Gray-Scott model

The Gray-Scott model describes how two chemicals react and diffuse over time, creating complex patterns. Imagine placing two substances, A and B, in a space: chemical B converts A into more B, while B naturally decays and spreads out. This interplay of reaction, decay, and diffusion results in beautiful, evolving patterns such as spots or stripes. The model helps scientists understand pattern formation in nature, like animal markings or chemical reactions, by simulating how simple rules at the microscopic level lead to diverse macroscopic structures.
