#illustratingmath — Public Fediverse posts

Friday, May 8, we'll have the next #illustratingMath seminar online devoted to "Illustrating Tilings". Chaim Goodman-Strauss will give the main talk, flanked by Show & Ask of Evelyn Sander and Prajwal D'Souza. We start at 9am Pacific/12pm EST/6pm Europe. See you then!

Before looking at today's second day of the third #illustratingMath workshop at the Institut Henri Poincaré, I would like to share some of yesterday's results. Here are two images by @bernatree and @henryseg, respectively, using Voronoi cells for visualization. (1/3)

The afternoon was devoted to hands-on activities. Here are example pictures from a discussion on #illustratingMath in the classroom, a short course on learning how to draw #math, a work group on visualizing the p-adics, and a work group on visualizing ideal class groups. (2/2)

Yesterday, we kicked off the third and last #illustratingMath workshop at the Institut Henri Poincaré, dedicated to "Integrating Research and Illustration in Number Theory." In the morning, we heard four great talks. Here are Roice Nelson's @roice3 visuals: https://roice3.org/paris2026/. (1/2)

Tomorrow, on Friday, the 13th, join us for the second "Live from the Institut Henri Poincaré" #illustratingMath seminar online. You will get to hear what people have been working on during the current trimester program. We start at 9am Pacific/12pm Easter/6pm EUR. See you then!

The International Day of Mathematics (IDM) is approaching fast (March 14th / Pi-Day / Tau over 2 day). If you want to do some #illustratingMath in preparation for that, the organizers have just released their "color them yourself" posters: https://www.idm314.org/decorate#posters. Please share your results!

Here's a sneak peek from the #illustratingMath #shortFIlms screening, a video by @henryseg: https://youtu.be/g3X0d5NUjjA. (3/3)

In the afternoon, there are two screenings of #illustratingMath #shortFilms. A highlight is the movie by Alba Málaga (https://albamath.com/en/about) about folding a flat torus (which we all get to do while watching the video). The Q&A with the creators is super insightful. (2/3)

On today's 4th day of our #illustratingMath conference on "Bridging visualization and understanding in Geometry and Topology" at the @inhenripoincare, we hear talks from Thomas Fernique, Sofia Lambropoulou, and Lou Kauffman (online), touching on tilings, braids, and more. (1/3)

3rd day of our #illustratingMath conference at the @inhenripoincare - a short day with 3 talks. Samantha Fairchild, Mélanie Theilière, and Martin Traizet speak about their respective views on surfaces: how to compare them, how to embed them, and how to visualize them, of course.

On the second day of our #illustratingMath conference on "Bridging visualization and understanding in Geometry and Topology" at the @inhenripoincare, we hear from Claire David and Aurélien Alvarez. Next to some lively discussions, we also take our conference group photo. (1/2)

In the afternoon, we close with an exhibition of various #illustratingMath objects. The last set of objects, laser-carved into plexiglass, can be explored interactively here: https://lael.dev/billiards. A great way to end the first day and to kick off this conference week! (2/2)

This week: Second conference of the #illustratingMath trimester at @inhenripoincare titled "Bridging visualization and understanding in Geometry and Topology." Talks are by Hugo Parlier, Érika Roldán, and yours truly. Play with Hugo's app here: https://quadratis.app/playPuzzle.html (1/2)

Another highlight from the #illustratingMath trimester at the @inhenripoincare this month was a visit to the @palaisdecouvert. We had a great time with Robin, who showed us the different items from their mathematical cabinet of curiosities. Visit them if you have the chance!

Finally, a great tradition of our #illustratingMath events are the "Show & Ask" sessions, where speakers can show some of their illustration works and can ask the community for feedback, help, or advice. Of course, we are also running these on a weekly basis. The first one featured, among others, @Gelada. (6/6)

There are many regular activities running during our #illustratingMath trimester, including a #VR working group, a "Math in the Web" group, and a Shadertoy group. One of them is the weekly Drawing Club that is devoted to physical and digital drawings to visualize #math. (4/6)

An important part of the trimester is our weekly #illustratingMath seminar. The first three editions were given by Chaim Goodman-Strauss, Aaron Abrams, and @henryseg We heard about geometric constructions, visualizations of configuration spaces, and soap bubble #math. (3/6)

Things have been rather busy at the #illustratingMath trimester at the @inhenripoincare for the last two weeks. A number of illustration projects have been started, and the first intermediate results are looking promising. I'll share some highlights in this thread. (1/6)

The final session is dedicated to "Steps forward" for the field of #illustratingMath. What are the tangible next activities that we can pick up as a community? Suggestions include a dedicated journal, a tool collection, and an online archive, among others. (3/4)

Friday was the final day of our "Rigorous Illustrations" conference at the Institut Henri Poincaré (@inhenripoincare). First, we heard results from the working groups, some in the form of theater performances, some with hyperbolic mind maps; all concerning how to move #illustratingMath forward. (1/4)

Before going into the group discussions, there is the second-to-last #art critique session of the conference. Today, we get to look at and discuss some art by Steve Trettel, Elliot Kienzle, Jayadev Athreya, and Sam Fairchild. All beautiful examples of #illustratingMath. (3/3)

After looking at some lovely small #illustratingMath models during coffee, Glen Whitney continues with his talk on building "Rigorous Sculptures". Finally, Hortensia Soto delivers the capstone lecture on "Rigorous and Flexible Illustrations". A nice round-up of the talks. (2/3)

Today is the fourth day at our "Rigorous Illustrations" conference at the Institut Henri Poincaré. We take a look at #illustratingMath in Education with talks by Zsolt Lavicza (Technology), Stacy Brown (Geometric Proofs), and Greisy Winicki Landman (Role of Visuals). (1/3)

In the afternoon, we continue with the second "Art Critique" session of the week. This time, @henryseg, Stepan Paul, and @mathzorro present their #illustratingMath works and let the audience critique them. Finally, we round things off with more group discussions. (2/2)

Second day of our #illustratingMath workshop on "Rigorous Illustrations" at the Institut Henri Poincaré. In the morning, we heard from Shadab Tabatabaeian on cognitive effects of proofs, Elliot Kienzle on big vs. small #math, and Frédéric Brechenmacher on model history. And during the coffee break, @mathzorro showed his amazing #mathJewelry collection. (1/2)

We close the day with a groupwork session. The task is to derive questions on how to advance the field of #illustratingMath. Some examples: What are illustrations? Where to publish them? How to judge their quality? How to improve an illustration? Should there be a journal? (4/4)

In the afternoon at the Institut Henri Poincaré, we start with an introduction by Jean Schmitt on how to run an "Art Critique" session. Bravely, Gabriel Dorfsman-Hopkins and @Gelada then provide their #illustratingMath works as examples to be critiqued. (3/4)

This morning, talks are given by @Gelada (Why rigorous illustrations?), Robert Ghrist (Illuminating impossible objects), Pierre Arnoux (Counting the dots), and Ingrid Daubechies (Illustrating the development of wavelets). An amazing gallery of #illustratingMath. (2/4)

Tuesday afternoon was hands-on at the FabLab: In three rotating courses, we got to explore working on the 3D printers, the laser cutters, and the vinyl cutters. Of course, we had to produce some first #illustratingMath objects. (3/4)

This was the first #illustratingMath week of our trimester, "Illustrating as a mathematical research technique" at the Institut Henri Poincaré in Paris. (https://indico.math.cnrs.fr/event/13123/overview). We had a great first week. Here are some highlights (1/4).

Final day of the #illustratingMath graduate school at @_cirm wrapping up the mini-courses #CindyJS / #Shadertoy with circle inversions and ray tracing. A huge thanks to the teachers: Tim Reinhardt, Michael Martin Katzenberger, @Chaimgoodmanstrauss and @stevejtrettel (1/4)

For the fourth #illustratingMath day at the @_cirm graduate school, we continue the mini-courses. In the #CindyJS course, we consider domain coloring to visualize complex functions. In the #Shadertoy course, we solve some PDEs and then render the game of life. (1/3)

On day 3 of the #illustratingMath graduate school at @_cirm we continue the two mini-courses on #CindyJS and #Shadertoy. In the former, we learn how to draw conics (and how to draw them well). In the latter, it's all about hyperbolic tilings. (1/3)

Next is Olga Paris-Romaskevich, who brings to us a "Mathematical utopia in the dystopian times: Streetmath, #Math girls, and MATHEMATIKA." All three projects are amazing examples of mathematical #SciCom projects, executed by Olga, and spreading the fun of #illustratingMath.

#Diagrams help us when it comes to #illustratingMath. A recent @nature article looks at the history of #venn diagrams and how they blend logic with geometry. Find the full article here: https://www.scientificamerican.com/article/venn-diagrams-history-and-popularity-outside-of-math-explained/. Do you have a favorite (Venn) diagram?

Want to play with folded galleries in Coxeter groups?
Here's a cool tool to have a look at shadows in Coxeter groups. Programming this tool was part of a Bachelor's thesis I've recently supervised. I could not be happier with the final result!
