Martin Gardner was fascinated by tessellations, as am I. This year I have decided to share a 3D printed model of a fun math tile that we have been using in our Math Carnivals in the Republic of Panama, organized by the Panamanian Foundation for the…
A very small infinity cube with acrylic 2-way mirrors on the inside, with a hole for inserting a light source. Comes as a kit: 6 laser cut squares with finger joints and a small keychain light.
This is a physical item, but the item is a piece of paper. My Celtic knot generator will create 200 unique randomly generated knots, that all spell out Martin Gardner's name. I will provide a printout of the rendered knot and the instructions on how…
The physical gift bag Zone Proxima Math flier title: Zone Proxima presents Early Childhood Math: Ages 4.5 - 6.5
In the spirit of G4G, Zone Proxima offers the opportunity for adults (parents, caregivers, educators, and philanthropists) to improve…
It is a long G4G tradition that for G4GX that there are two speakers, one of which extols the number X and one which cast aspersions on X. This the latter effort.
Elevating tessellations to act as nets for geodesic domes have many applications in structural engineering, math, and synthetic biology. In this paper I describe a net and a 3D version of a heptagon-containing polyhedra, as well as sphericity…
The French name for the Fifteen Puzzle is "Jeu de Taquin". The generalization by Schützenberger to Young tableaux has many amazing properties, and important applications in combinatorics, representation theory and algebraic geometry.
For it's decade of existence the Circo Matemático (mathematical circus), a autonome group of popularisers of mathematics part of the Ludus Association, designed a deck of cards.
The poker-sized cards (63x88 mm) are COPAG 310 quality, slimline, with…
This is a 3D printed space filling curve cased on the Gosper curve. It is surprisingly flexible and invertible. I originally printed it for a tactile experience with a space filling curve, but my colleagues loved it so much I thought it would be a…
My gift has four cardstock patterns for you to assemble at home: band trefoil, stella octangula, excavated dodecahedron and the fourteenth stellation of icosahedron. I'll bring a printout or cutout copy of the first three projects as well.
Martin Gardner wrote changed the lives of thousands of people with his writings. But even he felt powerless to bring joyful mathematics into classrooms. In this article, I discuss the barriers to the widespread adoption of recreational mathematics…
