Soviet-era math meme goes viral: continuous functions and absolutely convergent series nostalgia

teortaxesTex · x · 2026-10-15

A beloved Russian math meme parodying nostalgia for the Stalin era: back then all functions were continuous (people would rush to fix any discontinuity and apologize to the argument), the whole country—even infinite-dimensional space—was compact, and every series converged absolutely. Legend has it rearranging two terms of the harmonic series once earned you 300 rubles. Fail to prove a theorem on an exam? The professor would hug you, declare it obvious, give you a 5, and offer a joint publication.
