Today's #Mathober Five Circle Theorem. Doodle, code, Desmos

Desmos: www.desmos.com/geometry/fxp...

p5: codepen.io/editor/fract...

five mushrooms grow above like looking up through a forest so that their caps centers are on the same circle and the intersections form lines that are a spiderweb with no spider. a banana slug climbs the one in the upper corner and it is all under low light with an almost new moon. the text says five circles cast a stellar web under a near new moon in a font drawn from slugs.

Mathober Day 7 - Five Circles Theorem

5 circles are drawn so that they intersect at 2 points, with 1 of those points lying on a central circle. Connecting the intersection points that do not lie on the central circle forms a pentagram.

Day 7 of #mathober is all about Five Circles, and I've picked my favourite five circles to showcase. Or are they all just the same circle...? PDF: https://katiesteckles.co.uk/mo7

A fairy ring of mushrooms in a forest at night with a sliver of a moon connected by a nebula cloud on the floor with a banana slug coming the the illuminated ring - almost like a campfire of light.

Mathober - Day 6 - Connected Topology

A connected topology describes a space where any two points can be travelled between without leaving the space.

This starts with a convex hull surrounding a region of points which shrinks inward.

2. How much did it change what the filter knew afterwards?

The distinction turns out to be quite useful.

#mathober continues, as it will tend to do, and I've done another tiny maths zine, this time on the topic of Connected Topology. How long will I continue? Who knows! I am tired https://katiesteckles.co.uk/mo6

already posted code, but here is today's #mathober doodle for inellipse:

#mathart #fungus #pnw #inellipse

a crescent-waning moon sits in a burn forest silhouette with a triangle shadow of leaning trees at the main center. Within the triangle the underneath of a chip cherry mushroom makes an ellipse just touching the triangle edges creating an inellipse. there are highlights where moisture catches the moonlight. A small banana slug moves in the shadows up a tree

Today's #Mathober inellipse. I am still working on the doodle, but here are coded ones - these took me longer than anticipated.

Slightly delayed due to not being near a scanner, here's yesterday's quick maths zine for #mathober, on the topic of Linear Recurrence! PDF: https://katiesteckles.co.uk/mo4

Mathober - Day 5 - Inellipse

Each triangle has an inscribed ellipse, known as an inellipse.

In this sketch, a Delaunay triangulation is drawn, along with the corresponding inellipses.

#mathart

A padovan sequence represented by spiraling triangles drawn as a frame with small yellow fungi tentacles coming out of the frame to make a slight spiral through the height along each line. There is a moon at 38% and a banana slug climbing down the frame. The drawing is mostly yellow on a dark blue background.
