    The Alphabet of Brilliance: 8 LGBTQ+ Scientists Who Changed History | Pride Month Special

    For Pride Month, I profile eight scientists across eight identities in the 2SLGBTQI+ community. From the equations underpinning modern physics to the brain cells once dismissed as filler tissue, these researchers shaped the world we live in, often while hiding, fighting for, or paying dearly for who they were. Today I trace the lives of Sofia Kovalevskaya, Alan Turing, Margaret Mead, Ben Barres, Christopher Strachey, Magnus Hirschfeld, Paul Erdős, and Lozen, eight stories of brilliance that history tried, and failed, to erase. 3 Things You'll Learn in This Episode How a forged marriage opened the door to modern physics. Sofia Kovalevskaya couldn't attend university as a woman in Russia, so she found another way in, and ended up proving foundational theorems that every engineer and physicist still relies on today. Why the man who helped win WWII was punished by the country he saved. Alan Turing's codebreaking work is credited with shortening the war by years and saving millions of lives. Decades later, that same government prosecuted him for being gay, then put him on its currency. How "supporting" brain cells turned out to be running the show. Ben Barres's research overturned decades of neuroscience consensus about glial cells, and his own experience transitioning gave him a firsthand look at gender bias in science that became one of the most cited accounts of its kind.

    FLASHCARDS! You Are a Game Theorist!

    What if the negotiation strategies, workplace rhythms, and relationship instincts you've relied on your whole life already had names in mathematics? In today's FLASHCARDS! episode of Math! Science! History!, I break down three foundational concepts from game theory: dominant strategy, tit for tat, and Nash equilibrium, and connect each one to the everyday decisions, compromises, and unspoken social contracts you navigate all the time. Whether you're a math enthusiast or someone who swore they "weren't a math person," this episode reveals that you've been doing game theory your entire life without even knowing it. 🃏 In This Episode, You Will Learn: What a dominant strategy is and how to recognize when you're already using one, from sending that follow-up email to ordering your favorite dish at a restaurant. The fascinating history of tit for tat, the surprisingly simple strategy that beat out complex algorithms in Robert Axelrod's famous 1980s tournament, and how it mirrors the unspoken rules of your closest relationships. How a Nash equilibrium shows up in everyday conflict, and why the moment you and someone else silently agree to "stop pushing" is actually a mathematically stable outcome. 📚 Sources Von Neumann's 1928 minimax theorem is widely considered the founding document of modern game theory. https://en.wikipedia.org/wiki/Minimax_theorem John Nash received the Nobel Prize in Economic Sciences in 1994 for his pioneering analysis of equilibria in the theory of non-cooperative games. https://www.nobelprize.org/prizes/economic-sciences/1994/nash/facts Robert Axelrod's landmark book The Evolution of Cooperation (1984) explored how cooperation can emerge among self-interested agents, using his famous computer tournament in which tit for tat won. https://en.wikipedia.org/wiki/The_Evolution_of_Cooperation 📣 Calls to Action Subscribe & Review: If today's episode made you see your everyday decisions in a whole new light, please subscribe to Math!

    Game Theory Explained: The History, Math, and Masterminds Behind It

    In this episode, I'm covering the fascinating origin story of game theory, the mathematical framework that explains how we make decisions when our choices depend on what others do. From the chess board to the Cold War, from traffic jams to Nobel Prizes, game theory is hiding everywhere in plain sight. I explore the brilliant, sometimes tortured minds of John von Neumann and John Nash, walk you through the elegant math of the minimax theorem and Nash equilibrium, and show you how these ideas have shaped economics, artificial intelligence, biology, and even nuclear diplomacy. Whether you're a math lover or just someone who's ever wondered why traffic jams form out of nowhere, this episode will completely change the way you see strategy, competition, and cooperation in everyday life. What You'll Learn ·         The historical and mathematical context of the early 20th century that made game theory possible ·         What a "game" actually means in the mathematical sense, and why it's about far more than chess or poker ·         Who John von Neumann was and how his 1928 minimax theorem became the cornerstone of game theory ·         How John Nash, a young Princeton doctoral student, revolutionized the field with the Nash equilibrium ·         Why the Prisoner's Dilemma shows that rational individuals can end up with collectively bad outcomes Quote from the Episode "As far as I can see, there could be no theory of games without that theorem … I thought there was nothing worth publishing until the Minimax Theorem was proved." - John von Neumann Episode Resources ·         von Neumann, John. "Zur Theorie der Gesellschaftsspiele" [On the Theory of Games of Strategy]. Mathematische Annalen 100 (1928): 295–320. ·         Nash, John F. "Equilibrium Points in N-Person Games."
