Mathologer：拉马努金与 1+2+3+…=-1/12 到底怎么回事

Mathologer examines how identities like 1+2+3+... = -1/12 arise in Ramanujan's work, starting from his 1913 letter to Hardy. The video explains the rules for summing infinite series and why such results are meaningful but not naive sums.

Why HN likes it: Recommended as a careful, honest treatment of the -1/12 claim, often preferred over flashier videos.
