Topologyâ€”the mathematical study of shapes that describes how a donut differs from a donut holeâ€”has turned out to be remarkably relevant to understanding our physical world. For decades, itâ€™s captured the hearts and minds of physicists, who have spent that time uncovering just how deep the connection between topology and physics runs. Among many other things, theyâ€™ve unearthed a prediction, born of topology, for a new particle with promising applications to quantum computing.

In this episode of the Joint Quantum Institute's *Relatively Certain *podcast, Dina Genkina sits down with Associate Professor Jay Sau and Professor Johnpierre Paglione, the director of the Quantum Materials Center. They take a trip back to the 1980s, when the story of topology in physics began, and arrive at a recent discovery by Paglione and his collaborators of a (possible) topological superconductor.

This episode of *Relatively Certain* was produced by Dina Genkina, Chris Cesare, and Emily Edwards. It features music by Dave Depper, Frequency Decree, Chad Crouch and Scott Holmes.
