Noah Raford is an urban planner and the Director of Space Syntax Limited in North America. He is currently pursuing his PhD at the Massachusetts Institute of Technology (MIT) and recently gave a talk at the London School of Economics titled "Collapse Dynamics: Phase Transitions in Complex Social Systems." This show discusses how complex social systems become inflexible, leading to their collapse, and what strategies individuals aware of collapse might use to cope. Noah's website is Space Syntax.com. The video and slide show of Noah's talk can be found here, and a discussion about the talk on the Oil Drum is here.
