Whimsical Wavelengths - A Science Podcast
Hosted by Volcanologist & Geophysicist: Jeffrey Mark Zurek, PhD, PGeo | Science Communicator · EN
Winner of the 2026 Science Podcast of the Year (American Writing Awards) and the 2026 PopCon Podcast Award for Science and Technology, Whimsical Wavelengths is a science podcast hosted by volcanologist Dr. Jeffrey Zurek dedicated to the "how" and "why" of discovery.
Eschewing the trend of bite-sized science, the show offers a deep, honest look at how science actually works, focusing on messy data, imperfect models, and the human personalities behind the research. From geophysics and planetary discovery to the history of scientific paradoxes, the focus is always on the process: how evidence is gathered, how ideas evolve over centuries, and why uncertainty is a fundamental feature of science rather than a flaw.
Because science is conducted by people, Whimsical Wavelengths does not ignore the human element. I weave together mathematical rigor and historical context with reflections on the realities of building a scientific career and what it truly means to belong in STEM. Whether it is a solo narrative exploration or a conversation with a working researcher, the goal is clarity without oversimplification.
The tone is thoughtful and curious, anchored by real-world field experience and the occasional groan-worthy dad joke, because while the science is serious, the pursuit of it is a human adventure. This is for listeners who want to understand the machinery of the natural world and the people who spend their lives trying to take it apart.

Bottoms Up: Decoding Kilauea’s Deep Magma Supply
2w ago00:56:04Tap to summarizeKilauea is one of the world's most studied volcanoes, but its deep plumbing still holds mysteries. In this episode, we dive into a "bottoms-up" view of Hawaii’s magmatic system with Gaetano Ferrante, exploring how pressure changes in the deep mantle conduit propagate to the surface.While volcanologists often focus on shallow, top-down triggers like summit collapses or CO2 degassing, Gaetano’s recent research suggests that the deep mantle pathway—stretching nearly 100 km down—plays a much more active role in regulating magma supply than previously thought. We break down the mechanics of mantle plumes, the transition from magmastatic to lithostatic pressure, and why the "elastic" response of volcanic pipes might explain Kilauea’s stable behavior following the massive 2018 eruption.Inside the EpisodeThe Bottom-Up Model: Why the deep magmatic system can drive surface activity independently of shallow reservoir changes.Mantle Plume Dynamics: How hot mantle rock rises and undergoes decompression melting to fuel the Hawaiian hotspot.The CO2 Proxy: Understanding why carbon dioxide is our best "telescope" for looking 35 km beneath the island.Conduit Elasticity: How deep magma pathways deform to accommodate surges in supply rate, like the stable surge observed between 2003 and 2007.Geoid Humor: A classic geodynamics joke to wrap up the season’s deep dives.Show Timeline(00:00) Hawaii: Volcanoes, Frogs, and Microclimates(02:25) Top-Down vs Bottom-Up Eruption Dynamics(04:20) Introducing PhD Candidate Gaetano Ferrante(06:40) From Italy’s Vesuvius to Hawaii’s Hotspots(09:40) Is Kilauea a Normal Volcano?(13:30) Plumbing the 100km Deep Magma Pathway(15:10) Mapping the Summit Magma Reservoirs(19:00) Lessons from Top-Down Rift Processes(23:00) CO2 and Deep Volatile Solubilities(26:30) Magmastatic vs Lithostatic Pressure(33:45) The 2003-2007 Surge and Conduit Elasticity(40:45) Steady States and 2018 Eruption Feedback(45:50) Viscoelastic Futures and Heat Transfer(52:40) Perpendicular to the Geoid: A Science JokeLinksPapers: Bottoms up: Coupling versus decoupling within Kı̄lauea’s magma supply systemWeb: WhimsicalWavelengths.comSupport: PateronSocials: Bluesky | Instagram | FacebookWhimsical Wavelengths: Deep-dive conversations where a working scientist unpacks how we know what we know, one paper, one idea, or whimsical detour at a time.

Of Cows and Cures: Reconstructing the Logic of Vaccination
4w ago01:05:29Tap to summarizeWe treat modern medicine as a given, but for centuries, humanity was blind to the invisible agents of disease. In this solo episode, Dr. Jeff Zurek takes off his volcanologist hat to tackle a listener request.We start with the 14th-century Black Death, tracing how we moved from medieval superstition to engineering viral defenses. We break down the "Sausage-Making" of science, including how 19th-century lens technology and staining finally allowed us to see the microbes that had been killing us for millennia.We also settle the Germ vs. Terrain debate. While the "wellness economy" resurrects 150-year-old ideas about "optimizing terrain," the data shows the microbe is the match that starts the fire. From Pasteur’s gamble with a rabid nine-year-old to the modern mRNA revolution, we explore how evidence survived contact with reality.Topics CoveredMedieval Logic: Divine punishment, miasma, & astrology.Yersinia Pestis: The "Hyperparasite" that broke serfdom.Variolation to Vaccination: The gross, effective history of cowpox.Germ vs. Terrain: Why "M-A-H-A" uses outdated 1850s logic.Pasteur’s Engineering: Outrunning rabies in 1885.Modern Milestones: Polio, MMR, & mRNA.Chapters(00:00) Intro: The 50% Mortality Rate(01:50) The "Sausage-Making" of Science(03:15) MD vs. Geophysicist: A Disclaimer(05:00) Medieval Responses to the Plague(07:25) Miasma: Correlation vs. Causation(09:00) The Biology of Yersinia pestis(11:30) Why Stable Hands Survived(14:15) Quarantina: The Biblical 40 Days(17:00) The Microscope Resolution Barrier(21:45) Debunking Spontaneous Generation(24:00) Variolation: The Scab Gamble(27:15) Cowpox: The Latin Root of Vaccines(32:25) The Debate: Germs vs. Terrain(35:45) MAHA and 19th-Century Clichés(37:30) Why Germ Theory Won(40:40) Engineering the Rabies Vaccine(45:20) Timeline: From Antitoxins to Polio(48:30) Conjugate Vaccines & Sugar Coats(51:00) The Logic of Vaccine Schedules(53:40) Goop and the Wellness Economy(56:30) Pathogens as Terrain Modifiers(01:01:00) Conclusion: A Microbial StoryLinks & ResourcesSupport: PateronSocials: Bluesky | Instagram | FacebookWhimsical Wavelengths: Deep-dive conversations where a working scientist unpacks how we know what we know, one paper, one idea, or whimsical detour at a time.

Inclusive Fieldwork: How Accessibility is Changing the Future of Geosciences
Apr 2700:57:14Tap to summarizeFor decades, the "field" has been treated as a character-building barrier in geosciences—a place for the rugged and the able-bodied. But what happens when we view the outdoors as a classroom rather than an obstacle? In S2EP16, Jeff Zurek welcomes Brett Gilley, a Professor of Teaching at the University of British Columbia (UBC) and a master of field pedagogy.They dive into the results of a groundbreaking accessible field trip held right here in Vancouver. From the shores of Stanley Park to the volcanic peaks of Whistler, we discuss Universal Design for Learning (UDL) and the "Mammoth Cave" inspiration. You'll hear the transformative story of a visually impaired student who traded her seeing-eye dog for a rock scramble and a professor with a progressive disability who finally got off the bus to argue geology again.Whether it's using Silly Putty to feel 3D models or running "Mission Control" from a dorm room, this episode proves that diversity is the lifeblood of discovery.
