Some pavers spotted in Cairo last month

A Truchet cafe, in Cairo last month

5-stars were commonly used on the ceilings of tombs and other buildings in Ancient Egypt to depict the heavens. They are usually not connected to one another, but they are connected in this ceiling in the Ptolemaic Denderah Temple to form a sort of tessellation of hexagons and quadrilaterals.

Ancient Egyptian numbers used to track sacrifices on the side of the Temple of Ramesses III (1217 BC - 1155 BC) in Luxor. A vertical tick mark denotes 1 and an inverted U ten.

Everyone is invited to attend the SCULPT 2025: Show & Tell, a digital gathering that celebrates creative exploration across art, geometry, design, and fabrication. Date: Friday, November 7, 2025 Time: 8:00 – 10:30 AM (PST) Zoom Link: cca.zoom.us/j/9826107944...

Polyaboloes, polygons formed by joining isosceles right triangles in edge-to-edge fashion, can also be arranged iteratively to form fractal self-replicating tiles. A particular tetrabolo was used to form these two reptiles, with mirroring between successive iterations employed in the right one.

Two fractal self-replicating tiles formed by iterating a 4-rhomb. On the right with mirroring between successive iterations.

This weekend would be a great time to submit your art for the exhibition to be held at the Joint Mathematics Meetings. Take advantage of this opportunity to share your work with over 5000 attendees this January in Washington, DC. You’ll need to submit by the 15th at gallery.bridgesmathart.org.

Polyrhombs, formed by joining 60°-120° rhombi in edge-to-edge fashion, can also be iterated to form self-replicating tiles. A 3-rhomb iterates to the same fractal as the envelope of the terdragon curve. Mirroring between successive iterations yields a very different looking reptile (right).

I just finished a new website on fractal self-replicating tiles ("reptiles") based on polyominoes, polyhexes, and polyiamonds: www.mathartfun.com/fractaldiver...

New sculpture illustrating the fact that cutting a three-half-twists band lengthwise results in a trefoil knot. Unglazed ceramic and leather cord.

Submissions are now being accepted for the Exhibition of Mathematical Art to be held as part of the Joint Mathematics Meetings, Washington, DC, in January of 2026. Apply online through October 15 at gallery.bridgesmathart.org. pic.x.com/MGSEyexSzo

A new article is out of which I'm a coauthor: "Visualization of Escher-like hyperbolic tessellations": www.sciencedirect.com/science/arti...

Submissions are now being accepted through September 14 for SCULPT 2025. Accepted work will be presented in a ZOOM Show and Tell event on November 7. In addition, works will be digitally showcased in the exhibition section of SCULPT 2025 and in a proceedings volume.

This mixed-media piece consists of an unglazed black-clay ceramic band with two half twists, making it a two-sided object. Steel dowels with long and short ends are spaced along the centerline to define a second band with two half twists, orthogonal to the first.

New hand-built ceramic piece employing negative curvature

Hand-built ceramic sculpture from 2019

Hand-built ceramic piece from 2020. Three different unglazed types of clay.

Some photos from the exhibition that opened at the National Museum of Mathematics Thursday, on 5th Ave in NYC. The other artists/mathematicians in the exhibition were Nicolas Belmonte, Chaim Goodman-Strauss, Edmund Harriss, Stepan Paul, Henry Segerman, and Steve Trettel.

I'll be in NYC this week for the opening of an art exhibition at the Museum of Mathematics. "Warped Realities" showcases the work of seven artists, and includes ten of my ceramic sculptures. If you're able, please join us Thursday evening at 6:30. . momath.org/composite-ga...
