Not going to be at Bridges this year but I did get a chance to visit Ireland (including Galway) earlier this summer. I hope everyone has fun at Bridges. And that the people going to MAA Math Fest in Boston stop by to say hi in the exhibit hall.

365 days in a row is (a) nice to celebrate and (b) a high note to end on.

Happy harvest time! First cucumbers and zucchinis of the year!

This Venn diagram is not complete. It is missing two intersections - yellow and cyan as well as lime and red. For four sets I suggest using the intersection of four ellipses like this. See www.bachelorprint.com/statistics/d...

A Venn diagram for four sets A B C D is best represented by four overlapping ellipses instead of circles.

Early voting starts Saturday June 13 in New York! We at @cquid718.bsky.social (The Central Queens Independent Democrats) are co-hosting weekend poll site visibility at Queens Borough Hall alongside Forest Hills Indivisible and @chuckforqueens.bsky.social. Saturdays and Sundays polls are open 9am-5pm

Thanks @bdlimm.myatproto.social for sharing our campaign. Melissa and I have set up a webpage at QueensAD28.org with more information about our campaign and the role of a district leader and a way for people to donate to our efforts.

I was part of the mass of people at the No Kings march in Manhattan, New York City. It was packed!

Out with my slatemate this morning collecting signatures to get on the ballot for district leader!

The #blizzardof2026 has begun.

Ready for the Blizzard Warning from Sunday into Monday! We'll see if it pans out.

Projected snow totals for the weekend snowstorm as of Saturday February 21. Expected snow totals in New York City are currently around 16 inches.

Excited to be part of this creative community of mathematicians and artists. It plans to be a wonderful and inspiring week at the Institut Henri Poincaré! #illustratingmath

Heading to the #MSCHE Conference in Philadelphia. Provost Patricia Price, Associate Provost Rebekah Chow, and I will be presenting "Accreditation for the Rest of Us" Thu 12/11 9am, where we share lessons learned over the past 2.5 years. @queenscollegecuny.bsky.social represent! Feel free to say hi.

Something like this. It would look really cool sitting at the top left of a website.

Awesome viz!

A 3D visualization of the mayoral vote. The height of each bar is the number of votes while the color of the vote corresponds to the percentage vote lead for Mamdani (blue) or Cuomo (purple). It looks very similar to a cityscape with skyscrapers over Manhattan.

I am so excited to vote for our next mayor, Zohran Mamdani! (And get the special Halloween sticker!)

Beautiful evening here in Queens.

On Friday at Noon (EDT) I am giving a talk in the New York Combinatorics Seminar. The title is: "Mathematical illustration through a combinatorial lens" in which I share my decade-long journey as a mathematical artist and jewelry maker and how it intertwines with my combinatorics research.

Looking forward to a week of mathematical illustration. Train travel is the best.

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!!

Getting excited for the Bridges fashion show tonight! On the runway will be the world premiere of my black and white rhodium plated knight's tour jewelry!

Shiny angular jewelry with black and white accents.

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.

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 @divbyzero.bsky.social for your talk this afternoon about folding paper to create a one-cut Einstein tile and for chairing the session!

We very much enjoyed @mathskath.bsky.social's talk at Bridges this afternoon!
