Fibonacci Sequence

The Fibonacci sequence visualized — watch 1, 1, 2, 3, 5, 8, 13, 21 build into the golden spiral. See how the ratio converges to phi (1.618).

AC vs DC Current

3D comparison. DC: electrons flow one direction steadily (battery). AC: electrons oscillate back and forth 60 times per second (wall outlet). Show waveforms: flat line vs sine wave.

Angular Momentum

3D ice skater spinning. Arms out: slow spin. Pull arms in: spin faster. Angular momentum L=Iω stays constant — decrease moment of inertia, increase angular velocity.
