In our latest WIM Video, Michigan State University Assistant Professor of Mathematics Teena Gerhardt discusses the sizes of infinite sets.

The Girls’ Angle WIM Video series is the brainchild of Girls’ Angle director Elisenda Grigsby. WIM Videos are often shot on the spur of the moment and feature women in mathematics explaining some piece of math that excited them when they were students. We hope to create a large gallery that will showcase the diverse group of women working in mathematics today.
