new blog post on Mrs. Perkins' Quilts

I am still figuring out an OEIS draft, but kinda wanna quilt more.
Rabbit Hole: Minimum L-seams
I was trying to write a post about art with squarable numbers, and so I thought quilting a Mrs. Perkins' Quilt might be a nice addition to the exploration. With 1500 words almost ready to hit send, I ...

For those of you that aren't sure whether it is a greater yellowlegs or lesser yellowlegs, just remember the greater yellowlegs eats the frog.

I have included a diagram with and without annotation.

I belief the latex is \gyl, \lyl

#birds #math #greaterthan #inequalities #frog #mathInTheWild
A greater yellowlegs stands with yellowlegs to the left with a frog in its mouth. A lesser yellowlegs stands with yellowlegs to the right without a frog in its mouth. both create angles with the reflections of their bodies and face away from each other. A greater yellowlegs stands with yellowlegs to the left with a frog in its mouth. A lesser yellowlegs stands with yellowlegs to the right without a frog in its mouth. both create angles with the reflections of their bodies and face away from each other. There are annotations in white making the two math symbols and labeling "greater", "lesser", and "frog" in cursive.

I'm going to run a group - Painting the OEIS.

Please share your favorite sequences and why. I'll share what art I do with any of them.

#Desmos
Description: A circle with nested curves larger on the lower right, smaller on the lower left and thin and stringy toward the top left repeated 4 times scaling smaller with each copy and alternating between blues and teals. The four-circle arrangement is then reflected over the horizon. There is gradient color with deeper colors on the curves and light colors on the stringy parts.

A bittern from the neck up with beak up so that the eyes are comically low. There is brown striping on the neck and bright yellow eyes

I apologize for my alt text not being emotion free - I can't help it.
Two bushtits sitting shoulder to shoulder cuddling on a branch facing away from the camera with the most adorable fluff and little tails. They are grey with a little brown on their tiny little wings, and the cuddle is so cute I could die. The branch they sit upon is curved and they face an grape leaf, but fig leaves are blurred in the background with a vignette.

hexagonally arranged knot coloring sheet with symmetric coloring and crossings and one part in the center miss colored from the rest as dark when the others are pink. the colors are muted tones rectangular arrangement of a celtic-like knot with symmetry in knots, but not in colors. a braid of crossing strands with various colors that weave under and over with muted tones. a circular braid of loops where some cross in and out and others cross few or not at all. muted tones.

Thank you! This collaboration is such a gift to students. The structure you built makes the puzzles even more accessible by reducing the notation and cognitive load (while keeping all the joy and surprise). Beautiful! #iTeachMath #MathSky

It turns out Weezer’s Sweater Song was about computation.
FIG. 4. (a) Diagram of knitted half-adder realized in our experiment. It adds two input bits, A and B, to produce sum bit, S and carry bit, C. The logic gates of NOT, AND, and OR are highlighted in green, blue, and red, respectively. (b) The circuit diagram of the half-adder illustrated in (a). (c) Experimental realization of the half-adder. The tags of the input and output bits are attatched to the yarn loop for a visibility. The tags correspond to the input and output logic values are released from the computer. (d) The half-adders after the computations for all four inputs, A= 0 and B = 0, A= 0 and B = 1, A= 1 and B= 0, and A= 1 and B= 1. All outputs are confirmed to be correct.
