'Pataphysics (French: 'Pataphysique), a term coined by French writer Alfred Jarry (1873 – 1907), is a philosophy or pseudophilosophy dedicated to studying what lies beyond the realm of metaphysics. It is a parody of the theory and methods of modern science and is often expressed in nonsensical language.

In the 1960s 'pataphysics was used as a conceptual principle within various fine art forms, especially pop art and popular culture. Actual works within the 'pataphysical tradition tend to focus on the processes of their creation, and elements of chance or arbitrary choices are frequently key in those processes. Select pieces from Marcel Duchamp and John Cage characterize this. At around this time, Asger Jorn, a 'pataphysician and members of the Situationist International, referred to 'pataphysics as a new religion. Rube Goldberg and Heath Robinson were artists who contrived machines of a 'pataphysical bent.
