Dean Moore current projects

I keep busy with various projects, some tech, some non-tech. A few:

- Still do mathematics:
- Recently
digested Ian Stewart’s book on Galois
Theory, a field of which I knew little. In general, a polynomial of degree five or higher with rational coefficients cannot be “solved,” that is, its zeros cannot be expressed by extracting roots, and/or performing algebra on rational numbers. There are many examples, but the polynomial
*p*(*x*), where*p*(*x*) =*x*^{5}-*x*- 1, and the polynomial*q*(*x*) =*x*^{5}- 6*x*- 3 have no “solutions” via taking roots, performing algebra on rational numbers. Many can’t be solved but that doesn’t mean that plenty of 5^{th}-order polynomials*can*be solved, one example,*r*(*x*) =*x*^{5}- 1 can be factored, as*r*(*x*) = (*x*- 1)(*x*^{4 }+*x*^{3 }+*x*^{2 }+*x*+ 1), and 4^{th}-order polynomials like*s*(*x*) =*x*^{4 }*+**x*^{3 }*+**x*^{2}*+**x**+ 1**can*be “solved.” - Pieced through Joseph Liouville’s construction of a transcendental number, later typesetting, at this link.
- After my brother Marvin started it, decided to inherit his genealogy work. On https://www.ancestry.com, is located here. I descend from a few interesting people … all important, even several owned slaves, but they don’t define me, now.
- I spent near three years studying Russian in college,
and over three weeks in Russia July 2009. Before leaving and while
there read Maxim Gorki’s
*Twenty-six Men and a Girl*, and translated the story after returning. Also, another short story I translated from Russian, Mikhail Zoshchenko’s ultra-short story*Nervous People.*Both at this link.

*Mathematical field of topology: a Möbius strip*

*Galois
Theory, a tower of subgroups*

*Genealogy: Winnifred Jane Ulrich, also Ullrich, my mom’s dad’s mom; her life was 17 Aug 1875 — 5 Feb 1974. Born 102 years before my wedding day (August 17, 2002!), Barely remember her; she died when I was in sixth grade. Recall her as being a bit older, than this photo.*

*Getting married on her birthday was not remotely my or our intent; didn’t even know her birthday, until years later. August 17 is also my mom’s birthday; of this, we were aware.*

*Ovid*’*s Metamorphoses – great mythology!*

*Here *Daphne chased by Apollo* metamorphoses into a bay laurel tree. He clearly didn’t have her good health in mind, so, good riddance, if a bit expensive, for her.*

*Read this guy’s collected works a few ago – took over a year, but did it.*
