Episode Overview:
Long before Europe adopted the concept of zero, the ancient Maya had already created one of the most sophisticated mathematical systems in the world. In this episode of Math Science History, host Gabrielle Birkjak uncovers the secrets of Mayan mathematics, from the elegance of their base-20 number system, to their revolutionary use of zero, to the celestial precision encoded in the Dresden Codex.

We explore how the Maya embedded math into everything from pyramids to calendars, and how European scholars like Ernst Förstemann helped rediscover their brilliance centuries later. This isn’t just a story about numbers, it’s a story about worldview, time, astronomy, and one of the most advanced mathematical traditions of the ancient world.

Three Things You’ll Learn in This Episode:
How the ancient Maya independently invented and used zero in a positional number system.

Why their base-20 (vigesimal) system was uniquely suited for astronomy and calendar cycles.

How the Dresden Codex survived colonialism and war to become a key to understanding Mayan math and astronomy.

Episode Overview

In this episode of Math, Science, History, host Gabrielle dives deep into the extraordinary—yet often overlooked—life and legacy of Mileva Marić, Albert Einstein’s first wife and intellectual companion. Far more than a footnote in Einstein’s story, Mileva was a brilliant physicist and mathematician in her own right. Together, the couple studied, collaborated, and may have laid the foundation for some of the most revolutionary scientific breakthroughs of the 20th century.

Gabrielle uncovers newly re-examined letters, analyzes quotes from Einstein’s professors and contemporaries, and presents biographical findings that shed light on Marić’s intellectual contributions to Einstein’s early work—especially during the years leading up to his famous 1905 Annus Mirabilis.

3 Things You'll Learn in This Episode:

How Mileva Marić helped shape Einstein’s early scientific thinking—and what letters and biographies reveal about their collaboration.

What Einstein’s professors and colleagues really thought about his student days—and why Minkowski called him a “lazybones.”

Why historians now believe Mileva Marić’s role in Einstein’s 1905 papers may have been more significant than previously acknowledged.

In this Flashcard Friday episode of Math! Science! History! host Gabrielle Birchak shines a light on the incredible story of Jacoba van den Brande, a seventeenth-century Dutch visionary who dared to imagine a world where women could be educated in mathematics, philosophy, and the sciences. Long before women had access to formal education, Jacoba not only excelled in math herself but also proposed the radical idea of an all-female academy. Join us as we explore her life, her bold vision, and how her ideas still echo through the halls of academia today.

The life and legacy of Jacoba van den Brande and her place in the history of mathematics.

The barriers women faced in 17th-century Europe when pursuing intellectual and academic opportunities.

Why Jacoba’s vision of an all-female academy remains relevant to ongoing conversations about equity and access in education.
