This a rare opportunity to see Manuel Castells speak in London. I have a feeling this will be seriously well-attended and may be shifted to the Bank of Ideas building on Sun Street. Keep an eye on the Occupylsx site for details. Castells is a Spanish urban sociologist who was the first to systematically map the dominant characteristics of what he called The Information Society. His work has been incredibly influential in analyzing the ways in which information networks shape the society as a whole. He identified a number of key characteristics of the network society, such as the space of flows, timeless time and real virtuality.
