comment Where can square roots come from when they are not distances?
That is not correct. $3 * 7 = 21$ and $7>21^{\frac{1}{2}}$

@DelioMugnolo, additional observation---D-WAVE's quantum computer is analog.

comment Deep Learning / Deep neural nets for mathematician
@DelioMugnolo, When I experimented with neural nets (as a hobby), I saw the analogy to bridge networks---plug in an unknown resistor (say) and read its value on a meter. The pieces of the bridge would be somewhat like the nodes of a neural net. It is only my take on the process.

comment Proposals for polymath projects
One possible finite set to evaluate: Each prime in the product is found in half of the square-free divisors of the product: Table[GCD[Divisors[2*3*5*7], n], {n, {2, 3, 5, 7}}] // MatrixForm $\left( \begin{array}{cccccccccccccccc} 1 & 2 & 1 & 1 & 2 & 1 & 2 & 2 & 1 & 1 & 2 & 1 & 2 & 2 & 1 & 2 \\ 1 & 1 & 3 & 1 & 3 & 1 & 1 & 1 & 3 & 3 & 3 & 1 & 3 & 1 & 3 & 3 \\ 1 & 1 & 1 & 5 & 1 & 1 & 5 & 1 & 5 & 1 & 5 & 5 & 1 & 5 & 5 & 5 \\ 1 & 1 & 1 & 1 & 1 & 7 & 1 & 7 & 1 & 7 & 1 & 7 & 7 & 7 & 7 & 7 \\ \end{array} \right)$

comment For $k>3$ does there exist an odd prime $q_k$ such that $p_k=2^kq_k+1$ is prime and $p_k$ divides $a_k=\dfrac{3^{2^{k-1}}+1}{2}$?

comment Uninteresting questions with interesting answers
@bubba, Carpenters call it kerf and they must account for it to build things. Sawmills do the same to determine board-feet of a log. The volume of this kerf is the sawdust.

comment Primes and Parity
1) Assuming Oppermann's conjecture, if you set $k=N+1$, you have primes in every interval. Don't know about the parity, though.

comment Are there any serious investigations of whether “mathematicians do their best work when they're young”?
I think that as an individual becomes more accomplished in her specialty, her employer rewards her with promotions. Each step up that ladder requires more time for non-specialty duties. Therefore, less time for creativity and thus fewer papers.
