This #BlackHistoryMonth I’ve been looking at the origins of African American crafts. The pattern in the first picture is inspired by Kente cloth. The cube design is based on the zigzag pattern often seen in African art. #mathsky #mathart #mathematicalart

🌊 Our new Patreon-exclusive puzzle is inspired by Hokusai’s The Great Wave! Using a technique we call "flip cutting," it’s double-sided with pieces laser-cut from both sides for an extra challenge. Patrons get experimental puzzles like this 3x a year. Join us: patreon.com/nervoussystem

Although Differential Geometry (online shop) is my primary income, my mission includes education and outreach. The math blog connects shop designs to underlying mathematics, with pictures, animations, and what I hope are friendly explanations. diffgeom.com/blogs/about-... #MathSky #MathArt

A thumbnail-sized blossom from my neighbor's yard. UV light itself is invisible, but it excites the tissues in some plants to produce their own internal glow. The light is not merely reflected, but created by the plant itself. 𝘗𝘰𝘭𝘺𝘨𝘢𝘭𝘢 𝘹 𝘥𝘢𝘭𝘮𝘢𝘪𝘴𝘪𝘢𝘯𝘢 '𝖧𝖺𝗂𝗋 𝗅𝗂𝗄𝖾 𝖥𝗅𝗈𝖼𝗄 𝗈𝖿 𝖲𝖾𝖺𝗀𝗎𝗅𝗅𝗌'

A limited number of jewelry seconds at Differential Geometry need and deserve good homes, and are priced to sell with discounts of 40 to 60%. In most cases, a piece's contours diverge slightly from the mathematical ideal. diffgeom.com/collections/... #MathArt #MathSky #Jewelry

"Phosphene" is a simple truchet tile toy I wrote in 2012. Click a tile to rotate it a quarter-turn, or use the buttons at bottom to rotate specified groups of tiles; the array size (4x4-32x32) and several colors/tile patterns can be selected: diffgeom.org/software/Pho... #MathSky #MathArt #Truchet

Spent the morning photographing our Radiozoa jewelry…hoping to launch them tomorrow!

I’m so excited to share Radiozoa: a jewelry collection inspired by the microscopic skeletons of radiolaria. The forms are algorithmically generated and cast in sterling silver or brass from 3D-printed wax. I hope you love them as much as I do! available now: n-e-r-v-o-u-s.com/shop/line.ph... #sciart

Not math, but site (bsky) community: A mutual follower, active in #MathSky, who had written of race and safety concerns, vanished overnight. Can't know what happened without asking them, but on its face this is disturbing, and arguably should concern us all, now. Thoughts, advice?
