About the 1,2,...,3:The 1,2,...,3 Seminar is an opportunity to see some interesting mathematics (that is not usually included in the curriculum) in a very casual setting. Talks are typically on Fridays starting at 12:03 p.m. and guaranteed to end by 12:34 p.m., in the Math Lounge or in Schaefer 165. We will sometimes have snacks but feel free to bring your lunch.
