The Quanta Podcast
Quanta Magazine
Exploring the distant universe, the insides of cells, the abstractions of math, the complexity of information itself, and much more, The Quanta Podcast is a tour of the frontier between the known and the unknown. In each episode, Quanta Magazine Editor-in-Chief Samir Patel speaks with the minds behind the award-winning publication to navigate through some of the most important and mind-expanding questions in science and math. Quanta specifically covers fundamental research — driven by curiosity, discovery and the overwhelming desire to know why and how. Join us every Tuesday for a stimulating conversation about the biggest ideas and the tiniest details.(If you've been a fan of the Quanta Science Podcast, it will continue here. You'll see those episodes marked as audio edition episodes every two weeks.)

The Fundamental Tension at the Heart of Math
Layla Sloman, journalist who covered formalizing mathematics and the Lean proof assistant, guides listeners through the clash between creativity and formal rigor. She explains why proof assistants matter now. She outlines Lean’s workings, the labor of building a formal library, and the risks of homogenizing mathematical practice.

Audio Edition: AI Comes Up With Bizarre Physics Experiments. But They Work.
Researchers let AI redesign precision interferometers and uncovered alien-looking optical layouts that nevertheless cut quantum noise. Graph-based algorithms reinvented long-known quantum experiments in unfamiliar ways. Machine-learning models also surfaced better dark-matter formulas and hidden symmetries from collider data, while humans still supervise and interpret the surprising outputs.

Why Do Humanoid Robots Still Struggle With the Small Stuff?
John Pavlus, a science writer who covers robotics and tech, explores why humanoid robots still stumble on everyday tasks. He discusses the importance of human-like form, contrasts practical designs with flashy demos, and highlights gaps in force sensing, physical intelligence, and training data. The conversation examines breakthroughs, realistic timelines, and where true dexterity might come from.

Uniting a Century of Digital and Analog Astronomy
Liz Kruesi, science writer who links historical astronomy with modern surveys, explores how century-old glass plate photos are being reunited with Rubin Observatory data. She discusses connecting vintage and digital records to extend time baselines. Conversations cover changing celestial objects, plate-making and archives, and the hands-on work of digitizing and mining these photographic collections.

Audio Edition: Researchers Uncover Hidden Ingredients Behind AI Creativity
They unpack why image generators seem creative even when trained to mimic data. Listeners hear how diffusion models denoise images and why locality and translational equivariance matter. An experiment called the ELS machine reproduces many outputs, linking algorithmic glitches to pattern-forming biology. The discussion notes limits and contrasts these findings with other AI systems.

Astrocytes Might Be in Charge of the Brain
Ingrid Wickelgren, science journalist who covered astrocytes’ surprising roles. She explores how astrocytes envelop synapses, show calcium waves, respond to norepinephrine, and can influence behaviors from sleepiness to ‘giving up.’ The conversation highlights imaging breakthroughs, causal experiments in animals, and implications for mood and brain-state control.

The Infinite Heist - Part 2
Jordana Cepelewicz, math editor and science journalist who traces the history of mathematical ideas, guides a deep dive into the Cantor–Dedekind story. Short scenes cover Cantor’s 1874 paper and controversies, Kronecker’s campaign, a researcher’s hunt for missing letters, the 1873 Dedekind proof discovery, and how myths about lone genius and credit shape math history.

Audio Edition: The Ecosystem Dynamics That Can Make or Break an Invasion
Researchers use microbes as fast, controllable ecosystems to test what makes communities vulnerable to invasions. They explore diversity, interaction strength, and surprising phase shifts that change stability. Experiments show fluctuating, species-rich microcosms can be far more invadable. Models recreate these patterns and raise questions about dynamics in longer-lived systems.

The Infinite Heist - Part 1
Jordana Cepelewicz, math editor at Quanta Magazine who unpacks math history, tells the tangled origin story of Georg Cantor and infinity. She traces Cantor’s proofs of different infinities, the rise of set theory as math’s common language, and the publication intrigues and tensions with contemporaries that reshaped foundations. Short, dramatic, and full of historical twists.

Decoding the Mysteries of Quantum Mechanics
Philip Ball, science writer and author of Beyond Weird, brings crisp reporting on the foundations of quantum theory. He dives into wave-particle puzzles, the measurement problem, competing interpretations like collapse and many-worlds. He also explores decoherence, Quantum Darwinism, and why a single classical reality emerges from quantum possibilities.
