Diffusion limited aggregation (DLA)

Diffusion Limited Aggregation (DLA) is a process that models how particles in a fluid or gas randomly move and stick together to form complex, branching structures. Imagine particles drifting randomly until they hit and stick to an existing cluster, gradually creating intricate, tree-like patterns. This process is driven by diffusion—the particles’ random motion—and the tendency to adhere upon contact, resulting in formations resembling snowflakes or mineral deposits. DLA helps scientists understand pattern formation in natural systems, such as mineral growth, electrodeposition, and microbial colony shapes.
