# What is the link to question intuitive understanding of $\sum \frac{1}{k2^k}=\ln 2$?

What is the link to question intuitive understanding of $\sum \frac{1}{k2^k}=\ln 2$ ? I tried google and various ways, including walking the list questions in the chronological order as far I thought it might be relevant to no avail.

It's post 55505, with URL https://math.stackexchange.com/questions/55505. Those who have under 10000 points and are not moderators will not be able to view it at that link, because it was deleted by the owner about 18 minutes after it was posted.
