Self-assembly is the process during which a collection of relatively simple components, starting in a disorganized state, autonomously combine into a more complex structure. During self-assembly, there is no external guidance or direction, and the self-assembling components experience only local interactions and typically obey a simple set of rules that govern how they combine. We…Continue Reading Using Computation to Self-Assemble Patterns

Ruled Hyperbolic Paraboloid
This sculpture by Shalese Fitzgerald demonstrates the “ruling” of the hyperbolic paraboloid by lines.

Kakeya Needle Problem
Given a needle (or stick), what is the smallest area shape that we need to rotate the needle 360 degrees? We will look at this problem from the perspective of several different shapes, we will start with a circle and slowly shave off parts of the shape to see that we can get smaller and…Continue Reading Kakeya Needle Problem
Projective Geometry of Elliptic and Quadratic Curves
Parabolas, circles, and hyperbolas may look vastly different on a graph, but there is a way to paint these pictures on a ball such that they all turn into circles? It turns out that all quadratic curves turn into circles, and we can see this by copying a graph onto a balloon. What happens to…Continue Reading Projective Geometry of Elliptic and Quadratic Curves
Experiencing Hyperbolic Geometry
Experience mind bending hyperbolic geometry through virtual reality and craft activities. Come prepared to test your limits on reality with Hyperbolica, a virtual reality puzzle adventure game that visualizes what hyperbolic space is and how it can be interacted with. Then we will create a fun model of the hyperbolic plane to remember your time…Continue Reading Experiencing Hyperbolic Geometry
Platonic Solids
Platonic Solids are 3D shapes that: have faces identical in shape and size have the same number of faces meeting at each vertex, and are convex. How many such solids do you think meet these criteria? Surprisingly, there are precisely 5 and you can easily make them at home. With a hands-on approach through construction…Continue Reading Platonic Solids
