Hi, I’m David Plaxco. On this account, I share aesthetic solution states of n-layer Rubik's cubes. Otherwise, I teach math at UGA, research undergraduate mathematics education, and try to make my experiences here on earth more meaningful.

Godspeed. Having to try a couple out seems to be a really typical part of the process. Also, nothing is a silver bullet. I still have bad days on the meds and good days off them.

Here’s a knot on the 9-cube that my colleague @cubicskies.bsky.social and I call the great-great-granny knot. It’s the connected sum on four trefoil knots.

I’m not following your logic here. This doesn’t exclude lasagna from sandwiches so much as it introduces the club lasagna.

You mean a dystopian wasteland piled with garbage from which humans escape via a monopolistic company’s life raft spaceship that doesn’t actually have a feasible plan, but instead turns out to be a conspiracy to pacify people until they stop asking questions? I think they are building that.

MoMath will host a free online event on Friday, Aug 28 at 12:00pm US Eastern time premiering a new video by Sabetta Matsumoto, Tim Reinhardt, Jürgen Richter-Gebert, and me, on hyperboloids made out of sticks and how they move. Details and registration at momath.org/hyperboloids/
A hyperboloid of one sheet made out of wooden skewers next to Mae West, an enormous sculpture of a hyperboloid of one sheet in Munich. Next to the wooden skewers hyperboloid is written “This one doesn’t exist”.

This is the FTO (face-turning octahedron) twisty puzzle. It’s now an official WCA event And I think it’s lovely. Here, I’ve solved it to a pattern that is striped when viewed from 4 vertices, and concentric squares from 2 vertices.
I imagine other folks have done this pattern, but I just had to try it. I don't know what to call it... Stripes? I don't think it's octahedron-in-an-octahedron. One thing I really like about this pattern is that (I think) there's a sort of parity to the colors. l've learned that this puzzle has two classes of colors - blue/red/ purple/yellow and white/gray/orange/green. If you notice here, the blue & red pieces are swapped and so are the yellow and purple pieces (as a permutation, this is two disjoint 2-cycles).
These colors form a tetrahedron on the octahedron (no two are adjacent). There is a dual tetrahedron formed by the other four colors! But those colors are not swapped in pairs; the three white triangles moved to the gray face, the gray triangles to the orange face, the orange triangles to the green face, and the green triangles to the white face (as a permutation, this a 4-cycle!).

I cut flowers from my garden today and put them in three Growth Vases. We created them in 2009, using a branching growth algorithm to generate the form. 17 years later, I’m still fascinated by the same question: what can we make when we use nature’s algorithms for growth to create art and design?

Excited to have my art Topological Trio included in the Bridges 2026 Exhibition of Mathematical Art, Craft, and Design, held this week in Galway, Ireland. My related paper is also part of the program. #MathArt #LEGO
These three LEGO designs celebrate several topological structures. A model of Borromean rings is constructed in red, green, and blue; the brick dimensions offer just enough tolerance to feel the rings are separate. An orderly tangle of six squares is constructed from six layered squares made of white and tan plates. A double layered cube based on a design by Rinus Roelofs is constructed from three layers of plates.
