Pataphysics is a term coined by the French writer Alfred Jarry, a philosophy 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. A practitioner of pataphysics is a pataphysician or a pataphysicist. Pataphysic (contraction of the greek "epì tà metà tà phusiká") means "what is close of what is after physics".
