I retired 7 years ago and bought Mathematica and a stack of math books with the goal to teach myself to become a world-class 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 hampsters have died.

I don't think the world is ready for Fred's mathematics. – Gerry Myerson, mathoverflow.net

comment How to insert big list of Data in DB?
I don't understand the down-vote. This method is used to save and retrieve execution check-points. The data should be raw (binary) and the only reason to convert to characters is if there is a big-endian little-endian conflict when the data is used for different architects.

One other thought, is there a way to get the $10$ into the function?

Zeta[-2n] are the trivial zeros.

@MichaelE2, I did not link to this question, but here is a link to MO: mathoverflow.net/questions/130285

comment Another MoebiusMu question
@MichaelE2, In working-up the question for MO, I have realized that $\mu(\cdot)$ is not the issue. Mertens with $s=0$ is the issue. So, I might not be linking to this question anyway.

comment Another MoebiusMu question
@MichaelE2, these are the first close votes I have received on this forum. I get them regularly on math.SE and MO, usually for ill-formed questions. However, I did get a fine answer, which was my goal, so I'm fine with everything.

comment Another MoebiusMu question
+1, very nice. Since I am applying the analysis to only the $s=0$ situation, I can define MoebiusMu as I see fit (assuming I can prove it.)

comment Another MoebiusMu question
@MichaelE2, it is along that line. I am trying to use analytic continuation in the non-negative reals to define Mertens at $s=0$. Because Mathematica returns -1., I can change to a zero. But I need to know where the -1. comes from so I can explain it. I am working on a question for mathMO which I should post soon, in which I will explain my reasoning. I'll post a link here when that happens.

comment Is mathematica storing information it shouldn't store?
I have had that problem twice. The kernal stops when you run out of swap file space, so you might get it done by increasing the swap file. If this is something to be done often, you will need a better algorithm.
