I retired in 2006 and bought Mathematica and a stack of math books with the goal to teach myself to become a worldclass mathematician. I am on pace to achieve that goal sometime shortly after the next Ice Age.
I consider myself a Mathematical Mutt (no papers) who occasionally ventures off the back porch to play in the yard with the big dogs.
I donate regularly to the The OEIS Foundation.
When I look at the patterns, I can hear the wheels turning. When I look at the math, I find out the hamsters have died.

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 $a_k=\dfrac{3^{2^{k1}}+1}{2}$?

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 boardfeet of a log. The volume of this kerf is the sawdust.

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.

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 nonspecialty duties. Therefore, less time for creativity and thus fewer papers.

$\zeta(0)$ and the cotangent function
From Edwards, p 12, (1): for $n=0$,$$\zeta (2 n)=\frac{(1)^{n+1} 2^{2 n1} \pi ^{2 n} B_{2 n}}{(2 n)!}=\frac{(1)^{n+1} 2^{2 n1} \pi ^{2 n}}{(2 n)!}=\frac{1}{2},$$ with and without the Bernoulli number.
