The Drunkard's Walk
Imagine being in the middle of a field and flipping a coin to decide whether to step North, South, East, or West.
Two Ways to Watch:
- 1 Walker: Watch the unique, winding path of a single particle.
- 50 Walkers: Watch a "Probability Cloud" expand. This simulates Diffusion (like perfume spreading in air).
Math Fact: The average distance from the center grows by the square root of time ($\sqrt{t}$).
