@MarcvanLeeuwen Yes, I put that there to avoid consideration of the trivial case.

@KonstantinosGaitanas Yes, you may move coins from any pile $x$ to any other pile $y$, but only such that the number of coins in $y$ is doubled.

This is a great answer! Quite $(\heartsuit)$ly.

comment Can the Basel problem be solved by Leibniz today?
Thanks, I am aware of the above relations. I found a reference that establishes that given one more ingredient, (1) is sufficient to infer (2) - as far as heuristic arguments go (see here). Also, this talk seems to indicate that Newton's theorem (which must have existed pre-Leibniz?) is sufficient to infer (2), again the rigor is forsaken.

comment Probability that n points on a circle are in one semicircle
Why is $ \lim_{k\to\infty}k2^{-n}\left(1-\left(1-\frac2k\right)^n\right)=\lim_{k\to\infty‌​}k2^{-n}\left(\frac{2n}k\right)$ true?
