@StevenTaschuk more dangerously, proof of CLT is usually built on estimates of binomial coefficients

comment Prove that the diagonal $∆$ in $S^2×S^2$ is not globally definable by $2$ independent function.
what does globally definable mean?

It's no coincidence I pick Freeman Dyson and Ramanujan since they occasionally worked on the same subject. In addition to QED, Dyson also worked in number theory en.wikipedia.org/wiki/Ramanujan%27s_congruences

I was hoping we can use Descartes Circle Theorem. We can identify 4 circles: * the circle $O_A$ with center at $A$ * circle with diameter $\overline{AP}$ * circle with diameter $\overline{PB}$ * unknown circle Unfortunately, these 4 circles are not mutually tangent since the circle with diameter $\overline{AP}$ is not tangent to the circle $O_A$ with center at $A$.
