Physics

Doppler Effect

Move a sound source and an observer, change the speed of sound and the wind, and watch the observed frequency shift — all the way to a supersonic Mach cone.

Middle school+ 2D

PhysicsEngineering

Wave Propagation Through Materials

Send a sound or electromagnetic wave into a slab of water, glass, concrete, metal or lead and see how much is reflected, absorbed and transmitted.

High school+ 2D

PhysicsChemistry

3D Brillouin Zone & Bragg Diffraction

Build reciprocal lattices, explore 3D Brillouin zones and simulate X-ray diffraction with Bragg’s law, structure factors, band structures and peak fitting.

University 3D

Learn by changing things

Every simulation is a small laboratory. Move a slider, drag an object, switch a material — and watch the science respond instantly.

Explore
Open a simulation in your browser. Nothing to install, nothing to sign up for.
Experiment
Change speeds, frequencies and materials. Ask “what if?” and test it.
Understand
Connect what you see to the equations behind it, with live graphs and formulas.

About us
