David Politzer, “The Physics of Banjos” (Open Agenda, 2021)

The Physics of Banjos is based on an in-depth filmed conversation between Howard Burton and David Politzer, 2004 Nobel Laureate and the Richard Chace Tolman Professor of Theoretical Physics at Caltech. This extensive conversation examines many of the intriguing aspects associated with the physics of banjos, including the ocarina effect, string-stretching, the subtleties of how we hear pitch, transient growth, and the mysterious ringing sound of banjos; while also touching briefly on contemporary issues in black holes and particle physics.
