I’ve recently been on an origami craze. Even though origami is an ancient Japanese art, a lot has been written about the mathematics of origami and paper folding (as a simple Google search will show). Origami, and paper folding in general, has many interesting algebraic, and of course, geometric properties. The mathematics in many of the articles I’ve seen is pretty complicated and I won’t even try to pretend that I fully understand it. One of the AMS Notices from last year had an article that “use[d] origami as a tool to exhibit explicit solutions to some systems of partial differential equations”. If you are at all interested, you can find the article here.

As far as my interests in origami go, yeah there’s some pretty deep mathematics, but I think it’s a cool hobby to have and I can make some cool decorations for my desk.
