A camera was not always needed to "capture" a thought. In the late Victorian era, a few experimenters pressed photographic plates to foreheads and claimed the developed marks were images of the mind. In this episode of Math! Science! History! , we trace the strange rise of "thought photography," why it sounded plausible in an age of new invisible forces, and what these experiments reveal about tec...

What do you say when someone doesn't trust science? In this Flashcards Friday episode, I share practical, evidence-based ways to talk about science with skeptics, without attacking, shaming, or arguing past each other. This episode focuses on how evidence actually works , why people reject scientific claims, and how scientists and science communicators can lower defensiveness by explaining methods...

Episode Overview In the 1660s, two towering thinkers,  Thomas Hobbes and Robert Boyle,  clashed over a strange new machine: the air pump. What looked like a technical disagreement about air and vacuum quickly became something much larger. This episode examines how Boyle's experimental approach and Hobbes's philosophical skepticism shaped the foundations of modern science, and why their dispute sti...

The Sun Dagger on Fajada Butte in Chaco Canyon is a powerful reminder that understanding is built slowly. Long before textbooks and lab reports, careful observers tracked repeating patterns in light and season, and a community carried that knowledge forward. In today's Flashcards episode, we use the Sun Dagger as a practical thinking tool for modern life: watch first, listen second, explain last ....

More than a thousand years ago, the Ancestral Puebloans built a working solar calendar without clocks, written mathematics, or mechanical instruments. Etched into stone at Fajada Butte in Chaco Canyon , the Sun Dagger used light and shadow to track solstices and equinoxes with remarkable precision. In this episode, we explore how the Sun Dagger worked, why its spiral design mattered, and what it r...

Before Isaac Newton's ideas reshaped Europe, his work struggled to gain traction in Italy. This episode revisits the remarkable life of Laura Bassi, the first woman in history to hold an academic chair, and the physicist who championed Newtonian physics against fierce intellectual and social resistance. In 1776, Laura Bassi achieved a historic milestone, becoming the first woman in the world to ho...

A viral multiplication spiral once attributed to Nikola Tesla opens the door to a much older mathematical story, one rooted in ancient Sumerian and Babylonian base-60 mathematics. In this episode, we explore how sexagesimal counting shaped everything from clocks and geometry to modern science, and how ideas are often misnamed after the most famous figure rather than the original innovator. Along t...

In this repost episode of Math! Science! History! , Gabrielle Birchak speaks with Professor Gillen D'Arcy Wood, author of The Wake of the HMS Challenger: How a Legendary Victorian Voyage Tells the Story of Our Ocean's Decline .
