From Conway and Guy’s 1966 question about a uniform tetrahedron to modern demonstrations of monostability via uneven weight, this episode unpacks a surprisingly deep journey. We delve into the idea of an obtuse path that fixes the center of mass in a tiny stable zone, the brutal engineering math that demands a heavy core thousands of times denser than the light shell, and the real-world challenges of making that physics work with carbon fiber frames, tungsten carbide cores, and glue tolerance...

Anders Larson and Shea Parkes discuss using GenAI applications with coding agents to simulate healthcare costs.  They revisit the distinction between large language models (LLMs) and the applications that wrap them.  They then use some newer GenAI application functionality to generate some simulated healthcare cost distributions.  During their discussion they explore what domain knowledge the modern LLMs already have, and how to supplement that with their own domain expertise.

Kim Montague, I Have, You Need: The Utility Player of Instructional Routines ROUNDING UP: SEASON 4 | EPISODE 3 In sports, a utility player is someone who can play multiple positions competently, providing flexibility and adaptability. From my perspective, the routine I have, you need may just be the utility player of classroom routines. Today we're talking with Kim Montague about I have, you need and the ways it can be used to support everything from fact fluency to an understanding of algebraic

In this episode of Now I Get It, I explore why simply memorizing formulas in math—or blindly trusting any model—can lead to catastrophic outcomes. I take a hard look back at the financial meltdown and show how a lack of deep understanding, not just fraud, helped steer us into crisis. It wasn’t that the models themselves were flawed; it was that people used them without grasping their limits, breaking the very assumptions they were built on.From there, I connect the dots to today’s frontier:

The mathematical area of topology is all about figuring out what truly defines a shape. Famously, topologists consider a coffee cup to be the same as a doughnut because one can be turned into the other without cutting or gluing — what defines and relates these two shapes for a topologist is that they have a single hole.As you might imagine, if you have ever tried to drink coffee out of a doughnut, topology has traditionally been part of pure mathematics. Topological data analysis (TDA), however,

In this Flashcard Friday follow-up to Tuesday’s interview with Dr. Kanisorn Wongsrichanalai of the Massachusetts Historical Society, we revisit the numbers that changed the course of history. During the Revolutionary War, smallpox was more dangerous to the Continental Army than the British. By comparing mortality rates, George Washington made a bold, science-driven choice: inoculate his troops. The math was simple but profound, 30% risk of death without inoculation versus just 2% with it. This

We start with Steno’s law and the idea that older stuff lies deeper, then ride into the archaeologist’s toolkit for turning messy ground into a timeline: the Harris Matrix, context by context. You’ll learn why physical height isn’t a guaranteed guide to age, what reverse or inverted stratigraphy looks like in the real world, and how deposits can be disturbed by people and nature to flip the apparent order. We’ll unpack common pitfalls—palimpsests, bioturbation, and redeposited fills—and show ...

We dive back into the Mesozoic to trace ichthyosaurs from land reptiles to apex marine predators. Learn how their convergent body plan, thunniform swimming, huge eyes, warm-blooded metabolism with insulation, and live birth powered a vast oceanic empire—and why a changing world eventually reshaped their fate. We also recount Mary Anning’s role in their discovery and what this saga reveals about specialization and ocean change today. Note: This podcast was AI-generated, and sometimes AI can m...

In this passionate and powerful episode of Tier 1 Interventions, Cheri Dotterer and Jonily Zupancic are joined by fellow educators Kirk, Teresa, Kathy, and Natalie for a live conversation on the deeper mission behind math education. This isn't just about teaching content—it's about the moral responsibility to teach it well.🔥 Hear real stories from teachers and tutors on the frontlines of a broken system, and discover why teaching math the way we were taught just doesn’t cut it anymore.🎯

In this episode, Anna Rose and Kobi Gurkan chat with Arnaud Brousseau and Jack Kearney from Turnkey about verifiable key management using trusted execution environments (TEEs). They share how their past work on custody and validators inspired them to build more sophisticated key management tools and some of the qualities TEEs enabled. The discussion covers a range of challenges and techniques: the role of remote attestation and reproducible builds in ensuring trust, strategies to prevent downgrade

Tim Harford investigates some of the numbers in the news. This week:US President Donald Trump claims he has ended seven “unendable” wars. Is that true?Chancellor Rachel Reeves says the UK was the fastest growing economy in the G7 for the first six months of 2025. What do you need to know about that stat?The Daily Mail has described a recent scientific paper as describing a global cancer “explosion”. Is that the whole story?And why have Oxford and Cambridge dropped down a university league table?If

The Romans are here, in ROME! Discover the dramatic rise and fall of the Roman Empire, its lasting global impact, and the fascinating (and sometimes contentious) question of who inherited its crown. Then, meet Boethius, the last classical scholar, whose time on death row led to The Consolation of Philosophy. This episode unpacks his brilliant philosophy of causation, free will, and how god knows the future without pre-determining our choices. We'll explore Aristotle's Sea Battle paradox, Boethius's

In this episode, Kathy and Linda talk with Manyphay Viengkham, an accomplished technology leader whose career spans energy innovation, systems engineering, and entrepreneurship. With degrees in biochemistry and computer science, Manyphay has built a career defined by curiosity, continuous learning, and resilience—navigating roles in major companies like GE and Honeywell before launching her own consulting business. Together, they explore: How following her curiosity led from science to techno...

An overview of word embeddings, explaining that they are numerical representations of words—often in the form of vectors—that capture their semantic and contextual relationships. The need to transform raw text into numbers arises from the inability of most machine learning algorithms to process plain text, making word embeddings a fundamental tool in natural language processing (NLP). The video describes various applications of embeddings, including text classification and named entity recognition

We dissect the core mystery of quantum entanglement—how joined states defy classical separability and persist across great distances. From the EPR paradox to Bell’s inequality, we explain how reduced density matrices and von Neumann entropy quantify entanglement, and how this nonlocal resource powers quantum communication and computation (superdense coding and teleportation). We also touch on speculative links to the emergence of time and spacetime, showing why entanglement sits at the heart ...

A deep dive into the Nobel-winning tool that uses a tightly focused laser to trap and manipulate microscopic objects. We’ll unpack the physics of gradient and scattering forces, the regimes of ray optics versus dipole approximation, and the practical tricks like holographic traps and optoelectronic tweezers. From measuring molecular motors in biology to arranging atomic quantum arrays, this episode reveals how light can hold, move, and even levitate the small world—and why wavelength choices ...
