Voronoi Cells and Their Applications

The video explores the concept of Voronoi cells, a geometric pattern found in nature, and their applications in various fields. It explains how these cells form during crystallization and their use in solving real-world problems like the cholera epidemic in London. The video also covers the greatest circle problem and mathematical modeling using Voronoi cells, concluding with a sponsor message from Brilliant.org.
