These art pieces are generated starting with a rectangle of given proportions and iteratively generating two smaller rectangles from it, using a simple procedure (which could be easily done with ruler and compass).
Rectangles are coloured according to their proportion and orientation, each piece with a different palette . No randomness here (as usual). Generated using #Python .

Instance of the procedure for rectangle ratio 16/15, warm colours.
Instance of the procedure for golgen ratio rectangle, in dark reds, violets, and dull blues.
Instance of the procedure for a square, with browns, greys, pinks, and violets.
Instance of the procedure for rectangle ratio sqrt(2), red, white and green colours.

These two art pieces are based on the deformation of a hexagonal tiling into a topologically equivalent "tiling" composed of parts of concentric circles, all parts having the same area (third image). Selecting one hexagon as the center, we transform it into a circle of radius 1. Next concentric circle will hold the 6 adjacent tiles as sectors of rings. And so on, the circle of level n will have radius sqrt(1+3·n·(n+1)) (difference of radius when n tends to infinity approaches sqrt(3)). This map can be coloured with three colours, like the hexagonal tiling. For the artwork, suppose each sector of ring is in fact a sector of a circle hidden by inner pieces. Then choose a colour and delete all pieces not of this colour. Two distinct set of sectors can be produced, one choosing the central colour, one choosing another colour. Finally recolour the pieces according to its size.

A while back, @gwenbeads posted about the book “A Stitch in Line: Mathematics and One-Stitch Sashiko” by Katherine Seaton, and it was so relevant to my interests I had to get hold of it. I’ve been working through it ever since, stitching the samplers and playing with the maths.

I’m currently paused at the end of chapter 8 as I wait for new thread (Retors d’Alsace!!!) to arrive for the next sampler. Here’s a photo of all my samplers so far, done on my hand-dyed muslin scraps; my plan is to patchwork them all together into a hanging once I’ve finished.

Gwen’s review of the book is in a paywalled journal, but she’s put a link to free copies (of the review, not the book) here: mathstodon.xyz/@gwenbeads/1140

Seventeen small-to-medium square and rectangular pieces of cotton fabric dyed in shades of pink, purple, and blue, laid out on a cutting mat. Hitomezashi designs have been stitched on them in coordinating colours: crosses, squares, and fractal-looking designs, some regular and some random.

Happy birthday to French mathematician, physicist and philosopher Marie-Sophie Germain (1776 – 1831), known as Sophie. She taught herself mathematics using books in her father’s library and by corresponding with leading mathematicians of her day, including Lagrange, Legendre and Gauss, initially using the pseudonym Monsieur LeBlanc. 🧵1/n

Linocut of Sophie Germain (a young woman in with a collar with bow, under a dark dress, with a ribbon tied around her neck, long hair with centre part, half tied up with a ribbon in her hair). She is printed in dark blue with her own words about Fermat's Last Theorem in her own script carved into her hair and dress). Behind her in lavender is a grid of Chladni figures.
