The Origins of Pendulum Clocks

By: Jim Slate | 2010-04-01 | Interior Design
Pendulum clocks are a type of clock that works by suspending a mechanical body so that it swings back and forth to tell the time. Pendulum clocks as we know today were perfected in 1656 and they represented man's first invention at accurately telling the time. The clock has a face, a weight, a keyhole and the pendulum. The swing of the pendulum controls hidden gears inside the clock to move the hands on the face of the clock that resultantly tell the time in hours and minutes. read more

Do you know the theory of watches' PENDULUMS?

By: Fayfairy | 2010-10-19 | Jewelry
If so, it is plain that this knowledge had itself languished and died, before the making of what has long been called Galileo's discovery in the church at Florence, that a chandelier, and therefore any other pendulum, vibrated different arcs in the same time, provided they were none of them large ones. When we consider the vast number of pendulums of various kinds that there are swinging about the world, it certainly is difficult to imagine that nobody ever made that observation before the sixte read more

Pendulum Wall Clocks Adding New Look To Clocks Of Today

By: stelensmith | 2011-01-22 | Shopping
Pendulum wall clocks are wall clocks that use a swinging weight, called a Pendulum, to help keep time. This method was developed in the middle of the seventeenth century by Christian Huygens, and was the most accurate method of keeping time for almost four hundred years. read more

How the Democratic Pendulum is Working in the USA

By: Ernest Ionescu | 2010-03-30 | Politics
The American democracy works like a mechanical pendulum. There is an analogy where the load is supposed to represent the democracy in unstable balance around an equilibrium point. There are swings from left to right and right to left in between two limits. The whole idea is that the democracy is the perfect only for a fraction of time when the pendulum has the maximum speed. With other words the democracy is hard to achieve and hard to keep. read more
