Physics Simulations

	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.

	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.

	Newton’s Cannon animates Isaac Newton’s famous thought experiment of firing projectiles horizontally from a high mountaintop.
