Almost at the end of #mathober but there's always time for an INDEFINITE QUADRATIC, which is today's prompt and here's a nice zine I made. Never heard of that meaning of "definite" before, but I guess it makes sense there'd be a term for it! PDF: https://katiesteckles.co.uk/mo27

just some dots on a line #mathober - because I did not have the energy for E8 today

The next #mathober prompt (see the full list at https://mathober.com) is CROSSED PRISM GRAPH, and these are a fun set of graphs with a nice definition and surprising celebrity member. I made a zine and a GGB! PDF: https://katiesteckles.co.uk/mo25

Today's prompt for #mathober is UNIMODULAR LATTICE, which has a surprisingly straightforward definition and some nice famous examples. I made a zine! PDF: https://katiesteckles.co.uk/mo26

Attempting to catch up with #mathober, here's my zine in response to the prompt for day 22, which is POLYLOGARITHM - hard to draw 4D plots but I've found some fun facts about it! PDF: https://katiesteckles.co.uk/mo22

Prompt 23 for #mathober is DEVIL ON TWO STICKS, which I didn't have a lot to say about but I've made a zine and a Geogebra and it's fun! PDF: https://katiesteckles.co.uk/mo23

After a frankly heroic catch-up effort, here's my third #mathober zine of the day, about MULTIPERFECT NUMBERS - including a diagram I came up with but that surely someone else has already used to illustrate this? PDF: https://katiesteckles.co.uk/mo24

multiperfect number today for #mathober Code: fractalkitty.org/e/day-24 Desmos: www.desmos.com/calculator/9... I found little emerging witches hats on my afternoon walk to sketch tonight.

Devil on Two Sticks! #mathober The first time I coded this curve was in 2021 when I was learning p5js it was day 18 - I've learned so much since then. I found a Devil's tooth on Mary's peak in a noble fir forest. Desmos: www.desmos.com/calculator/r... Code: fractalkitty.org/e/day-23

Slightly delayed as I've been under the weather, here's a zine for #mathober about PRIME RING. Looks like there's a few possible definitions out there but I like this one. PDF: https://katiesteckles.co.uk/mo21

#mathober for today - polylogarithm Code: fractalkitty.org/e/day-22 Desmos: www.desmos.com/calculator/o...

#mathober - Prime ring Code: fractalkitty.org/e/day-21 Desmos: www.desmos.com/calculator/c...

Today - #mathober is Nice vector field. I just made vector fields that are nice. Including some slime mold. + code: www.fractalkitty.org/e/day-20 + desmos: www.desmos.com/calculator/w...

Mathober Day 20 - Nice Vector Field A nice vector field is a smooth vector field whose flow lines form closed loops creating a periodic orbit. On a torus, these orbits can wind around the surface without intersecting. openprocessing.org/@speters/303... #p5js #mathober #mathober20

It's day 20 of #mathober, and I don't have the capacity today to research a new thing (NICE VECTOR FIELD) so instead I just built to a glorious pun #sorry PDF https://katiesteckles.co.uk/mo20

Today's #mathober - Orthic Triangles. Morel doodle and then some tedious Code: fractalkitty.org/e/day-19 and then a Desmos: www.desmos.com/calculator/l...

I've been at it on the Geogebra again for today's #mathober zine: it's all about the ORTHIC TRIANGLE and various other fun constructions you can define on a triangle, which is of course better when you can drag the corners around. PDF: https://katiesteckles.co.uk/mo19

#mathober 17: dimension invariance, a #mathcomic www.tumblr.com/talkingnumbe...

Mathober Day 17 - Dimension Invariance 3 curves, inhabiting spaces of 1, 2, and 3 dimensions, share the same intrinsic dimensionality: 1. Their appearance changes with the space, but their underlying dimensionality remains invariant. openprocessing.org/@speters/303... #p5js #mathober #mathober17

Day 18 of #mathober is all about BIFLECNODAL POINTS, and writing this made me straighten out some ideas I hadn't properly processed fully before. Also it's a flipping great word! PDF: https://katiesteckles.co.uk/mo18

Mathober Day 18 - Biflecnodal Point A biflecnodal point is a point where a curve crosses itself and both intersecting branches have an inflection point at the intersection. This sketch uses the formula k x^2 y^2 + y^2 - x^2 = 0 openprocessing.org/@speters/303... #p5js #mathober #mathober18

#Mathober today - Biflecnodal Point Code: fractalkitty.org/e/day-18 Desmos: www.desmos.com/calculator/6...

Dimension invariance for #mathober cabbage-leaf fungi today, I mean donuts, I mean coffee cups also code: fractalkitty.org/e/day-17 desmos: www.desmos.com/calculator/3...

Here's today's #mathober zine, which is about DIMENSION INVARIANCE. Or is it actually about homeomorphism? Maybe those two things are homeomorphic (no, they are not). PDF: https://katiesteckles.co.uk/mo17

#mathober today - isochronous curve code: codepen.io/editor/fract... desmos: www.desmos.com/calculator/1...

#mathart doodle for #Mathober 13: The standard map www.tumblr.com/mathhombre/8...

looking at today's #mathober - found this: youtu.be/eBc827pwKf0?...

Irredundant! #mathober code: codepen.io/editor/fract... Desmos: www.desmos.com/calculator/1... (just three dots and two lines)

It's day 15 of #mathober! Today's prompt is IRREDUNDANT, which is a very silly word that has a meaning in graph theory and I wrote a zine about it! (sorry, my pink pen looks a lot brighter in real life) PDF: https://katiesteckles.co.uk/mo15

Just before bed, another quick #mathober zine for today's prompt, ICOSITETRAGON. So many sides! PDF: https://katiesteckles.co.uk/mo14

Mathober 14 - Icositetragon An icositetragon is a 24 sided polygon. Who knew? openprocessing.org/@speters/303... #p5js #mathober #mathober14

Out on the road yesterday so here's a slightly delayed #mathober Zine about the Standard Map! Also it took me ages to colour in PDF: https://katiesteckles.co.uk/mo13

Today's #mathober - Standard Map! Code: codepen.io/editor/fract... Desmos: www.desmos.com/calculator/8...

Yesterday's #mathober prompt, PARABOLIC ROTATION, led me to a fun yet mysterious function! (No scan just yet as I'm on the road, but will add links later)

Late to the #mathober party (but the great examples being shared so far have inspired me). Thanks to @fractalkitty.com for keeping this rolling! Here's my attempt to animate the Standard Map (in #GeoGebra) for Day 13.

#mathcomic for yesterday's #mathober, the lovely #mathhistory problem of points www.tumblr.com/talkingnumbe...

Reciprocal Prime Constant today! #mathober code: codepen.io/editor/fract... desmos: www.desmos.com/calculator/h...

I continue to find a bit of time each day to produce a zine for #mathober! Today's is about the Reciprocal Prime Constant, which is nicely related to a thing I already knew about, but M is new to me. PDF: https://katiesteckles.co.uk/mo12

Mathober Day 12 - Reciprocal Prime Constant The reciprocal prime constant, or Merten's constant, is the sum of the reciprocal primes minus ln(ln(n)), as n approaches infinity. Merten's constant has an approximate value of 0.2614972128. openprocessing.org/@speters/303... #p5js #mathober #mathober12

I found a big sulfur shelf at the park yesterday to doodle today's #mathober - Problem of Points Code: codepen.io/editor/fract... Desmos: www.desmos.com/calculator/i...

It's the 11th of #mathober and today I have made a little zine about the Problem of Points, which I'd never heard of but has quite a cool story! (PDF to follow later when I'm near a scanner.)
