Physics
Schrödinger 2D
The quantum double-slit experiment: |ψ|² interference.

What happens
The double-slit experiment run honestly: a single quantum wave packet meets two slits, passes through both, and interferes with itself into the striped |ψ|² pattern. Switch to phase view to see the wave's hidden clockwork, or draw your own walls with the mouse and invent a new experiment.
Equations used in the module
Equations iħ ∂ψ/∂t = −(ħ²/2m) ∇²ψ + V ψ P(x, y) = |ψ|², fringes: Δy = λ L / d one particle at a time, and still fringes
