Dodecafoam 2025
Dodecafoam is packing of space by a fractal froth of dodecahedra, scaled by powers of the golden ratio, related to the structure of novel “quasicrystalline” physical materials. For more than thirty years I’ve rendered this with compass and straightedge, photocopier, mathematical trading cards, cardstock blocks, and cheap and reproducible classroom activities. Finally, with a new generation of excellent home 3-D printers, we can touch the stuff.
Introducing Pomegranite from Another Planet— can you solve it and fit the pieces into their box?
Chaim Goodman-Strauss is an American mathematician recognized for his work in convex geometry and aperiodic tiling. He has held academic and research positions at institutions including the University of Arkansas, the National Autonomous University of Mexico, and Princeton University. He currently serves as the outreach mathematician for the National Museum of Mathematics.
Goodman-Strauss is a co-author of The Symmetries of Things, an in-depth exploration of the mathematical theory of patterns, celebrated for its innovative and visually striking illustrations. His contributions to recreational mathematics include “The Math Factor,” a podcast that popularized mathematical concepts, and active participation in events honoring Martin Gardner’s legacy.
Chaim was part of the team that resolved the “einstein problem” by proving the existence of an aperiodic monotile. This groundbreaking work continues to advance the field of mathematical tiling. Additionally, he is well known for his large-scale mathematical sculptures, which combine art and mathematical insight.
