Joseph A. Burton Forum Award Talk: New Terrorism Reveals New Physics*

In this talk, I will try to convince you that buried in arguably the most urgent challenge facing society, i.e. global terrorism, lies a wealth of interesting physics related to many-body out-of-equilibrium systems, complex dynamical networks, critical phenomena, kinetic theory, and even Green's Functions and Feynman diagrams [1-10]. Moreover there now exist detailed spatiotemporal datasets on global violent events which back up these claims. During the talk, I will try to emphasize the point that this is not just about providing something new for Physics, but rather that Physics is uniquely positioned to offer key insights into this important ‘many-person problem’ in a way that the traditional disciplines associated with analyzing terrorism can never do.
