The Physics of Mosh Pits

Großartig: Wissenschaftler haben das Verhalten von Metalheads in Moshpits untersucht und festgestellt, dass sich Moshpits wie Gase verhalten. Dazu gibt's 'ne komplette Studie als PDF mit so tollen Sätzen wie: „moshers are self-propelled agents that experience dissipative collisions“, eine JavaScript-Simulation von Moshpits, eine Website zur Untersuchung und natürlich eine Reihe von Artikeln dazu, einer schöner als der andere, hier ein Snip vom New Scientist:

Research into how humans behave in crowds had mostly been limited to fairly organised situations, like pedestrians forming lanes when walking on the street. But when Jesse Silverberg, a graduate student at Cornell University in Ithaca, New York, took his girlfriend to her first heavy metal concert a few years ago, he witnessed a different and surprising form of crowd behaviour.

"I didn't want to put her in harm's way, so we stood off to the side," he says. "I'm usually in the mosh pit, but for the first time I was off to the side and watching. I was amazed at what I saw."

Metal fans' favoured dance style is called moshing and mostly involves bodies slamming into each other. Silverberg wondered if the mathematical laws that describe group behaviour in flocks of birds or schools of fish could apply to moshers as well. Together with another grad student and two physics professors at Cornell, he pulled videos of mosh pits off YouTube and used software developed for analysing particles in a fluid to track the moshers' motions. They found that the dancers' speeds had the same statistical distribution as the speeds of particles in a gas. Such particles move around freely, interacting only when they bounce off one another.
