This afternoon was the "Hands-On Activities" portion of the conference. I brought the supplies (150 laser-cut pieces of wood, 1000 yards of yarn, wood glue, and 50 binder clips) to make a giant cardioid and a giant nephroid. It was fun, and I think they turned out great.

Il y a 31 ans, à Marseille, un colleur d’affiches du FN tuait d’une balle dans le dos Ibrahim Ali un minot de 17 ans qui courait pour attraper son bus et rentrer chez lui. L’extrême-droite tue. Et a toujours tué

Trompe l'oeil / détrompe l'oeil. Finished. Ouf

Acheté il y a 34 ans en Chine. Changé les piles. Chapeau !

Progress of work in progress

A new concept : the 'detrompe l'oeil'. Building a real object from a trompe l'oeil painting. Work in progress. And I the realize I missed the recursive trompe l'oeil.

Over my years in academia, I wrote or helped create a variety of free online mathematical materials. Phosphene is a meditative geometric solitaire that runs in a web browser. I hope you and your students enjoy the software! Read more: www.diffgeom.com/blogs/free-o... #MathArt #MathSky #ITeachmath

Some news from the Curiosity Cabinet Framed in a Rectangle Itself Framed only with Squares. (#CCFIARIFOWS) Maybe I will postulate with it to the Bridges Conference exhibition...

I wrote this song on Saturday, recorded it yesterday and released it to you today in response to the state terror being visited on the city of Minneapolis. It’s dedicated to the people of Minneapolis, our innocent immigrant neighbors and in memory of Alex Pretti and Renee Good. Stay free

The world’s first pocket music player was this tiny Mikiphone from the 1920s. A gramophone like machine. www.invaluable.com/auction-lot/... Invented by Hungarian siblings Miklós and Étienne Vadász though produced in Switzerland. It could fit in a pocket, though only played 10” records.

Great! ☀️

No joke.

J'ai demandé "La guerre de Troie en pâte à modeler flashy". J'aime bien.

A horizontal brass #sundial, made by M. Pigeon, Lyon, France. The latitude can be adjusted 40-60 degrees, with the bird’s beak. 3 sets of hour lines. Dated 1770-80. Dimensions 8.9x5.5cm unfolded. 🔭 🧪 #sundialSunday

Escale à Saint-Quay-Portrieux sur les traces de Paul Signac, qui a peint en 1888 la "Dame de fer", un phare métallique installé en 1868 et fabriqué (comme les phares des Roches Douvres et Amédée) par l'atelier parisien de François Rigolet: 👇 📷 @gardien2phare.bsky.social 🎨 Kröller-Müller Museum

In 1943, during the German occupation of Norway, Norwegian author Knut Hamsun gave his Nobel Prize (Literature) medal to Joseph Goebbels, Hitler’s Minister of Propaganda, as a gesture of political loyalty.

This is your reminder that Hungarian-Jewish scientist George de Hevesy dissolved two Nobel Prizes in aqua regia to keep them out of the hands of the Nazis. He then left the dissolved solution on his shelf and fled to Sweden. (After the war he un-dissolved the gold and the prizes were re-cast.)

As usual, everything you need is available on my website for download. Print & cut out the wheels and follow the instructions on the 12-page PDF. I wrote a user guide in french, and also one in english. www.astrolabe-science.fr/maquette-ast... 5/5

C'était peut-être pas une bonne idée de vouloir faire un arbre généalogique de la mythologie grecque. Je suis encore loin d 'en voir le bout. Mais c'est un bon exercice de dot/graphviz. Le source dot et le pdf sont dans un git : github.com/francescodec...
