great intro
for those who want to have a taste of p-adic numbers, see 3b1b's video
