Peter K. Haff is professor emeritus of Geology in the Nicholas School of the Environment at Duke University, North Carolina. His research focuses on the physical properties of the technosphere (human networks, human capital and technology) that do not depend on the details of their components. These non-anthropocentric perspectives make it possible to re-adjust the view of our position in the world as humans by focusing attention from one individual human purpose toward the co-determinations that bind us to the technosphere.
