Hey, @rantonse, here's another work of art you inspired!
Tim Chartier@timchartier

Enjoying @hackingmath's book "Math Adventures with Python". Re-wrote the code to use matrix rotations given I speak so much in the context of linear algebra. Here's what I made. Hope I didn't wake the neighbors with my cheer when I got it to work!!!!

Mathematics. Visualizations of 8 different ways of shuffling 64 cards. The horizontal lines of dots represent the particular orders of the cards throughout each shuffle. The vertical curves represent paths the cards take from start to finish. Source: bit.ly/3BCOO5R

Alright... Let’s start with the book stuff, then (hopefully) get on with some math art stuff!

Hello, Twitter/world! Long time, no see. There is a voice that tells me to tweet more — and share more stuff. 👀

CANS OF WORMS How many ways can you pack N worms of length N in an NxN square grid? Invariant to rotation and reflection, the sequence as N increases is: 1, 1, 3, 39, 935... That sequence doesn't seem to be in the OEIS. Here are the 935 arrangements for N = 5.

@graveolens Wow, yeah! What would that look like? Similarly, I have imagined a contraption with beads on wires.

@rantonse reading through /Illustrating Mathematics/: imagine that each of the filaments in the 3d-printed card shuffling permutation is a wire and carrying some current: what would the electric field look like in space as the intensity and direction of that current changes?

All 49 ways that 6 circles can be nested, drawn with an even-odd fill rule.

@mathzorro @ICERM Not sure, but I think doing it by circle inversions is a good way. These ones are much more random, though.

It’s circle packing week at @ICERM. So much circle. ⃝ Be aware if you have trypophobia.
