After talking with Minnesota Landscape Arboretum, we began searching for new ideas to interact with Voronoi Diagrams. During our pre-pandemic presentations and events we allowed people to interact with a Voronoi simulation that had been posted on Wikipedia. https://en.wikipedia.org/wiki/File:Voronoi_growth_euclidean.gif While brainstorming we decided to buy a flipbook kit and test out what we could do with them. One of our

We were inspired by a post on Twitter by Olivier Longuet shown below. The object in the photo is an icosahedron, a 20-sided 3D shape, made out of three golden rectangles with side lengths that obey the golden ratio (1:1.618033…). To make a cardboard version of the icosahedron, print out this document and follow the instructions! You can also make

This is a great example where mathematicians applied some creative thinking to solve a very real world problem.  It is Abraham Wald’s Survivorship Bias problem.  To help explain the sequence of concepts that lead to his insight, we made some wooden planes to help visualize the problem, and the solution. We start out thinking about the planes that come back

You don’t need robots and computers, just a system and apparatus to organize the steps! This model is based on the results alluded too but not completely explained by an Israeli company in the recent NY Times article by David Halbfinger on creative pool testing options.   https://www.nytimes.com/2020/08/21/health/fast-coronavirus-testing-israel.html Trying to come up with one of these is a great activity for
