look up any word, like bukkake:
Concept used in the work of Michel Foucault, to denote the interchangeability and mutual supportiveness of power and knowledge. Because he thought a regime of power always constructs forms of knowledge and a regime of knowledge always institutes a regime of power, he fused the two words into a single concept.

For example, prisons are an example of a regime of power/knowledge: the observation of prisoners and the recording of different categories of criminality are in many ways identical with the process of incarceration itself, as a system of control of people's bodies and of physical spaces.
Mental asylums, schools, armies, etc. are all different examples of regimes of power/knowledge. The way in which people are recorded as elements in these discourses is connected to their subordination to or complicity in particular relations of power.
