I like to close #mathober with some calaveras to remember those we lost this year from the math community. Chief for me was the amazing Shelli Temple (druinok). www.tumblr.com/mathhombre/7... #mtbos

For #mathober day 27:bidiminished I tried for a Parabidiminished Rhombicosidodecahedron in Polypad. Will not fold :-( polypad.org/tjsbVJj9afVOVQ Diminished means substituting a regular polygon fo a feature like a cupola.

Today's Mathober - partial sum.

I also did a p5 sketch: codepen.io/fractalkitty...

#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.

Clemson has been designated a National Monarch Butterfly City, and there is a public art installation of 20 fiberglass butterflies all around town.

Look closely, one of them appears to have some hidden mathematics on its underside! #IllustratingMath #Mathober
Public art installation from the Butterfly Project in Clemson, SC Public art installation from the Butterfly Project in Clemson, SC. From the QR code: “…textile art to represent both our home in the Blue Ridge foothills and the end point of the monarch's sojourn in Central Mexico. The left wing is inspired by the Tenango, the traditional embroidery work of the Otomi people. The right wing shows a Cherokee seven point star quilt pattern, representing southern Appalachia's rich quilting history, as well as the indigenous influences upon the art form. In both cultures, such large and detailed textiles often involve family or community members working on a single piece together, making them symbols of cooperation and unity.” Public art installation from the Butterfly Project in Clemson, SC Public art installation from the Butterfly Project in Clemson, SC, with the butterfly lemma hidden on its underside!

I have to add this picture for #mathober today from a few years ago.

Rhombic tricontahedron and dodecahedron
A blue and white tricontahedron made of a plus shaped toy placed together linked to link held by a person with a green shirt with a house in the background. The sheep has blues with a white inside and lots of holes within the toy. A dodecahedron made from a plus shaped toy linked together with orange, then red and the pentagon’s are open showing and inner core with more black, white and orange

It's also somewhat transparently drawn in a lot of places - so I'm counting it for weird web October as well.

The mean of N points is sum(points)/N, but their median (known as the Fermat point in the N=3 case) is surprisingly difficult to compute!

The deviation between the two increases with the asymmetry of the triangle. When one of the angles is >120° the median clips to that vertex~ #mathober

The first day of the 6th year of Mathober!

Today's prompt is Link.

I will post on blue-skee and this blog post as the month goes on:

www.fractalkitty.com/mathober-202...

I might code something later, but not sure yet.

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.
