Did You Know?

Since the pendulum's length was constant, from (1) the ratio of the gravitational accelerations was equal to the square root of the ratio of the periods, and no precision length measurements were necessary.

This principle, called Schuler tuning, is used in inertial guidance systems in ships and aircraft that operate on the surface of the Earth.

Kater's measurement was used as Britain's official standard of length (see.

The timekeeping accuracy of the pendulum was exceeded by the quartz crystal oscillator, invented in 1921, and quartz clocks, invented in 1927, replaced pendulum clocks as the world's best timekeepers, although the French Time Service continued using pendulum clocks in their official time standard ensemble until 1954.

This took much of the appeal from the concept, and efforts to adopt pendulum standards were abandoned.One of the first to suggest defining length with a pendulum was Flemish scientist Isaac Beeckman.

A plan for a complete system of units based on the pendulum was advanced in 1675 by Italian polymath Tito Livio Burratini.
