Huygens' Pendulum

Huygens' pendulum demonstrates how two pendulums hanging close together can synchronize their swinging over time, even if started at different times or with different amplitudes. This occurs because the pendulums exchange energy through the shared support, gradually adjusting their swings until they move in unison. This phenomenon reveals how coupled systems naturally seek synchronization, and it was key in understanding resonance and vibrations in various mechanical and natural systems. In essence, Huygens' pendulum beautifully illustrates the tendency of interconnected oscillators to align their motion through mutual influence.
