This week, Pappus of Alexandria, a pivotal figure in 4th-century mathematics. Often considered one of the last great Greco-Roman geometers, Pappus compiled the monumental Synagogue, a comprehensive collection that sought to revive classical Greek geometry. In this episode: A candid look at Pappus's personality and his notorious public critique of the female mathematician Pandrosion and her student. Pappus’s distinction between "plane," "solid," and the more expansive "linear" problems. Concepts like

In this episode of Ordinarily Extraordinary – Conversations with Women in STEM, Kathy and Linda sit down with Lawanda Parnell, a retired technology and utility leader whose career began at IBM in the early 1980s and spanned decades of innovation and leadership. Lawanda shares her journey from studying business administration with a strong math and computer science foundation at the University of Florida, to becoming one of the few Black women in tech during her era, to leading large-scale pro...

With the news that there’s a new computing education podcast (The Rest is Teaching) I thought I’d put together a selection of podcasts which might be of interest to computing educators. The first set are more specifically about teaching computing, or computing careers but the second set are… a little more random. Perhaps you have […]

Ich wurde beauftragt, einen Bauplan für eine Minecraft-Festung mit kreisförmiger Grundfläche anzulegen. Das schickt mich erstmal auf eine Reise in die Geschichte der Pixel, die in Wirklichkeit gar keine kleinen bunten Quadrate sind.

Join Danny Moore and Aaron Jurgaitis as they discuss tertiary and quaternary care from an actuarial perspective. Danny and Aaron discuss: Definitions around the different levels of care, from primary up to quaternary Specifics around the types of care delivered in the specialized facilities that deliver this care, and The key themes actuaries need to keep in mind when analyzing data that include these types of services. Aaron shares information from his background of performing analysis for

Send us a text Does your math class feel like only a handful of students ever raise their hands while the rest stay silent? Or maybe your students avoid sharing out of fear of being wrong? You’re not alone—many teachers face this challenge. In today’s episode, we’re diving into Step 3 of Word Problem Workshop: the Share, and how it can transform your math classroom into a motivated community of problem-solvers. When I taught both 1st and 5th grade, I noticed the same pattern—students hesitate...

In this episode of Math! Science! History!, Gabrielle uncovers the fascinating story of quasicrystals, once thought impossible, now proven to exist both in the lab and in meteorites from space. Listeners will learn how quasicrystals challenged centuries of crystallography, the math that explains their strange patterns, and the surprising ways they’re used today, from non‑stick coatings to futuristic photonics. Three Things You’ll Learn Why quasicrystals broke the old definition of crystals and

In this long-awaited followup to our popular Math Club Junior episode, Pete and Noah are back with Mrs. Morrison’s class, as chaperones on a field trip to the local zoo. Listen in as our group of Junior Zookeepers meet a whole new cast of zany characters, and once again learn that math is everywhere if you just look around. And just like last time, this story is full of interesting math challenges for listeners in the upper elementary grades to enjoy and solve.   • A slide deck with visuals to go

Apertem os cintos e preparem-se para viajar pela História da UFRJ.Abrimos uma nova série de entrevistas com quem viveu a história. Neste segundo episódio, recebemos os professores Carlos Frederico Vasconsellos e Lucia Maria Vasconsellos — aluno e docente da UFRJ entre as décadas de 1970, 1980 e 1990 — para revisitar o ambiente da Análise na época. Entre bastidores e causos, ele relembra os estilos de trabalho associados a figuras como o professor Luis Adauto Medeiros, mostrando como este professor

We explore Armenia’s colossal Vizhapakar dragonstones—basalt megaliths dating to the Chalcolithic around 4200–4000 BCE. Shaped as fish and cowhide figures, these markers sit at springs and irrigation corridors, revealing a sophisticated, region‑wide ritual system that tied water management to monumental labor. Through new dating and spatial analysis, we see how these 4,000+ year‑old stones encode social organization, sacred geography, and a worldview where water, ritual, and survival were dee...

We dive into A000351, the powers of five, from its tidy recurrence and generating function to the surprising ways it shows up across number theory, combinatorics, and geometry. Along the way we explore connections to Pisot-number phenomena, a divisor-sum–based lens on primality, counting integers with only odd digits, generating-function identities, and even a fractal-counting angle in the Sierpinski pyramid. We also glimpse neat infinite-series quirks: the sum of reciprocals of 5^n equals 5/...

Explore the birth of the capacitor era. In the 1740s, Kleist and Muschenbroek’s shocking experiments showed a glass jar could store energy; Benjamin Franklin identified the dielectric inside and coined the term 'condenser.' Jean-Antoine Nollet popularized the device and the name 'battery,' turning it into public spectacle and laying the groundwork for modern electronics and the enduring questions about electricity’s true nature.

Polaritons are bosonic quasi-particles formed when photons strongly couple to a material excitation (such as an exciton or a phonon), creating new mixed light–matter normal modes. This strong coupling leads to level repulsion (avoided crossing) that splits the system into upper and lower polariton branches, giving tunable light propagation inside materials. The result is a powerful platform for energy-efficient devices and quantum technologies, with phenomena like room-temperature polariton s...

We explore Mosasaurus, the apex marine lizards that ruled 94–66 million years ago. Learn how a stiff body and a powerful crescent tail propelled shark-like bursts, why double-hinged jaws and flexible skulls let them swallow large prey, and the surprising evidence for endothermy and live birth. We also trace their dramatic extinction at the K–Pg boundary—preserved in a Chicxulub tsunami deposit in Missouri—and what their rise and fall reveals about ancient oceans. Note: This podcast was AI-gen...
