Simulations

3D Fluid Simulator Real 3D smoke you can rotate: rising plumes, smoke rings that collide, wind past a sphere. Navier–Stokes solved live in your browser.	Atomic Clock Simulator See how atoms keep time: lock a quartz clock to caesium, tune a fountain, race clocks against each other and compare their stability.
Black Hole Simulator Bend light around a black hole, find its shadow and photon sphere, follow orbits that precess or plunge, and see a ray-traced picture with a glowing disk.	Buddhabrot Explorer Watch the Buddhabrot fill in live: millions of random Mandelbrot orbits piled into a glowing figure. Try the three-colour Nebulabrot and the Anti-Buddhabrot.
Caesium Fountain Clock A 3D fountain atomic clock: cool a ball of atoms, toss it up through the microwave cavity and see why throwing higher stops helping.	Double Pendulum Drag two swinging arms into place and watch chaos: a fan of copies that drift apart, how fast errors grow, and a fractal map of how long each start takes to flip.
Electromagnetic Fields Simulator Place charges and wires and see field lines, Gauss's law and Ampère's law, steer a particle through E and B fields, and watch Maxwell's equations make waves reflect, refract and diffract.	Faster-Than-Light Shadow Simulator Swing a torch beam or move a finger and watch the spot or shadow on the Moon outrun light, with true light-travel delay. See why no message rides on it.
Fluid Simulator Navier–Stokes in 2D, live: vortex streets behind a cylinder, hot plumes, swirling layers. Stir it, block it, change the Reynolds number.	Ground Rod & Earthing Simulator Find a ground rod's resistance for your soil, see why a rod doesn't trip a breaker, model lightning step voltage and static discharge, and read the grounding rules for your region.
Julia Set Explorer Drag a point on a map of the Mandelbrot set and watch its Julia set change live. Walk c around the cardioid, zoom and save pictures.	Letter and Digit Recognition Train a small network to read digits and letters, draw a character and see what it thinks, test it on unseen fonts, and teach it your handwriting.

Magnetic Isopotentials Drag and turn bar magnets and see their flux lines and magnetic isopotentials at once, with compasses, horseshoe and Halbach examples.
Mandelbrot Explorer Zoom into the Mandelbrot set, see the Julia set of any point, trace orbits and try the Burning Ship, Tricorn and Multibrot fractals.
