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).
