Although my online shop Differential Geometry is a primary source of income, I maintain (on a static html site) a list of other creators' mathematical online shops: www.diffgeom.org/misc/math_sh... I hope you will browse and support us all! #MathSky #MathArt #ITeachmath #SmallBusiness

Differential Geometry is an online shop and blog devoted to math appreciation, education and outreach. All designs I sell are my own. I invite you to drop by and browse! www.diffgeom.com www.diffgeom.com/product/post... #MathSky #MathArt #ITeachMath #SmallBusiness

I design and sell mathematically-accurate jewelry inspired by differential and algebraic geometry, and topology, and invite you to browse! www.diffgeom.com/product-cate... #MathSky #MathArt #Jewelry #3DPrinting

"Unbalanced" Positive-negative space is on the mind recently. Elsewhere, people turn to chatbots for love and spiritual guidance. (More in alt text.) #MathSky #MathArt

I'm continuing to try to revise this design....thinking about cutting it out of metal once I get a refined design. (do we think it's interesting enough yet to spend $$?) This is made out of 60 identical modules, cut out of cardstock. #mathart

Poster images at Differential Geometry often have pedagogical content. www.diffgeom.com/product-cate... This month I've been creating designs that are not necessarily pedagogical. Here, the real (bottom) and imaginary (top) parts of the complex fourth power. #MathSky #MathArt

Poster images at Differential Geometry usually have underlying pedagogical content. This month I've been working on prospective poster designs that are mathematical but not necessarily pedagogical. www.diffgeom.com/product-cate... #MathSky #MathArt #ITeachMath

Really impressed by the brilliant designs created by #TMIP25 participants at our Geometry, Code and #Embroidery workshop today with @philjemmett.bsky.social I'm running a free online introductory workshop 17th Sept 4–5pm. Registration & resources: www.warwick.ac.uk/turtlestitch #maths #computing

"An Invitation to Real Analysis" is shipping! A blog post for prospective instructors briefly explains motivations and choices, from definitions to terminology to notation: www.diffgeom.com/blogs/around... The publisher's page, linked from the blog post, has a sample excerpt. #MathSky #ITeachMath

Wishing a happy 83rd birthday to NASA mathematician and researcher Christine Darden, who specialized in the analysis of supersonic noise and research into its reduction. She was the first Black woman at NASA to reach Senior Executive Service status. #WomenInSTEM #NASA #MathSky 🧪🚀

a TON of fake accts on this site now, remember to vet info before re-bleating in a panic (understandable panic, and yet) case in point: this is just one acct that keeps getting called out for disinformation. plz stop sharing their shit

I design and sell mathematically-accurate jewelry inspired by differential and algebraic geometry, and topology. Pieces shown are still available. I invite you to browse, and to email if there are shapes you'd like to see! www.diffgeom.com/product-cate... #MathSky #MathArt #Jewelry #3DPrinting

A more formal snapshot/portrait of a commercially printed 3.5in (90mm) black nylon model of Costa's minimal surface. The contours on the planar end are artifacts of the SLS process, but visually pleasant and mathematically meaningful. #MathSky #MathArt #3DPrinting

Ta daaa! I give you the Lorentz Attractor thanks to the free pattern from #ThreadedTheorems and also @samjshah.bsky.social whose posted work I admired. #StemBroidery #MathArt #MathSky

A new very short blog post contains the preface for students from the book "Sets, Groups, and Mappings." My goal was to explain "isomorphism" (of binary operations) as a way of conveying the book's expository tone and pedagogical stance. www.diffgeom.com/blogs/around... #MathSky #ITeachmath

Why stop at code-drawing a single mathematical tower? I want a city! #MathArt

As for what is at stake, there is a saying (often attributed to Richelieu), "Give me six sentences written by an honest man [sic] and I will find therein the means to hang him." Right-wing legalisms may be sophistry, but that makes them no less deadly.

An oblique view of Trinity, a 3-1/2in (90mm) unpolished brass piece made in 2023 by Shapeways from an original design. This photo was a pleasant hard drive find. Although the piece is not visibly symmetric, there are curves I better appreciate now than 2.5 years ago. #MathSky #MathArt #3DPrinting

Since z = x+iy = x-i(-y), a complex number does not have a well-defined imaginary part. (!!) Does the choice of imaginary unit affect complex analysis? In retrospect the answer is clear, but it was also not my offhand impression. Read more: www.diffgeom.com/blogs/about-... #MathSky #ITeachMath

The plotting/drawing software ePiX is also suitable for laying out pieces for slotted models such as Pulse. www.diffgeom.com/products/pul... www.diffgeom.com/blogs/free-o... #MathSky #MathArt

While checking into the class action suit against Anthropic, I learned that Sets, Groups, and Mappings (2019), my one-semester book for an algebra-based intro-to-proofs course, is ... specially-priced: bookstore.ams.org/amstext-39/ #MathSky #ITeachMath

We saw the movie Network again last night and just now I learned youtube has been editing videos using AI without telling people. If you've never seen Network you should really see Network. One of the best written-, edited-, and directed satires I've ever seen and it is still SO relevant.

Now and again people ask how I create images and animations. The short answer is "Long ago, I wrote software for mathematically accurate plotting in LaTeX." Longer answers: www.diffgeom.com/blogs/free-o... mathstodon.xyz/@diffgeom/11... #MathSky #MathArt #ITeachMath

I only photograph quilts on the windiest days. Generative Threads Quilt 13/13. Designed with 13 year old code and handmade with love. 🖤 Credit where credit is due: my Processing + Hype framework started as a collab w/ Joshua Davis. Forever grateful. #generativeart #generativetextiles #genart

We've got 35 sets of these posters left. This project came from my evergreen frustration with our important messages getting trapped on social media algorithms. Good stuff for posting on your local community bulletin board, classroom, office door, etc! squidfacts.bigcartel.com/product/scie...

Personally, I gravitate toward T-shirt designs that are a little ... spatial. Symmetry (invariance under some group) is generally a plus. Browse designs: www.diffgeom.com/product-cate... A list of math shops: www.diffgeom.org/misc/math_sh... #MathSky #MathArt #ITeachMath

I played with paint today. The packing radii for n-dimensional spheres is $/sqrt{n} - 1$ and spiral of archimedes hypotenuses follows sqrt(n), so I subtracted 1 from each hypotenuse and then added color.
