    FLASHCARDS! Research that Sits in the Margins
    Feb 27 2026

    A clean success story is rarely the whole story. In this Flashcard Friday episode of Math! Science! History!, Gabrielle Birchak offers a simple method for spotting the people who made breakthroughs possible but did not become the headline.

    In the Margins episode gives you three practical questions you can use on any science story to find hidden contributors in author lists, acknowledgments, lab records, and patent filings. Save this episode and use it as your listening companion heading into Women's History Month.

    What you'll learn (because the footnotes have feelings)

    1. How to spot hidden contributors quickly by asking who touched the evidence, who did the work, and who kept the record.

    2. Where credit actually shows up in science writing, including author order, acknowledgments, methods sections, and contributor role statements.

    3. How the "simple story" gets rewarded and how that reward system can hide women's contributions.

  • Hidden Inventors: Black Women, Patents, and Lost Credit

    Hidden Inventors: Black Women, Patents, and Lost Credit
    Feb 24 2026
    In this episode of Math! Science! History!, Gabrielle Birchak traces the paper trails behind Black women inventors whose ideas reshaped ordinary life, from laundry tools and home design to security systems and medical devices. You will hear how patents, assignments, licensing, and missing records shaped who got credit and who got paid, and why some inventions became household standards while their inventors stayed unfamiliar. This story is about engineering, documentation, and what happens when innovation meets the economics of recognition. What You'll Learn in This Episode Follow the Paper Trail How patents and archives function as evidence, and why the existence of a patent does not guarantee wealth, credit, or commercialization. How ownership can shift through assignments and intermediaries, changing who controls the rights and who benefits financially. How inventions become "invisible" once they become normal, and how race and gender shaped which names survived in popular history. Five Resource Links 1.

  • Benjamin Banneker: The African-American Astronomer who shaped D.C.

    Benjamin Banneker: The African-American Astronomer who shaped D.C.
    Feb 17 2026
    Benjamin Banneker used math, astronomy, and publication to claim space in a country that tried to deny him authority. This episode follows his path from a Maryland farm to almanacs that carried his name across the young republic, and to the 1791 boundary survey work that helped set the lines of the new federal district. What You'll Learn 1. How Banneker became an astronomer without a formal scientific education and why an ephemeris inside an almanac mattered so much in the late 1700s. 2. What Banneker actually did in 1791 during Andrew Ellicott's boundary work, and why later stories about his role in Washington's design grew beyond the record. 3. How publishing changed his life by carrying his calculations, voice, and reputation into a wider public, starting with the 1792 almanac (issued in 1791) and continuing through 1797.

  • Victorian Thought Photography

    Victorian Thought Photography
    Feb 10 2026
    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 technology, interpretation, and scientific method. What Develops in the Dark What you'll learn in this episode: 1. Who tried to photograph thoughts - How Hippolyte Baraduc and Louis Darget used photographic plates as instruments, then read the resulting traces as evidence of emotion, soul, or mental imagery. 2. Why the idea felt scientific at the time - How late-19th-century discoveries made invisible phenomena feel newly recordable, especially after X-rays reshaped what "photography" could mean. 3. What can go wrong (and right!) when images look like proof - Why noisy signals, chemical artifacts, and human pattern-finding can produce results that feel conclusive long before they are. Sources "Psychicones: Visual Traces of the Soul in Late Nineteenth-Century Fluidic Photography" (Nicolas Pethes, Medical History, 2016) "Imaging Inscape: The Human Soul (1913)" (The Public Domain Review on Baraduc's methods and plates) "Discovery of the X-ray: A New Kind of Invisible Light" (National Museum of Health and Medicine) 🔗 Explore more on our website: mathsciencehistory.com 📚 To buy my book Hypatia: The Sum of Her Life on Amazon, visit https://a.co/d/g3OuP9h ☕ Support the Show: Coffee!!

  • FLASHCARDS! Talking to Science Skeptics

    FLASHCARDS! Talking to Science Skeptics
    Feb 6 2026

    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, uncertainty, and values clearly. If you care about public trust in science, this episode offers tools you can use immediately.

  • Hobbes vs. Boyle: Who Decides Scientific Facts?

    Hobbes vs. Boyle: Who Decides Scientific Facts?
    Feb 3 2026
    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 still echoes today in debates over expertise, public trust, and the role of scientists in public policy. From the invention of "virtual witnessing" to modern struggles with misinformation, this is a story about how facts become believable, and what happens when trust breaks down. What You'll Learn Why experiments alone do not create trust - You'll learn how Boyle's air-pump experiments required not just data, but carefully crafted descriptions and shared norms to make results credible beyond the room where they occurred. What Hobbes was really worried about - This episode explains why Hobbes objected to experimental science, not because he rejected evidence, but because he feared the political and social consequences of letting small groups "certify reality." How this 17th-century dispute explains modern science debates - From climate models to medical guidelines, you'll see how today's arguments over evidence, institutions, and public policy replay the same structural tensions Hobbes and Boyle exposed centuries ago. 📚 Resources & Further Reading Leviathan and the Air‑Pump - Steven Shapin & Simon Schaffer New Experiments Physico‑Mechanicall, Touching the Spring of the Air - Robert Boyle Royal Society - History & motto Nullius in verba Pew Research Center - Public trust in scientists and policy debates (Nov. 2024 report) Shapin, Steven.
