|Interactive Molecular Dynamics simulates up to 2500 interacting particles in two dimensions, so you can explore phases of matter, emergent behavior, irreversibility, and thermal effects at the nanoscale.|
|Fluid Dynamics simulates a two-dimensional fluid in a wind-tunnel arrangement using the lattice-Boltzmann algorithm, demonstrating vortex shedding and forces on barriers.|
|Ising Model simulates a magnet in two dimensions using the Metropolis algorithm, with the ability to rescale the lattice at any time.|
|Electric Potentials and Fields (by WSU student Nathaniel Klemm) solves Laplace’s equation for the electrostatic potential around an arbitrary arrangment of user-drawn conductors.|
|Wave Builder is a computer-aided exploration of building arbitrary wave shapes out of sine waves or other simple basis functions.|
|Quantum wavefunction simulations showing time evolution in one dimension:
Sinusoidal Wave Square Well Harmonic Oscillator Wavepackets Barrier Scattering
|Quantum Bound States in Two Dimensions displays two-dimensional wavefunctions for a variety of user-adjustable potentials.|
|Entanglement in a Box displays the entangled low-energy wavefunctions for two interacting particles in a one-dimensional box.|
|Quantum Scattering in Two Dimensions simulates scattering of a wavepacket from a variety of two-dimensional barriers.|
|Colliding Wavepackets simulates a two-particle quantum collision, showing how independent particles become entangled when they interact.|
|Quantum Matrix Diagonalization Visualized (by WSU student Kevin Randles) helps you find bound states in one dimension by rotating the basis states until the Hamiltonian matrix is diagonal.|
|Spins Laboratory, a simulation of linked Stern-Gerlach devices:
Two-state (spin-1/2) version Three-state (spin-1) version
|Two-Source Interference is a simple animation of wave propagation from a pair of identical sources with variable separation.|
|Chaotic Pendulum is a simple simulation of a damped, driven pendulum, with a phase space plot.|

|U.S. Power Plants, 2018 is an interactive map that shows where our electricity comes from.|
Software for older platforms is now listed on a separate page.
I also recommend the amazing software collection at Falstad.com, and the cartooney but often useful PhET physics simulations.
