I created this logic/grid deduction puzzle several months ago just to try out vibe coding. I created it for myself and have been enjoying playing it, so I thought I'd share it more widely. I call it Daedalus' Labyrinth. https://divisbyzero.github.io/Daedalus-Labyrinth/
Each segment in the grid must either become a wall (a "hedge") or be removed. Numbers at the intersections indicate how many hedg

The proceedings for the Bridges 2026 conference in Galway (August 4-8) are out! I'm very excited to go. My article in this volume is an update of an older article I wrote: "A New Method for Creating Impossible Cylinders" https://archive.bridgesmathart.org/2026/

A benefit of having tenure and being at this stage in my career: spending days working on a problem, forming conjectures, finding connections, making discoveries, and proving results, all while not ruining the fun by doing a literature sea…

It is definitely worth watching this entire video! My friend and colleague,
David Jackson, shows how you can "hear light"! (It is also fun to see cameo appearances of other friends, colleagues, and students who are wowed by this effect!) …
On a whim, I asked Claude to make one of those D&D alignment charts filled with historical math figures. Here's what it gave me. I then asked it to redo the activity, but to add some diversity—women, non-Europeans, etc. What do you think?

The angles of a triangle add up to 180°.
If, instead, we do the following to each digit, d^(9-d), and then add, we have exactly four fixed points: 0, 1, 8, and 1074
1074 → 1^8+0^9+7^2+4^5 = 1074.
If we take 0^0=1, then by raising each digit of a number to itself as an exponent (d^d) and then adding we have 16780890↔421845123:
1^1+6^6+7^7+8^8+0^0+8^8+9^9+0^0=421845123
and
4^4+2^2+1^1+8^8+4^4+5^5+1^1+2^2+3^3+=16780890.
