Here's your chance to learn about some #illustratingMath while going through the lovely #MathArt by @mathzorro.bsky.social. Give the talk a watch!

For all the #textile #art fans! 😍

I was delighted to learn that this #watercolor and pigment ink #painting won Best Photograph, Painting, or Print at the MAA Mathfest Art Exhibit 2025.

I can highly recommend the #pod. Cool and insightful conversations and great content overall, featuring @steckl.es and @peterrowlett.net among others.

Inspired by @anniekp.bsky.social and @aliensunset.bsky.social, I created this beautiful piece of mathematical art! Hitomezashi stitching!

A split screen shows a person at a podium and a slide with a diagram of a "Flat Klein Bottle with curved crease origami," which is a grid-like, cylindrical shape that has been bent into a V-shape.

A split screen shows a speaker and a slide with two identical 3D renderings of a grid-like, folded geometric object, a "flat Klein Bottle."

A person presents with a split screen, showing them and a slide featuring a complex, folded geometric object with a title "A Piecewise Smooth Isometric Immersion of a flat Klein Bottle."

A person is giving a talk, with a split screen showing them and a slide with two images of a transparent, cylindrical shape made of crisscrossing blue and white lines.

The second talk is by Stepan Paul, who tells us about "Topological Origami: Beyond the Paper Donut."🍩Flat tori are known, but what about a flat Klein Bottle? Stepan shows us a first prototype (that fails at six points ) as well as a corrected model that's on the arxiv arxiv.org/abs/2504.08826.

A person is giving a talk, with a split screen showing them and a slide with a hand-drawn diagram of a perfectly smooth torus with the title "The Perfect torus?".

A split screen shows a person presenting and a slide with a hand-drawn diagram illustrating the difference between "Mathematical Precision" and "Mathematical Imprecision" when constructing a torus.

A split screen shows a speaker and a slide with a hand-drawn diagram explaining the "Gauss map/Normal map," using a torus and a sphere to illustrate the concept.

A person presents with a split screen, showing them and a slide with a sketch of M.C. Escher's "Hand with Reflecting Sphere" and the word "Torus" written below it.

Starting the #illustratingMath talks at the @icerm.bsky.social today is Elliot Kienzle, who aims to settle the question how "To draw a torus." Like all good answers, his is based on differential geometry, taking the geometry of the torus into account when drawing. And Escher's there, too😄

Today, the one-week #illustratingMath workshop at @icerm.bsky.social starts. It is a week, packed with great talks on #images, #animations, #textiles, #sculptures, #dance, and #3dPrinting. All talks are being live-streamed, so go check out the schedule at icerm.brown.edu/program/topi... and join in!

As I head home from #MAAthFest, enjoy these wonderful pieces in the Math Art exhibit including pieces by @gwenbeads.bsky.social and @gelada.bsky.social

This is a photo of a tree that fell on campus during a summer storm. I wonder if there's an interesting conversation we could have with multivariable calculus students about tree rings. Tree rings are level curves. What's the function? What does the gradient vector tell us? Etc.

Screen with a quote referencing Kenneth Martin - "Oh all right, then I have made a mistake" when someone else referred to an artistic liberty (an imperfection) he had made in an illustration.

Thanks @gelada.bsky.social for your thought-provoking talk this morning! I appreciated many parts including where you discussed two different ways in which mathematical artists might approach artwork - create rules that must be followed to make art or use math as inspiration in the artistic process.

2nd day / 1st keynote / Bridges #Mathart is by @gelada.bsky.social, speaking about "Genuine Pretending: A Philosophy for Mathematics and Art." He shares with us what good comes out of following one practice (e.g. #math) as if it were another (e.g. #art).

2nd afternoon session of the Bridges #MathArt conference today: Mrinal Dhume and I conducted the workshop "Exploring Math Illustrations: Draw, Deduce, Discuss!" A game of pictionary encouraged participants to create and discuss math illustrations.

The show went great! It was so nice to be able to share the pieces with everyone. Lots of excitement and enthusiasm for the designs. And everyone else's work was amazing!!

Tuesday Night = Fashion Night💃🕺at the Bridges #MathArt conference. Participants double as models, showcasing the latest #MathArt fashion and jewelry pieces on the runway. From earrings to magnificent dresses, we got to see it all. Overview at gallery.bridgesmathart.org soon™️.

The last day of the Bridges #MathArt conference is also the last day to visit the #art exhibit of the conference. Luckily, all artworks from this year's conference (and all artworks of prior exhibitions) can be found freely accessible online: gallery.bridgesmathart.org/exhibitions, check 'em out!

* We will find out in September if the project makes it into the Paris exhibit

First keynote this morning at the Bridges #MathArt conference is by @alisonmartin57.bsky.social, speaking about "Transforming 2D Materials into 3D Objects: Flexing and Stretching the Rules." Using bamboo as the material, Alison creates intricate weavings.

It was a great first day of the Bridges conference. Rinus Roelofs gave the opening plenary talk about duality and polyhedra. Outside the room, there were some examples and build-your-own objects. Outside the building was one of his sculptures (in photo: Chaim Goodman-Strauss and Edmund Harriss.

First keynote of the Bridges #MathArt conference is by Rinus Roelofs, speaking about "Duality: Connected Structures". In an intricate series of animations and models, Rinus investigates unfoldings of polyhedra & the relation to their duals.

The second keynote of the Bridges #Mathart conference is by Micky Piller and Kristoffel Lieten, speaking about "Eindhoven and Escher’s Connection with the World of Mathematics." They are emphasizing the augmentation of reality by M.C. Escher in his works.

Getting @hanusadesign.com jewelry ready for @bridgesmathart next week!

Luke Skywalker himself, Mark Hamill, stopped by MoMath for some math fun! He rode the square‑wheeled tricycle and chatted with MoMath’s own Cindy Lawrence about the beauty of math. Catch him as a math-loving grandpa in The Life of Chuck www.newyorker.com/magazine/tru...

Thinking about upgrading this to include "Normalize giving students problems they don't yet have the tools to solve."

Being able to recognize that is a very important, and under-valued, skill.

So excited to share a BRAND NEW episode of Relatively Prime!

This one is a conversation about funding in mathematics with @mathprofcarrie.bsky.social, @drew-lewis.com, and Jude Higdon from @qside.bsky.social

You are right, though I could claim the flip is a rotation in 3d ;) looks great!

It is fun to start on gridded paper you can build a large top level and then start to sub divide, though you lose the grid thanks to the rotations the sides are always rational so you can set up a ruler on pints further out.

Note this is not the pinwheel, and will have only finite orientations. To make the pinwheel you need to rotate the rectangle inside 180 degrees.
