The Schrödinger equation, made visible.

A pedagogical platform for physics, blending clearly written course notes with simulations you can tune and watch evolve in real time.

Typeset course notes with real LaTeX — the physics stays front and center.

Drag sliders and watch the potential and its eigenstates reshape instantly.

Stream a wavepacket in real time and scrub through its evolution frame by frame.

Modules

Parity, the graphical construction, and how many states a well holds.

Separable states, and degeneracy as lattice points on an ellipse.

3D electron density of hydrogen-like states, in spherical coordinates.

Successive measurements, collapse, and the Bloch sphere.
