AC Circuits: Impedance and Phase Shift
Compare R, RC, RL, and RLC circuits, phase shift, impedance, and resonance.
Discover Neptune: how mathematics found an unseen planet
Investigate the perturbation of Uranus and tune Planet X to recreate the mathematical discovery of Neptune.
All Simulations
Apollo Parachute Descent
Configure Apollo’s parachute descent and see how deployment timing and Euler’s method affect a safe splashdown.
Apollo: Re-entry
Test Apollo return trajectories, hit the safe corridor, and see why mathematics and computation mattered for bringing the capsule home.
