  • The Math of Catastrophe

    14/10/2025 Duración: 27min

    Around 6,000 years ago, the Sahara was a lush grassland. Then, as if a switch flipped, it began to dry out, becoming the desert that we know today. Tipping points are moments in Earth’s history where gradual change suddenly becomes rapid and forms a new equilibrium. They’re one of the most alarming threats of our planet’s near future — and one of the most uncertain. When will a tipping point occur? Mathematicians are attempting to turn vague, apocalyptic visions into something that we can actually prepare for and deal with. On this week’s episode, host Samir Patel speaks with contributing writer Gregory Barber about what tipping points can — and cannot — tell us about the future of our planet. This topic was covered in a recent story for Quanta Magazine. Each week on The Quanta Podcast, Quanta Magazine editor in chief Samir Patel speaks with the people behind the award-winning publication to navigate through some of the most important and mind-expanding questions in science and math.

  • AI's Dark Side Is Only a Nudge Away

    23/09/2025 Duración: 24min

    In order to trust machines with important jobs, we need a high level of confidence that they share our values and goals. Recent work shows that this “alignment” can be brittle, superficial, even unstable. In one study, a few training adjustments led a popular chatbot to recommend murder. On this episode, contributing writer Stephen Ornes tells host Samir Patel about what this research reveals. Audio coda from The National Archives and Records Administration.

  • How We Came To Know Earth

    16/09/2025 Duración: 24min

    For most of us, the word “climate” immediately generates thoughts of melting ice, rising seas, wildfires and gathering storms. However, in the course of working to understand this pressing challenge, scientists have revealed so much more: A fundamental understanding of how Earth’s climate works. Quanta recently published a nine-story series that investigates this basic science. On this episode of The Quanta Podcast, senior editor Hannah Waters joins editor in chief Samir Patel to discuss how humans have come to understand our planet.

  • Earth's Core Appears To Be Leaking Up and Out of Earth's Surface

    02/09/2025 Duración: 27min

    In science textbooks, Earth looks like a round layer cake. There’s a hard line between the liquid metal core and the putty-like rock mantle. But maybe that boundary is a little fuzzier than we previously thought. Strange, continent sized blobs rest on the dividing line. These blobs are leaching material from the Earth’s core, extending arms out into the mantle, and sending core material up and out through magmatic plumes. No one’s completely sure how it’s happening. On this week’s episode, host Samir Patel and writer Robin George Andrews dig into the ancient isotopic signatures that are helping us better understand the material bubbling up from the depths of our planet. This topic was covered in a recent story for Quanta Magazine.

  • A New Quantum Math of Cryptography

    26/08/2025 Duración: 27min

    We’re living in the golden age of cryptography. Since the 1970s, we’ve had more confidence in encryption than ever before. But there’s a difference between confidence and absolute certainty. And computer scientists care a lot about that difference. The search is always on for better, more secure secrets. But is it possible for digital security to be truly, provably unbreakable? Maybe, with a little help from math and physics. On this week’s episode, host Samir Patel talks with ???????????????????????? computer science staff writer Ben Brubaker about a developing frontier of digital security: quantum cryptography.

  • How an Outsider Optimized Sphere-Packing

    19/08/2025 Duración: 28min

    How many oranges can you fit in a box? Mathematicians are obsessed with perfecting their answer to this question in not just our familiar three-dimensional world, but in higher and higher dimensions beyond it. For several decades, they’ve made only minimal progress toward finding an optimal solution. Then, this past April, an outsider to the field named Boaz Klartag posted a proof that bested these previous records by a significant margin. In this episode of The Quanta Podcast, host Samir Patel and Quanta math staff writer Joseph Howlett discuss how Klartag resuscitated an old technique that experts had abandoned decades earlier to optimize sphere packing in any arbitrarily high dimension.

  • 'It's a Mess': A Brain-Bending Trip to Quantum Theory's 100th Birthday Party

    12/08/2025 Duración: 29min

    As far as we know, quantum mechanics is a universal theory that explains matter and light more or less perfectly. It shows us why atoms don’t collapse and why electrons don’t spiral into the nucleus of the atom. It explains why glass is clear, why grass is green, why the sky is blue. But no one fully understands how the math of quantum mechanics connects with the reality we live in. One could spend a lifetime getting into the weeds and still have unanswered questions. In honor of quantum mechanics’ 100th birthday, host Samir Patel talks with Quanta physics staff writer Charlie Wood about his recent journey to the birthplace of quantum mechanics, a German island in the North Sea. On Helgoland, Charlie asked physicists many questions about many worlds over many beers.

  • How Smell Guides Our Inner World

    05/08/2025 Duración: 22min

    When some people smell the molecule benzyl acetate, they identify a distinctly banana-y scent. But when others sniff the same compound, they get hints of nail polish remover. How can this be? Smell is a tricky sensory process to pin down. Our perception of scents is wide-ranging and often depends on lived experience. But researchers are building a deeper understanding of the processes underlying our noses’ elusive machinery. In this episode, host Samir Patel and Quanta biology staff writer Yasemin Saplakoglu explore the invisible sense that shapes our reality, from nostalgic childhood fragrances — lavender, old books — to familiar irksome odors — skunks, garbage. This topic was covered in a recent story for Quanta Magazine. Each week on The Quanta Podcast editor in chief Samir Patel speaks with the people behind the award-winning publication to navigate through some of the most important and mind-expanding questions in science and math.

  • Audio Edition: How 'Event Scripts' Structure Our Personal Memories

    31/07/2025 Duración: 24min

  • When ChatGPT Broke an Entire Field

    29/07/2025 Duración: 29min

    The study of natural language processing, or NLP, dates back to the 1940s. It gave Stephen Hawking a voice, Siri a brain and social media companies another way to target us with ads. In less than five years, large language models broke NLP and made it anew. In 2019, Quanta reported on a then-groundbreaking NLP system called BERT without once using the phrase “large language model.” A mere five and a half years later, LLMs are everywhere, igniting discovery, disruption and debate in whatever scientific community they touch. But the one they touched first — for better, worse and everything in between — was natural language processing. What did that impact feel like to the people experiencing it firsthand? Recently, John Pavlus interviewed 19 current and former NLP researchers to tell that story. In this episode, Pavlus speaks with host and Quanta editor in chief Samir Patel about this oral history of “When ChatGPT Broke an Entire Field.” Each week on The Quanta Podcast, Quanta Magazine editor in chief Samir Pat

  • Is Mathematics Mostly Chaos or Mostly Order?

    22/07/2025 Duración: 27min

    As weird as it sounds, infinity comes in many shapes and sizes. And attempting to quantify it is sort of like a dog chasing its own tail. Or like infinities chasing infinities infinite numbers of times. But some mathematicians are obsessed with the quest. In this episode, host Samir Patel and ???????????????????????? math editor Jordana Cepelewicz probe the bizarre edges of the mathematical universe, a realm *almost* impossible to put into words. This topic was covered by Greg Barber in a recent story for ???????????????????????? ????????????????????????????????. Each week on ???????????? ???????????????????????? ????????????????????????????, ???????????????????????? ???????????????????????????????? editor in chief Samir Patel speaks with the people behind the award-winning publication to navigate through some of the most important and mind-expanding questions in science and math.
