    In Conversation with Professor Philip Stamp: Superfluid Helium and Quantum Vacuum Tunnelling

    Professor Philip Stamp is Professor of Theoretical Physics at the University of British Columbia and Director of the Pacific Institute of Theoretical Physics, known as PITP, which he returned to Canada to establish in 2002. Mostly raised in New Zealand and educated in the United Kingdom, Professor Stamp began his academic life in philosophy and literature before turning to theoretical physics. He has since worked as a physicist in France, Spain, New Zealand, the Netherlands, Japan, Canada, and the United States. His research explores many aspects of quantum mechanics, including macroscopic quantum phenomena, quantum tunnelling, quantum gravity, and quantum cosmology. In this episode, we speak about his recent work with collaborators on superfluid helium and quantum vacuum tunnelling. The research uses an ultra-thin film of superfluid helium to examine the Schwinger effect, a famous prediction in quantum electrodynamics in which, under extreme conditions, the quantum vacuum may produce particle–antiparticle pairs. In Professor Stamp’s work, this idea is approached through vortex and anti-vortex pairs emerging in a quantum liquid. Our conversation turns to the meaning of the quantum vacuum, the difficulty of observing the Schwinger effect directly, the relationship between theory and experiment in physics, and finally, the strange beauty of a universe that is, in Professor Stamp’s words, both magical and real.

    When Bells Spoke: A Conversation with Musicologist Dr. Alex Fisher

    The Blue Hour: Sackbuts, Soundscapes, Bells, and Reformation Germany My interview with Professor Alex Fisher is now available as a podcast. In this conversation, I speak with Professor Fisher about bells, early music, soundscapes, weather, ritual, and the religious worlds of sixteenth- and seventeenth-century Germany. Alex Fisher is Professor in the UBC School of Music, where he coordinates Early Music. He is both a distinguished musicologist and a performing musician. Trained as a trombonist, he later specialized in the Renaissance sackbut and has performed with leading early music ensembles. He is also a co-founder of Cappella Borealis. As a scholar, Professor Fisher studies the musical, religious, and cultural worlds of early modern Germany, with particular interests in soundscapes, ritual, and the relationship between music and religious identity during the Reformation and Counter-Reformation. His work has appeared in leading journals, including the Journal of Musicology, Early Music History, and the Sixteenth Century Journal. His books include Music and Religious Identity in Counter-Reformation Augsburg and Music, Piety, and Propaganda: The Soundscapes of Counter-Reformation Bavaria. We focus especially on two of his more recent publications: his chapter “Bells” in Information: A Historical Companion, published by Princeton University Press in 2021, and his article “Hearing the Trumpets of the Church Militant: Weather Bells and Supernatural Audition in Post-Reformation Germany,” published in the Sixteenth Century Journal in 2022. Together, they invite us to think about bells not simply as musical instruments, but as technologies of communication, symbols of civic and religious life, and, for many centuries, voices believed to reach both human and supernatural listeners.
