Physics Explained Visually

Physics is about how things move, so it should be explained with motion. Turn a knob, watch the effect, then see the equation that predicted it.

Every animation here is computed, not illustrated, so pendulums swing and waves travel the way the physics says.

Build the Navier–Stokes equations from conservation laws and see how pressure, viscosity and acceleration describe the motion of a fluid.

Watch two nearly identical double pendulums rapidly diverge and discover why tiny differences make chaotic systems difficult to predict.

Visualize ripples in spacetime, plus and cross polarizations, and the laser interferometers used to detect extraordinarily small changes in distance.
