Heavy Metal and Emergent Behavior
You may think that moshing and disordered 2D gases don't have much in common but Jesse Silverberg of Cornell University contends otherwise. He says that mosh pits act just like disordered gases and people in circle pits act in an ordered vortex-like state. From the article: "Silverberg and co gathered their data by examining videos of mosh pits on You Tube... These crowds contain anything from 100 to 100,000 people. After correcting for camera shake and distortions in perspective, they used particle image velicometry techniques to measure the collective motion of moshers. What they discovered was that the speed distribution of moshers closely matches that of molecules in a 2D gas at equilibrium."
A large group of people in a circle pit resembles a bunch of molecules circling? I'll be damned.
A sure candidate.
My experience with smaller mosh pits (guess: up to 50 headbangers) indicates a different pattern, more like a sloshing wave. Most people move in one direction until they get near the edge and then go back.
Is this a size thing? The mosh pits analyzed in this story are bigger. Changes that the behavior?
Well, I might have a way, but it only works on a semi spherical planet in a vacuum.
Consider a spherical heavy metal fan..

There is always order in chaos!
You might be interested in new kind of science, where Stephen Wolfram argues that fluid (and gas) movement is a general pehonomena, which can be replicated using only very basic rules. And therefore must occur in very broad range of materials, regardless of their underlying precise rules. And he is right. I am no surprised that this also applies to heavy metal crowds.

I for one welcome our heavy metal overlords, may their head-banging always strike true
"the speed distribution of moshers closely matches that of molecules in a 2D gas at equilibrium"
I knew all along that metal fans were all airheads, now proven by science!
It also explains Mathcore.
How music fans act as molecules.
Headbangers + applied energy (awesome riffs & volume) fill a volume as individual particles, do not form products, expand the volume of their "container" as pressure increases and dissipate when applied energy source is removed.
Country line dancers (extremely soluble in ethanol) + applied energy (twangy vocals and guitars + ethanol) enter solution as a binary compound, form complex molecules and then dissipate as binary compounds (not necessarily with the original conjugate species). However, once the molarity of ethanol diminishes, these binary compounds dissolve and seek higher concentrations of ethanol often showing an affinity for elements with a higher electronegativity (redneck factor). It must be noted that country line dancers become highly volatile for no known reason(s) regardless of the concentration of the ethanol solution.
If you argue with me, how about we turn this into a peer reviewed article right here on slashdot!
This really flows well with the book I'm reading at the moment, The God Problem by Howard Bloom. This is an example of translation causing transformation, the movement of the gas molecules is a recruitment strategy that is dominate enough to cross between different, err things? The same pattern in the gas create a social/group activity when translated to humans. One of the examples given in the book outlines how bacterial colonies in Petri dishes spread out in fractal patterns just like those found in rocks.
It's a fairly stretched out book, I originally started reading it for his theory of the shape of our universe, a bagel. In theory it replaces dark energy with gravity to explain the accelerated burst and subsequent slow down experienced by the early universe as well as the missing anti-matter. 250 pages in and it's covered the history of science while explaining how we miss what's right under our nose, such as the Egyptians making perfect right angles using the golden ratio and never discovering the concept of angles. Highly recommend it!
The particles are Sentient, AND listen to Metal!
I can only wonder if the stripedkau is also a spherical cow? How now, spherical cow,
physical perfection, here and now!
Wow, rely on stereotypes much? Not everyone who is in to Metal is empty headed. Some people actually just prefer the sound of grinding guitar and blast beats drums. Also, Anti-Intellectual? How exactly does musical preference infer that kind of stance?
As in "Chris Cornell"?
Ditto. I was a long haired head banger back in the late 80's. Went on to get my MSEE. I still bang on my drums to Maiden, King Diamond, Kreator, etc..
And math-metal and prog-metal are quite interesting and complex. The bands producing that stuff are quite creative. There are also a lot of excellent musicians in metal.
Remember that scene from the first Sherlock Holmes movie where he has those flies in a glass tube and he's plucking a violin?
Perhaps Slayer is a more pure example of creating order out of chaos: http://www.youtube.com/watch?v=9yMwJ79IeHk
Hell, "The Particles" ought to be the name of a heavy metal band.
This will be my PhD
Not everyone who is in to Metal is empty headed.
True, many smart people have bad taste.
Give me Classic Slashdot or give me death!
s/Mosh Pit/Circle Pit/g;
They're different things. A mosh pit is where folk charge from the edge to the centre, and is pretty disorganised. Typically you'll find this with Death Metal, Speed Metal, and other very fast beat genres where there is no discernable difference between, say, verse and chorus. Circle Pits are the phenomenom being investigated here, where they start moving in a fairly ordered vortex around the centre, before moving into the centre when the band "drops the bass", then moves back to the circle when there's a "lull" (comparitively).
Hope this helps, science types.
Finally had enough. Come see us over at https://soylentnews.org/
Instead you clearly have a very simplistic view of fluid flow. One very simple laminar flow experiment I saw in the 1980s needed a pipe the length of a reasonable sized University building to ensure that there wasn't turbulent flow at the outlet.
Where pray-tell did they find a 100,000 person mosh pit? Most pits I've seen have been more like 1-100 people.
Then my metal comrades and I whipped up some awesome science last night at a Turisas show. I wonder if I can get a grant to incite mosh pits for the purpose of studying...
I can see Charlie Epps explaining how they'll model the mosh pit as a disordered gas, with the in it behaving in an ordered vortex-like state, in order to find the location of the killer!
Smart people know there is no evidence of such things as "bad" or "good" tastes, just different tastes; such labels are mere social pretensions created by those whose insecurity is worn on their shirt sleeves. Right next to the snot stains.
That typo had me puzzled for a bit.
Disco still sucks.
Huh?
And this reminds me of the Crowd Quake. Most crowd disasters are not due to Stampedes, where mass panic breaks out and people rush headlong into a choke point and get crushed. Researchers looking into the Love Parade Disaster discovered a hitherto unrecognised crowd dynamical process that can kill people in large crows - the Crowd Quake.
In normal crowds there's personal space between people, room to breath and move even a little bit. This personal space accommodates and cushions mass movement. However, at a critical point of density there's no personal space left and people are in full body contact. In this situation, mass movement efficiently transmits extreme forces through the crowd - the Crowd Quake. It's like changing a compressible gas into an incompressible solid, but people aren't incompressible. This is why crowd disasters happen so suddenly, it's like crystallisation from a gas.
See: Crowd Disasters as Systemic Failures: Analysis of the Love Parade Disaster http://arxiv.org/abs/1302.1886
Stampede? I thought a stampede was when people get knocked down and other people, instead of helping them up, just step on them to get over to the exit. Get stepped on by a couple hundred people and you're going to suffer grievous damage.
Shutting down free speech with violence isn't fighting fascism. It IS fascism!
I guess you prefer niggers shouting?
You're joking, right? Emo faggot shit or pretentious electro twerps.
