The Impossible Walk That Invented Graph Theory | "Bridges of Königsberg"

The Impossible Walk That Invented Graph Theory | Bridges of Königsberg
In 1736, the people of Königsberg faced a simple challenge: could you walk through the city crossing all seven bridges exactly once? This seemingly innocent puzzle stumped everyone—until mathematician Leonhard Euler proved it was mathematically impossible and accidentally invented an entire field of mathematics.
🌉 What You'll Learn:

How the Seven Bridges of Königsberg problem works
Why Euler's solution was revolutionary
The birth of graph theory and its proof
How nodes, edges, and Eulerian paths changed mathematics
Why this 300-year-old solution powers Google Maps, social networks, and the internet today

📊 The Mathematical Breakthrough:
Euler transformed the bridge problem into an abstract graph with nodes and edges. His insight? For a path crossing every edge exactly once to exist, you can have at most TWO nodes with an odd number of edges. Königsberg had FOUR odd nodes—making the walk impossible.
🧠 Why Graph Theory Matters:
Graph theory isn't just abstract mathematics. It's the foundation of:

GPS navigation and route optimization
Social network connections (Facebook, Instagram)
Internet infrastructure and network design
Neural networks and brain mapping
Airline routes and delivery logistics

This video tells the story of how Leonhard Euler—a blind mathematician who wrote over 800 papers—looked at an "impossible" problem and created a new way of thinking that still shapes our world today.
