Ryan Patterson on the Physics of Neutrinos

December 8, 2025·1 hr 26 min·5 clips
Neutrinos only experience the weak force, passing through everything with 100,000 in your coffee cup at any moment.
Sean Carroll interviews Ryan Patterson, a particle physicist at Caltech, about neutrinos. They cover the history of neutrino discovery, their properties like weak force interaction and oscillations, and modern experiments like DUNE aiming to study CP violation and mass ordering. The discussion ties neutrinos to bigger questions like dark matter and matter-antimatter asymmetry.

As heard by us

A neutrino conversation that links standard-model gaps to the mechanics of making and tracking a beam.

Sean Carroll frames the conversation around neutrinos as a useful way to test where the standard model still falls short, while also showing how real experiments are designed and read.
