Episode Overview: What do black holes, a teenage genius, and a long ocean voyage have in common? In this Flashcard Friday episode of Math, Science, History, Gabrielle tells the incredible story of Subrahmanyan Chandrasekhar, who, at just 19 years old, sailed from India to England and made a discovery that would transform astrophysics forever. Armed only with a notebook and fresh ideas from quantum mechanics, Chandrasekhar calculated the limit of stellar collapse, now called the Chandrasekhar Limit, which revealed when a star collapses into a black hole. This isn't just a story about...

Leonardo da Vinci is often remembered for the Mona Lisa and The Last Supper—but he was so much more than a painter. In this episode, we uncover the Renaissance icon’s groundbreaking work in engineering, anatomy, and invention, as well as explore the quieter truths of his personal identity. We ask a powerful question: What might the world look like if everyone—regardless of gender or sexuality—could live and create as freely as Leonardo did, without fear of judgment? Join us as we journey through Leonardo’s notebooks, his unconventional relationships, and the brilliance he left...
