A pendulum clock is a clock that uses a pendulum, a swinging weight, as its timekeeping element. From its invention in 1656 by Christiaan Huygens until the 1930s, the pendulum clock was the world's ...

In 1656, Christian Huygens, a Dutch scientist, made the first pendulum clock, regulated by a mechanism with a "natural" period of oscillation. Although Galileo Galilei, sometimes credited with inventing the pendulum, studied its motion as early as ... Timeline of Atomic Clock History - Cesium Fountain Atomic Clock...

He investigated the motion of a pendulum during intervals of time. And he considered the relationship between time for pendulum motion and time for free fall motion. Our present description for a small arc of pendulum motion is:

In order to determine the exact period of the pendulum, one must count the number of oscillations within a specified time. Galileo and his students measured the number of oscillations through which a pendulum passes in an entire day, in order to determine its precise period.

Something hanging from a fixed point which, when pulled back and released, is free to swing down by force of gravity and then out and up because of its inertia. ... Inertia: means that bodies in motion, will stay in motion; bodies at rest, will stay at rest, unless acted on by an outside force ... What's a pendulum anyway?

Parkinson's thesis is that the whole of civilized history can be reduced to the confrontation of the East and West, with "alternating phases of Oriental and Western ascendancy." The West set the pendulum in motion with the capture of Troy in about 1250 B.C., which launched the Greeks' thrust into Asia Minor.

In physics, he discovered the laws of falling bodies and the motions of projectiles. In the history of culture, Galileo stands as a symbol of the battle against authority for freedom of inquiry.
