Professor Elizabeth Drellich from Swarthmore College will present "Cars, Cartoon,s and Cohomology". Free pizza and everyone welcome to attend.
How do you program a 3D printer to get the sleek curves on your model of your favorite car? How do animators make sure that complicated surfaces appear smooth on screen? And what do these questions have to do with algebra? The surface of your model car or your favorite Pixar character's face is made up of a collection of polynomials that fit together smoothly called a spline. These splines are models, but they are also algebraic objects that can be added and multiplied. Some splines even contain deep information about the structure of groups and algebraic varieties, but you don't need to know what those are for this talk. This talk will introduce you to splines and show you some of their many wonderful uses.
