This Spring term, I am lucky to be able to teach Knot Theory to a class of 18 students. This is an intensive 4 week term, where we meet for 2 and a half hours 4 days each week. We are using *An Interactive Introduction to Knot Theory* by Inga Johnson and Allison Henrich. One of the exercises in the first chapter asked us to look at a knot diagram and work out the connected sum components. One of my students made the knot out of pipe cleaners, then manipulated it to give the following solution. I liked this model so much I just had to stick it up on my office window.

Alongside learning basic Knot Theory, the students are learning how to 3D-print knots. This involves learning how to model the knots as a solid 3-dimensional object in Cinema 4D. Cinema 4D is a professional 3D modeling and animation program, and is similar in feel to Blender. We then print the knots on the 3D printers in W&L’s IQ center. We are mostly using the Ultimaker and Stratasys printers. The class will be writing posts for this blog on the knots they construct – so stay tuned for more.
