Stern–Gerlach and spin experiments
Fire spin particles through a virtual Stern–Gerlach magnet, run entangled pairs between two labs, and look inside the particle to see how the mechanism produces the quantum results.
3D Stern–Gerlach Experiment →Configure your own magnet, fire spin particles from any angle and see where they land.
Alice & Bob's Virtual Labs →Run entangled-particle trials between two labs and watch the statistics build up live.
The Six Stages of Causality →Step through an interactive 3D experiment and follow the chain of events between two particles.
Inside the Particle →Step through the spin particle's simple structure and see how superposition and collapse arise from it.
