Perpetual motion is the motion of bodies that continues forever in an unperturbed system. A perpetual motion machine is a hypothetical machine that can do work indefinitely without an external energy source. This kind of machine is impossible, since its existence would violate the first and/or second laws of thermodynamics. [2] [3] [4] [5]
In 1861, he commented on the subject in his book that "The subject of Perpetual Motion opposes paradox to paradox." [26] His book Perpetuum mobile; or, Search for self-motive power, published in 1861, examined many attempts at creating such a device, and has since been cited by other science writers on the subject. Dircks summarised the ongoing ...
As a distinct composition, perpetuum mobile can be defined as one in which part or most of the piece is intended to be repeated an often unspecified number of times, without the "motion" of the melody being halted when a repeat begins.
An engraving of Robert Fludd's 1618 "water screw" perpetual motion machine. The history of perpetual motion machines dates at least back to the Middle Ages. For millennia, it was not clear whether perpetual motion devices were possible or not, but modern theories of thermodynamics have shown that they are impossible. Despite this, many attempts ...
Example of a magnet motor design. The predominantly attracting orientation of the magnets apparently leads to a perpetual rotary motion. A hypothetical magnet motor works with permanent magnets in stator and rotor. By a special arrangement of the attracting and repelling poles, a rotational movement of the rotor is supposedly permanently ...

The King James clock was known as the Eltham Perpetuum, and was famous throughout Europe. It is mentioned in two works of Ben Jonson. Clocks powered by atmospheric pressure and temperature changes were subsequently developed by Pierre de Rivaz in 1740, [3] and by James Cox and John Joseph Merlin (Cox's timepiece) in the 1760s.
Signs of Life is the fourth studio album by the Penguin Cafe Orchestra.It was recorded at the Penguin Cafe between 1985 and 1987 and released in March 1987. It includes "Perpetuum Mobile", one of their most famous pieces.
