Pushout and Pullback: The Perpetual Recurrence of Opposits
This work made as a responce to the a painting by Marcel Duchamp (1911) at Tate Gallery, London, also known as the Coffee Grinder.
This is based on a mathematical concept called Category Theory: Pushout and Pullback.
A pushout (also called a fibered coproduct or fibered sum or cartesian square or amalgamated sum) is the colimit of a diagram consisting of two morphisms f : Z → X and g : Z → Y with a common domain. The pushout consists of an object P along with two morphisms X → P and Y→ P that complete a commutative square with the two given morphisms f and g. In fact, the defining universal property of the pushout essentially says that the pushout is the "most general" way to complete this commutative square.
A pullback is, a function f of a variable y, where y itself is a function of another variable x, may be written as a function of x. This is the pullback of f by the function y. it is the limit of a diagram consisting of two morphisms f : X → Z and g : Y → Z with a common codomain.
