Articles and video companions
Written explorations of physics, visualizations, and the ideas behind Imagining Physics videos.
Follow the path from Hamilton’s action to phase fronts, rays, the optical eikonal, and the caustic. Begin with a falling particle, then see how the same geometry appears in Kepler orbits.

Encode the search in one particle’s wave. Let the box’s energy spectrum supply the mixing, build the inverse with a forward wait, and explore probability flow and spin.

Find one answer among N candidates. Understand the two reflections, build the gates, and explore a sixteen-state example with interactive vectors and amplitude columns.

Carry an arrow around a loop, build a geodesic, compare neighboring paths, and follow a cloud in free fall.

Give a charge one push. Watch the field catch up, the pulse travel outward, and nearby test particles respond.

Explore stationary box eigenstates, Pauli spin current, and Bohmian trajectories.
Open notebook →
Compare collapse and trajectory-based pictures of beam splitting, interference, detection, and delayed choice.
Open notebook →
Explore Born equilibrium, non-equilibrium ensembles, and how Pauli spin current can accelerate Bohmian relaxation.
Open notebook →
Follow a spreading Gaussian packet, trajectory ensembles, and asymmetric free-packet motion in two dimensions.
Open notebook →
Follow individual trajectories, reveal the interference pattern with an ensemble, and explore equivariance.
Open notebook →
Explore spinor splitting, Bohmian guidance, and the contextuality of spin in Stern-Gerlach experiments.
