# diffusion
Diffusion is the drift of things — particles, heat, sound, even data — from where they're concentrated toward where they aren't, driven by nothing more than random motion at a small scale. This collection lets you watch that spreading happen: Random Walk and Brownian Motion show the underlying jitter of individual particles, Particle Diffusion and Cell Membrane Diffusion apply it to gases and living cells, while Fourier Heat Equation and Urban Heat Island track how warmth spreads through solids and cities. Even Hash Functions makes the cut, since a good hash scrambles input the same way diffusion scrambles particles — small changes cascade everywhere. Filter here if you want to see order collapse into randomness, one step at a time.

Facts about this collection
- 10 simulations and 1 article carry the diffusion tag, spanning physics, biology, acoustics and cryptography.
- Random Walk and Brownian Motion both model the same random-jitter process at different scales — one abstract, one physical (nanoparticles).
- Fourier Heat Equation is the only sim here that explicitly models boundary conditions, making it the deepest look at heat diffusion in the set.
- Real-Time Fluid Simulation solves the Navier–Stokes equations, showing diffusion as one term inside a full fluid-flow model rather than in isolation.
