Pendulum Clock

timekeeping · physics · history

Invented in 1656. Christiaan Huygens created the pendulum clock, inspired by watching Galileo's ideas about swinging objects. It became the world's most accurate clock for nearly 300 years.

Nature's rhythm works. The pendulum swings back and forth at the same speed every time, like a natural metronome. The length of the pendulum determines exactly how fast it swings.

Kept society running. During the Industrial Revolution, pendulum clocks in factories, offices, and train stations told everyone when to work and when trains would arrive. They helped make the modern world possible.

Super precise timing. Pendulum clocks were so accurate that they became the official time standards for entire cities and countries. Nothing else could measure time as well until electric clocks arrived.

Beautiful and timeless. Today, people keep antique pendulum clocks not because they need to tell time, but because they're gorgeous to look at and remind us of history.
