A Polyhedral Journey, Beginning with FaceBased Zonohedrification of an Icosahedron
To begin this, I took an icosahedron, and made a zonish polyhedron with it, with the new faces based on the zones of the existing faces. Here’s the result. Next, I started stellating the polyhedron above. At the sixth stellation, … Continue reading

A Zonish Icosahedron, and Some of Its “Relatives”
To begin this, I used Stella 4d (available here) to create a zonish polyhedron from the icosahedron, by adding zones along the x, y, and zaxes. The result has less symmetry than the original, but it is symmetry of a … Continue reading

Cuboctahedral Cluster of Rhombic Triacontahedra
Due to their high number of planes of symmetry, rhombic triacontahedra make excellent building blocks to build other polyhedra. To make this, I used a program called Stella 4d, which you can try right here.

Anticarbon14 and Oxygen18 Nuclei: What If They Collided? And Then, What About the ReverseReaction?
Were nuclei of anticarbon14 and oxygen18 to collide (and their opposite charges’ attractions would help with this), what would happen? Well, if you break it down into particles, the anticarbon14 nucleus is composed of six antiprotons and eight antineutrons, while … Continue reading

Top 100 Banned/Challenged Books: 20002009
The best ways to celebrate Banned Books Week (which is going on now) are to read/buy/give away banned books, and/or donate money to libraries which deliberately put banned books in the circulating collection, as all good libraries do. I’ve colorcoded … Continue reading
