The Ripple Tank applet demonstrates wave motion, interference, diffraction, refraction, and the Doppler effect in a simple 2‑D experiment. The 2‑D Waves and 3‑D Waves applets extend the simulation to planar and volumetric media, showing coupled oscillators, dispersion, and acoustic string models for longitudinal waves.

Electrostatic and magnetostatic fields are visualized in 2‑D and 3‑D applets, also displaying Gauss’s law and magnetic field lines. The Electrodynamics series demonstrates electromagnetic radiation, induction, and TE/TM modes. An ornate circuit simulator and filter applets let users build and listen to electronic circuits.

The Quantum Mechanics Hydrogen Atom applet reveals orbital shapes, while 1‑D and 2‑D crystal, harmonic oscillator, and rigid rotator models explore periodic potentials and rotational motion. Vector calculus is explored through 2‑D and 3‑D field applets, including Lorenz and Rossler attractors.

Thermodynamics is covered by a gas‑molecule simulation, Carnot cycle, and heat‑engine examples. Mechanics applets cover harmonic oscillators, Coriolis forces, and orbital rendezvous. An ODE solver, Euler’s series, and discrete Fourier transform tool round out the collection.
