This lecture course researches global infrastructure space as a medium of polity. More than networks of pipes and wires under the ground, this infrastructure space is a visible, enveloping urban medium filled with repeatable spatial formulas and spatial products. Lectures visit the networks of trade, communication, tourism, labor, air, rail, highway, oil, hydrology, finance, standard making, and activism. Case studies travel around the world to, for instance, free trade zones in Dubai, IT campuses in South Asia, high-speed rail in Saudi Arabia, cable/satellite networks in Africa, highways in India, a resort in the DPRK, golf courses in China, ISO standards, and automated ports. More than a survey of physical networks and shared protocols, the course also repositions spatial variables in global governance. Infrastructure space may constitute a de facto parliament of decision-making—an intensely spatial extrastatecraft that often spins around irrational desires. Each week, readings, with both evidence and discursive commentary, accompany two lectures and a discussion section. A short midterm paper establishes each student’s research question for the term. A final paper completes the requirements of the course.
