Angie shares the story that sparked Espwa's mission, the stark realities behind maternal and infant mortality, and what "progress" looks like...

Science fiction does not need to predict the future to matter. It matters because it trains the mind. In this Flashcards Friday episode, Gabrielle Birchak uses four unforgettable Star Trek moments to show how stories can pressure-test ideas, preview consequences, and build shared language that helps real science move faster and more responsibly. From the chaos of "Spock's Brain" to the furry avala...

In this episode, I tell the story of Mari Wolf , who wrote sharp, unsettling science fiction in the early 1950s while also working in Computing at Jet Propulsion Laboratory . Her life sits at the intersection of math, imagination, and a Los Angeles culture that treated the future as something you could sketch, test, and argue about late into the night. We follow her through the worlds that shaped...

How does knowledge survive when libraries burn, devices are seized, and archives come under threat? In this Flashcards Friday episode of Math! Science! History! , Gabrielle Birchak takes a closer look at what it actually means to preserve knowledge in the present moment. Using three short flashcards, this episode explores redundancy, cloud storage, and practical threat modeling for scholars, journ...

What does it take to preserve knowledge when libraries burn, records disappear, and history itself is under threat? In this episode of Math! Science! History! , Gabrielle Birchak takes a closer look at the life and work of Adolphe Rome, a meticulous Belgian historian of science whose devotion to ancient mathematics and astronomy reshaped how we understand figures like Ptolemy, Hypatia, and Theon o...

A clean success story is rarely the whole story. In this Flashcard Friday episode of Math! Science!

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 ....
