-'''Arborescent''' is a term coined by the French thinkers [[Deleuze]] and [[Guattari]] to characterize thinking marked by insistence on [[totality|totalizing]] principles, [[binarism]] and [[dualism]]. The terms, first used in ''[[A Thousand Plateaus]]'' (1980) where it was opposed to the [[rhizome (metaphor)|rhizome]], comes from the way [[genealogy tree]]s are drawn: unidirectional [[progress (philosophy)|progress]], with no possible retroactivity and continuous binary cuts (thus enforcing a dualist metaphysical conception, criticized by Deleuze). Rhizomes, on the contrary, mark an horizontal and non-hierarchical conception, where anything may be linked to anything else, with no respect whatsoever for specific [[species]]: rhizomes are [[heterogeneity|heterogeneous]] links between things that have nothing to do between themselves (for example, Deleuze and Guattari linked together [[desire]] and [[machine]]s to create the - most surprising - concept of [[desiring-production|desiring machine]]s). [[Horizontal gene transfer]] is also an example of rhizomes, opposed to the arborescent [[evolutionism]] theory. Deleuze also criticizes the [[Chomsky hierarchy]] of [[formal languages]], which he considers a perfect example of arborescent dualistic theory.+The term is often used in a [[science|scientific]] (such as a kind of [[catalyst]]), [[mathematics|mathematical]], [[sociology|sociological]] or [[statistics|statistical]] context.

Homogeneity and heterogeneity are concepts relating to the uniformity in a substance. A material that is homogeneous is uniform in composition or character; one that is heterogeneous is distinctly nonuniform in one of these qualities.

The term is often used in a scientific (such as a kind of catalyst), mathematical, sociological or statistical context.

Homogeneity

  1. similar, or the same as something else
  2. having the same composition throughout; uniform

Heterogeneity

  1. Diversity
  2. A composition of diverse parts
