Brownian Motion 2D — Nanoparticle Diffusion Simulator

Canvas2D companion to the 3D nanoparticle diffusion lab: Einstein-Smoluchowski physics, live trajectories, and a measured-vs-theoretical MSD plot.

Nanotechnology & MEMS2DModerate60 FPS📱 Mobile-adapted⇄ 3D version

This 2D companion drives the same Einstein-Smoluchowski diffusion physics as the 3D version through a plain canvas view: adjust temperature, particle radius, particle count and fluid viscosity, and watch the live mean-squared-displacement plot track the theoretical 4Dt line in real time.
