EXPERIMENT 003 / HYDROGEN OBSERVATORY
Where an electron could be.
An electron in hydrogen has no fixed orbit. Its quantum state describes a distribution of possibilities. Cut through that distribution and discover the shapes inside.

ONE ELECTRON / THIRTY STATES
A shape of possibility.
Find the nodes. Reveal the phase. Move through a world measured in Bohr radii.
THE MODEL / HYDROGEN
A slice of a quantum world.
Choose an energy shell and angular quantum numbers, then move a plane through the orbital. Brightness shows probability density; color can reveal the wavefunction’s phase. Dark nodes separate regions where the wavefunction changes sign or vanishes.
The viewer evaluates stationary solutions for one electron around a fixed proton. Changing states is a comparison, not a simulation of an electron absorbing light. Spin, relativistic effects, and other atoms are outside this first model.
The radial plot answers a different question: how likely is the electron to be at a given distance, after adding up all directions?
A PERMANENT RECORD
First the slice. Then the volume.
v0 establishes the physics and the controls in two dimensions. The v1 viewer brings these wavefunctions into a fully three-dimensional orbital experience, while preserving this first version.
