“Breaking Up Is Hard To Do: The Art of Decomposition”

with Jordan Ellenberg

Wednesday, December 2 at 4:00 pm and 7:00 pm ET (New York)

Among the most fundamental tasks of mathematics (or science) is to classify in order to understand what kinds of things there are in the world.  A particularly satisfying form of classification is when we can show that every complicated thing is built out of a much smaller set of simpler things.  In chemistry, we get this satisfaction from the periodic table; in mathematics, we find it just about everywhere, from numbers to polynomials to curved surfaces.  Take a tour of some of these “periodic tables” of mathematics with mathematician Jordan Ellenberg and join us as together we explore the surprising relationships among them.

Special introduction by Alex Kontorovich, MoMath’s 2020-2021 Distinguished Visiting Professor for the Public Dissemination of Mathematics and Rutgers math professor.

This is a live-streamed event.  Occasional video recordings are made available for a fee at videos.momath.org.
