A Tetrahedral Exploration of the Icosahedron

Posted on 24 June 2016 by

Mathematicians have discovered more than one set of rules for polyhedral stellation. The software I use for rapidly manipulating polyhedra (Stella 4d, available here, including as a free trial download) lets the user choose between different sets of stellation criteria, … Continue reading →

An Asymmetrical Static Equilibrium Physics Problem Involving Pulleys and Hanging Masses

Posted on 16 April 2016 by

An interesting phenomenon in physics, and physics education, is the simplicity of symmetric situations, compared to the complexity of similar situations which are, instead, asymmetrical. Students generally learn the symmetrical versions first, such as this static equilibrium problem, with the … Continue reading →
