The hidden geometry of complex, network-driven contagion phenomena
The video clip below illustrates a simulated global epidemic that spreads on the worldwide air-transportation network with an initial outbreak location in Atlanta, USA. In the right panel, the conventional geographic view, the pattern is complex. The left panel depicts the same simulation from the perspective of the outbreak location (Atlanta) and the radial distance is an effective distance compute from traffic flows in the underlying network. In this view, the pattern is regular, concentric and can be understood in terms of simple reaction-diffusion equations. The science of this is described in detail here.
