Marisa Walbert 20 Episodes Apr 15, 2026

Radio Physics makes physics accessible to everyone, no scientific background required. The show is a collaboration between top high school physics students from Aspen to Rifle, the Aspen Center for Physics, and KDNK Community Radio in Carbondale. Students interview some of the more than 1,000 physicists who visit the Aspen Center for Physics each year, exploring fascinating questions and answers about the universe.

Episodes

Radio Physics | Csaba Csáki
Radio Physics | Csaba Csáki Apr 15, 2026 1651 On this episode of Radio Physics, Sasha Fielder sits down with renowned theoretical physicist Csaba Csáki to explore the frontiers of modern particle physics.From the high-energy collisions at the Large Hadron Collider to the silent mystery of the cosmos, this interview breaks down the complex "math of the universe" into a conversation for the curious mind. Listen to Radio Physics on KDNK.org ever
Radio Physics | Krishna Rajagopal
Radio Physics | Krishna Rajagopal Mar 31, 2026 1779 This time on Radio Physics, intern Henry Billinghurst talks with theoretical physicist Krishna Rajagopal, exploring one of the most extreme states of matter in the universe: “hot quark soup,” or quark–gluon plasma and how scientists recreate this early-universe matter using powerful particle colliders to briefly produce tiny droplets of this ultra-hot, liquid-like plasma. They discuss the physics
Radio Physics | Ryan Foley
Radio Physics | Ryan Foley Feb 18, 2026 1650 In this episode of Radio Physics, hosts Jack Kravitz and Sasha Fielder sit down with physicist Ryan Foley. The episode dives into gravitational waves, the dramatic collisions of neutron stars and the black holes they can create and how neutron star mergers help scientists measure the expansion rate of the universe, offering new clues about the cosmos’s past and its ultimate fate. Listen to Radio P
Radio Physics | Astrophysicist Cole Miller
Radio Physics | Astrophysicist Cole Miller Jan 21, 2026 1740 On this episode of Radio Physics, astrophysicist Cole Miller, joined by intern Sasha Fielder, discuss black holes—from the formation of early, very massive black holes to black holes orbiting black holes and the gravitational waves they produce, as well as multi-messenger astronomy, neutron stars, tidal forces, and discoveries from LIGO and VIRGO, along with insights gained from working with NASA’
Radio Physics | Ned Wingreen
Radio Physics | Ned Wingreen Dec 17, 2025 1650 On this episode of Radio Physics, summer intern Alice Lebedev-Migdal interviews physicist Ned Wingreen. Ned's current research focuses on modeling of bacteria, bacterial communities, phages, and other microorganisms, as well as studies of intracellular phase separation, and topics in immunology. Listen to Radio Physics on KDNK.org every third Wednesday at 4:30pm.
Radio Physics | Flip Tanedo
Radio Physics | Flip Tanedo Nov 19, 2025 1413 On this episode of Radio Physics, physicist Flip Tanedo is interviewed by interns Shen Harman & Alice Lebedev-Migdal. Flip Tanedo builds models of dark matter. He is spending his time at Aspen Center for Physics thinking about ways in which dark matter can explain the mysteriously gigantic black holes that have been puzzling astronomers for the past 10 years and is also writing a textbook on linea
