Website activity diary 2017

Another quiet year, focus derailed by emotional turmoil. I did at least (eventually) work out how to configure ssh correctly to restore communication between my public web server and the version-controlled source repository in which I prepare what I write. Aside from a plethora of tiny typo fixes and kindred tidy-ups, along with minor additions to my time-line and pages on the scale of things, here's what git log tells me I got up to:

Modular doodles: I poked around my beginnings at a treatment of modules over a ringlet, notably adding consideration of anti-linearity for compledified ringlets.
The Hilbert space formalisation of Quantum Mechanics: I wrote a little more, mostly about the algebraic formalism it requires, barely touching the actual physics.
Altruism and evolution: I added some minor observations on the evolutionary benefits of altruism.
The three centres of a triangle: Another classic piece of Euclidean geometry.
Isosceles triangles: A rough account of one of the most basic pieces of Euclidean geometry, including the relationships between circles and triangles inscribed within them.
Squaring polygons: A look at a difference of two squares reveals a way to construct, for any polygon, a square with the same area.
Pythagorean proofs: I separated out most of the proofs from the general discussion of Pythagoras's theorem, keeping just my own proof on that page and elaborating on it.
Equilateral triangles and related rectangles: The box in which corner angle trisectors bounce around particularly neatly.
Refining Life: My implementation of Conway's game of that name, to be specific; the controls are a little more helpful now, in a few minor ways.
Rational physics: Some stray thoughts on how theories of physics might use rational numbers, and rounding within them, to model some of what we see in physics.
Orderly arithmetic: More thoughts on the relation between ordering and arithmetic.
Cauchy limits: A partial treatment of convergence.
A ringlet modulo an ideal: Made a start on studying one of the details I skipped over in my earlier treatment of my adaptation of ring theory. In particular arithmetic cycles are an example of this.
Complexifying a ringlet via polynomials: A second way to get at the complex numbers, for a general ringlet; polynomials modulo power(2) +power(0).
Earlier history: 2016, 2011–2015, 2010, 2009, 2008, 2007, 2006.
