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.
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] These laws of thermodynamics apply regardless of the size of the system.
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 have been made to construct such machines, continuing into modern times.
Cornelis Jacobszoon Drebbel[1] (Dutch pronunciation: [kɔrˈneːlɪ ˈɕaːkɔpsoːn ˈdrɛbəl]; [a] 1572 – 7 November 1633) was a Dutch engineer and inventor. He was the builder of the first operational submarine in 1620 and an innovator who contributed to the development of measurement and control systems, optics and chemistry.
Bhāskara's wheel. Bhāskara's wheel was a hypothetical perpetual-motion machine design created around 1150 CE by the Indian mathematician Bhāskara II. The wheel consisted of curved or tilted spokes partially filled with mercury. [1] Once in motion, the mercury would flow from one side of the spoke to another, thus forcing the wheel to ...
"Mouvement" is the most abstract designation of the pieces. It is a perpetuum mobile, meaning that it is built around a continuous stream of notes. [6] "Cloches à travers les feuilles" was inspired by the bells in the church steeple in the village of Rahon in Jura, France. [7]
The Economist magazine has used "Perpetuum Mobile" in its weekly podcasts. The Australian ABC Radio National weekly broadcast of The Music Show uses "Perpetuum Mobile" as its theme music. "Scherzo and Trio" is the theme music for BBC Radio 4's Round Britain Quiz. "Pythagoras's Trousers" was the theme music for CBC Radio's Basic Black.
A new commercial album was made available later in the year, [13] the first release since 2004's Perpetuum Mobile. The new album, Alles wieder offen ("All open again"), was released in 2007 [4] without the backing of a label, a move the band had intended to make with Perpetuum Mobile. Fans who were part of the paid EN community at neubauten.org ...
