Active Matter Lab. A growing library of run-anywhere physics simulations — start now with the MIPS toolkit, Vicsek flocking, and the Ising model, and get a fresh one every week (Langevin dynamics, the 2D gas, phase diagrams, and more). Every notebook runs in your browser via Google Colab with nothing to install, animates the physics as it happens, and explains it in clear, intuitive language. Start with a free trial; cancel anytime.
