Math! Science! History!

Gabrielle Birchak

Why do some scientific breakthroughs look different up close than they do in our textbooks? How did math quietly shape the modern world? Math! Science! History! explores the human side of discovery, including the rivalries, the failed attempts, the bold ideas, and the marginalized voices behind the equations and experiments that changed science, technology, and everyday life. Hosted by Gabrielle Birchak, who holds degrees in mathematics and journalism, the show connects codebreaking, astronomy,
