Social behaviour: Mexican waves in an excitable medium

  author={Ill{\'e}s J. Farkas and Dirk Helbing and Tam{\'a}s Vicsek},
The Mexican wave, or La Ola, which rose to fame during the 1986 World Cup in Mexico, surges through the rows of spectators in a stadium as those in one section leap to their feet with their arms up, and then sit down again as the next section rises to repeat the motion. To interpret and quantify this collective human behaviour, we have used a variant of models that were originally developed to describe excitable media such as cardiac tissue. Modelling the reaction of the crowd to attempts to… 

Human waves in stadiums

Variants of models originally developed for the description of excitable media are used to demonstrate that this collective human behaviour can be quantitatively interpreted by methods of statistical physics.

Is the Mexican wave really a ripple of excitation

have seen more examples of that phenomenon of mass audience participation in stadia — first brought to the world's attention during the 1986 World Cup in Mexico — the Mexican Wave. In the pages of

Chemical Excitable Medium in Barcelona Street Network as a Method for Panicked Crowds Behavior Analysis

It is demonstrated that with decreasing excitability, the spanning of the street networks by an excitation wavefront shows evidence of pruning toward wider and ballistically plausible pathways.

Collective motion of humans in mosh and circle pits at heavy metal concerts.

This work uses videos publicly available online to study the highly energized collective motion of attendees at heavy metal concerts, and finds these extreme social gatherings generate similarly extreme behaviors: a disordered gaslike state called a mosh pit and an ordered vortexlike statecalled a circle pit.

Speeding Up Social Waves. Propagation Mechanisms of Shimmering in Giant Honeybees

It is discussed that the saltatoric process could enable the bees to instantly recruit larger cohorts to participate in shimmering and to respond rapidly to changes in flight direction of preying wasps.

Initiation and spread of escape waves within animal groups

A simulation model is used to demonstrate that changes in the direction and speed by a small percentage of individuals that detect the danger initiate an escape wave, and this mechanism can, through local interactions alone, produce arbitrarily large escape waves.

Complex social waves of giant honeybees provoked by a dummy wasp support the special-agent hypothesis

A nest that originated by amalgamation of two previously separated nests and stimulated waves by a dummy wasp moved on a miniature cable car is used to illustrate the plausibility of the special-agent hypothesis also for complex shimmering processes.


Using the example of the Mexican Wave, new approaches based on cellular automata and agent-based models are discussed and how these may be related to classical continuum physics.



Spatial Patterns for Discrete Models of Diffusion in Excitable Media

In a spatially homogeneous environment an excitable media is characterized by a globally stable equilibrium state, and also by a threshold mechanism which produces a large amplitude response to a

Spiral wave generation in heterogeneous excitable media.

As the coupling in a heterogeneous excitable medium is reduced, three different types of behavior are encountered: plane waves propagate without breaking up, plane waves break up into spiral waves,
