Steve Schluchter's Article on Tactile Graphs for a Blind Student

Steve Schluchter  recently published an article on his experience teaching a blind student at George Mason, including the tactile graphs previously described in this blog:  http://gmumathmaker.blogspot.com/2015/11/tactile-graphs-for-blind-math-student.html

A Visit to Lanier Middle School

Patrick Bishop teaches students to design fractals

GMU Math Makerlab graduate student Patrick Bishop and professor Evelyn Sander had a great time showing Lanier Middle School students how to create mathematical objects in OpenSCAD. We witnessed some rebellion done right when students went off script to create their own objects. While it was the last week of school, but they still showed incredible enthusiasm for 3D printing and design!  Thanks to Lanier and in particular Matt Bechtel and Rob Hornfeck for inviting us into the classroom!

Mathematics in Motion at the Maker Faire NOVA

Department of Mathematical Sciences students Patrick Bishop, Alathea Jensen, Jack Love, and Arsah Rahman and Professor Evelyn Sander ran the booth Mathematics in Motion featuring their original mathematical artworks  at the Maker Faire NOVA on March 18, 2018. A great success!

Dual Solids: The Cube and The Octahedron

by Patrick Bishop, Arsah Rahman, and Dr. Evelyn Sander


Two polyhedra are dual to one another if the verticies of one correspond to the faces of the other. Here we demonstrate the progression of a cube becoming an octahedron.

These prints were designed in OpenSCAD. The base is designed to fit the shape. It is slanted at the front for maximum viewing of the shape.

There are two other pairs of regular solids, the icosahedron/dodecahedron, and the tetrahedron and itself.

Construct3D

Had a great time at the Construct3D conference at Duke University May 5-7, 2017. I gave a talk on printing chaotic dynamical systems. Here is a copy of the talk and of the three codes that I talked about. If you use them, send me an email and let me know how it goes!
