| bgcolor="#BCD2EE" |Watch Caroline eat a donut: an introduction to Morse theory
| bgcolor="#BCD2EE" |Morse theory has been described as "one of the deepest applications of differential geometry to topology." However, the concepts involved in Morse theory are so simple that you can learn them just by watching me eat a donut (and subsequently watching me give a 20 minute talk explaining Morse theory.) No background is needed beyond calc 3 and a passing familiarity with donuts.

| bgcolor="#BCD2EE" |The Fold and Cut Theorem
| bgcolor="#BCD2EE" |The fold and cut theorem states that any shape consisting of straight sides can be cut from a piece of paper with a single cut by flat folding the paper. Come prepared to do a lot of folding and not a lot of cutting.

Very approachable if you know what a group is but does require tons of ping pong experience.

The AMS Student Chapter Seminar (aka Donut Seminar) is an informal, graduate student seminar on a wide range of mathematical topics. The goal of the seminar is to promote community building and give graduate students an opportunity to communicate fun, accessible math to their peers in a stress-free (but not sugar-free) environment. Pastries (usually donuts) will be provided.

  • When: Thursdays 4:00-4:30pm
  • Where: Van Vleck, 9th floor lounge (unless otherwise announced)
  • Organizers: Ivan Aidun, Alex Bonat, Kaiyi Huang, Ethan Schondorf

Everyone is welcome to give a talk. To sign up, please contact one of the organizers with a title and abstract. Talks are 25 minutes long and should avoid assuming significant mathematical background beyond first-year graduate courses.

The schedule of talks from past semesters can be found here.
