Summary

During Nobel Prize Week, Science Friday revisits a 2013 interview with Francis Halzen, who won the Physics Prize for his work on the IceCube Neutrino Observatory. Halzen explains how the detector, buried a mile deep in Antarctic ice, captures elusive high-energy neutrinos to study astrophysical phenomena and dark matter. The conversation highlights the unique properties of neutrinos, the challenges of building such a massive particle detector, and the playful tradition of naming detected particles after Sesame Street characters.
