Perpetual Motion Chronology

A time table of important events, inventions and discoveries around the history of perpetual motion.

 500 v.Chr.  The greek philosopher Anaxagoras states "nothing can emerge from nothing and nothing can be annihilated."
 ca.300 v.Chr.  Aristoteles lays the foundation of the horror vacui and thus (unintendedly) prepares scientific stagnation and ignorance for 2000 years.
ca. 1100  The indian astronomer and mathematician Bhaskara describes a perpetuum mobile made of a wheel with containers attached to its rim, partly filled with mercury.
ca.1250  Thoma Aquino proves the Pope's infallability and thus finishes the effort to make the aristotelian philosophy a dogma.
1235  The french master-builder Villard de Honnecourt describes an overbalanced wheel with 7 hammers attached to its rim.
1269  Pierre de Maricourt describes a hypothetic perpetual motion machine which uses the powers of the magnetic lodestone.
ca.1325  William Ockam states the principle: Entia non sunt multiplicanda praeter necessitatem "We don't make more hypothesis and assumptions than absolutely necessary." This principle became known as Ockham's Razor.
ca.1480  Francisco di Giorgio describes in his Trattato I & II several dry water mills, also being called recirculation mills.
ca.1490(?)  Leonardo da Vinci draws a plan of the momentums acting on a classical overbalanced whell und thus proves the impossibility of the arabian perpetual motion machine.
1480  Leonardo da Vinci makes several sketches of PMMs bases on archimedian screws and overbalanced wheels. At the same time, he notes that the seeker for perpetual motion shall join the gold-makers.
1562  The Jesuit Johannes Taisnierus (Johann Tausner) describes a magnetic PMM which consits of a ramp, a magnetic lodestone and an iron ball.
1586  Simon Stevin proves by the aid of a diagram the impossibility of a PMM based on a ramp and an endless chain.
