Answer:
it about Michel examining the relationship of power to knowledge and to the body as having no substantial content, and OS meaning nothing.
he argues that institutions such as the army,the factory and the school, all discipline the bodies of their subjects through surveillance techniques, both real and perceived. He maps the emergence of a disciplinary society and its new expression of power.
He uses the model of Jeremy Bentham's Panopticon to illustrate the structure of power through an architecture designed for surveillance. (The design of Bentham's prison allows for the invisible surveillance of a large number of prisoners by a small number of guards, eventually resulting in the embodiment of surveillance by the prisoners, making the actual guards obsolete. The prison is a tool of knowledge for the institutional formation of subjects, thus power and knowledge are inextricably linked.)
