Full Interview: The Hidden Math Behind Everything Aug 27, 2026

Show notes

Jordan Ellenberg tells Hakeem that math isn't just about numbers. It's about everything. The mathematician and bestselling author shares how AI models are trained through trial and error, why geometry secretly governs everything from family trees to statistical correlation, and why uncertainty, not certainty, is the true language of the universe. From new dimensions to hurricanes we can't quite predict, Jordan and Hakeem trace math's fingerprints across physics, language, and daily life in a preview of his upcoming book, Don't Be Too Sure.

Certainty Is Overrated Aug 25, 2026

Show notes

Jordan Ellenberg finds mathematical certainty overrated. Calming our fear of the unknown, the mathematician joins Hakeem to explore why math, contrary to popular belief, is less about proof and more about probability. He traces uncertainty's surprisingly recent arrival in mathematical history and its deep ties to quantum physics. Jordan also unpacks the difference between what's unknown and what's fundamentally unknowable, why hurricanes and earthquakes are "certain u

Next Dimension Geometry Aug 20, 2026

Show notes

Jordan Ellenberg says geometry isn’t about shapes. It’s about distance. In a tour of geometry far stranger than anything from high school, the mathematician breaks down how our ancient understanding of triangles evolved into the invisible architecture behind AI, family trees, and human relationships. Minds expand as we ask why the "closeness" between two ideas is a literal angle in a vast multi-dimensional space, and what can a 19th-century novella about a talking square teach us about worlds we'll never see?

AI’s Hidden Math Aug 18, 2026

Show notes

Jordan Ellenberg has good news: artificial intelligence is just math you can actually understand. The mathematician joins Hakeem to pull back the curtain on how large language models really work, revealing that the "miracle" of AI is closer to trial and error scaled up billions of times than anything resembling thought. Jordan breaks down why the process works so well, how every word becomes a point in a space with hundreds of dimensions, and why your chatbot's "personality" is engineered, not accidental.

Full Interview: Hobbits, Neanderthals, and Dragon Man Aug 13, 2026

Show notes

Ella Al-Shamahi explores what it means to be human. She reveals the surprising truth that our ancestors shared the planet with at least seven other human species as recently as 50,000 years ago. Ella and Hakeem dig into Neanderthal culture and the mysterious Denisovans who were identified from a single finger bone. Then Ella shares something more personal: her own journey from creationist to one of the leading voices in paleoanthropology.

Guest Bio:

Ella Al-Shamahi is a paleoanthropologist, explorer, and presenter based in London. She specializes in human evolution and has conducted fieldwork in some of the world's most dangerous and remote regions in search of fossil evidence of our earliest ancestors. She is a TED speaker and has appeared in numerous science documentaries, including hosting NOVA and BBC’s five-part series HUMAN, available on the PBS App and NOVA’s website.

Creationist to Evolutionary Biologist Aug 11, 2026

Show notes

Ella Al-Shamahi set out to disprove the theory of evolution. Now she’s one of its greatest advocates. In this deeply personal conversation, Ella tells Hakeem her story. She started university as an avid creationist missionary with the intention of disproving evolution, and then her world started to fall apart. This candid conversation covers what the journey from creationist to paleoanthropologist actually looked like, and the evidence that shifted her thinking. It is a path with personal costs and the impact of changing worldviews. It's a thoughtful reflection on science, identity, community and why empathy matters more than argument when deeply held beliefs meet new evidence.

Rethinking Neanderthals Aug 06, 2026

Show notes

Ella Al-Shamahi thinks Neanderthals have a reputation problem, and the science backs her up. For decades, the word "Neanderthal" has been shorthand for something primitive and brutish. But the archaeological record tells a more nuanced story. Ella joins Hakeem to explore what we actually know about our closest ancient relatives: how they looked, how they lived, what their culture reveals about their inner lives, and if we would even recognize one walking around today. They also dig into the remarkable story of the Denisovans, a species shrouded in mystery and identified first not from a skull or skeleton, but from a single finger bone.

Real Hobbits? Aug 04, 2026

Show notes

Ella Al-Shamahi says the iconic picture of human evolution is all wrong. She joins Hakeem to take apart the conventional image of the straight-line march of evolution from ape to modern human. The fossil and DNA record tells a far more complex story. As recently as 50,000 years ago, our ancestors shared the planet with at least seven other human species. From the small-statured Hobbits of Indonesia to the mysterious Denisovans of East Asia, the world was very different, and new research suggests that roughly 20% of our genome may trace back to an unknown “ghost lineage” of human species. Human evolution wasn't a straight line, it was a sprawling, interconnected web.

Full Interview: The Future of AI and Us Jul 30, 2026

Show notes

Daniela Rus brings robots and AI together, and as a computer scientist and roboticist at MIT, she's here to set the record straight. She's not just studying AI from the outside. She's building it, and finding ways to make everyday life better. Daniela joins Hakeem to pull back the curtain on what AI actually is, how it really works, and where it is genuinely headed. What happens when AI leaves the cloud and moves into your phone, your car, and even your body? And what does a tiny worm with 302 neurons have to do with the future of machine intelligence? From the history of AI to so-called “liquid networks,” self-driving cars, humanoid robots, and an origami surgeon you can swallow, this conversation covers the full scope of what MIT's most ambitious minds are building right now.

AI Origins Jul 28, 2026

Show notes

Daniela Rus is cutting through the AI hype and headlines to give us a real understanding of its future. As Director of MIT's Computer Science and Artificial Intelligence Laboratory, she has a front-row seat to what AI actually is, how it actually works, and what it can and cannot do. Daniela joins Hakeem to map out the full landscape of a field that is far richer than chatbots and large language models. What are the different types of AI we have today, and how does each one work? Why did methods invented 40 years ago suddenly start working? And how does Daniela envision the impact of AI on the job landscape of the future?
