Alone at the Typewriter, With an Unusual Use of Mozart

Image source: here.

At 53, I’m old enough to have needed a typewriter to write papers, as an undergraduate, back when I was still living with my mother in Little Rock, Arkansas (USA), and attending the University of Arkansas at Little Rock, or UALR. Majoring in history, I wrote many. When I did this, I had a certain ritual about the activity, one that fell from use once I made the much-appreciated transition to using computers, instead.

First, I had to have the typewriter in the center of the living room, oriented at a 45 degree diagonal to the walls. Next, I had to be wearing a bedsheet, wrapped around one shoulder, toga-style. No other clothes were permitted. Finally, I had to have my vinyl version of Mozart’s Requiem playing, over and over, from the time I started the paper until it was completed. This would generally happen early in the morning, on the day the paper was due, procrastination being one of my defining characteristics at that age.

I’m glad I don’t have to write papers anymore, and that the typewriter era is over.

Two Polyhedra Derived From the Icosahedron

The polyhedron above is a zonish icosahedron, with zones added to that Platonic solid based on its faces and vertices. Its faces are twenty equilateral triangles, thirty equilateral decagons, and sixty rhombi. After making it, I used faceting to truncate the vertices where sets of five rhombi met, creating the polyhedron below. It has twelve regular pentagons as faces, with the sixty rhombi of the polyhedron above turned into sixty isosceles triangles, along with the thirty decagons and twenty triangles from the first of these two polyhedra. This second one could be called either a faceted zonish icosahedron, or a truncated zonish icosahedron.

Both of these polyhedra were created using Stella 4d: Polyhedron Navigator, software you can try for free at http://www.software3d.com/Stella.php.
