The * What is ...?* seminar will run again in Summer 2018. Professors Vitaly Bergelson and Daniel Shapiro serve as coordinators/mediators.

The seminar's main goal is to expose culturally ambitious participants to some mathematical notions not taught in standard courses. These topics form an important part of mathematical folklore, and may prove useful for doing research and enhancing teaching.

Lectures will be given mostly by graduate and undergraduate student participants.

## 2018 Talks

We will meet in Scott Lab N054 on Tuesdays and Thursdays at 4:00 during the Summer Semester.
