What makes mathematics beautiful? The National Museum of Mathematics asks that question to a number of famous mathematicians and records their answers in this delightful series. Bryna Kra, professor of mathematics at Northwestern University, speaks of the beauty she sees in discovering and understanding patterns between two mathematical problems that, at first glance, appear to be unrelated. Kra then goes on to discuss the role of Schur's theorem in combinatorics. In another video, Manjul Bhargava talks about the uses of pi outside of geometry and discusses the beauty in the unity of mathematics: subfields that appear disconnected are, in fact, intertwined. These short videos will appeal to math scholars as well as those more casually interested in math, and offer an enjoyable way for anyone, regardless of their previous mathematics education, to learn something new.
