Mexican waves in an excitable medium.

Area of Science:

• Collective human behavior
• Complex systems modeling
• Social dynamics

Background:

• The Mexican wave (La Ola) is a famous spectator phenomenon originating from the 1986 World Cup.
• It involves synchronized, sequential activation of spectators in a stadium.
• Understanding such collective behavior is challenging.

Purpose of the Study:

• To interpret and quantify the collective human behavior of the Mexican wave.
• To apply models from excitable media to understand crowd dynamics.
• To investigate methods for stimulating and potentially controlling crowd waves.

Main Methods:

• Utilized a variant of models originally developed for excitable media (e.g., cardiac tissue).
• Modeled the reaction of spectators to attempts to initiate the wave.
• Quantified the dynamics of wave propagation through the crowd.

Main Results:

• Successfully modeled the Mexican wave using principles of excitable media.
• Identified key factors and mechanisms that stimulate the initiation and propagation of the wave.
• Demonstrated the feasibility of predicting crowd responses to wave-triggering attempts.

Conclusions:

• The Mexican wave can be effectively understood and modeled using excitable media theory.
• This modeling approach provides insights into the stimulation of collective human behavior.
• Findings may be applicable to managing and controlling events involving large, excited groups.
