On this page will be pictures of sculptures I made in Spring and Summer 2019. Below are pictures of a (3,5) torus knot made of black palm wood, completed on Feb. 3, 2019. It is about 3.75" in diameter and 1.5" high.

Here is a picture of my mathematical jewelry design ``Python 3-5 Torus Knot Pendant" 3D printed by Shapeways out of a new material, Dark Grey PA12 Glass Beads, received on April 30, 2019. This material is described by Shapeways as being a multijet fusion plastic made of 40% glass bead filled nylon 12 plastic with high stiffness and dimensional stability. The surface has an interesting texture.

I have received some wood for carving, Sirari Rosewood, Amazakoue, Black Mesquite and Figured Walnut, which I will make into six sculptures this summer, each a 3-5 torus knot. As of April 30, 2019, they have had the central core drilled out, the corners cut off to make each a cylinder, and those have been further rounded to a torus (doughnut) shape. I have marked on each one the 3-5 torus knot, but I have not yet started carving out the rough valley which emphasizes the knot. I will post pictures when they are ready to be seen. On the weekend of October 12-13, 2019, there will be a sectional meeting of the American Mathematical Society at Binghamton University, hosted by our Department of Mathematical Sciences. I am serving as the overall local organizer, and also co-organizing a special session in my area of expertise. There will be a book sale of AMS books, as usual, but I will also exhibit (and sell) some of my sculptures.

On August 7, 2019, I completed two of the 3-5 torus knot carvings mentioned above, one is Figured Walnut, about 1.75" thick and 5.5" in diameter, shown in the next three pictures. The other one is made of Sirari Rosewood, and is about 1.25" thick and 5.5" in diameter, shown in the last three pictures. These pictures show both sides and a view from an angle. I may not get to complete all six of the torus knot carvings as planned this summer, but I will do so eventually. I also bought some other wood samples in sizes which will be appropriate for carving Borromean rings or other shapes. I hope the book I recently bought, ``Woodcarving Magic" by Bjarne Jespersen will teach me how to carve some interesting new math shapes.
