The math behind Google Maps is based on finding the fastest route between two points. In this video, Veritasium explains how a breakthrough algorithm created by Edsger Dijkstra in 1956 became the foundation for modern navigation systems.
From the early days of computing to today’s advanced mapping software, the story shows how engineers developed smarter ways to calculate routes quickly and accurately across millions of roads around the world.
Why it matters:
Navigation apps help billions of people save time, fuel, and money every day. Understanding the mathematics behind them reveals how a simple idea evolved into one of the most widely used technologies in modern life.
