The Biggest Ideas in the Universe is a series of videos where I talk informally about some of the fundamental concepts that help us understand our natural world. Exceedingly casual, not overly polished, and meant for absolutely everybody.
This is the Q&A video for Idea #13, "Geometry and Topology." We use the excuse to dig into some details of embeddings, how to express the Riemann tensor, what maps are involved in specifying homotopy groups, plus a bit about topological defects.
