Move generators, repartition the nearest territories, and try Lloyd relaxation.

Dive into Mandelbrot and Julia boundaries to uncover structure inside iteration.

Analyze interference with a complex field, oscilloscope, phasors, and directivity.

Inject dye and momentum, then observe vortices shaped by viscosity and diffusion.

Derive VTH, EOT, DIBL, and I–V behavior from geometry, dielectric, and doping.

Compare CCD and DLS while reading Jacobians, singularities, and convergence.

Design optical paths and measure refraction, spectral power, and system loss.

Break your drawing into rotating circles and watch frequencies rebuild it.

Stabilize motors, vehicles, pendulums, and drones with three PID knobs.

Compare wheel-lock control and stopping distance on dry, wet, and icy roads.

See how predictive steering dynamics smooth high-speed path tracking.

Tune the autonomous-agent simulation that lives behind this site.

Flocking emerges from three rules — and flees from your cursor hawk.

Watch A*, Dijkstra, Greedy, and DFS solve the same maze differently.

Merge bodies into planets, stars, red giants, and black holes.

From a two-line rule to glider guns — Conway's cellular automaton.
