Was asked to do some light boards for a friend's droid.

Had a great time this weekend rolling around #pinewoodstudios with R2 for #futuresfestival.
Even if the droid transport was less than glamorous.

Hope I did this right.

Thanks @dpoulsen for the links and inspiration!

Today's #Mathober is "Jacobian." The Jacobian determinant helps us find how areas of rectangles are transformed when mapped into a new coordinate system. I used the Jacobian determinant to figure out how to cut an onion so that the pieces are most uniform. The math has been featured in the New York Times and, recently, a great article by the Pudding.
When I published all the nitty-gritty mathematical details of the method in Mathematics Magazine, I titled the paper "How to Cut an Onion Optimally: A Love Letter to the Jacobian" because of how central the Jacobian determinant is to ask the calculations, including the evaluation of some gnarly integrals. If anyone wants access to the article, I'm putting my gift link in this post (limit to first 50). https://www.tandfonline.com/eprint/AUGKH2EDWISRJTQUMKJJ/full?target=10.1080/0025570X.2025.2521248
For Mathober, I constructed a representation of an onion and cut lines using straightedge and compass. Then, I painted the cells using alcohol markers. Finally, I free-handed the constructed lines using black marker. I like the effect.
