# Amherst College Math Colloquium

The Amherst College Math Colloquium is a series of talks for undergraduates.

All are welcome! The talks are intended to be mostly accessible to students who have taken calculus, although they may also provide a preview of deeper waters. The colloquium talks are usually one hour long (50 + 10 minutes for questions). We usually have a 30 minute pre-talk small gathering (with snacks and refreshments) beforehand.

The 2023-2024 colloquium is organized by Ivan Contreras and Nathan Pflueger.
