Physics and chemistry
Matter from the bottom up: atoms, the forces between them and, eventually, the quantum rules underneath, simulated live on your GPU.
The atoms, galaxies and orbitals run on WebGPU, in recent Chrome, Edge and Safari, and in Firefox on Windows and macOS. The solar system runs anywhere.
WebGPU · Up to a million atoms
Gas, liquid, crystal
Atoms that condense, freeze and flow from one force law.
WebGPU · Toomre & Toomre
Colliding galaxies
Two spirals pass and tear out tidal tails.
JPL Horizons · General relativity
Solar system
Real orbits, and Einstein's 43″ measured live.
WebGPU · Schrödinger, exactly
Hydrogen's orbitals
Every orbital to n = 4, and superpositions that move.
WebGPU · From years to billions
Riding the galaxy
The planets round the Sun, the Sun round the Milky Way.
