Pi in the Sky

Pi in the Sky offers short crafted journeys into cosmology, astrophysics, and fundamental physics for curious non-experts.

Created by Matt McQuinn, theoretical cosmologist and professor at the University of Washington, each episode explores a single topic he finds fascinating — what it is, why it matters, and how scientists figured it out, with a light touch.  No prior background is assumed.

Matt has coauthored nearly one hundred peer-reviewed research papers, and his work has been recognized with a Sloan Fellowship in Physics, a visiting professorship at the Institute for Advanced Study, first-place Buchalter Cosmology Prizes in 2023 and 2025, and NASA research fellowships (Hubble, Einstein, NIAC).
