Front of tree-like being made of crochet and two tones of brown. It’s on a bed of green yarn on the table. There are two short legs and arms with branches on the head and a nose up high.

I may have dug through all of my reflection photos until I found the sigma I was looking for.

Can you find the Sigma?
#mathober #mathober2025

Today is notation.

For code - I did Q.E.D: https://codepen.io/fractalkitty/pen/wBMJVpp??editors=0010
A brewers blackbird with a black iridescent body and yellow eye on a twig in the water. The legs reflected make a sigma symbol. The water is blues and browns smeared color with a slightly smeared reflection.

Today's Mathober - partial sum.

I also did a p5 sketch: https://codepen.io/fractalkitty/pen/ByjWppj?editors=0110

#mathober #mathober2025 #creativecoding #birdart #mathart #mtbos #cantor #partialsums
A pileated woodpecker sits at the base of a tree that has a cantor set excavated, where the lines for the cantor set ar vertically drawn by long excavation trenches. The bird has a bright red cap and is making eye contact with the viewer. There is partial bark at the edges of the tree and grass on the ground.

Today's mathober is "digraph sink"

All these paths seem to lead to a flicker.

I did a p5js sketch as well: https://codepen.io/fractalkitty/pen/qEbRMWE??editors=0011

#mathober #mathober2025 #birds #birdart
A flicker perches on a birch branch that splits of into the sunlight so that all branches lead to the flicker looking at the sun. There is a circular smeared sky that goes from light to darker edges.

Not sure if I'll get all my mathober done today. I took a moment to write and process:

An outtake:
A bushtit clinging to a branch sideways with one wing out and a very awkward position with a blurred yellow background and twigs. This little bird is all gray with a darker face and wings and lighter tummy.

#mathober today is Strongly

I went with a strongly regular graph after going back and forth on what to do.

#mathober2025 #birdart #mathart #mtbos #math #birds #pnw

I am hoping to do birds I've seen in my yard for the month - hoping that will work.
A pentagon made of a continuous bent twig lined with lichen. There is rotational symmetry and about halfway along each segment of the pentagon side, there is gathered bunch of lichen and moss with a bush tit on each one. The background goes from a pale yellow to a muted slate blue with a feeling of smeared clouds int he texture. The bushtits have silver lining.

Polyhedron - #mathober day 3

#polyhedron #mathober2025 #mtbos #mathart #pnw #birds #birdart
A digital sketch. A black-capped chickadee pecks at something in a crack on a boulder ther shap of a dodecahedron in a boulderfield. the boulder has some moss, ferns, and fungus on it, but the rest in the field do not. Only the boulder that the chickadee is on is in focus.

Silver lining
A bushtit, facing to the left looking up on a branch with moss and liking where the bird is darker with bright white feathers at the edge. There is a blurred forest background and vignette.

I spent way too much time on rabbit holes today (associahedrons), so just a simple sketch for today:

I will doodle a bird soon, but might be a day.

Today’s #mathober is polyhedron. Which is your favorite? Why?

I will start my sketches later- any suggestions or takes on the prompt are welcome. What Pacific Northwest bird should be next?

Day 2 - Deviation

I went with a geodesic deviation.

A redbreasted nuthatch stands on an acorn with a bead of water on its beak watching two other drops of water run down the acorn in longitutinal paths - deviating from each other on the surface. a blured forest background is in the backdrop.

Love this!

Also adding #mathober hashtag

The spelling of mathober has been up for debate since the beginning.

I guess it's actually appropriate for today's #mathtober, since it turns out that the thing that the integral should be is related to the self-linking number
Mathematical text ending up discussing "The knot-theoretic expression" that is the formula for an expectation value for a quantum observable, giving the "self-linking, or framing, number"

Mathober Day1 - Link

stream of consciousness code - so it's a mess

#mathober #mathober2025 #codepen #p5js #creativecoding #proceduralart
Six rings in a circle with a single link holding them together in the middle - there are gradient colors for each ring all in a slate-gray color. there are radial gridlines in the background and static feels in the sketch.

The first day of the 6th year of Mathober!

Today's prompt is Link.

I will post on mathstodon and update this blog post as the month goes on.

https://www.fractalkitty.com/mathober-2025-sketches/

I might code something later, but not sure yet.

#mathober #mathober2025
Six rings held togher by a single ring going over and under, where each ring is a circular tree branch with lichen, moss, ferns, and mushrooms growing off. Everything is radially symmetrical so that the six rings have repeated growths and lighting. On each ring there is a brown creeper facing clockwise with a dark speckled top and white brest with a curved beak. it faces a tiny mushroom. the background goes from a light yellow to dark slate blue from the off-center center of the radial sketch with a smeared cloudy feel to it. in the lower corner is a signature S with a period.
