Moshpits Simulation
- davidw 14y agoNot that realistic for low numbers of particles. Those guys would get their asses kicked for being jerks running around and crashing into people like that!
- thenipper 14y agoThey definitely wouldn't be wandering around semi-randomly like they do with a low density of particles. Depending on the genre, they'd probably end up towards the front pushing a few black circles into the stage.
- robryan 14y agoDepends if the band is trying to get a circle pit going it seems to be semi realistic. But in general yes I think people are generally either trying to get closer or fighting off others who are trying to get closer.
- unholycrab 14y agoFunny, that's exactly what I do in a mosh pit.
- Buzaga 14y agoYou see, the mosh pit is like formation of planets, the heavier and more hardcore elements will gravitate near to the melted center and the light and meek will quickly shy away from it. At the least in the moshpits I see in small gigs here in Brazil, the ones at the edge of the pit will generally be walling the melted elements because staying at the edge pushing the weirdos back to the pit is just as fun as being there ;p
- buster 14y agoI'm actually far more impressed (or stunned) that there is a paper for "Collective Motion of Moshers at Heavy Metal Concerts". Does this qualify as science?! Edit: Ah well, i always thought a paper would be like a diploma or similar, turns out it is a 2 and a half page article written by 4(!) people who watched youtube to simulate red dots in a mass of black dots. Anyway, i'm underwhelmed.
- DanBC 14y agoFeynman would study what interested him. We got some valuable work because he happened to wonder why X does Z. So long as the work is rigorous there's nothing wrong with studying collective motion of moshers at heavy metal concerts.
- obviouslygreen 14y agoAgreed... my initial reaction to this was "maybe this will explain that Slipknot concert!" It doesn't have to be world-changing or life-saving to be interesting (though those things certainly don't hurt... usually).
- buster 14y agoTo me it looks like it's ridiculing science papers.. 4 students writing 2 and a half pages about "MASHers", with a bunch of youtube links as source material. Yeah, science! The fact that the story is prominently posted by dailymail filed under "sciencetech" is ridiculous as well. Call me when you find stadiums build on Jesse Silverbergs great principle of MASHers, that save so many lives. To me it's a shame that this appears publicly posted on a universities site. I suppose that, for this to happen, a Professor must have agreed and supported this paper.. ugh. P.S.: I do understand very well that simulation of crowds, especially in buildings, is very important but i feel that this is making fun of serious scientists putting real effort into such work.
- obviouslygreen 14y agoPoint taken. I should have paid more attention, I did not realize this was being passed off as something like that.
- buster 14y agoIt would certainly be interesting to hear Feynmans opinion of a 2 page "science" paper about drunken heavy metal fans smashing their heads together :P

- Tyr42 14y agoIt's neat, I can get a flow going from left to right and it manages to stay stable. Doesn't seem useful till we have torodial moshpit though.
- artto 14y agoIf you increase the box size, it just becomes a bunch of idiots running around on a large field and some people watching them.
- BrianEatWorld 14y agoI wonder if they properly controlled for the type of concert. In my experience, moshing will vary by genre with hardcore moshers tending to be more independent (see: windmills and kung-fu kicks). I also recently swapped coasts and noticed that West Coast pits seem to seek out the torodial "circle pit", while East Coast pits a more chaotic. It is a neat idea for a paper, but it seems like it needs a bit more thought to be useful for real-world applications.
- gusgordon 14y agoThis seems like it can be used to simulate a liquid well. If gravity acceleration is added, then the whole thing is blurred and a threshold applied, you can get something like this: http://www.patrickmatte.com/stuff/physicsLiquid/ http://www.patrickmatte.com/stuff/physicsLiquid/
- pud 14y agoThe math behind it, from "Collective Motion of Moshers at Heavy Metal Concerts" http://arxiv.org/pdf/1302.1886v1.pdf http://arxiv.org/pdf/1302.1886v1.pdf
- mark_story 14y agoYay HORSE the band as a soundtrack!
- SimianLogic2 14y agoInteresting that they broke it down into only two types of particles: moshing and not-moshing. In my experience there should be a third particle for the "border guards" -- the people who help keep the shape of the pit and actively push people back in (as opposed to a non-mosher particle which merely absorbs hits).
- colbyh 14y agoDon't forget the natural variability of said border guards who might, should their favorite song enter the scenario, join the moshing group.
- wavesounds 14y agoAlso theres people who will avoid the moshers unless specifically behind 'border guards' - in this simulation everyone essentially acts as border guards; the grey dots dont try to avoid the red just hold their ground. Really cool app though!
- scheff 14y agoMissing is - 1. Wall of death. 2. Collapse of the mosh when one person trips over. 3. Crowd surfers and the effects of a boot to the head.
- brianmwaters 14y agoGotta love the handful of random grey dots lost within the mosh pit. I think we've all been there.
- newobj 14y agoToo late to complain about lack of circle pit and wall of death. However, I will point out that it kind of seems like it assumes a uniformity of violence, whereas empirically speaking you always have at least one person who is just seriously dangerous either due to intoxication or mental issues combined with large stature/strength. This person both repels others with a stronger force as well as draws in/invites the odd skirmish. Also missing is the fact that in certain scenarios, the non-moshers will aggressively shove the moshers back into the pit, versus here where it seems like they simply tolerate them to whatever extent packing will allow.
- shanev 14y agoMy thinking exactly. Cool science project, but doesn't resemble a real life pit at all. The circle pit and people pushing along the perimeter are required.
- doktrin 14y agohaha. Maybe I got caught up watching this a little longer than you guys, but at times the pattern does begin emulating a circle pit. Both directions. It's sort of hard to determine a "push" from the perspective of spheres, but IIRC I saw some of that behavior as well. I mean pushing insofar as red pieces would occasionally move erratically away from the walls. I do agree about the lone mad rager acting as an unstable epicenter, though. That's key behavior, and something I did not notice in this simulation.
- jiggy2011 14y agoYes, the most interesting thing about moshpit behavior is how it expands and contracts. There's not a constant level of activity either, things will often calm down during a verse to reignite during the chorus.
