3D Worlds
Step inside the experiments
Six real-time 3D games built on the same physics as the lessons. They run in your browser on phones, tablets and computers — no download.
Double-Slit Range
Fire electrons one at a time through two slits in a 3D lab and watch the impossible stripes build up — then switch on the which-path detector and destroy them.
Enter worldOrbital Diver
Swim through real hydrogen orbitals, each drawn from tens of thousands of simulated position measurements, and hunt for where the electron is most likely to be.
Enter worldTunnel Runner
Race a wave packet down a neon corridor of energy barriers. Your odds of tunnelling through each wall come from the exact quantum formula.
Enter worldBloch Sphere Command
Steer a qubit around a glass Bloch sphere with quantum gates. Reach each target state in the fewest moves.
Enter worldStern–Gerlach Beamline
Build a beamline of tilted magnets, fire silver atoms through it, and prove that measuring spin one way erases what you knew the other way.
Enter worldCollider Control
Run a particle detector: read tracks, curvature and calorimeter showers to identify what each collision made.
Enter worldBuilt with three.js and WebGL. Every world has a 2D lab twin inside its chapter.
