What if you could watch molecules move in real time? Nobel Prize-winning chemist Ahmed Zewail made that possible by pioneering femtochemistry, capturing chemical reactions in quadrillionths of a second.

In this Flashcards Friday episode, Gabrielle Birchak uncovers Zewail’s remarkable journey: from his modest childhood in Egypt, to facing challenges as an immigrant scientist in the U.S., to transforming the very foundations of chemistry. Along the way, we explore how his resilience, persistence, and vision helped him rise above obstacles and leave a legacy that continues to inspire scientists across the globe.

Three Things You’ll Learn

1. How Ahmed Zewail invented femtochemistry and why it transformed our understanding of chemical reactions.
2. What adversities Zewail overcame as a Sunni Muslim scientist from Egypt working in the U.S. and navigating skepticism.
3. Why resilience matters in science — and how Zewail’s persistence can inspire your own path.
