For 1d mean estimation when all we know is that variance is finite, does the median of means algorithm need to know an upper bound on the variance to get its guarantees? If yes, is there an algorithm that doesn't need to know this?

Interesting. I thought people had completely moved to ChatGPT/claude for this sort of stuff

I was surprised to see that 4th floor math/physics section has some very good textbooks!
