#Mathologer : « #Lill's method, an unexpectedly simple and highly visual way of finding solutions of #polynomial #equations (using #turtles and #lasers). After introducing the method I focus on a couple of stunning applications: pretty ways to solve quadratic equations with ruler and compass and cubic equations with #origami, #Horner's form, #SyntheticDivision and a newly discovered incarnation of #Pascal's famous triangle. »
