Abstract | This expository
article explains how planar diagrammatics naturally arise in the
study of categorified quantum groups with a focus on the categorification of quantum $\mathfrak{sl}_2$. We derive the definition
of categorified quantum $\mathfrak{sl}_2$ and highlight some of the
new structure that arises in categorified quantum groups. The expert
will find a discussion of rescaling isomorphisms for categorified
quantum $\mathfrak{sl}_2$, a proof that cyclotomic quotients of the
nilHecke algebra are isomorphic to matrix rings over the cohomology
ring of Grassmannians, and an interpretation of `fake bubbles' using
symmetric functions.
